CPU Usage - Samsung Epic 4G Touch

Anyone else have an issue where an app will freeze, and when you go into your task manager, it'll show it using up to 60% CPU? Only way I know how to fix it is exiting the app, and re-opening. Anything else I can do, or is it just a bug I have to live with ?

I had that problem a lot too when I was stock, not happening on viperom

Guess that gives me an excuse to root. I'll try it out.

Random 100% cpu usage. A.k.a. AGGRAVATING LAG!

About 3 times a day, my evo will start to lag horribly. I check system pannel and it says the cpu usage is 100%. Then i look at the processes and theres like 3 apps running and then the normal system processes. Anyone know why?

Which apps are running and maxing your CPU usage? All 3 or 1 of 3 could be the culprit? Apps like Watchdog can tell you what app is blowing up and you can take it from there. I've had a few get out of hand and killing once or uninstalling / reinstalling has corrected it. Clearing data / cache for the app might help. Gotta figure out which ones are maxing it first.
blah blah effin blah
Usually its my normal stuff like handcent, lookout, ane maybe music. Its like one minute its fine and the next its lagging like crazy.

try what conqu1stador said with the watchdog app and if you still cant figure it out, try a different kernel.
Yeah i got the lite version. It looks like a very very nice app. Thanks for your replys.

So it just happened again, finally. I looked at Watchdog right away to see what was causing it, and turns out it wasnt an app at all. Its "Android System". Now, to be honest, im not really sure what that means ( im guessing it means my rom or OS or something like that). Can anyone shed some light on what is happening?
If it matters im running myns 2.2 rls5, and kings #9 kernel.

I was having a similar problem, figured out it was the stock voicemail app, froze it with TB and problem went away.

More than likely you're having the dreaded wakelock issue caused by the combination of baseband 2.15.00.11.19 & PRI 1.90_003. Downgrade your PRI to 1.77_003. That should alleviate the wakelock and battery drainage. If you do not have this combination, download and install the aLogcat app. After initiating the app, look for and pay attention to anything colored in red.
Only time this happens to me is when my phone is syncing my accounts

Yes, but whenever a wakelock appears, Android system seem to always display a high percentage use.

Force closing

How do I find out which Android process is force closing? It happens every time I restart my phone. It doesn't happen too often but it happens at least once every time I restart. The notification does not say which process, it only says Android process. Sometimes my default keyboard, swiftkey x, is replaced by swype after force closing the Android process. Thanks in advance.
Edit: it actually says the application Android system force closes

That actually means "Android System" is force closing. I know useful right? I don't remember where to get the information that might help figure out why but typically a full wipe and a reflash will take care of it.

yea you may have deleted something thats acting up or maybe you installed something your phone is not happy with. I would try to do as the poster above said or run fix permissions in recovery or Rom Manager and see what happens
Are you on an EL13 build? What is your exact setup? If its EL, I may know why.

Yes I'm on calks 2.5, so I'm on el13. Also I don't mind reflashing and a wipe, but if there is an easier way, I would prefer to do that.

I do know that undervolting was causing a lot of people to have reboots including myself. I reduced it from 75 to 50. Also did you use Titanium Backup to restore data to your apps. That also causes some issues
I have neither manually undervolted my phone nor backed it up using titanium, so i dont think its from that

I was told that the Android System is calling a file that doesn't exist on EL13. Is it only when you power on phone? Strongsteve found it and fixed it on his ROM but I don't have the knowledge to locate it myself. Is 2.5 Calk's latest update? If he has a newer build, you may want to update. Maybe he found it and fixed it as well.

Since installing Calkulin's 2.6 and EL13, Google Maps has been force closing on me after reboots. I'll be watching this in case it's a related issue.

Freeze instead of force close

********UPDATE*********
Thanks to hardcore,I found a fix in another thread
forum.xda-developers.com/showthread.php?t=1843837&page=4
Using a terminal emulator or adb shell,
su
cd /data/log
chmod 444 dumpstate_*
This sets those files to read-only permissions and that seems to fix it.
Ever since Jellybean instead of apps force closing as they normally would my phone becomes unresponsive and reboots after 2-3 minutes.It gets quite annoying and I wanted to know has anyone else has been getting this issue. I have wiped dalvic/cache also factory data reset,I am unable to do anything in anycut,the phone automatically goes through freeze process,any ideas on how to fix issue?
got the issue too. Only on tw based roms tho. why i only **** wit cm10/aokp. And anycut doesnt work completely with jb yet. You have to use the anycut widget instead
Thanks for the response I guess the only way to stop the problem is not to have a tw Rom,I guess I might just have to bit the bullet on that one,im not really into flashing roms I'm only rooted for hotspot and system settings to change certain things

Could always setup the dualboot to have stock and an aosp rom
Okay I might have to look into that, thanks for the quick responses I thought I was the only one, my friends have s3 to add well and was not experiencing issue,I can see now that's for top them not having stock Rom

You could also find out what process is causing the bad behavior, what's not playing nice, and remove or freeze that app. You could also try to do a fresh install of your rom.
I was getting the same issues, but I found out that Maps social pin-point (Latitude) was causing my issues and unchecked all of the options related to check-ins and location sharing. No problems since.
When you say fresh install do you mean hard reset?if that's what you are referring to I have done that and wipes in recovery. And how exactly did you find it was that specific app doing That to your phone?

For that specific problem, it was trial and error, but a logcat would help. At the time, I couldn't figure it out. I believe there's an app to help read logcats.
Okay thanks

Any update? It still happens?
Sent from my SPH-L710 using xda premium
Did you use the app? It seems that the app triggers a force clse popup if (im guessing here) a certain amount of time has gone by (like the OS itself does, but maybe shorter) or whenever an app goes unresponsive (it comes up instantly)
So either way, its supposed to fix the force close dialog not showing up for you.
I have our installed but I guess im still working on how to use it, I'm going to try to run it in the background

Update!!!!! Thanks to http://forum.xda-developers.com/member.php?u=336619
Thanks for the tips guys. This was also irritating me to no end on several Samsung roms. I think it happens on the Note and S3 too. Maybe even the S2.
My solution was:
Using a terminal emulator or adb shell,
su
cd /data/log
chmod 444 dumpstate_*
This sets those files to read-only permissions and that seems to fix it.

Maps using all my battery, but i never use "Maps"

Like 30% of my battery for the third day in a row is Maps, yet I haven't opened maps once. I restart everyday and it happens again. I assume it has to be the gps, but i dont know of any app that is using it, either.
Touchdown uses about the same amount of battery, so I'm wondering if it has some gps feature running I don't know about? How do I figure out what the problem is?

try this, go to your app manager, locate your map(gps) etc.. and wipe cache.
If you turn off your location access i think it might help.
Using anything like Google now ?

Messaging app real slow

Sorry if this has been addressed before. I dont see the search option with my phone.
Everything that relates with the app is running real slow. I've cleared data and force closed it on top of restarting my phone. I'm stock. Jw if u guys might know what's up. Thanks

Might be your kernel and the settings you put in it. Try increasing your voltage by ~25 or increase the min MHz.
