[Q] Complete lockups of system. - Nexus 7 Q&A, Help & Troubleshooting

Hi all,
Info:
Running PA 2.99
Faux Kernel
No overclocks/undervolts etc.
For a while now, and I'm not sure when it started, but from my memory, pretty much after PA 2.54?
Whilst browsing the internet, especially watching vids etc, my tablet completely crashes, like the processor is struggling! But, they arent just normal lock ups, my tab completely locks up, and goes nuts !!
Even having like 3/4/5 tabs open completely destroys my tab.
Usually, I have to fully power-down and back up, for it to work again.
It happens on various browsers, such as Chrome, Maxthon and Dolphin.
Any one else experiencing serious crashes?
Any one know what could be causing it?
Thanks,
Wilks3y.

Details would be helpful. Which versions of 2.99 and faux kernel, for instance. As out stands, your question is about as vague as walking into a doctor's office, proclaiming ‘I'm sick‘ and not saying much of anything specific.

Revert to pure stock for a while.
If you continue to experience similar symptoms using stock then hardware is possibly implicated.
If not, then it's software (kernel or ROM or kernel tuning parameters).
On pure stock I can crash the kernel (using Chrome beta on certain WebGL demos), but largely Stock seems pretty well behaved on my tablet.

[Q] how many browser crashes do you get a day?

Howdy folks,
I've been running custom roms since I first got my iconia. Though I went thru a brief period of over clocking I am now running a stock-based rom.
Browser crashes every once in a while have almost become a fact of life but I am curious, are they also for you? How often do you experience one?
I am currently on FLEXREAPER RF1. In 3 hours I've crashed opera twice (once with flash) and the stock browser ounce.
In a typical day, perhaps 2-3x on stock browser is the norm for me.
I look forward to finding out if my iconia is messed up or if this is normal. Thanks for your input!

Define "crash". Getting Force Close errors? General Protection Fault? Or just the browser closes without warning?
I might get browser close a couple of times a day. No big deal. I get it on my pc also.
Browser crash ALOT for me usually becoming unresponsive while playing or using flash content.
Opera, stock, dolphin all the same.
chrome not so much but then again it doesnt play flash so i dont use so much.
Really annoys me alot to be honest not sure if its a ICS issue or not.
As for other crashes no not really just browser for me
Cheers
I used to have the browser close pretty frequently on me in gingerbread (stock os/stock browser). I have not noticed any since ics (also all stock)
Stock browser usually quits to homescreen suddenly. Sometimes it remember the site it was on sometimes not.
Opera crashed on particular site by exiting to home. It also froze up while playing episode on daily show website.
So far (haven't had it long) opera seems stable but a page here and there mess it up. Plus that flash issue. Will stick with it awhile longer to see if it does better on stability. What I mean is it's not random like stock.
Evelbug, how long do you use the tablet and how long have you been on stock? Been thinking of switching over to see if more stable.
Thanks!
Have only had RF1 on tab since yesterday but experienced quite a few browser crashes at least with stock browser, hangs for a second then just closes. No FC or other message.
XDA Premium app has been doing the same thing so not sure what's up with that.
I'm on flexreaver (12.5, I think), and haven't had trouble with the stock browser crashing. I get the occassional screen flicker and have to reset my wifi once in a while, but the browser seems well behaved.
quick update, in case anyone's browser shopping,
opera mobile all day today and no closes or crashes. a few sites it doesn't do well on, but I guess that's what the stock one will be for...
I have had it in the beginning (browser just closing) when I just install a rom but after a few days it is gone.

[Q] CM10.1 - Ready for Prime Time on the Nook Color (encore)?

I have a Nook color wiped with a full version of the last stable release of CM7. It works well, but with that irritating problem of wifi reliability.
I would like to upgrade to CM10.1. The goal is to use the Nook as a development platform, while still sharing it with my wife to actually read books.
Here is the questions: Is release candidate two (RC2) of Cyanogenmod 10.1 stable enough on the Nook for daily use? I want the latest and greatest, but I don't have the time to constantly be chasing down problems, nor do I want my wife to kill me because her "book reader" has become unstable.
Do I hold out for RC3, wait for a stable release, or jump right in with RC2?
All comments and suggestions are welcome.
While CM10/4.1 was promising, CM10.1/4.2 has been a pain.
The interface seems all weird (it use a Phone interface instead of Tablet), and the performance makes the Nook Color nearly unusable. I'm talking single-digit framerates and choppy scrolling.
Personally, I found PA to be smoothest I tried... surprisingly smooth for the NC.
YMMV
I don't know about the others, I lost WiFi connections once every 2-3 hours using the most recent builds including rc2.
The fix is just turning the eifi off and on again.
However I never got sod so it is acceptable for me.
Thanks for the info guys, but the question is still up in the air. What condition is CM10 in for the nook? The wifi issues in CM7 make it useless as a connected device anywhere except with my home router (go figure). Is anyone using CM10 as their daily driver, and if so what build are you using, and where would you place the frustration level on a scale from one to 10?

