Review #65: Asus TUF Gaming A15 Laptop (Ryzen 7 4800H | RTX 2060) ★★★★✭

 Team Red + Team Green - A killer combination!


Introduction:

Ever since Y2K, when AMD stole the limelight for a bit with breaking the 1 GHz barrier and releasing AMD64, AMD as a company failed to impress on me the need to purchase their products. I had opted for Intel just prior to the Athlon breakthrough and every upgrade cycle of 4-5 years led me to opt for Intel. Hence, I was simply enthralled at switching to Team Red after nearly two decades of being stuck with Team Blue. My GPU always has been Team Green but with the integrated Vega 7, there is a dash of Red over there as well.

The Choice:

During the holiday sale 2020, it was between this and the Acer Predator Helios 300 for the princely sum of "not quite" one lakh INR. I could see the reviews racking up for the Core i7 variant on Flipkart and I had even purchased the same but cancelled it as soon as I came across this Renoir masterpiece. It helped that Amazon also offered a much higher exchange price for an old laptop that was lying around, compared to Flipkart.

To put it straight, the Helios 300 has only one thing going for it compared to this one and that is the screen. On the flip side, this comes with a monster CPU, DDR4-3200, a 2000+ Mbps 1 TB SSD from Western Digital, a large 90 Wh battery, lighter weight, higher travel keyboard and about as good a cooling solution as the Helios. It also looks more professional than the Helios, so you can use it in formal environments without having people snickering at you. So overall, it is a win for the A15 over the Helios 300.

Display:

To address the elephant in the room, Asus gimped on the screen, using a Panda panel that has only about 65% sRGB colour gamut and >20 ms response time with quite some screen flex. It pales (no pun intended) in comparison to the 90% sRGB panel with 3ms response time on the Helios, but that is about it. I still managed to get popping colours out of it by increasing the saturation on Radeon Software and calibrating the display from within Windows. Sure, it throws accuracy out of the window in favour of something eye-pleasing but I am not looking to do any colour-work on it and even otherwise, I am looking to connect it to my 120 Hz 4K TV at home for gaming. I am unsure about it, but with the HDMI or DisplayPort output being driven by Vega, it should also support FreeSync directly compared to laptops having output routed through the Intel GPU.

Hardware:


The primary reason for getting this laptop is the Ryzen 4000 series. The 4800H puts the Core i7 to shame. I ran Cinebench after updating the system and without any tweaks. It registered nearly 500 on the single core and 4386 on the multi core, that even the Core i9-9980HK can't touch in most laptops, due to it being a blast furnace rather than a processor. The 4800H did not even touch 80 degrees on the Cinebench multi-core test. It did go past 90 on Firestrike but it never thermally throttled whereas the under-volted 9980HK in my earlier laptop hit 100 degrees within seconds and throttled like it was being asphyxiated.

The RTX 2060 is also the 2020 "refresh" variant with the 1.25V GDDR6 and higher TDP. It passed 15,000 on Firestrike on the first run but with the CPU running much cooler, it opens up the possibility of over-clocking the GPU farther than you can on an Intel machine.

Among other points, the machine ran without much noise on the benchmarks, but I expect it to reach whirring heights with demanding games, something that is to be expected of most gaming laptops. I haven’t checked the battery life and probably never will over the life of the laptop, as I always used it plugged, but the 90 Wh battery with the 4800H will provide a longer battery life than any Intel gaming laptop. The lonely USB 2.0 port on the right-hand side is a bit of a let-down but I have my fingerprint reader permanently plugged in so that I can use Windows Hello. Not having TB3 is also disappointing but I can’t see myself needing it over the lifespan of the laptop as DLSS will most probably help with higher resolutions in the near future.

Tweaking:

As expected, the UEFI on the laptop is barebone. AMD also doesn't support Ryzen Master on laptops, leaving it to OEMs to decide on the thermal envelope. That leaves Ryzen Controller as a tool of choice as it has experimental 4000-series support but with it currently being limited to STAPM settings, it is more likely to be needed to extract more performance rather than to lower temperatures, and thus is not the need of the hour.

