Help! Nexus 7 (2012) - Nexus 7 Q&A, Help & Troubleshooting

I've just updated my N7 2012 to Lollipop 5.1.1 via fastboot. Everything is Ok, it's not laggy anymore, but there is one big problem: it often gets hot as if some programs are running even though I don't touch it at all. Please can someone help? I don't want to go back to Kitkat!

Use Servicely.

If you have root, install Servicely... great app, will let apps run only when you touch them...
Also you can set a duration to freeze the apps once the screen is off.
+ You can disable services (be careful and don't disable system services)

Thanks for your advice. No, I haven't rooted it. It seems to take longer to be fully charged. Guess I have to give it some time since it's getting old.

[Q] Investigating really slow Nexus 7 2012

Hi,
My Nexus 7 2012 (very first batch) is quite often behaving really slowly. It is common for the settings screen to take 15-20 seconds to open. From the homescreen. With no running app.
Here is a video after I've reset everything to factory defaults, let it run and index things on its own for an hour and then manually upgrade a small app:
At other times, the speed is pretty decent for such a tablet. I just can't figure out why this difference. I've tried to check for wakelocks, tried a logcat and many other things. I can't make any sense from it.
Rebooting the tablet seems to have 50% chance of fixing the problem. So it's probably not a memory leak.
The tablet is rooted, on the latest build and I noticed that App Ops X survived the reset but no funky software is installed and the behaviour predates the installation of App Ops X. The network is not a problem here. The 2013 Nexus 7 of my wife works just fine and so does the Nexus 5 taking the above video.
How can I investigate this ? Is there an app that can run various reliable diagnostics to find out what kind of activity is causing trouble ? I tried to use logcat but the result is quite verbose and nothing rings a bell. I would really like to understand rather than just return it and wait or, worse, buy a new device.
Thanks.
Let me know if you find a solution my Nexus 7 has been really slow, Im rooted with CM11 M6 & KK GAPPS, TWRP 2.7.0.0 I dont know what happened to this tablet.

Mine too. Nexus 7 2012 16GB running PA 3.99 (JB4.3). PA Kernel and GAPPS, PA launcher or whatever one came with stock PA.
It takes upwards of 10 seconds to unlock frequently, even from a fresh boot, and without any security just a simple swipe unlock.
App drawer can take 10-15 seconds to open.
If I touch too much during these lag times I will often get a launcher not responding error.
I've about given up myself and am looking at other ROMs. Before I reflash though I may try a different kernel.
I'm downloading a few right now and I'll hopefully remember to report back my results.
Mine is suddenly unbearably slow too. It's a 2012 edition and I'm not rooted, running the stock software. I've tried clearing caches (app and system), doing a factory reset, flashing the factory image, but it just runs like a dog. When I switch it on it takes a few minutes to become responsive, and apps regularly say they will take upwards of 20 minutes to download updates - small apps too, about 3MB. The download issues are nothing to do with my wifi as the tablet is slow wherever I use it, and my Nexus 5 downloads the same things in a matter of seconds. Would love to know what I could do to fix my N7. I don't want to root it or flash a custom ROM - don't want to go down that route - I just want the great performance that I had from it before.
I was having the same issues described here as well after owning the tablet for awhile, and tried every custom ROM, kernel, and android version I could find for our device along the way, in the hopes of finding a solution.
The one thing that finally helped for me, was formatting the device to use F2FS file system format on all partitions. The initial setup is a bit tedious, as you will lose ALL data on the device, so first must back up everything, then restore it all once the device has been reformatted. But the payoff has been huge for both me and my wife.
Making this switch has made both of our tablets usable again, even enjoyable! It's well worth the effort put in to make the switch.
See this thread here http://forum.xda-developers.com/showthread.php?t=2678140, which has the modified recovery, files, and instructions needed to convert. It also helps to first make sure you can successfully use fastboot/ADB commands from your PC to the device, in case you get into any trouble along the way.
There's also an app now available for converting any rom to all-f2fs (prior to flashing), it's cheap and well worth the cost (about the price of a cup of coffee) https://play.google.com/store/apps/details?id=com.runnerway.converttof2fs&hl=en.

