Tutorial: How to find out soruce of Nexus 9 problems - Nexus 9 General

Very often i see posts "my Nexus 9 is garbage, its slow/random reboots/unresponsive etc." but theres such posts too "im lucky mine works perfect". Whats the difference? I don't believe thats wide spread hardware defect because theres no rule. Different Production Dates don't make difference, it doesn't matter if tablet was bought 2014 or 2015, or colour. My idea is that something is going corrupt app, data or system. Or bad application. Mine was sudennly saw behaving strangely slow, self reboots without errors 4-5 times a day, high pitch unpleasant noises from speakers when watching Youtube. I tell you how i fixed it.
Trough "Settings - About Tablet - Send feedback about this device" i looked into various system logs. There was lots of errors. I downloaded Device Assistant from Google. After it detected that my device rebooted itself couple of times it recommended trying out "Safe Mode" on Nexus 9 for 3-5 days to see if this app or hardware problem. I tried it for 5 days, guess what no more reboots all problems gone, my Nexus 9 self resets, high noises when watching YouTube, unresponsiveness, lag! It's gone its over week without problems
Safe mode disable all non-google third party apps from running, background apps from running too. It's like safe mode on Windows, only necessary apps are to use YouTube, Gmail, Chrome. If problems gone (lag, resetting) then do factory reset without backup, do not restore any apps! install app manually from Play Store not from backup or trough setup wizard. Try to detect what app causes problems trough selective instalation/system or event logs. It helped mine Nexus 9
How to turn on "Safe Made"
Press and hold power button
pres and hold "power off" option with your finger till pop up comes "Reboot to Safe Mode"
then choose OK
Idk if theres was something corrupted trough updates or bad app in background but its worth checking whats is soruce of problem

Search doesn't work on Nexus 7?

I've had my nexus 7 for about 5 days now since receiving it from the Google Play store. Aside from an occasional screen flicker I have absolutely no problems with it. Except...
Whenever I try to do a Google search through my Nexus 7, I find that I cannot click the links. The results for my query appear just fine, I can scroll through the results and switch from Search to Images, News, and what have you, but actually pressing the results does nothing. It's clear that it is registering my taps because if I hold my finger down long enough, it selects the text under it. Occasionally if I spastically tap the screen, Google chrome opens up and something actually happens.
Potentially unrelated, but my Tablet gets a little warm after continuous use. Not sure if that means anything or is out of the ordinary at all.
My girlfriend has the same tablet and this does not happen on hers, and through my searches I've not found any solution to this.
Any ideas? I would think that this is some kind of hardware bug except I have no issues in any application except this one.
edit: Also, I've done a factory reset of my tablet and compared the google search app version that my girlfriend and I are using. We are using the exact same version, 2.0.0.402395
Somehow, search is working properly for the first time since I owned the tablet. Since doing a factory reset didn't work, I thought I would try recovery mode. I turned the tablet off, pressed the power button and the down key, and selected recovery mode from the options. After waiting for my device to boot up, Search now mysteriously works without having done anything else. I hope this helps someone... somehow.

[Q] Some apps have started closing immediately on opening

Earlier today, a few apps on my Nexus 7 have just started closing within one or two seconds of opening them.
Google Search Bar, Facebook and Catch Note all close within a couple of seconds after opening them. I have used them fairly frequently for the last few weeks with no problems. Other apps, such as Twitter, Chrome and some games all work fine.
I have turned my device on and off a couple of times, but the problem still persists. Any ideas?
The problem is still occurring for me.
Gmail, Calendar etc... all also closing within a second or two of opening. Is this a common problem?
Is your N7 all stock or do you have a custom rom?...custom kernel?
You really need to provide some information in order to get help.
I haven't seen it in the OP so: Reinstall them