I'm using CM10.1, RC2, and I'm having only very minor issues that are probably due to the ancient hardware (Flipboard sometimes freezes on me after 10 minutes, and browsers are slow, except for the very light Naked Browser). Everything I need works great, including wifi. I took it on a three week business trip to South America recently and only used my laptop once, doing email every day with no hiccups. I think it helps to tweak some settings, and use the Seeder app. Scrolling isn't butter smooth, but it's very good. Frustration level close to 0. Go figure.
I used CM10.1 for few months, it worked very good. I would say my frustration level maybe 1, and pretty much nothing compared to the satisfaction. I liked the key board, wifi connection, HD video play (for example in youtube), Browser and new UI in CM10.1 over 7.2.
recently I upgraded to CM10.1 RC4. I also did the following things to make it better. after boot up, it still has close to 150 MB memory.
1. tablet UI by autopatcher.
2. V6 SuperCharger
3. ES Task Manager to disable some startup services like Email, Email Exchange and etc.
4. Seeder.
The result is very good. It runs very smooth.
Only frustration is the speaker's volume which is low. I am using Speaker Boost, looks like helped little ( but not very sure).

I find that it works for some apps, DSP Manager works for others.

I uploaded RC4's tabletUI patches, and you can get them in my signature link for My 4 Shared.
I tried one of the RC's back in the day for CM10 and didn't like it much. It seemed slow and glitchy, and it kept corrupting my SD card, so I went back to CM7 for a while, and then tried the CM10.1 nightly for 6-17 yesterday and had SD card problems again. Switching to a higher quality SD card fixed that problem, seems 4.x's file access methods make it more finicky with external media than 2.3's. According to LMT's status bar, my NC is running at 1000mhz, and everything has been fairly stable, although there are a few apps that seem to grind it to a halt, most notably the new Opera browser, although I hear that may just be an issue with their new version, using Opera classic seems to run fairly well. As far as getting the true tablet experience, I had to switch the launcher over to Apex, which has a tablet mode that removes the phone-style dock. On another note, I have two Android phones, an older one running CM7, and a new one running ICS out of the box, tried wireless tethering on each and found that my NC could Ad-hoc into the newer one and share it's internet at remarkable speeds, but couldn't maintain a connection to the CM7 phone even if I skipped DHCP and manually set the IP. I tried Bluetooth on this one and found that neither Sixaxis or Wiimotecontroller worked, but the NC did detect the Wiimote I tried, so I know Bluetooth is working. If I can find my BT headset, I'll give it a try and see if I can't make some internet phone calls. At this point, I'm going to be using CM10.1 as a daily driver, I think it's VERY usable, with my only annoyance being that it's a little slow to boot - any custom boot animations I use other than the one that comes with it are choppy and freeze up, and once the OS has loaded, I have to wait 10-20 seconds while the lock screen says (WIDGET LOADING) to even get the lock screen clock, but after that it's smooth sailing.
On the subject of reading books, I installed Moonreader+ and read some books on it yesterday, so that's still working just fine.

[Q] why the heck are my programs exiting?!

