[Q] High CPU usage by a single app - Galaxy S II Q&A, Help & Troubleshooting

Hi,
I have a S2, rooted and still using stock ROM
I ran a few games from gamesloft (eternal legacy, rainbow 6 HD) and the apps just hang. i also ran a facebook game and it also hang
during these hang time, i notice that every time the CPU usage is very high (red font, > 40%)
It is weird because these game (especially gamesloft) had been released to less superior hw spec phone and they are running without problems
Example my friend's galaxy S 1 can run the eternal legacy which has theoritically half the computing power of S 2
Can anyone advice what can be the issue here?

i also encounterd this with "Heavy Gunner" and Gun "bros" he games are stuck and cpu utilization is 100%,no other apps online..thats sooo odd becuase i used to
play this game in my brother's "Xperia Arc" with no problems at all.

[Q] Freeze / hang whilst gaming

My handset (stock Vodafone) will hang/freeze when gaming. Sort of. If I enable in-game sounds, it's almost guaranteed that within a few minutes, the display will freeze. Game music continues to play.
The handset is still somewhat responsive, though if I hold the home button to bring up task manager, it can take between a couple of seconds and 10+ seconds for the window to display.
When I manage to get through to task manager, the game task shows 80%+ CPU usage. I'm able to kill the task and the handset is usable again.
This happens in every game and I've seen comments against certain games on the app store mentioning hangs/freezing/crashing on the SGS2.
If I disable sounds, the problem never occurs. I can even enable in-game music, just not sound effects.
I'm left wondering if there is a common handset fault, a software/OS fault, if maybe I just have a singularly faulty unit or if it's a whole lot of game developers using some common sound handling code that doesn't play well with the SGS2.
Has anyone else experience of this? I've tried Googling and I have tried searching this forum, to no avail.
Thanks.
You should post the names of the games you are playing. I didn't encounter any game that should freeze or hang because of sound.
Yes i too have been having this problem, and like you said, if you turn off sound in game, the game works fine. I have google'd it and a game developer has said that it may have something to do with the S2 sound system causing instabilities.
Some games which are notorious for me is robo defence and guns n glory, cut the rope also freezes when i turn the taps in the game.
Again turning off sound does allow game to be playable, but who wants to play games with no sounds. Trying to get on the phone with samsung if they know anything about it. Is anybody else having these problems 2? or can someone test playing these games.
I'm also having the same problem.. Coincidentally I also bought my handset from Vodafone.
Could this be related to Vodafone only firmware? :/
SGS II Freezing
My Galaxy S2 freezes when i play the game Cut the rope. the music remains playing. when i checked the RAM usage the game was using upto 55% ram.
This seems to be an issue with SoundPool on dual-core devices. Google is aware of the issue : http://code.google.com/p/android/issues/detail?id=17623
As the offending API has been identified, I believe we can expect to see a patch soon. Vote on the issue to help prioritize it.
galaxy s2 freeze
I've been havin the same problem with a game called fly boy and sometimes on google earth. google maps navigation and lattitude are fine and all other games are fine so far. I've noticed my cpu jumps about a lot even in stand by/idle mode. any ideas?

Plants VS Zombies fix for Galaxy Player 4 & 5

If your having trouble running Plants vs zombies on your Samsung Galaxy Player 4.0 or 5.0
(my game played fine until the night levels)
The game would lag, freeze, and touch controls would stop working.
then download chainfire 3d (Root Required!)
Open the "Per app settings"
and scroll to "Plants vs. Zombies"
now click the check box next to: "reduce texture quality"
You can also use "disable map buffer emu" but it's not as important.
The game should now run super smooth!!
how ever since we reduced the quality, the sprites of the zombies do not look as good.
But at least it plays
I have attached some in game screenshots take a look
-----
Note:
The fourth screen shot is blurry because it was taken while the game is playing, so NO, it dose not look that bad,
but it should give you a general idea of how the colors will look.
thanks! will try this if I also encounter the same problems in the night levels
I have the SGP 5.0 yp-g70 and it had trouble at first without chainfire and no overclocking. Then i oced to 1.2 GHz and it works fine. I havent used chainfire extensively but i find that it isnt needed for most apps except GTA III and maybe other gameloft games like modern combat (on GTA i still get lag but there is a way to fix it)

urgent help

just purchased this phone 3 days ago to play my favorite game deadzone. now i'm playing it its lags like hell and crash after 2 mints of gameplay i cant even finish a single map. i'm thinking to sell this **** now my mood is really upset
and i dont know what is the main problem every game lagging too much trail extreme 3 , subway surfer little lag.
task manager showing high usage of memory but cant find the app which using it because there is no app running
It ran smooth on my phone (p-765 v10d non-roooted). Played couple of games online too, lag free. Go to app settings and try to find out which process is taking more ram. Make sure unnecessary apps don b running in background. If u wan more free ram u better get rooted, after rooting i have nearly 450mb ram free. This device can handle most hd games i have tried most, u can see videos on youtube too!! SO WHY DON U TRY RE-INSTALLING THE GAME?