[Q] random reboots on my N10

Hi all,
for the last few days I keep having random reboots with my N10, as well as random lock-ups.
Started a few days after the 4.4.3 OTA update.
happens like this:
I'm trying to wake up my tablet with the power button but nothing happens so I have to reboot.
Or, I am just normally using my tablet ant it spontaneously reboots, without warning, and also without any kind of lockup before that.
What is really annoying is that after such a reboot the tablet is not actually usable: none of the normal autostart apps initialize properly;
flipboard doesnt refresh, calendar widget does not show any entries, mail widget does not show anything, etc etc etc.
I'm on stock 4.4.3, but rooted with SuperSU.
it did not start right after the 4.4.3 OTA, only a few days later (actually, i think on friday or saturday).
Is there a way to get into the system logs to see what is up?
...turn on auditing, maybe?
Any other suggestions that might help me? What kind of details do you need?
Hi,
It looks like someone got a possible solution. I didn't test because I don't face random reboots on my Nexus.

Hi,
It looks like the person in the other thread set it to always display on notification bar, nothing other than that... As I said I didn't test so I can't tell you how possible it is for working or anything, sorry. I just gave this solution for now, if it doesn't work then I'd have to think a bit further .

Q&A for [ROM][AOSP] Google Edition S4/ Pure Nexus Edition[SAFESTRAP] Oct 4th.14
Some developers prefer that questions remain separate from their main development thread to help keep things organized. Placing your question within this thread will increase its chances of being answered by a member of the community or by the developer. Thanks for understanding and for helping to keep XDA neat and tidy! :smile:
Thanks Joe! And a question.
First off, I want to thank Joe for all his hard work! Ever since I upgraded from the S3 to the S4 I have been missing CM for their lack of bloatware more than anything else. Found this just over a week ago, installed it and haven't looked back at TouchWiz ever since!!! Everything works great but I have a small issue I am hoping someone can help me with, I have tried using GravityBox and a separate Xposed module to have a different picture on the lock screen but all I ever get is a black background. If anyone has any ideas I would love to hear them. Thanks again Joe for all your hard work and I am sad to hear you will be moving on. Was hoping to see some of that Lollipop goodness but I understand that hobbies can only take so much of your time. Good luck with your S5 work!

Which rom are you using right now? I heard there's an issue with GB while on the gpe version. You might have to do a nandroid backup and try out pure nexus as others users reported GB working with no issue for them. And sometimes after applied a tweak, you must restart your phone to take affect.

How to Pure Nexus on SGH-1337M
Hello,
I have the SGH-I337M with bootloader I337MUMUAMDJ and with TWRP recovery, I'd like to install this Pure Nexus but I don't know what to chose when it comes to the modules.
Has anyone installed this or can anyone provide me some advice?
Thanks,
OMG I am LOVING the Pure Nexus rom on my S4!!!!! I just want to say that this was my first Android experience and was going to be my last until I stumbled upon xdadevelopers and this ROM a few days ago. I originally switched from an iPhone (which was hard enough) but when I got my brand new S4 I couldn't believe how slow and laggy it was, thanks to ATT apps and touchwiz, my phone with all these great specs could barely keep up with MMS messages and was lagging just scrolling thru my contact list!!??! :/
So anyways, I was ready to move back to the Apple side of the world before I decided to give this ROM a try and after installing the Pure Nexus rom all i can say is... WOW!!! I think i'm finally falling in love with this device 1.5 years later. This is exactly how the S4 should be stock from all carriers!! Pure, clean, fast and functional!! very impressed! Awesome work Joe!!

I believe I was in the wrong forums, I found GOOGLE EDITION 4.4.4 by Danvdh, Kryten2k35 & Ktoonsez and I believe it is meant for SGH-I337M so I'll give it a try.
Also, I did have one question, is there any work around yet for being able to connect this to a PC via USB and being able to transfer files? Again, I'm on ATT NC1 using the Pure Nexus Rom.
Any help would be appreciated, thanks!

No. Look into airdroid or the app in the OP. There will be no work around unless our bootloader gets unlocked, from what I understand it's a kernel problem and there's no real way to fix it without flashing a kernel

Airdroid is really good, thanks Rhymey!
I couldn't get Multi Mount SD-card lite to work though, even after checking off MTP fix... like it shows up in my file explorer as a drive but everytime I click it, it says "please insert disk"... not sure why?