I haven't rooted my Nexus, or anything like that, it's all stock.
I just uninstalled Facebook, then downloaded it again. It seems to be working. Other apps still have the same problem. I assume that I have to do the same for all other apps - but is that even possible for apps such as Gmail, Calendar and the Search Bar?
Uninstalling and re-downloading hasn't worked as I had hoped.
It seems to have worked for Facebook. But I did the same for Catch Notes, and although it worked for a minute or so when setting it up, after creating a test note, it force-closed, I opened the app up again, and the old problem of closing within 2 seconds happened.
Other apps such as Gmail, I uninstalled, 'updated' again, and nothing changed, still closes immediately. There is no error message, it just returns to the home screen.
I thought that Task Killer might have been a problem, but I uninstalled that, restarted the Nexus, and the problem persists. Actually, when I turned off my Nexus, and tried to turn it back on, it was stuck on the 'coloured X' screen for a few minutes, I had to hold the power button down, and turn it on again. I'm starting to worry about my Nexus now.
Update:
A couple of other odd ones.
Google Drive doesn't even open. When clicking on the icon, the normal shading effect happens, but nothing else, no window even for a second.
Google Calendar opens, and just has a white screen, as if it is ready to load the calendar, but nothing loads. It doesn't close, just remains on the white screen, which can't be backed out of without pressing the home button.
Have you tried doing a cold-boot on the device? Maybe another app running in the background is causing conflicts. Where there any recent apps that you've downloaded?

I have just followed the instructions for a 'cold-boot' and now my Nexus can't get beyond the 'X' screen...
I have held the power button down a number of times, and tried turning it on again - but the 'X' continues to be displayed for over 20 minutes.
Just managed to turn my device on - but the problem still exists.
I didn't download any new apps that seem to have caused this problem. Though I think an app might have force closed and the Nexus displayed an error message such as "android/Google system stopped working" (probably different) and my home screen went blank for a while. Everything reappeared though after a short while. It could have stemmed from that.
Sorry about another bump, but i'm wondering if anybody has any more ideas before I go for a factory reset?
Edit: Actually, I think that I have found the cause of the problem. I just opened a game (Let's Golf 3) that I was playing before the problem started and after a few seconds, a message popped up saying "Unfortunately, Launcher has stopped". When I press OK, it returns after a few seconds.
I pressed the sleep button, and my Nexus turned off. Now trying to turn it on again, having some problems getting past the 'X' screen again. If I finally get in, should I uninstall the game? Any other solutions to this problem?
If your N7 can boot up, go the isolate & identify routines - disable/uninstall or freeze the golf game - do a normal shutdown/restart.
If normal functionality is back, you've just found the source. Not a gamer myself except for Angry Birds ... , but from the Play Store description, it access & make changes to system & protocol, etc. as you should contact/email golf's tech support for resolution. Otherwise, take a look of any background running apps or widgets, newly added or updated.

Thanks for the help.
I couldn't get my N7 to boot up, so I finally gave in and did a hard reset (by holding power + volume down, Recovery Mode, then wipe data etc...) but my N7 still won't boot up
I have wiped it twice, and rebooted it, yet it is constantly stuck on the 'X' screen. What on earth can I do?

You will need to download the factory image, unlock your bootloader, and flash it. There is a guide on this forum, it might be stickied.

I was hoping there was going to be a resolution to this other than a "flash to stock" suggestion... My Nexus started doing this exact same thing this past Sunday when it ran out of power completely and needed to be recharged. After it powered back up from charging the following apps quit working altogether or just started quitting once it appears they try to access data: Netflix, Currents, Zillow, Gmail, HBO Go, Press (though Google RSS Reader works), NVision, TegraZone and a couple others. I have done the reboot thing as well and almost had this thing brick again (stuck at X), but I managed to clear the data cache from the fastboot menu and it started up again. I'm now at the point where I'm troubleshooting individual apps but the clear data/cache, uninstall - reinstall process isn't working for any of the broken apps. This is now the 4th time I will be facing a 'flash to stock' situation as it appears that I've had every problem that leads to this 'fix'. I'll try a couple more things (mostly deleting and clearing everything) but I'm really frustrated with how many times I've had to flash this damn thing. sigh.

intermittent serious UI-feedback lag

Most of the time, my Note 7 is instantly responsive no matter how heavily loaded it is.
Every few hours, though, it gets into a mode with serious UI-feedback lag. In this mode, when I tap any key or icon, the corresponding click-and-vibration feedback is delayed by up to one or two seconds. Often I can type several characters with no feedback, followed a second later by a rapid-fire sequence of the delayed clicks and vibrations.
When the phone is in lag mode, the lag occurs in all apps and with both keyboards I've tried (Samsung and Google). And it's not just during typing; tapping on any icon produces the same lag. Lag mode is not fixed by closing all apps, turning on Airplane mode, clearing the clipboard, switching to a different keyboard app, or clearing the keyboard cache or data. (Clearing the clipboard did seem to fix the problem on one occasion, but not subsequently.)
Rebooting the phone does fix the problem--until it comes back again a few hours later. I've tried booting into recovery and clearing the system cache, but the problem still comes back in a few hours. I have not had time to try a factory reset. But the phone is completely stock (APH1), no power-saving turned on, no debloating or esoteric settings or apps.
As I said above, most of the time the phone doesn't have this problem, no matter how many apps are running. And when the lag occurs, the phone is not hot and is not draining the battery. So it's not a matter of the phone being overloaded; rather, it's a specific bug in the UI feedback.
The problem arises at seemingly random times. I have not noticed any pattern as to what triggers it.
Here's a video demonstrating the problem, both for typing and for icon-tapping:
https://vid.me/iYya
And just for contrast, here's a video of the phone when it's working properly, with no UI-feedback delay:
https://vid.me/GF82
Again, when the phone is in lag-mode, it lags in all apps, for typing and for all icon-taps, etc. The videos show only one particular app for illustration.

