What causes the occasional lag on the Nexus 7? With its fast cpu and ram it still seems to have more episodes of lag than I would expect.
Is Is there a utility that would let the user see which app or background process is responsible for the overloading? Some apps may not be worth having if they overload Android.
Or, since lag occurs after using the tablet for a while, is overheating the problem?
Something else?
Trying to understand. Thanks.
It's always hard to pinpoint what causes lag. You could run low on available ram then when something needs it, the system cleans up some older stuff, causing a delay in the action requested. It could happen while waiting for a minimum CPU freq to get to a smoother one. It can also depend on how the selected governor/scheduler are handling things. That's just to name a few.

Not only killed my battery while downloading the needed DLC.
On top of that, my phone was boiling to the touch! And, after all that hassle.....the game lags! Didn't expect bad performance at all
Alright, just to add...
For some ODD reason, the CPU usage on this phone spikes HARD It's usually bouncing around 40-70%, that would explain the stutter in some games. Now to figure out how to fix this problem...

I've noticed that this phone stutters randomly when switching from app to app sometimes. I notice it happen when I am playing music via Poweramp, and then switch to maps, n when it loads the map, the song stutters hardly. I dont mean it skips a beat or something, it actually breaks the song and make it sound mechanical for a second before resuming the song properly.
Now I don't know if it's the phone itself, an app installed (maybe ram manager?) or just the lack of available Ram on the phone that is causing this, but it's sad and worrying to see a dual core 1.5Ghz cpu stutter under a light load switch. Anybody notice that the free Ram left on this phone is generally alarmingly low, around 130MB left out of 783MB? What is eating up so much Ram on this phone? When I was on the Atrix, I generally still have 300-400MB left free to be used (I dont recall whether it actually has the full 1000MB available or also 783MB though) and I never experience stuttering.
Is this resolution really tasking the CPU? or is it because it has to render these apps to fit properly in the 720P resolution?
p.s. Another game that lags: Jelly Defense, when you have a lot of enemies flowing down the path, it starts getting choppy.
As I mentioned, I'm pretty sure it's the CPU spikes doing it. I have around 400mb free of ram also. I know Dungeon Defenders lags on the Galaxy Nexus as well, but I'm pretty sure it doesn't have as many problems. Then again, it was built on ICS
Grab Memory Booster Lite and you can monitor how much RAM is being used as well as the CPU % for each task
Is Dungeon Defenders working for everyone else? I can run it for about 30 seconds and then it just closes. No force close message or anything, it just freezes for a second or two and then disappears.

after a thorough freezing, go launcher shows me at ~580M free on a fresh reboot and usually running low 500M free mem at any time, running 510M free right this second. this is with RAM manager, which by my estimates accounts for 5% in that #

Do you experience any lags on Dungeon Defenders (if you have it)? Or do some of your games stutter like bmxant's?
Ever since I updated my phone to stock 4.0.4, it's not been the same buttery smooth Epic Touch that it used to be on Gingerbread. Sometimes the lags gets so bad that the phone would restart itself. I have done a reformat and things have been going smooth for about 2 months and it has started lagging again now. Right now I am running minimum 3rd party apps, and only limited to reputable ones such as Facebook and whatnot. The CPU Spy shows the phone is in deep sleep most of the time. Android OS still takes up about 90% of battery usage. I made sure nothing is hogging up the ram in task manager and clear memory 2-3 times a day. Yet, it still lags like crazy especially while typing or turning the screen off.
Can anyone chime in on what else could be causing this?

since you mention facebook what's your sync situation like? just a suggestion as I remember similar threads where constant syncing was causing issues... if android os is using that much battery something is amiss... its just a matter of figuring out what...

FB's refresh interval is set to 1 hour. Is that what you are referring to?

Welcome to ics. I get the same thing and have tried everything. Good news is they are pumping out new builds pretty quick to hopefully they are working out all the kinks.
Sent from my SPH-D710 using xda app-developers app
try a different rom.
I've been having issues with the GN2's performance while scrolling menus and playing games. Jetpack Joyride is the most noticeable, with it stuttering all throughout. This even happens with simple games like Scramble with Friends, making it more unresponsive than it should be. Plugging the phone into the wall seems to lessen the stuttering. It also appears that the longer the app is used it slightly lessens the stuttering.
Strangely, frame rates seem better while playing 3D intensive apps like Death Dome.
My Galaxy S2 did not have any of these problems throughout its entire life span, ever. It did everything buttery smooth, which is strange considering this phone is supposed to be more powerful. The stuttering isn't terrible, but it's definitely there, and I'm not exactly happy with it.
This occurs no matter how many idle programs are closed or what Launcher that is used. I've used TouchWiz, Launcher Pro, and Go Launcher.
Is anyone else having this problem? Is this something that can be fixed or should I return the phone for another?

Wow, hahaaa! Thanks a lot! That's silly to think that works. I felt like it was some sort of power related issue and was sooner going to overclock the CPU than suspect that option.
It didn't work immediately after disabling it, but once I restarted the phone everything was fine. THANKS AGAIN!!
Hello,
I am the owner of SGN since september.
I am really disappointed, because there seems to be a problem with 3D graphics performance: and to be precise with its FPS consistence. In some 3D excessive games (GTA in particular, but also Trials Xtreme 3, NFS:MW and other AAA titles) there seems to be a problem: there is a certain interval of time when a game works perfectly, and then for a few seconds it slows down WITHOUT A REASON and then plays good again. This seems to be particulary a problem in GTA games where the game slows down to a mere 4 FPS, and then continues to run flawlessly for 20-30 seconds, then slows down again for a few, and so on.
PLEASE help me xda, you are my only hope. Noone seems to have a clue on what can potentially cause this weird problem.
do you have force gpu rendering turned on? anything running in the background? what about facebook syncing?

First of all, thanks for Your response.
Yes, I did triet turning the force GPU thingy on. Doesn't seem to help.
I think background apps are not an issue since I tested my phone after formatting it and it was clean.
Facebook syncing? What do you mean?
If you use the Facebook app, it might constantly trying to sync. You said you had the same problem on a clean install though so I'm thinking that's not the problem
I bet that the cpu is at 70 C, and the Thermal Throttle enter in function.
I had the same problem with dead trigger (i found that it automaically set up the Tegra effect)

Thanks for the answer!
Yes, the phone do gets quite hot after a while actually!
So is this behaviour normal? And how should I fix this, if it is at all doable?

When the cpu reaches the thermal throttal temperature (about 70°C) it slows the cpu down so that it cools down. When it reaches the 70°C mark again the procedure repeats. So if you would turn thermal throttle off it shouldnt happen again I THINK. But I dont recommend doing that. Stay safe, keep your baby safe (gnex )

Well, I cant find these "power saving" options mentioned in a thread above. Can anyone help me to find them? Are they even present in SGN?
And how can I disable thermal throttling, just for the test?
And thanks for all the help so far!
Why is it happening? I have to restart my phone about twice a week to make sure it is useable, else keyboard just won't come out sometimes.
It happened on different 4.2 and 4.3 roms, it seems to be memory related, but I shouldn't be running out of memory right? I even tried fancy kernel to add a bit more, but it still happens
Is there a bettre place where I should post this?
Test: Try keeping your phone to bare minimum apps - just the ones the rom comes with. See if your keyboard becomes unresponsive/slowdown. If no, then the issue is not the rom/kernel but possibly your phone usage and app-install habits.
Sometimes the issue is with excessive apps/and or poor memory management to combat the issue. This can be remedied by kernels or limiting the amount of apps you are using.