However, as I mentioned previously, there is light at the end of the tunnel in terms of extracting more performance from the GPU. As the following 3DMark screenshots indicate, the GPU is able to provide 6-7% more performance using Auto-Overclock at the loss of less than 1% CPU performance. The GPU temperatures too are similar, though the CPU temperature does go up by 4-5 degrees at idle and 2-3% degrees at full load, but still does not throttle.

Warranty:

The unit received from Amazon was manufactured just 2 weeks before as per the warranty registration date. It can be changed to the invoice date by providing Asus with the invoice and a photo of the laptop serial number. An additional year of warranty, after using the 10% off code provided with the laptop, costs about $35 which is quite respectable.

Conclusion:

To sum it up, at the sale price, you can only go wrong with a gaming laptop if you choose Intel. Asus got most things right apart from the screen which is gut-wrenching but not a deal breaker, especially if you use a monitor or TV. In this case, it is what’s inside that counts and this thing is as TUF as it gets.

P.S.: It comes with a huge 16A plug that would probably go well with a microwave in the kitchen. Thankfully, the power adapter has a standard connector as a desktop PSU, so I was able to connect a 16A cable with the regular sized plug. You can also probably get away with a lower amperage cable but it is best to get a 16A one if you can.

Musing #73: Raspberry Pi 4B - SD Card vs SSD



Earlier this year, I bid finally bid adieu to my Raspberry Pi 2 in favour of the Raspberry Pi 4B. The RPi 4B certainly opens up new horizons with its additional power, though I don't suppose it is a desktop replacement as some marketing material would have you believe. I couldn't care less about that aspect as it is meant to be more of a hobbyist product, though I did switch over to MATE desktop environment from the kiddish-looking LXDE environment that the Raspberry Pi OS comes with by default.

What I was looking for most is the general increase in performance and with the BCM2836 SoC in the Pi 2 v1.1 not supporting USB boot, this was the first time I could boot off the USB. I immediately jumped on to the 64-bit beta back in May along with the EEPROM update that allowed booting off a USB drive.

I already had a Sandisk X110 M.2 SSD with me from an older tablet and a M.2 to USB enclosure. Unfortunately, I quickly realised that the enclosure was not up to the task as even loading the boot files failed repeatedly. It seems the controller on a cheap enclosure isn't really that good (who would have thought?), so it meant getting another one instead. I went with a ORICO one this time, not expecting it to be great but at least better than the one I had since it cost 3 times as much. Sure enough, it did the job.

So how fast is the SSD over the SD card? Unsurprisingly, it is quite significant. The lower power of the processor on the Pi gives a better idea of the difference made by SSD alone, though with it being limited to a shared 5 Gbps interface, the full extent wouldn't be evident if you plug in another USB 3 device or wastefully plug in a NVMe SSD instead of a NGFF one.

Long story short, unless you need your Pi to occupy as much less space as possible, it makes sense to boot off a SSD instead of a SD card. Also, if you have a good case, like the Argon One I picked up recently, it is possible to overclock it to the maximum 2.147 GHz without voiding the warranty and still keep the temperatures lower than the stock frequency without cooling. All this does tempt me to give the Pi a go as a daily driver, but for now there are many other creative uses for the device that take precedence. Until next time, Godspeed!

Poetry #15: Ashes and ember


The flames that shine the brightest

May not last the longest

But the radiance is seldom forgotten

By all those who are beholden

 

You touched the lives of many

In every nook and cranny

With the smile of a thousand suns

That even time cannot outrun

 

Thank you for all the moments

That will stay treasured and golden

There was so much more to say

If only you were to stay

 

A goodbye that wasn’t due

If only this wasn’t true

Shweta, we shall forever remember

Beyond the ashes and ember


Review #64: Samsung Galaxy Buds+ (4-month review) ★★★★✬



I left my previous post in a bit of a cliff-hanger but then things have changed a lot since then. One would imagine being stuck at home would offer better opportunities to engage in one's passion but quite the opposite turns out to be true. 2020 hasn't been an easy ride and no one could have seen what's coming, but that's the story of life, our life.