Okay, this is getting ridiculous and im getting pissed. My N10 has been working without a hitch (and without a camera flash too) for the past 6 or 7 months since i got it but one thing that is happening now is getting very annoying is it just exits out of apps when the app is trying to load something...not exiting when the app itself is loading, but when the app is busy loading another task. Man im getting mad...so for example im on facebook the interface loads fine but when i start browsing pictures and an image is taking a few seconds to load and BAM, the program closes, another example i have the AOSP browser opened and im browsing the web, I type in a web address it starts to load, and BAM, closes, playing candy crush, it plays fine and then i try to ask for help from facebook and once it starts loading my friends and it does it again.i could go on and on. its happening on game apps, google apps its pissing me the heck off and it just started about a month ago. I have tried several roms thinking it was a memory leak somewhere or something for that matter and no luck. Ive tried trinity and KT kernels thinking the stock kernel was the culprit and still no dice. Ive even gone as far as to wipe out the whole device, everything to the fullest system format and reinstall a new stock image via wugs toolkit...still happening. Can anyone tell me why this is happening and is there a fix for this? Is anyone going through this crap too? The Dev forums have been quite lately but im sure this tablet still has very active users who can help because this is getting old. BTW I am running Purity latest rom with Franco kernel r12 just in case you need to know
Does this happen after you watch videos? For me, that's the only time..apparently the surface flinger eats up the RAM and hardly 20-30MB is left for other apps. So I guess the system starts force closing the apps. I don't think we have a permanent fix for this yet. However, the workaround I have applied is I disabled Chrome which is another RAM eater and since then this random force closing and even the random restarts problem seems to have been alleviated!
Another simpler option is to restart the tab whenever you feel it is starting to operate with a lag. Takes hardly 30 seconds And hope for Google to release the fix to the surface flinger issue with 4.3!

[Q] Apps Close

Hey guys I've been having a major problem with most apps and games on N& running P.A.C. This problem plagued my device when I was running PA as well. The main issue rests with apps closing by itself after a few minutes,as if the device had run out of memory even on a fresh boot. For example I would be in the middle of note taking on Evernote and few minutes in it would just close. Same goes for YouTube and ALL games. Funny, Lightning Browser seems to be the only one that stays in memory. I'm running it on stock kernel Android as well so tracing the root cause has been difficult.
Any advice would be great since I'm in the end of my ropes!

Start by flashing stock and see if it still does it. If not, try a different rom. If it does it on stock....then you may have screen issues...like phantom touches of your home button?? Or something.
Try whatever the nexus 7's version of a log cat is and see what it says when it happens.

Help me to get rid of the lag

hello,
i'm getting crazy with this annoying micro stuttering and occasional lagging. it's happening everywhere - home screens, app drawer, settings, apps like xda and tapatalk. it's not major, but it's enough to be seen and to drive me nuts. i tried stock KK, Cloudy stock 2.5 and Cloudy G3. i also tried several kernels - stock, bruce Kernel and Dorimanx. i also tried tons of different settings for cpu governor and hotplugging; i tried the lag mod which have to remove the scrolling lag - it seams that nothing is helping. i tried with and without Greenify (to avoid a lot of resident apps), i also tried both Dalvik and Art - nothing. the slight lag is there - and it's just that - slight stutter, few frames dropped - enough to make you think that some setting will kill it finally. but no matter what i try, that slight lag and stutter is still there. can you give me some suggestions - i'm coming from Galaxy S3, which i used with Beanstalk rom - i experienced 0 lag and stutter and i cannot believe that i see that in a phone like the G2, given the powerful processor and the 2 gb of ram.
please help me not to get insane with that phone

I've only got 550mb of ram free and my phones flying. Not even a little bit of lag. But for the first week or so after re flashing the stock Rom I did get all that lag you were describing. Even after I debloated, flashed Bruce's and did every other mod you can think of. It ended up going away on it's own after a while. Maybe you just need to stick with one setup and let your phone settle.
You can use beanstalk on the g2 as well, if you were interested in going that route again.
I have the same issue. In games it lags and stutters just enough to put you off the game. I have noticed some videos do this as well like youtube. I am still testing this but I am reluctant to spend any time on it as it has a clear issue when other lower spec'd phones run the same games fine. Basic games as well. It is subtle, but the stutter is there. On some games it's can even be a full 1 or 2 second complete lag and game halt. I tried the CPU throttle option in hidden menus and this did nothing.
Can this be hardware problem? I phone LG and the support agent was extremely unhelpful. He said that it would be sent for repair and they will not play games, only flash it and run a test. I'm concerned this will be a classic case of "there was no fault found" and it will be a complete saga for ages. I already had this before with a different phone (different problem) and I'm fed up with phone problems.
Mine is from Vodafone UK store bought. I am tempted to try stock UK firmware to see if this fixes. Shouldn't have to though.... I also might end up trying a custom ROM to see if it goes away. I absolutely love the phone otherwise. I just want it to work.
PS: It runs benchmarks fine with high scores.