Wifi difficulties on Google Play Edition ROMs for I337UCUFNI1
Hello, I followed the instructions for the SafeStrap installation of various Google Play Edition ROMs on my Samsung Galaxy S4, NI1 found here:
http://forum.xda-developers.com/showthread.php?p=53758259#post53758259
I successfully booted into working installations for all of them (Pure Nexus Edition, Google Edition for SafeStrap v1.1, & S4 Google Edition for SafeStrap. The phone could receive 4G LTE, but could not turn on Wifi. It became stuck on "Turning Wifi on..." & never progressed elsewhere. I performed all manner & combinations of hot reboots & full reboots, with no luck.
I also tried flashing different ATT modules.zip from NB1 & NC1, none of which changed anything.
In http://forum.xda-developers.com/galaxy-s4-att/development/rom-google-edition-s4-t2837239/post55466895#post55466895
I also saw that in addition to hot/soft reboots, trying go enter/exit airplane mode may also get wifi back up again. This too failed. I'm utterly confused how hot reboots & this airplane mode fix worked for so many others.
Anyone else had luck with fixing wifi?
Requesting advice/help. I just flashed this rom and have experienced two data drops already within 30 minutes of me using the rom. What should I do to fix this?
also...just tried to install chrome from the play store. When I open chrome my phone immediately vibrates 3 times very quickly, and says "unfortunately chrome has stopped". Ive tried clearing cache/data and uninstalling, neither worked. Did I forget to do something when I flashed this rom? other weird stuff has been happening like I rebooted my phone one time and the wifi wouldn't even turn on and I had to reboot again to get it working.
Every time you cold boot, you need to do a hot reboot to get wifi working.

[Q] Any way to get the N7 to a state where I don't want to throw it against the wall?

OK, I know this is a pretty old tablet but I'd at least like to be able to get a smooth browsing, email, and streaming experience out of it; I'm not looking to be able to play games or multitask on it.
I'm running the latest version of lollipop and the N7 is rooted. Experiencing frequent serious intermittent lags/crashes, I mean like 60+ seconds can pass before the screen responds, apps hang, and the device occasionally will reboot itself. Other times, the tablet runs smoothly. Was hoping that update to lollipop would resolve some of this but, if anything, it's gotten worse. I've tried the usual "fixes" of clearing the cache, forcing TRIM, closing apps manually, and even did a factory reset + cleared all caches and still the problem persists. The problem seems to occur more frequently when I run apps like the Chrome browser, which I now avoid using. Not really sure if there is a decent process documented on how to troubleshoot these types of issues to find the root cause but the tablet is presently very annoying to use at best.
What I'd like is either: a) getting some help in determining what the root cause of the issue is, or b) switching to a ROM that doesn't have these problems.
Any thoughts, suggestions, or pointers to an in-depth troubleshooting article/thread?
If you find a solution, let me know.. I've tried combos of lollipop and kernels, kit Kat and kernels.. f2fs etc.. I keep mine as a docked alarm clock and ereader for bed.. but even that takes forever.

I gave up and went back to 4.4.4. I can FINALLY use my tablet again...
It's the flash memory in them. It's just degraded over time. I went back to 4.4.4 and it was excellent for about a week. Then it turned useless again.
That guide posted above seems to be a placebo other than the animation's being turned off. The n7 is absolutely fine after a fresh wipe, or a factory reset. For a week... I went through the guide and the only things it had that would make a real difference was animation speeds. I'll see how it does in a week.