To pick up from where I left off nearly 4 months ago, I did pick up an alternative in the week following my previous post and the choice is reflected in the title of the post. You might recollect that it was a balance between price and quality for me and in that essence, the Buds+ hit it out of the park, provided you pick it up at the right price.

While even the renewed Jabra Elite 75t was priced at 10.3k INR ($138), I picked up the brand-new Buds+ at 8.5k INR ($114) and it is now priced even lower at 8.2k INR ($110). Granted you will have to find the means to pick it up from Samsung's corporate portal rather than the consumer one, but at that price, you can easily see why it makes a really compelling option. It is rare to have electronic items priced lower in India than in US, so it is good on Samsung to offer it at such a competitive price, albeit hidden from most consumers.


I picked up the blue variant simply on account of it not existing in the previous version. I am not particularly picky about colours, but this shade turns out to be quite "cool". There are new colour variants being released all the time, so you may have a personal preference but at release, this one was the only option if you didn't want to go with the non-colour black and white options.

The packaging is pretty standard by now for most true wireless earbuds but Samsung gets most of it right, starting with the USB Type-C support for the case. Speaking of the case, it is much smaller than what you might get with competitors and light at about 39g which was possible simply because Samsung managed to pack incredible battery life within the earbuds itself as against having multiple recharges provided by the case. 


There are 3 sizes of tips provided along with hooks and a Type-C cable. I had to go with the largest tips eventually to get a good fit and passive isolation, but it gets the job done. It may support one of the Comply foam tips if you prefer those, but I couldn't use my MA650 Wireless tips even though they were a much better fit, for the reason that the buds wouldn't fit in the case with those attached. A real bummer! Apart from the tips, the wingtips offer the extension required to lock the buds in place. I can see this to be a godsend for some people but it never worked for me. I get a snug fit in my right ear and a loose one in my left which irritates me to no end, but I guess you can't change your ears to suit devices and I wouldn't like to know about it if it's possible. Thankfully, the buds themselves are quite light at little over 6g as otherwise it would have been a hard time walking or running with them.


Going back to the point on battery life, the Buds+ boasts 11 hours of device battery life. That is a tall claim and one that I am inclined to believe based on anecdotal evidence as it is nigh impossible to have a 11-hour listening session. However, I went through a complete workday having the buds in ear or lying about and finished the day with 55% battery life with office calls and some music thrown in. The battery capacity figures are indicated above, and basic maths would indicate that the case offers a bit over a single charge, hence Samsung's claims of 22 hours listening time in total. 


The case itself has a multi-coloured charging indicator inside for the buds on the inside and the case on the outside which does a good job of indicating if the buds are being charged as well as the battery life of the case itself going from green to orange to red. Wireless charging support would also come in handy in case of emergencies if your phone happens to support the same which sadly isn't the case for my 7T.


One thing that has been consistent is Samsung's rate of updating the software which is good to see. The above screenshot on the left indicates the first update I downloaded straight out of the box and the second one indicates the latest update which happens to be the fourth one in 3 months since purchase, so a decent clip. A lot of the initial updates were focused on ambient noise and the latest ones have moved more towards stability. Even so, features have been added with time and the latest one is the seamless device connection, or at least the option to toggle it off which would come in handy when devices are fighting to take control over your buds, as is the case with Windows.


The "Labs" section is another one to access experimental features that Samsung feels is not ready for prime time. However, I found the edge double to be most useful, not for taping on the edge for volume control but rather the base of my ear and it works surprisingly well. The detection is done using the accelerometer, so it doesn't matter how you activate it. This gives rise to the possibility that some people might activate it by sudden ear movements, but it has been pretty flawless and convenient for me.



Continuing with the app interface, the above image is of the main page of the app and it gives an overview of all the available settings. The most visible change has been to the battery indicator where I have observed the battery life indicator being switched from displaying the individual level to a combined one. It is obvious that both buds may not have the same life based on connectivity and usage, so the individual bud display was better in that sense but I am pretty sure that a lot of people would have complained about the asymmetrical battery life as being a device issue and hence now we are probably looking at lower of the two battery lives which limits information as far as single bud usage is concerned. Unlike the 75t which uses a master-slave (leader-follower?) combination, the Buds+ is capable of being used independently and hence it is odder still that Samsung moved to a combined battery life indicator.

