Salutations...
Nitty gritty...
I heard/read somewhere that once you reach 50% capacity of your storage that your Nexus 7 would have performance issues...I think I may have that issue...I've deleted what I could and and have freed up more than enough space to consider my table almost empty, but, I still have performance issues. I haven't been able to confirm the theory nor have found even an inkling of a thread to address it. I can't pinpoint any other reasons for my symptoms like a bad app or anything...I'm not rooted,
Symptoms include:
Very laggy to no response with touch...
Occasional freezing that requires power button holds reset...
Touchscreen acts as if a toddler was scribbling with a crayon(hard to describe) but without moving my touch point...
....
All this becomes very frustrating...any help would be very appreciated.

Just try deleting cache/dalvik cache and reboot.
I'm not rooted, how would I clear the dalvik cache?

My nexus one became laggy recently with slow response to key depressions when typing emails and texts, changing between apps. Wiped the device clean and started again and all is well again.
Have you experienced this behavior on your N1? And if so is there an app or a diagnostic tool that we tell me whats going on? As now i have to reconfig it. Thanks.

probably something you recently installed slowing it down.
Wish i knew what, as i've put everything back on now.

System Panel will show if there's a particular application that's using CPU... Is the phone getting warm often or staying warm? That's the obvious indication the CPU is spinning..
I don't recall it getting warm. Well it's better now. I'll check the processes running next time it starts being laggy. Thanks for the tips.

You mean it's turning itself on or it's rebooting on its own?

If I keep using it for like 30 minutes (hard use) it reboot... How can I do a factory reset? Maybe that fix it...
PS: I notice when reboot it get really hot! I don't know if that is part of the problem..

You said your phone shuts off after hard use, and you said it is really hot when it shuts down. This sounds like a hardware problem. When the processor gets too hot, the device kills power to protect it from frying. Almost every computer has a similar last-resort power-off feature to protect its hardware.
Now the real question: What is making the device overheat? Most likely this is a hardware problem, but there is a remote possibility that the problem could be a rouge app.
A factory reset will remove the apps you installed. If there is an app running an infinite loop in the background, a factory reset might fix the problem. (I remember you said you are running stock without root, so there are no firmware issues. The only possible software issues are with your apps.)
I am sorry to say that you might have a defective board.

But why start doing that after a month of using it? The only new I did was using the maps app for more than 4hours... A friend toll me to clear cache on map apps...

If the problem really is hardware, it was a defect that made it past quality control. It's the same reason why a new hard drive might fail after a week of usage--infant mortality. Infant mortality is quite rare, but it does happen nevertheless.
Fortunately, Google's replacement procedure is quite nice compared to most other companies. If Google sends you a replacement, you can keep your existing phone until the replacement arrives. This way, you are not left without a phone temporarily.
Update! Did a factory reset and root it and it's good now! Looks like an app was causing the rebooting... Thanks for the help!

I've been having random reboots ever since.....well, a long time ago. No matter what ROM, kernel, or android version, it still persists. It happens at least 5 times a day. Sometimes 10. It even does it when I have zero downloaded apps.
Now that I'm done complaining, I'd like some help solving this formidable problem. Has anyone experienced the same thing? What can I do to stop it? Etc.
This is with an 8gb WiFi.
Thanks

After a reboot, you can know what cause this reboot with "last_kmsg" log. Look here for how to get it : https://code.google.com/p/tegraowners-ics-rom/wiki/How_to_get_logs
OK I did that. I scrolled through the unending file and at the bottom it said, "no errors found". Does this mean it doesn't know what caused the reboot, or did I miss something?