alright now i have factory reset it and installed trial extreme 3 still lags in game when showing all map and in gameplay sudden lag while driver is moving if anyone facing this problem in this game pls tell
When this device can run high end games like modern combat 4, nfs mw smoothly, its highly unbelievable to see that u are getting lags, try to free ram then try running the games. If the problem still persists then its better u get it checked by LG care. 1gb ram, powervr sgx540, i read these specs are better than s2
ok now i have checked some other games but still games lag. before i was having galaxy R(tegra 2) device in that some games are not supported but still what i play it play so smoothly but now in l9 it seems like games are supported but not playable. do i have to root it to get some more free ram ? will it help me to play games more smoother ?
bro plz post a screenshot of running apps...... if u have any antivirus, thn tat may be a problem (anyway i have rooted my device)
Odp: urgent help
Try changing governor to hotplug. But it doesn't sound good.
Edit: I played Deadzone on ultra high and it was smooth.

FIX LAGS ON ANDROID for Top Eleven Manager

I haved same problems on my galaxy s2, s3, and now same problem with laging on xperia z.
Then i go to developer options and tick force gpu rendering. App is now flying and there is no any lag.
Please can developers fix this bug and make the game smooth ?
Regarding the lags
I guess its not the problem with the app.
At normal usage, there is very less work for graphics and so it never comes into play but when you are playing a graphic intensive game, it needs a lot of graphics and the phone cannot render the gpu.
So when you enable force gpu rendering, it allocates more graphics support and also reduces the lags.
You can try clearing RAM and Used applications before playing games and also switch off internet.
Switching off internet reduces the advertisements on apps by which you can reduce some lagging.
Hope it helps and it works.

Emulation Quality on MediaPad M5

On occasion I like to play emulators (e.g., NES.emu, Snes9x EX+, GBA.emu etc.) when I travel but, with the MediaPad M5 10.8, I have been experiencing issues in regards to frame drops (stuttering). If I enable 'Frame Skipping', the issue stops but the end result is jank.
I find this surprising as my prior tablet, the Tab S2 9.7, had a SD 652 CPU and could easily handle PPSSPP or ePSXe whereas the Kiron 960s with its Mali-G71 MP8 experiences hiccups on games like Super Mario Bros. It will run PPSSPP or ePSXe but again, like before, frame drops.
No other issues to report aside from this; video/sound playback are optimal (up to 1080P/24FPS/60FPS - but 1440P is a no go) and no overheating. Battery saver is off. I've toggled 'Smart Resolution' on and off without difference.
Has anyone else experienced something similar?

I love a bit of emulation me, so I'll have a go with PPSSPP tonight on my M5 8.4 SHT-W09. Any PSP games in particular that you've tried that cause you grief?
I haven't gamed heavily, but I recommend deleting Chrome and uninstalling updates to Android System Webview (or experiment with uninstalling updates to Chrome rather than getting rid of it). I saw general improvement from this - and some recommend this for smoother gaming on any Android device (Chrome, or Webview if Chrome is disabled, serves as a system process that is used by many apps, so glitchy or otherwise heavy updates cause issues system-wide).
If rooted you may be able to clock the gpu higher for specific apps. See this Mate 9 thread (Mate 9 shares the same cpu/gpu):
https://forum.xda-developers.com/mate-9/how-to/mate9-takes-advantage-1ghz-gpu-t3601524
additionally go for the display options
try disabling smart resolution, fiddling around with the dpi in the development settings etc. I don't really play games a lot but cytus 2 and hearthstone are fine. Ark was a mess though

While I don't play emulation games, I think that many apps are written for SD only. I had came across a number of apps that cannot be installed on this tablet without sideloading and suspect that the CPU is the reason. This could cause the problems you are experiencing?

Thanks to everyone who followed up. Most appreciated!
I've been working away at this for a couple days now.
I've been using 3C Toolbox Pro to freeze unnecessary applications (including the ones previously suggested), used various governors and CPU configurations (all cores overclocked, all cores online etc), enabled GPU rendering, utilized smart resolution, disabled animations, disabled battery saver, have all ROMs running off internal (not external storage) and disabled several more broadcast receivers. I went so far to reset the tablet back to stock firmware and the results were the same.
So I'm thinking it's either a hardware issue, an incompatibility with EMUI or an issue with Huawei's implementation of Oreo.
I've already started a return with the Vendor so if the issue continues with the replacement, we can rule out hardware failure.