Apart from that there is a simple 6 preset equaliser present and I would have instead preferred at least a 5-band equaliser that is provided by Jabra. This limits the tweaking ability and I would assume a lot of people would go for the Bass boost option because this set is far from being as bass heavy as the Jabra Elite 75t. The other options are unlikely to be used much apart from probably the Touchpad one.


One might have expected more customization from a section dedicated to the Touchpad but only the touch and hold option is customizable out of which 'Ambient sound' is a must-have. Rest of the controls are pretty intuitive and doesn't take much time to getting used to. The Lock touchpad comes in handy when dozing off and I admit to making use of it a couple of times to good effect. Overall, having a capacitive touchpad is better than having to press physical buttons and +1 (see what I did there?) to Samsung for that.

I believe I have covered everything apart from the audio until now and a lot of people would chastise me for beating around the bush. However, sometimes it is best to keep the best for the last. To prevent any confusion, I am not talking about the audio being the best in its category but rather the best aspect of the device itself. It really holds up well for what it is. By that, I would like to clarify that it isn't at the same level as the Jabra Elite 75t but close to it. It can't punch bass to the same extent as the 75t and it has a smaller soundstage but otherwise the clarity is quite good. I am putting this in perspective of my use case which is using this on the move and in such instances, the higher audio quality doesn't matter much as I would altogether put down wireless buds if I am to enjoy the audio. Also, Samsung has significantly improved the microphone quality from its previous iteration by including 3 sets of it and it also does a good job when using the 'Ambient Noise' feature which I believe is a must-have for any TWS earbuds. On the flip side, the microphones are too sensitive and pick up the ambience to a great extent which is a shame as the passive isolation from the earbuds is quite good and the wearer is oblivious to the noise others complain about, unless 'Ambient Noise' is enabled in calls and even then you cannot do anything about it rather than apologise to the listener.

To address the elephant in the room, the Buds+ don't have any kind of aptX support. You will have to rely on AAC for most devices and that isn't a great option for Android. While the audio quality is still decent, the latency is atrocious for apps that are not tuned to synchronise the video as per the latency. Also, Windows does not support AAC and it means falling back on SBC which makes things even worse. Samsung's variable audio codec might be a good alternative to aptX but with it being limited to only Samsung devices, it isn't going to be a smooth ride for those who wish to use the Buds+ for everything. However, my use cases mainly involve music and watching video on apps that are designed to synchronise the video with the audio, so it hasn't been much of an issue. Also, while Spotify might sound poor with AAC and SBC, my music collection is mainly in FLAC and the AAC stream of it gets the job done when on the move.

To round it off, getting 90-95% of the performance of the 75t at just above 50% of the cost is too good to pass. You will lose the water and dust protection with the Buds+ only being classified as IPX2 and the audio quality is again a notch down from the 75t, but something that isn't going to be an issue when on the move. The battery life is phenomenal, and the look, feel and fit are much better than the 75t. It boils down to your use case and if it is about having a great set of wireless buds on the move, then this fits the bill perfectly. If you are someone transfixed with audio quality and active noise cancellation, this one isn't going to float your boat. But for the value conscious, there simply isn't a better option from a reputed company that cares to update its device beyond the initial purchase.

Review #63: Jabra Elite 75t True Wireless Earbuds (Amazon Renewed) ★★★★☆



This is the first time I purchased an Amazon Renewed product and trying out this service was at the back of my mind for quite some time. However, the primary reason was my lack of conviction in keeping the product and I didn't wish to create another open-box product just for the sake of it. The hesitation was borne out of the fact that I wasn't sure of the switch to True Wireless earbuds, with my RHA MA650 having served me well for over 2 years for my primary use case, which happens to be commute and office dreariness.

The item was priced at a 20% discount to the MRP of INR 14,999 which still seems a high price to pay considering the fact that you don't really know the condition of the product. With some bank discounts, I spent about 10.3k on the product, which was more palatable, but ideally the price should be around this mark anyway prior to any bank discounts.