My nexus 7 rebooted while typing out this reply....so frustrating that this just happens out of nowhere. At least five times a day for me too.
Can't be the rom...I've been on pa 3.0 for a while and it was stable before. I don't think it's the kernel because I've flashed the top 3 kernels and it fixes nothing.
I am thinking it's a rogue app because my nexus is also draining battery very quickly and something is causing non stop wake locks and keeping my device from sleeping. Now I have to hunt down this app out of my 100+ apps
Android can be very frustrating at times

Revert to pure stock and if the problem persists assume that you have a hardware defect. Hardware defects are not curable with software - they are cured by replacement of the hardware. ( BTW, If you ran your device for significant lengths of time at extreme OC levels, you might have caused the damage; but that is for you to decide)
Mine has rebooted once in three months - but I could reproduce the crash ( using Chrome Beta on a specific WebGL demo ). That is very different than a spontaneous crash though, so I guess I could say it has *never* happened to me - and I have used the tab extensively every day for those three months.
hi guys ive had my razr m for a while. absolutely love it but ive been having issues with it recently. i am currently on the BDH rom and have been for quite some time. i have some tweaks in place with pimp my rom also using apex launcher with barely anything on the homescreen. i have 548mb for apps, 6.15mb for pictures/videos, 20.00kb audio (but 16gb for sd music), 7.45mb for downloads and it says 1.21 gb available. battery used to be good but now i get 11 hours with BARELY any usage after a day of work. softkeys constantly lag when trying to go back on a page on the internet or anything of that nature...same with the home button softkey. keyboard is extremely laggy (using aosp) even just turning the screen on and off is extremely laggy. pretty much what im saying is everything i do is laggy even clicking apps. i constantly find myself using ram booster and cachemate every freaking 20 minutes and that makes it better for maybe 5 or 10 minutes then its back to the lag... any suggestions for improvement guys? appreciate the help.
Maybe an app running in the background hogging all of your RAM. Also do you have bdh in a ROM slot? I found that charging it over on the stock side helps with battery issues. After all stock slot is ultimately best.

Having only 1.2gb of free space might be the problem or at least be part of the problem. I remember having slow down issues on my nexus 7 when my storage was near full. So I would try freeing up some space on your internal storage to see if that helps.
Have you tried clearing cache?

Yes I have jco I said I use cache mate and thanks legend I just ended up freezing and deleting a bunch more stuff and threw on some more tweaks with pimp my ROM and its been good so far knock on wood

Today i want to work and put the device in a drawer. never touched it during the whole shift but one phone call. during a five hour period 30% of the battery was wasted. bbs showed audioout_2 wakelock took place for 5 hours. screen time was 30 minutes. I haven't kept any screen shots from bbs but i did capture on system battery usage.
what could have caused it?

STOCK EVERYTHING .
not even rooted or bootloader unlocked. An out of the box Nexus 4 16GB (301k),.
Perhaps there's a corrupted media file somewhere in the storage system.

I have no media files on my storage, all my music is via GOOGLE PLAY.
(the wakelock is not caused by google play because since I booted the phone I have not listened to any music)
There seems to be a fix for the problem, haven`t used it myself though. Link http://forum.xda-developers.com/showthread.php?t=2050252. Its a init.d script at boot and you need root.
I wish to avoid rooting my device. when I bought the nexus I wanted to have a vanilla Google experience.
Also I don't wanna void my warranty.

Not rooting a Nexus is like forbidding the Pope to pray But to each his own.
Yeah I know, I think I'll root if i hear reports that rooted devices can receive official google updates

I remember one time, I left a game without closing the game. 5 hours later my battery dipped and I tried to figure out why. I realized that the game was still running in the background and drained a good 30% of my battery because of the mediaserver. I know it was still actice cuz when I hit recent it picked up exactly where I left off with no lag jumping back into it.
I'm guessing the game isn't coded to freeze in the background when you leave it. I could be wrong, but this is one possibility I think.
I'm on PA, with the matrix kernel. The game is called PAD in case anyone wants more info. I say, just be sure to exit games or generally certain apps when you finish playing them.
This only happened once and since then never again since I started closing that particular app correctly. Also, I don't mess with any music volume booster mods. Just get some noise isolating earbuds/headphones. The volume booster mods definitely killed battery much quicker than it was worth with my first nexus 4
I close everything and still got 1.5h of AudioOut_2 and AudioOut_3 wakelock overnight . 20% battery drain overnight. normally my battery drains 5-6% overnight.

Maybe there is a corrupt file on your phone, it doesn't have to be music, could also be a ringtone or a video.
considering you don't want to root I would consider factory reset then reinstall 1 app at a time until you find the culprit. I know it's time consuming but it's either that or keep your charger handy