hi! I was having the same problem, my n7 was super laggy and sometimes rebooted itself. that was just after uprading to lollipop 5.0.2. it kinda solved after rooting, doing a factory reset and installing lollipop 5.1. I hope it helps!
4.4.4 stock with all-f2fs rom. M-kernel r69. Both can be found here on xda.
This is how I got mine running smoothly again, even after trying several lollipop roms including 5.1.
Sent from my Nexus 7 using XDA Free mobile app
CM12 is not doing any better, I hope 5.1 could make a difference.
Stock 5.1 + Franco kernel with /data and /cache formatted to f2fs works beautifully for me. No problems at all.
I had all the same problems (and more) you and other spoke about when (a structure that holds back water and sounds like Ham) Google hounded and hounded me to install LolliCrap 5.02 (I ignored 5.0, which somehow disappeared). I HATED my #1 Nexus 7 16GB v2012. I also have a #2 Nexus 7 32GB v2012 (running HAPPILY 4.4.4) which I am still ignoring for "ham" good reason to install 5.02, an I never will install it or the latest 5.1!!
I have been exploring reinstalling the stock 4.4.4, but first I want know how to turn OFF future Google OEM Android updates and stop the "ham" badgering that there is a "new update available. But in the mean time, want to make #1 N7 useful again, I bite the bullet, backed up everything and did a factory reset and reinstalled everything. Even though I still HATE LolliCrap, my #1 N7 16GB is running pretty snappy again though some apps absolutely DON'T LIKE LolliCrap OS and are hanging and hanging and slow and crash (lazy Devs that aren't fixing whatever is causing that with 5.x). Apps I've noticed that are horribly slow with 5.x are Outlook, Skype, Yahoo Mail, Weather Underground, Drop Box, others
So, do a full reset and reinstall after backing up your data. You're gonna lose everything anyway when you Root and Boot Unlock to install an older version of Android or a custom ROM.
Hope this helps.
Glad to see another post here on the very topic I'm looking for. I'm currently running stock 5.1, completely stock, and it's just as bad as 5.0 was. I've read up enough to realize the issue is a flaw with the device, but am going to try and devote an evening or 3 to making this thing work before I completely give up on it. My goal is a minimal, feature poor but reasonably fast device for browsing, email, and some specific apps (a game or 2 and the Harmony Remote app)
Below are the areas I'm looking at, if anyone has advice or tips on any of these I'd really appreciate it:
Custom Kernel- Franco or MKernel r69? Need to investigate
F2FS - This is probably the best shot
Custom ROM - May stay stock, but if anyone knows of a lean, limited feature bloat ROM let me know!
Lightweight Browser - Can we get the original "Browser" App to install? Other options?
Basic EMail Client - not sure about this one..
The moment I saw the thread title, I knew I was not alone on this.
I remember the behavior first started with 4.4.4 actually, refusing to turn the screen on sometimes etc. I tried CM12+f2fs+mkernel 69 and it went well for a few days, then stuff broke again. I first suspected it's a RAM issue because I have two users running, but it constantly has about 150-200MB free (counting the cached apps, 400+ otherwise).
I guess I'll try slimkat 4.4.4 + f2fs modification, hope it can get the tablet running again.

1. For some reason Franco never boot my tablet for me...I've been using mkernel r69 and that's working really well.
2. Yep, a must.
3. Tried several custom roms and came back to stock.
4. Opera
5. Stock email, the one can be downloaded via playstore?
Rastapop with Franco kernel runs great to me. Keeping this thing alive.

To remove the update questions you got to root the device and disable the SystemUpdateService service of Google Service Framework and Google Play Services applications (don't know, maybe only Play Service one is really required, but better block both of them).
To do that use this application http://play.google.com/store/apps/details?id=cn.wq.disableservice

In my experience best custom ROM is Resurrection Remix.. I tried all tilapia Lolllipop ones except AICP, which now I'm very curious to try.. but I flashed Paranoid Android 4.6 BETA 6 yesterday and I will not change it until Google releases 5.1 firmware for tilapia too and people say this build is finally smooth and nice (well, too much hope, I know.. Lollipop will never be smooth on Nexus 7 2012, I fear )
Sofar I'm about 24 hours in using SlimKat with F2F2 (followed this post here - http://forum.xda-developers.com/showthread.php?t=2678142) using "Browser" that it comes with, and so far just GMail. Initial findings are very positive, it's quite fast, but I'm sure that could change.
Next steps (thanks for the ideas all!):
Install Opera
There's actually an update to SlimKat, but i'm waiting to see how the tablet performs as is without touching anything
Install and configure EMail client from Play store
Kernel - looks like this version of SK already uses the M Kernel so should be good there
There is an updated, F2FS modified version of Slimkat in that thread around page 90 or something.
I'm using that at the moment and it's been fine I guess.
Word of warning: recents menu is bugged to secondary user acounts. Only shows apps if they have been also installed for the primary user.
Yeah, I'm going to give myself a week or so on this older build and make sure it's stable before doing that. Definitely some stuff I miss from Lollipop in this, but if this is enough to breath new life into the tablet.. I'm willing to accept that loss :good:

DOK2 Feedback Thread

Since DOK2 is new and there are several hopes from many of the new firmware, I figured it would be best to make a thread about it.
To those on DOK2 (Especially 100% stock, i.e. stock kernels), please post your feedback.
One of the main things to look for is directed at FingerPrint unlock users.
After enabling FingerPrint unlock does the phone randomly lock itself?
Does the FingerPrint crash / TouchWiz crashes?
(This should be apparent with in the first 24 hours of enabling the FingerPrint lock)
The next main thing to look for is just general issues after the phone being on for some time. This would indicate memory management issues and would show up after hours / days with out a restart.
Are you loving the new Firmware? Post about that too!
Your feedback is valuable so please take the time out to post your experiences with DOK2.
Thanks!
I'm loving the new firmware. The phone "feels" faster in switching between applications.
The fingerprint lock-screen bug is gone (for me). Memory management has improved drastically. The only thing that is the same is the battery life in power saving mode. The update is worth it for me, so I'm not as eager as I was before to get marshmallow as I was before.
Note: This phone has never been rooted
I got the update and noticed a few bugs here and there. I fully wiped twice and it resolved everything. It's smoother, faster, same battery life, keyboard and fingerprint bugs fixed. I really like it so far. It runs like it should. I'm a happy camper now.
I've never rooted, full stock.
Remember to go to options > storage and clear your cache after updating! From COG2 to DOK2 I have never had fingerprint unlock issues. If anything it seems more accurate and faster. There is more ram I fall between 1.7-1.8gb (instead of ~2gb) used when everything is cleared. There has been no random reboots since the update. There is no more weather widget re-sizing itself and black shadowed font while scrolling through home screens. My antutu score went from 52000 to 48000 though. I am 100% stock never been rooted.
I've heard tell that you can't downgrade your bootloader back to COG2 after installing DOK2 update. Any word on this? Even through Odin?
^Even if you can't, why would you want to? 5.1.1 is better in every way from 5.0.1

sub? I assume you mean usb.. Did you wipe/reset everything? Even though this is an official update dirty flashing is dirty flashing. Wiping is still a troubleshooting step.
Love it so far.
The one thing that I have noticed is that the task switching is much faster. When I used to press the button, it would take a few seconds to load, now it's pretty much instantaneous.
I tried turning on the fingerprint unlock, but I was still having too many swipes to get it to unlock, so I turned it back off.

When you register you finger do you swipe at different angles each pass?
That is a must. My fingerprint scanner (when not crashing) works flawlessly. I never have had a problem with swipes.

Yeah, I did that. I did it one time and then I did it a second time with different angles.
Can anyone address if their GPS accuracy has improved?

Data speeds are much improved with the update. The device is snappier also. I haven't noticed a difference in GPS - seems about the same as before the update. Haven't had time to gauge battery life fully but that also seems improved.
Over all a very well put together update. I'm pleased.
I haven't rooted yet and I'm not sure I want to take this update yet. How can I turn off the auto update feature? The phone is telling me it wants to download the update and the next time I connect to wifi it will. Is there any way to prevent this?
Thanks

WARNING if you update your tmobile note 4 from 4.4.4 or 5.0.1 to 5.1.1 lollipop then dont do it. problems are the phone download super slow even if your on the best internet connection or using your own data. and if you like 4.4.4 or 5.0.1 then you will not be able to downgrade back to them. its no way to downgrade at all. im trying to sale mine on craigslist and get another one now
So weird, I installed it yesterday, rooted, and loaded a ported version of Kyubi's ROM. It's an awesome ROM, but too laggy on n910t. Reinstalled DOK2, and I canNOT root it again via Odin 10.7 or 10.3. It loads, and then goes into a boot loop. I've tried like, 5 times. Kinda sucks

I just learned this recently, so I guess it's my turn to pass this information to others.
You need custom kernel to be able to root. Flash BeastMode Kernel by @freeza.