The box was in fairly good condition but the signs of it being already being unboxed were pretty visible with the top cover being ripped off and the bottom being sealed with a fresh line of tape. Inside, all the contents were present as expected, though I later heard from the person doing the return pick-up that a lot of people tend to nick off the Type C cable, which does reduce my faith in humanity a bit. While the alternate tips were still sealed, the applied tips didn't look completely pristine and I took the precaution of cleaning them with rubbing alcohol. I am not sure about the reconditing checks touted on the Amazon website considering this and the fact that the buds were already on and displaying the low battery indicator on unboxing. The carry case had about 40% charge and in all it seems that the buds were at least used for a few days prior to return.


Coming to the product itself, the buds are quite light at about 5.5g each and didn't weigh heavy on the ear. The fit was quite good and the passive noise isolation was excellent, especially with music playing in the background. However, what takes the cake is the Hearthrough mode which allows ambient sound to stream in without much lag and is a godsend when walking around busy streets. It goes well with music at medium volume and made me realise that this is a feature I cannot do without on any true wireless earbuds.

Coming to the audio quality, the immediate thing that hits you is the bass. These earbuds are bass heavy by default but there is a way around it as the companion Jabra Sound+ app allows you to set a 5-band equaliser and turning down the base was my personal preference. Apart from that, the mids and the highs do well though I wouldn't say they were any better than the much cheaper MA650 wireless earphones I have been using on commute. That said, the quality is good for its size but then the sound stage is quite poor and is perhaps expected. The mics though are pretty good as borne by the passthrough and the call quality was more than passable. The battery life on the other hand wasn't exceptional and it would not be possible to go through a day without putting it in the case for charging when not using it.

At the end of the day (literally), I returned the earbuds primarily because it didn't seem to be worth its price in terms of audio quality. The convenience of it was undoubtedly remarkable but then that would apply to nearly all true wireless earbuds. I am not looking at ultimate sound quality because my use case for this is limited to commute, office and exercising. I prefer over-the-ear wired cans to this at my home when I really want to enjoy the music. My first experience of TWS earbuds has indicated that there is a specific use case for it, and I am certainly intent on picking up a pair soon, provided there is a better balance between the feature-set and the price.


Tutorial #23: Taming the beast (Dell XPS 7590 Core i9)


One of the significant purchases I made over the past 6 months is the Dell XPS 7590 with Intel's Coffee Lake Core i9-9980HK, Samsung's 32 GB DDR4-2667 RAM, Toshiba's 1 TB SSD, Nvidia's GTX 1650 and the crème de la crème that is the 4K OLED panel made by Samsung. But before you get any ideas, this is not a device that I would have otherwise purchased but for the fact that I found a single piece listed on Amazon 2 days prior to its official launch of the device at a price that was lesser than the 2019 Acer Helios 300. The risk was worth it as it came sealed with a valid 12-month Premium Plus support from Dell. There are instances in one's life where one doesn't mind getting lucky and this was certainly one of those.

Normally, I would be prompt in reviewing devices within the first few weeks of purchase. However, in this case I think I am too biased towards the device to perhaps put up a worthwhile review. Hence, I thought it better to post a tutorial that would be of some assistance to fellow users. One thing that I am certain of is that the hardware has outgrown the XPS chassis design over the years and the Core i9 pushes things a bit too far in terms of what the chassis is capable of handling thermally. Hence, I went on an optimisation quest with the intention of lowering the temperatures and increasing the overall efficiency of the device. I will own up to the fact that I don't intend to use the device on battery at all unless I am forced to but for that eventuality I decided to find a compromise which would at least provide stock performance at lower battery consumption as against higher performance when operating directly on AC.

