scroll stutter

Why is the scroll stutter in sensation or in Android in general? WM7 or iPhone has it smooth from their first phone release.. is it something to do with screen refresh rate? Or its more OS related? Dont tell me that your android is smooth as hell..
For example when i scroll the app drawer or the settings page, i see stutter. I admit that some places (in some ROM) its smooth but most places its not. For instance, if you pan photos, its smooth.. but you scroll settings it stutters.
From a noob perspective i am guessing iphone handles "everything" like a image.. so scrolling, zooming, panning is smooth like we do on photos.. and i guess android renders as text or something else... just my wild stupid guess..
And, is there a way to fix this? or the android OS needs to be re-written? I am upset because sensation is much higher configuration than iphone 3gs. But the stutter present in sensation (even with any ROM) is not in 3gs. So i dont beleive its hardware..
Is it the screen and the capacity touch technique used by apple? i saw one video where the iphone screen is performed almost 99% close to maximum touch accuracy and sensitivity than any other phones..
see the video below..
http://www.engadget.com/2010/03/24/moto-touchscreen-comparison-recruits-robotic-implements-for-heig/
so what do you developers think?
1) Touch screen itself
2) capacitive touch technique / code used by apple
3) screen refresh rate
4) GPU rendering
5) the way OS handles the screen and images
I cant think anything else from my noob brain.. but you developers can.. anything can be done to fix this? From OS perspective.. not like my 'contacts' scroll smooth but not the browser?!

its a matter of display, its well known fact that iFail has top notch displays, whats on the other hand, basically the only possitive fact on that thing. So yes it is Apple's screen, same goes for iPad. Btw as for WP7, i own HD7 and its even worse then old Touch Cruise

If its all about display, how come cheap replacement display units from online can achieve the same thing in iPhone?
It got a be something else...

It's because of hardware acceleration. Too lazy to explain it now
Swyped from my HTC Sensation

iPhone uses the graphics processor to handle everything, not just games/videos/flash. The whole front end (UI) uses the GPU (graphics processor) in order to make everything look smooth. In a way, this is sort of a limitation of android. Hopefully Ice Cream Sandwich fixes it (it is rumoured to).

Had to disagree. If its GPU rendering why the scroll is smooth in gallary? why not in other text related lists? Android uses GPU only in image and videos?

Im going to take a guess here but i think its to do with hardware acceleration, coding infact of the operating system like apple code all their interfaces to be bosted from the gpu, however with android i would say that not everything is coded to run with the gpu and actually id say there isn't anything but if someone could list the support for what is that would help. From what i can find only things like the internet browser and games are in sync with cpu and gpu.

Maybe it's not only related to GPU acceleration because I'm running InsertCoin 2.2.2 ROM and ADWLauncher EX. With the stock kernel that comes with IC 2.2.2 the appdrawer and pretty much everything else (with some exceptions) is "iPhone-smooth" but when I tried the Unity 7.0 kernel I saw much more stuttering.

A lot of it has to do with the fact that Android is multi-tasking, real multi-tasking that is. iOS and WP7 (I think, haven't touched it in forever cause it's complete trash) do some save-state multi-tasking crap. Should scrolling be affected by this? I don't think performance should ever be sacrificed. But I think a lot of stuttering in the Android UI comes from it thinking about so many things at once.

I think the gallery is hardware accelerated.
Some things are, some things aren't. Comparison for ya: use Opera then Use the stock browser. Opera is hardware accelerated (uses GPU for rendering). See how smooth it is? Now use the stock browser and compare.
Don't quote me on this, but I'm quite sure that is one of the biggies ICS is supposed to fix.
Somehow, I think Samsung has implemented hardware acceleration for the Browser on their Galaxy S and S II line of phones. This was first noticeable when the Galaxy S got upgraded from Eclair to Froyo: the browser was much smoother (albeit glitchier.... mind you, these don't necessarily go hand in hand, you can certainly make a hardware accelerated browser without the glitches).
I think that's as far as that goes. Try a hardware accelerated video player like diceplayer (free 14 day trial in the market). Try playing a 720p or even 1080p video with it. It'll be smooth. Now go into options and change the renderer to software. Now it won't be hardware accelerated. And it'll be a slideshow.