The tool of choice in this case for the CPU is Throttlestop which offers significantly more tweaking potential than Intel's Extreme Tuning utility. As for the GPU, the mainstream tool to use is MSI Afterburner. However, in case of this GPU, I found that the temperature limit setting on MSI AB was locked for some reason even after unlocking all the advanced options and the Auto Overclocker resulted in far too frequent game crashes. Hence, I instead went ahead with Asus GPU Tweak II which allowed the GPU temperature target to be set upfront. By default, this is set to 75 Celsius and I instead bumped it to the stock value of GTX 1650 which is 87 Celsius. However, the idea in general is to still not exceed 75 Celsius during most strenuous tasks but to provide the headroom to exceed that if needed.

With this background, in the interest of time, I have decided to simply post the screenshots of the various screens from the tools since further elaboration on each parameter can be found on their respective forums. In case of the GPU, I eventually stuck with simply pushing up the clocks by 10% as undervolting using the frequency curve resulted in far too many instability issues. Is this the most optimum setting possible, most probably not. However, I believe this is the best setting I could identify with trial and error, as attested by the 88 unexpected reboots on record. I could certainly push the clocks and voltages quite a bit more but in general it led to instability and I am certainly no fan of BSODs. Another point to note is that while Asus GPU Tweak II can be set to start on reboot, Throttlestop requires additional effort in setting up the task scheduler which is what I have indicated below.

Starting Throttlestop on Login:

Throttlestop settings for AC profile:

Throttlestop settings for Battery profile:

Now to focus on the fruits of the labour or the pudding so to say. I am not a fan of benchmarks in general but in this case, I needed something to comparatively measure the impact of the changes and a few basic benchmarks provide the easiest reference in this case. Note that I ran all the benchmarks with only the discrete GPU enabled with the overclock settings, so it represents the worst possible scenario in case of thermals.

UserBenchmark:
This might not be the first benchmark utility that springs to mind but for the fact that it allows comparative analysis for similar hardware components and is of considerably short duration. In this case, the CPU came up at 97th percentile and the GPU at 100% percentile which, considering the fact that is mostly going up against much bulkier gaming laptops with much better thermals, is noteworthy. Overall, the CPU efficiency is excellent with the tweaks providing higher performance at lower power. The discrete GPU however doesn't scale up in terms of efficiency and while it is possible to get more performance out of it, it comes at a significant cost in terms of power and heat.

Cinebench:
Cinebench really pushes the CPU and is thus a good test of its ultimate performance. A sequence of 2 consecutive runs also pushes the CPU to its thermal limits. Not surprisingly then, the 1st run score of 3684 is more than 20% better than stock and even the 2nd consecutive run scores better than the stock settings with lower average temperatures.

Heaven:
This benchmark was run at the Extreme preset. As I have already mentioned previously, pushing the GPU doesn't really yield huge benefits in this constrained form factor as the any performance benefits come with equally higher power consumption and heat generation. However, as can be seen in the results, a 3% performance boost in Heaven comes with lower CPU temperatures and the GPU power consumption is lower even though it hasn't been undervolted. So, a win-win overall.

Lastly, how do these modifications fare with a modern game. I happen to have Hitman 2 installed at present, so I thought I'd give it a go with the in-built benchmarks which I frankly didn't find to be entirely consistent across different runs. But I believe it should give at least give an idea of what the laptop is now capable of, even though it is not meant to be a gaming laptop.
I set all the details to the maximum possible apart from lowering it a notch to 'High' for 'Level of Detail', 'SSAO' and 'Shadow Quality', besides turning 'Motion Blur' to 'Off'. The Mumbai benchmark produced a score of 70.95 FPS with CPU averaging at 79C and the GPU at 70C. The more demanding Miami benchmark chewed out 54.04 FPS with CPU/GPU temperatures averaging at 78C/69C respectively. A more than serviceable gaming machine if I may say so.

Sundry #14: 2020


I am alive, thank you for (not) asking. A single month hadn't passed by without a post until October of last year. The hiatus was brought about not due to a writer's block but it was simply a case of life any my arch nemesis time speeding by me. Anyway, can't wait to get going again as there are no shortage of topics to write about, just time.

You might have already observed a few minor changes if you have visited the site before. As the first change in this new decade, I have decided to drop ads from the blog, simply because I haven't earned a cent from them since their inclusion, on account of never crossing the minimum threshold. I suppose I was only filling up Google's coffers, so it makes sense to drop them altogether in favour of a better experience.