It seems to me more of an issue of software optimization. Try scrolling with Sense 3.0 and then compare it to a sense-less rom, completely different. And then things change again depending on which launcher you choose to use. The Sensation's hardware is completely capable of buttery-smooth scrolling, it's just a matter of time till developers iron out the small kinks in their roms.

it looks like everyone thinks GPU is the reason for ios smooth scrolling. well, do you really think the first iphone released in 2007 has a powerful GPU and used for everything ios does? the 2007 first iphone does the scrolling smooth and the 2011 sensation cannot. i strongly believe its not the hardware!!! i guess there something wrong in the basics and google let samsung and htc finding their own solutions for some of the apps they create on top of android.
something else is wrong and since the users are not greatly concerned (or expressed) about this, this is not fixed yet. I wish and hope ICS fix this issue somehow..

I have been trying to find additional information about this issue and the truth is that this is the only thread that people have actually started to talk about it. If i got this right you are refering to the periodic stutter within scrolling in android and not any asynchronous glitches. Even though many blame GPUs, non HW acc. interfaces and so on, to me its a clear cut situation of refresh rates/fps clashes. Its the same scenario of outputing a 24fps movie to 60Hz monitor where ull get the same kind of periodic stutter (something almost eliminated when u switch to 50Hz). Its got nothing to do with wether the monitor is CRT or LCD, it all comes down to refresh rate vs fps. Ive clearly seen that on my O2x where, hdmi mirroring (on a 60Hz FullHD TV) is perfectly fluent while there are some visible periodic stutters everywhere within the android enviroment, except 3D applications. And what do you know.. The O2X's display has a 72Hz refresh rate! Isnt there anywhere within the android OS where devs/users can have a go with this? Changing the ' transmiting' fps of the whole OS? Let me know what u think sundar

Getting Jelly Bean Buttery Smooth on the Infinity

Hi All,
Having owned a Galaxy Nexus, and getting Jelly Bean some time ago, I was expecting a lot more from Jelly Bean on the Infinity when it came to interface fluidity. My Galaxy Nexus was a lot smoother - transitions and the notification menu especially.
But then I started to notice - in apps - the notification menu is actually very smooth, but not at the home screen. All transitions were still very slow however.
I had quite a bit of a play around and nothing seemed to improve the performance. Then I think I found something, and I want some people to sanity check me. I use Apex launcher (performance was still just as slow with the default launcher). In it's options, you can disable wallpaper completely (which you cannot do on the default launcher).
When I do this...I finally get the greatly improved fluidity I was expecting. It's not perfect, but the difference is huge.
Is anyone else able to confirm this? It seems strange. I was not using live wallpapers...just a static wallpaper. How much difference can a wallpaper make?

High resolution wallpaper can slow down performances due to pictures taking space on the RAM. Thus high definition pictures can take quite a bit of data ~10MB. Though that doesn't seem to be a lot...

Well I have tried using a smaller image, but I expect Android is up-scaling it to full resolution. The anmation was much less smooth. Once I disabled the wallpaper again, animations were smooth again.
Does anyone else use Apex, or a launcher that can disable the wallpaper to test this?

I just use a 1x1 pixel of black, pretty much "removes" the need to draw the wallpaper.

Did you notice a perceivable improvement in performance as a result of using that wallpaper? It seems likely that Android will stretch that 1x1 pixel out to fill a large canvas of black, which may not give any performance increase so I would be interested to know.
I would also like to know if I am the only one noticing this difference? Maybe no one else really cares about it except for me!

I use Apex Launcher Pro. I notice no difference whether I'm using wallpaper or not. Everything seems nice and smooth to me.

I would say you shouldn't expect to much from the Infinity. The Nexus 7, being a Nexus device, will always be faster than any other devices out there. The Infinity with it lousy flash storage and a full HD screen will never be able to catch up with the Galaxy Nexus and Nexus 7 in terms of speed and fluidity.

I somewhat agree...it is certainly pushing a lot of pixels. So my expectations have not been too high. In fact, I have really been pleasantly surprised. However - for the most part - I don't believe the I/O limitations should be affecting this tablet that much. Obviously there will be some effect...the same issues I was seeing before are still present...but I still do expect some improvement from JB.
That said...I am actually seeing it...but only with the wallpaper disabled. This is what strikes me as odd...it is just a static background image...and it feels like a bug.
Maybe I should just keep it off and wait until Key Lime Pie?

Disabling unused apps and clearing their data helps a lot. If you cannot disable see if you can "uninstall updates" first after that you should be able to. If you're rooted like me you can disable even more stuff using Titanium BU.
The difference? Everything is loaded immediately on startup (i.e. no calender widget that takes 5 sec to show). Balanced mode feels like performance mode, I can go on.

What benefit is clearing a disabled app's data? My typical method for disabling something is to "freeze" it with TiBU and skip the OS menus altogether. Is there some additional benefit I could gain by clearing the frozen app's data too?

I was one of the people having slowness issues with their device but a couple of days later i figured it out. I went into the settings - apps - running and cached apps list. My ram was down to 100MB at some points. The 1GB of ram doesnt seem to be enough but we need to make due with what we got. So i installed Autostarts and disabled all the startup apps and any other apps i dont need when i change wifi state and all that other useless stuff. Google+ would run almost every 2 seconds, Maps aswell. So i disabled those apps from running at bootup and such. Now my available RAM is at 400MB constantly and it is running crazy fast. Opening the recent apps list and clearing those apps is super fast now. Also disabled some of the animation effects that jelly bean puts in. I personally am more concerned with performance then quality.

I noticed every app has notifications turned on by default (settings/apps). I don't know if it matters but I've been turning it off on everything I don't use notifications with.

I kinda laugh when I hear that it is pushing a lot of pixels so that's why it isn't smooth.... take the iPad 3 for example higher resolution, crappier specs and crappy iOS but it runs so smooth that it makes me want to trade in my infinite for it. I will have to jailbrake it to be able to do what I like but the experience will be better.... was just playing around with my friends iPad 3 and **** did I get me tinking.....

Dude, you should seriously do some homework on Anandtech to say that the iPad 3 has crappier specs. In term of SoCs and graphic performance, the A5X chip in the iPad 3 is the most powerful SoC on a tablet right now, even the upcoming Snapdragon S4 Pro is unable to compete with it. I don't have much love for Apple, but we need to consider facts. If you consider raw computing power, Tegra 3 is even behind the iPad 2. In order to drive that many pixels on the iPad 3, Apple had to include a humongous SoC as well as much bigger battery, which explains why the iPad 3 is thicker and takes longer to charge. For your information, Tegra 3 is still stuck with single-channel memory while the rest of the industry have moved on to dual-channel memory early this year (look at Snapdragon S4, Exynos 4, OMAP 4)
As much as I dislike the current situation, there is not much of a competition going on right now with SoC. Currently, on the tablet front, Apple has the most powerful SoC on the market (A5X). On the phone side, the A6 chip is also the most powerful SoC on a phone as well. I am severely disappointed at Qualcomm and nVidia for failing behind Apple so far on this front. Not much is known about Tegra 4, but they'd better bring some Kepler to it, otherwise nVidia will become irrelevant.