Also, since I post in dribs and drabs, I thought it would be good to have somthing that self-updates and thus, the news widget. Now you can be informed in more ways than one, though I suppose that really wouldn't be the reason to visit this blog.

I suppose I shall now take your leave and probably conjure up a topic worth reading over the next few days.

Musing #72: R.I.P. A50

Over the past few months, I had made multiple posts on the Samsung Galaxy A50, be it a short review, initial analysis of the super slow-mo or a guide about making the most of the mid-range hardware. Unfortunately, all average (good-ish?) things come to an end and in this case in ended with my A50 being lost. The driver of the vehicle in which the phone was left behind gave me some hope in picking up my call, but what followed left me with a little less faith in humanity.

However, life goes on and move on I have. At the same time, I have no emotional attachment to any material possession, so this post is not an eulogy on the A50 but rather a short post on what can be done to make the most of the situation where the phone is lost.

Samsung puts a fair amount of bloatware on its phones but one piece of software that is genuinely useful is "Find My Mobile". This feature is markedly better than what is offered by Google and there are several options for dealing with the lost device besides simply tracking it like erasing the device, ringing it, retrieving recent calls/messages and extending the battery life. Unfortunately, my trust in the driver led me to not immediately open the tracker which in turn ensured that the device was never again switched on with my account activated.


With the horse having bolted from the barn, there can be some solace found in rendering the device useless, well, as a phone at least. The Department of Telecommunications (DoT) in India launched the Central Equipment Identity Register (CEIR) earlier this month which is supposed to make the blocking of the lost phone as easy as snapping of fingers.

Unfortunately, as with any government initiative, things sound much better on paper and on websites than in reality. I went through the process of lodging a police complaint at the place where the phone was lost with the expectation of making the most of this lifeline afforded by the DoT in terms of being able to take some action on the lost device. As it turns out, while the website correctly verifies the IMEI using the dedicated tool, the form itself fails to submit with the error stating the absence of data for the IMEI. A really shoddy implementation by C-DOT backed by an equally appalling lack of response on social media. I would still give them the benefit of the doubt considering it has been launched as a pilot project, but hope they would be inclined to fix the website eventually.

Even every misfortune is worth the experience and I would say this is a lesson well learnt. A bit more practicality over trust in humanity might have saved the day. Hopefully, this post would equip you to better handle such a scenario in a far better manner than I did. See you until my next mobile adventure.

Tutorial #22: Optimal performance from the Samsung Galaxy A50 (or any mid-range device)


The demands from the hardware have arisen significantly with every passing year, which is only made worse by manufacturer-specific UIs adding an extra layer of cruft. While hardware capabilities increase demonstrably every year, the software demands more than negate the gains and ensure that even last year's flagship is not a safe bet anymore. However, not everyone needs the latest flagship device or wants to spend a small fortune for the extra processing power.

As I touched upon previously, my primary reason for getting the A50 was the large OLED screen. With gaming on the mobile out of the picture, all I really wanted was to not have a horrible user experience which becomes part and parcel of any mid-range device over time. Mi devices are most offending in that respect with MIUI but Samsung hasn't won itself any honors by bundling lots of promoted apps, some uninstallable, coupled with a Samsung Pay Mini card that interferes with the gesture system.

While adb commands offer a fair degree of control over the device, I prefer to root the device when possible to be able to customise it just that bit better with lesser hassles. The Samsung A50 has perhaps the unintended benefit of being able to boot into the rooted as well as the unrooted system at any point of time which kind of ensure the best of both worlds, if you are not looking to use rooted apps all the time.

With this, I present a step-by-step guide to setting up the device to run like it does when brand new, only better because of the uninstallation of all the bloatware. While it wouldn't make any of games run any faster than what the hardware allows it to, what it does is ensure that the phone is running optimally at any point of time, so no memory-hogs or sudden slow-downs or battery-drains.