PiPo M9 Review / Discussion

Rooting instructions:
Type into google:
HTML:
site:pipo.cn upgrading procedure
Design and feel:
The tablet feels great, its one of the lightest tablets out on the market, only being beaten by the Samsung Galaxy Tab 2, the build quality is great despite the weight, it feels solid, doesn’t bend under tension and is in my opinion one of the best Chinese tablets build quality wise.
One negative note is that the speakers are on the back and sometimes you can accidently put your hands over them, or have them facing down on a table and therefore sound isn’t as loud, but once the speakers aren’t covered they are one of the best quality speakers on the market.
In my opinion I don’t really like the design on the back, though my PiPo M9 will be in a fulltime case when it arrives. Its just a personal opinion as I’m not a fan of the Toshiba like backing.
Gaming:
Gaming is great overall, I tested apps such as Citadel, Real Racing 3, Bejeweled, Temple run 2 etc. I didn’t notice any lag in the actual gameplay while playing, but I did notice some lag which wasn’t noticeable to the normal person on the cut scenes of Real Racing 3, which only lasted about half a second, and were fixed once I rooted the device and overclocked it a bit.
Web browsing / PDF browsing:
Web browsing is pretty fast and snappy, but most of it is dependent on your internet speeds. Websites such as cnn.com loaded fine, zooming in and out there was no lag, watching online videos no lag, but some poorly coded websites like perthnow.com struggled, but this would have been the same on every single tablet.
PDF browsing is also lag free apart from zooming in really far, where it takes a second to focus the text so it looks crisp. This wouldn’t be an issue on a high resolution screen like the Nexus 10 or iPad 4, but for the price is pretty good. I’m not sure why you would be zooming in that much in real life though.
Battery life:
Generally the battery has been one of the impressive sides of this tablet. With wifi off, it loses about 1% every 8 hours on standby, with wireless on while in standby it loses about 5-10% every 8 hours. My first day with the tablet doing benchmarks and other stuff, after about 4-6 hours it was only down to about 45% which is pretty impressive. There was no issue with drainage etc. but bare in mind I’m on the newer March 19 firmware.
Android Experience:
Its snappy, works great. I used the Nova Launcher on mine as I was sick of clicking the top right corner to get to the list of apps. Most apps work great, I rooted the device so I could download mobile apps, as there still isn’t much tablet made apps or websites in general.
Price:
$250 for a quad core, 2GB ram, semi high resolution screen? This tablet is defiantly a good buy, and beats most tablets out there on the market. It will shine past high resolution tablets such as the Onda V972 which lags in HD mode and its only real competition is past the $300 mark.
Overall:
8/10 – A great buy for the price. A 10.1 inch quad core 2Gb tablet, what more could you ask for? Though 1 wish is that I hope 4.2 Android comes out with the new tablet features. Camera shouldn’t be an issue as most phone camera beat the tablets out there anyways.
It’s a great buy for almost everyone, but I wouldn’t recommend buying it for a geek or a tech savvy person as they will quickly pick up the small amounts of lag which might happen, which isn’t just isolated to this device.
Good points:
Minimalistic design
Great speakers
Android 4.1.1 Jellybean
Fast and responsive
Bad points:
Poor camera quality
Speakers on the back
If you're interested in where I bought my tablet from its from spemall
If you have any questions, or tests you would like me to do, please don't hesitate to ask and when I have time I will do those tests.

Hi. What speed do you overclock it to and what app do you use to overclock it? Are you using the stock firmware, only rooted?
I've seen some video showing it lagging in Real Racing 3, worse than the Onda V972 which has a larger resolution albeit with more powerful GPU. You said you do not experience any lag in gameplay?
If you have the time, maybe post some benchmark score of Antutu and 3DMark

I actually have it on 1.6ghz using rom toolbox or something. I'm using the 19th of March firmware.
I noticed lag on the cut scenes of Real Racing 3 which wasn't an issue when I changed the CPU to performance instead of on demand. But the actual driving gameplay is no lag, but sometimes the cutscenes have lag... but thats mainly because real racing 3 is badly coded.

Thanks for the info. So changing the governor to performance is enough to make it run smoother. Have you tried actually overclocking it just for kicks? . IIRC, the RK3188 is initially rated at 1.8 GHz
I'm very interested in buying this tablet, but rather concerned about the initial performance review. I realize RR3 is not a good benchmark, but seeing some tablets using the Exynos 4412, which use the same Mali GPU with lower clock can run RR3 better makes me a bit worried. Hopefully it'll get better as the firmware matures.
Anyway, just saw that JB 4.2 update is in the works at http://blog.geekbuying.com/, interesting

Great news about 4.2! Yeh, RR3 is poorly optimized and coded for MOST devices... the Exynos 4412 is a popular Samsung CPU used in its tablets which is why RR3 runs better on that... because its optmized for it... (the amount of Samsung users who would be mad - haha). So yeh, its not because its a bad CPU, its bad relative to the popular ones which most games are optimized for.
Waiting for a custom kernel to come out before overclocking.

What's strange to me is, the RK3188 beats the Exynos hands down in both CPU and GPU department. I'm no expert on this but, just by comparing raw power, the RK3188 should beat the exynos in every apps. I think Samsung just got a much more mature and solid firmware at this point

I'm waiting for a group buy to end to acquire one of these tablets.
I have a question regarding the screen performance while in the street with day light. How does it behave?
Is it like most smartphones that when we step outside we can see a thing?
I have seen many reviews but non speaks about this...

Its pretty standard with mobiles... on brightest setting, in direct sunlight, like every other device you won't be able to see much.

With Samsung's and HTC's mobiles this doesn't happen...

I'm a bit disappointed with these Android compilation they install in Pipo M9.
It’s missing a ton of features that are native of Android ICS and JB.
For example:
1. Shortcut widgets from pull down menu should work to turn on/off the respective features.
Instead when clicked they take us to settings.
2. We should also be able to select, add or remove which widgets to show in that “pull down” menu.
We don't have this option
3. No Auto rotation on home screens with native launcher.
With 3rd party launcher this is possible....
4. Using the native launcher, not possible do we add/remove home screens?
Actually the native launcher does not allow a single customization!!!!!!!!!!!!!!!!
5. Native camera app is extremely poor and almost don't have any options.
Also, no option to choose where to save the photos and videos, such as on External SD Card.
6. No battery percentage icon as alternative as we have natively in ICS and JB roms.
7. On look screen the slide to unlock feature only allow the option to unlock.
In ICS and JB this "circle" has more options and in some cases we can also customize it. Here is just to unlock.
8. Honestly I just can't understand the system folder hierarchy nor the files and their settings, therefore I tried to do some changes and just don't know what to do. I do some MOD and DEV with Huawei and Samsung but this **** I never see!!
And so on and so on and so on....
Overall I'm extremely happy with the tablet but completely disappointed with this ****y and completely Android firmware they have INVENTED to install in this tablet.
This screems for real Dev works

Just found it here

I've had this tablet for a good 3+ months now and so far no issues. I have rooted the phone following the process the OP mentioned above (Pipo instructions on how to upgrade firmware) and used this firmware (JB 4.2.2) ---> M9 software_english version_20130529（no need key); it's actually the third link posted.
I also have Nova Launcher and I will have to say the price I paid for it is very much well worth it. It's actually bang for the buck one of the best out there. It's one of the few Chinese tablets with (as of now) with bluetooth and a pseudo GPS (E-Compass). The OTG function also gives it 3G capability among other things.

Upgrading Procedure
I personally used moborobo to download and install all the drivers you need in order to root it properly, then I followed the instructions given above.

looks good but for a 10" would like a higher resolution screen, although that brings other issues like higher power consumption for the screen, and requiring a faster GPU which again uses more power.

I use my Pipo M9 a lot for reading e-books and watching videos and it's actually very good. I was on the fence for the same reasons you bring up; but seriously for the size, the resolution is good enough. Technically a 10" screen with a 720p resolution is good enough since I also game and I know that a 1080p screen on a 24" is good enough as well. I also know that anything higher than 24"; 1200p and 1440p are the best options, but that's another topic all together.
Of course, this is just my opinion and everyone will have their preference.

They way I did it was by flashing a pre-rooted rom (riley rom 1.7 with sdk 2.0). In the meantime, I had to ditch riley rom 1.7 and flashed riley rom 1.6 cause I had an annoying flickering display issue. With this rom, the issue is still there, but only occurs if I set brightness lower than 20 or 25%.
I honestly didn't keep the tablet with stock rom long enough to see if the flickering was already there... anyone else having flickering?

They way I did it was by flashing a pre-rooted rom (riley rom 1.7 with sdk 2.0). In the meantime, I had to ditch riley rom 1.7 and flashed riley rom 1.6 cause I had an annoying flickering display issue. With this rom, the issue is still there, but only occurs if I set brightness lower than 20 or 25%.
I honestly didn't keep the tablet with stock rom long enough to see if the flickering was already there... anyone else having flickering?

I use Sumvision Cyclone Voyager 2 4.2 v1 (GB, Incl. Root) by Hejira , and the flickering issue is in alot of roms to be honest, at moment anything lower than 50% causes the flickering for me, but that aside , this is a fantastic tablet.

Stuttering in games

Anyone notice that some graphic intensive games stutter? I'm not talking about framerate. This also happens on my Z2 tablet.
Running the games side by side my LG G2, The G2 is noticeably smoother. Running benchmarks side by side, The G2 is smoother again, but The Z3 scores higher.
Current games I'm playing are:
Riptide GP 2
Dead trigger 2
Slingshot Braves
Update 07/09/2016: I'm now using a Z5 and experiencing the same. My old LG G2 is smoother.