1. Rooting the device (optional)

First the disclaimer. Rooting the A50 trips the Knox bit, so you are immediately foregoing device warranty as well as the ability to use any Knox-secured apps like Secure folder and Samsung Pass, though you can still run some Samsung apps like Pay Mini and Health.

For this, I will simply point you to John Wu's excellent tutorial. It has worked with every firmware released till date and allows you to upgrade to every new release while retaining your data, the downside being that you will have to download the entire firmware to do so as OTAs are no-go.

Also, as I mentioned previously, the peculiar partitioning and button combination allows one to boot in to either the rooted or the unrooted system. I personally prefer optimising the system in root mode but don't run it as daily driver as it has issues with WiFi disconnections and random reboots. However, the changes are carried over just fine to the unrooted system which is rock stable and has not rebooted randomly on me till date.

2. Installing Island and making it device admin

Island makes use of the 'Android for Work' feature to create a separate work profile for which it, and consequently you, are the admin. It can be made the device admin without root access provided you delete all other user accounts and make it the admin using adb commands. There is also the option of God Mode which essentially allows Island to control the Mainland apps.

3. Installing Greenify

However, Island by itself doesn't have a background service and it utilises Greenify for that purpose, unsurprisingly from the same developer. While Greenify can normally hibernate apps using Android Doze, the integration with Island takes it to the next level.

4. Deep Hibernation
The easiest way to ensure that apps undergo deep hibernation is to select the 'Auto-freeze with Greenify' option from within Island. This directly adds the app to the "Hibernation list" in Greenify with the 'Deep Hibernation (by Island)' option enabled. Alternately, one can manually add the app within Greenify and then select the same hibernation option.

5. Create 'Unfreeze' shortcut
Subsequent to selecting an app for Deep Hibernation within Island as mentioned in the previous step, it is a good idea to immediately select the 'Create Unfreeze & Launch Shortcut' option which does what it says. It allows you to directly launch the hibernated app but requires you to maintain the shortcut on the homescreen, iOS-style.

6. Create Hibernation Shortcut
Lastly, I would suggest selecting the 'Create Hibernation Shortcut' from the Greenify menu. This places a "Hibernate" shortcut on the home screen, selecting which immediately freezes all the apps for which 'Deep Hibernation (by Island)' has been selected while also queuing up for normal hibernation any other apps you might have selected within Greenify.

7. Profit
The screenshot above indicates my app drawer post-hibernation and as you can see, the "all-time" enabled apps don't even cover a single drawer page (the folders only contain about 4 apps each). At the end of the day, you really don't need Maps or Uber running all the time in the background and tracking your location while draining the battery. Another illustration is the immediate memory consumption which in this example goes from 951 MB free to 1.2 GB free, just by hibernating the currently running apps. The interface fluidity and memory consumption is certainly much better by having only a limited number of running apps at any point of time.
The other benefit is that you can run dual instances of nearly every app, independently within Mainland and Island. A tip over here - it is recommended to create a separate folder (or tab) within your launcher in which you can retain the Island apps that you wouldn't like to be frozen like the duplicates of Play Store or VPN apps. It simply makes the launcher look cleaner and perhaps helps prevent confusion in case the padlock symbol against the Island app icons doesn't work for you.

8. Loss

The only downside I have seen is that the apps don't come up for update on the Play Store unless they are enabled, so be sure to check the Play Store for updates every now and then. Also, as I mentioned previously, the hibernated apps altogether disappear from the launcher and don't reappear within the folder you might have assigned to them, as they are effectively seen as new apps by the launcher on every "unhibernation", though the app data is retained. Hence, the recommendation to create the unfreeze shortcuts on the home screen.

9. Conclusion

There can be some paranoia over having an app become the device admin, especially coming from China. However, I have previously interacted with the app developer over email and have found him to be polite while immediately addressing the issues reported by me.

If you simply want the benefits of an independent work profile, you can use the Test DPC app which allows you full control over the work profile as an admin. You can also use the open-source equivalent of Island known as Shelter.

However, neither of the apps integrate with Greenify like Island and neither are able to create a work profile when the Knox bit is tripped. Hence, in my case, it is the only feasible option to keep rogue Android apps in check.