I havnt had any prolems so far. Ive play asphault 8, modern combat and GTA pretty flawlessly. Are you using heavy launchers? I also use a taskmanager to close everything prior to gaming. (ive done this with all my devices not just my z3)

I'm using the default launcher.
I'll Try Asphalt 8 later today.
Thanks.

Must say I have not noticed stuttering like you mention, I will also try Asphalt 8 and see how it fairs.
My bench marks 3d is smooth, and my device on Antutu tops the 3d default scores.
I have though made a couple of tweaks.
Here they are and see if it helps;
Go to settings, click about phone 10 times (or until you become a developer)
Go into developer options
Go down to Hardware-Accelerated rendering
Tick force GPU rendering
And Disable HW overlays.
See how you go after that.

Force GPU rendering and Disabling HW overlays did not make a difference.
I just tried Asphalt 8 on my Z3, Z2 tablet, and my fiance's Z3 compact, and it stutters like crazy. Much more than Riptide GP 2. Don't get me wrong, the games are playable, but much more enjoyable on my older LG G2.

It could be heat or game related, My LG G2 never stuttered either and the Z3 for me has stuttered only in PlayStore of all places but a restart fixed that.

Hey mate i have been scouring the net for an answer to exactly the same problem you are having. Virtually every game has some intermittent stuttering which is pretty consistently occuring every few seconds so as you say games are very playable but dont feel smooth.
I have tried asphalt 8, zen pinball, Pinball Arcade , real racing 3 and none feel completely smooth. I thought maybe that real racing 3 may have been too graphically intense for the z3 but after reading so many reports from other z3 users on how good the game played on their phones it made me start looking for a solution. Pinball arcade and zen really sealed the deal for me about maybe something wasnt quite right though as these 2 games should pose absolutely no problem for any modern device (my vita vetsion side by side looks much smoother) but the ball will stutter every so often too.
If you find a solution i would really like to know what you did as i am new to android and everything ive read to try hasnt helped.

Possibly it's related to the resolution. The Z3 has 1080 x 1920, whereas the ps vita is only 960 × 544; around a quarter of the size. I do think it's a weakness of modern phones; I'd be a lot happier with a lower resolution. It's not as if the S3 had any problems with its 720 x 1280. I think it's a bit like the megapixel race on DSLRs; bigger is better, and damn the other problems (noise, image size on cameras; speed, battery, asset storage space on phones).

Doesn't seem to be related to resolution, as the same happens on my fiancé's Z3 compact. Also, the same games runs smooth on my LG G2.
I'm pretty sure it has to do With Sony's ROM since it's happening on my Z3, Z2 tablet, and Z3 compact. The people that report no stuttering is probably not as sensitive to it as some of us are.

I think the Sony ROM is running a more conservative setting or something because everything seems to be a little slow on the Z3. Battery saving method on Sony's part I assume.

Probably the kernel tuning. I've noticed it too.

Maybe Sony is more aggressive than LG with the thermal protection in the kernel. Even on the LG G2 if you disabled thermal protection it got rid of any stutters that were there, though not safe in the long run.

Guys do you think they will solve it by android L relase?

It will probably improve a bit because the new OS will be more efficient, and also better battery life.

Feel free to chuck up a video of the problem; I'm writing a game, so perhaps I could reproduce it if I had some idea what's causing it.

I remember having this problem with my Droid DNA when the Moto X rocking the same processor was smooth, regardless of framerate. Definitely firmware/video driver/kernel related. It can be most easily witnessed in games with a lot of scrolling or fluid motion, looking like a hitch or frame drop.

Thanks. I'll get a video of the Z3 and G2 side by side running Riptide GP2 tonight.

Ahh yes, i play asphalt 8 quite a bit, and while it doesn't lag, it definitely stutters a ton. I'm coming from an ascend mate 2 and even that runs it a bit better! i'm sure it all comes down to the heat/kernel settings. what's odd is when im playing need for speed, it's extremely smooth, but the phone definitely gets way hotter than it does when i play asphalt 8.

Sorry for the delay. My Canon camera crapped out on me. I ended up having to use my GoPro Hero3. Sorry for the image quality, GoPro sucks bad on everything except outdoor activities.
Top is LG G2 and bottom is Z3.
Edit: Youtube is horrible. I suggest downloading via Dropbox link.

In the LG G2 you could disable the Thermal throttling and manually set clock speed for thermal states in Trickster Kernel settings app. I suppose you could do the same here.

MiA1 GPU Artifacting in GTA SA

I just got my Mi A1 and am loving it so far. Im coming form a 2013 Nexus 5 that's battery was soo worn it only held 1500mAh on a good day. So everything about this phone has been solid till I launched GTA:SA from the app store. The game runs significantly better than it did on my Nexus 5 in terms of frame rate consistency and overall headroom to bump up settings but I'm noticing some serious graphic artifact issues regardless of what settings I use. They seem to appear as polygons get stretched and over large portions of the screen. I've seen similar things happen on PC graphics chips when overheating / poor traces however this is a new phone and seems to be software related as other games don't seem to reproduce the issue.
(intended on posting photo's but Im new to XDA forums and am unable to have links)
My goal in making this thread is to find out if anyone else is experiencing a similar issue with this specific title (official off playstore) or worst case; in other games. I tested Real Racing 3 and Simple Planes and PUBG (all full 3D titles) and all ran exceptionally well without any graphic artifacts. I don't believe this is an isolated case as the few video's that exist on youtube of GTA:SA played on this device seem to show similar visual glitches that were not present on my weaker and older Nexus 5. In addition, could it be the OREO 8.0 update that causes these issues? The only other clues I have found are a small handful of device-specifc reviews saying their games crash on missions and like one review complaining about the artifacting. Any information / advice on settings would be helpful!
Thanks all!

This problem is not happening on our device only fyi. From what I've seen, although I may be wrong for not researching enough, it happens on any device running Nougat or newer.

First thing first gta sa is not android platform game it's a console game I don't know about how much its in size but I guess it's almost 5GB maybe. Rockstar did compressed game for provide it on android (I'm not a fan of this game) I seen that game when my fiends playing and noticed some hiccups on ps2 console too those are the graphics hiccups so you can aspect them on android too, because it's ported not developed for android.
Talking about android gaming it's smooth (on mi a1) android games developer provide their best, for example need for speed Hot Pursuit is created from scratch not ported by EA Games and on android there some GPU limitations (console vs potable device gaming) thats why we are not able to play every single game on our devices when we redirect from any web browser to playstore so playstore said that game is not for your device etc. (resident evil 5)
As I can see that game is updated last in 2015 and its not optimized for newer android with newest drivers. When I compare my mi a1 gaming and Samsung galaxy s2 (almost 5 year older device) in gaming performance there is no change (on stock ROMs) like real racing 3, plants vs zombies 2, clash of clan, asphalt 8,dead trigger 2 whereas both devices are not same on software and hardware level but they run smooth.

What a shame.

Yeah this seems to be the case from what im seeing too. Welp, thats a shame. I mean it ran fine prior. I tried to adjust some visual settings to try my best to minimize the issue. In addition i read that multiple iOS users have had similar issues. Here are hopes that some android updates and or driver related updates do some good for this game. It's a fantastic title and amazing to have on the go. Runs at a solid framerate too on the MiA1 regardless of graphic settings so here are hopes that it gets resolved in the future.

It's not only Mi A1 problem and even not only Snapdragon/Adreno. I experience exactly same artifacts on Honor V10 with Mali GPU. Also it sometimes just crashes after few minutes of gaming.

I've faced the same issue on both on and off playstore. Had to return the game because of it
The game runs well enough, but the glitches make it look _very_ unappealing. Strangely, the glitching increases when I drop down the settings. When I max out the settings, the glitches are less frequent, but it lags and stutters a bit (maybe it needs an 8xx processor for fluid gameplay in Ultra.)

Now doubt gta 5 is one of best and my most favorite game on the internet. I am playing it since day 1 but now I am facing a lot of issues while playing it through gta 5 apk. Hopefully these will be fixed and I will start it again soon.

The first name in such a game is Grand Theft Auto. The most popular and iconic game in the GTA series developed by Rockstar games. Peoples from all walks of life have played this game all over the world. Great character and useful strategy as well as a world where you start your journey is one of the highlights of this game.
Even today, the game is going to a new level of success, so we need to enjoy the game along with the creative thinking. We are currently expanding our interest in this series through GTA 5 Android APK Download which attracts a large number of users.