Yes this pretty much seems to be happening across Note7...hope Samsung fixes this

I exactly have the same issue u clearly described above. My phone lags intermittently and no matter what I do, it doesn't go away. After some time, magically it comes back to normal.
Not sure how to fix this.. very frustrating!

Same thing for me as well. I've heard whispers it's an AT&T thing. Been trying to fix by turning off Battery Optimizer for certain apps and using package disabled. I've noticed it's most consistently caused by locking and unlocking again within a specific time window. Like if you're using the phone, then you put it to sleep, and come back within about 10 min, it does it's lag mode.
If anyone who's having this specific UI-lag problem tries a factory reset, please report whether or not the problem comes back after that.
I did the factory reset multiple times but it didn't solve the lag issue..

After the factory reset, did you restore using backups (e.g., smart switch, directly transferring SD card) or did you set up as a new phone. I was having very bad lag. I used Smart Switch the first time. After a factory reset and rebuilding from scratch (without Smart Switch) my lag problem is gone. There is some discussion of this over at Android Central.

Thanks. That's disappointing but important to know, both diagnostically and also to save everyone else the effort of duplicating the attempt.
I'd be very curious to see if an unlocked (no AT&T bloat) N7 has the same issue on AT&T. If I get a N7, I'm hoping to wait until unlocked versions become available.
I have the same problem. It's the only thing I don't like about the phone. Hopefully they will update it soon.
All samsung phones has that. A new custom rom will fix it.
Same problem, sprint... Stock, TouchWiz. Switched to nova and it doesn't seem to have helped much.
I'm finding the problem may be gone. It hasn't shown up in the last 48 hours (compared to several times a day up until then).
There's nothing I'm aware of doing differently now, other than having turned off Report Diagnostic Info in Settings|General Management. I'm skeptical that that has anything to do with the reversal (but not quite skeptical enough to try turning it back on just yet).
Perhaps the improvement is due to an app update, or perhaps it's a delayed effect of clearing the system cache (though the problem did crop up once or twice after the cache-clearing, before it stopped occurring). Has anyone else seen the problem go away?
UPDATE: The feedback-lag returned after about 60 hours. Again, no obvious trigger. Very annoying.
Hi guys,
I am having similar issues. Most of the times the UI is pretty smooth, but intermittently it starts lagging, opening apps takes 1-2 secs and scrolling the pages isnt smooth, its very annoying esp considering the device is barely few days old. Need some fix to this, or its a dead investment!

Wait, are you talking about the same feedback problem that this thread is about? Taking a second to load an app isn't necessarily unreasonable. But a one-second lag for haptic feedback defeats the whole purpose of the feedback and is clearly a bug.

What i mean is that the lag isnt just restricted to feedback, the phone seems to stutter overall, scrolling on pages and apps is jittery. And this is noticeable since when it doesn't occur the phone is buttery smooth! I tried the google now launcher and it still persists. Turning the animations to 0.5x didnt help either.
Oh ok. Yeah, I'm using the Google Now launcher too. For me, the lag problem disappeared about 58 hours ago though. Just out of curiosity, do you have Report Diagnostic Info enabled in Settings|General Management?
UPDATE: The lag came back after about 60 hours.
Just for completeness, I should mention that after the phone went into lag mode, I also tried turning haptic/audio feedback off and then back on. But the lag did not stop.

[Q] Reboot issues

Like the title says I have an essential ph1 that constantly is rebooting itself I'm guessing it's a soft reboot because the screen gets bright freezes up and then boots to the lock screen does all this within 5 seconds but it treats the phone as it's been rebooted it's happening multiple times a day. Anyone else had this issue? I'm running Android pie. I have insurance but I'm afraid to make a claim because I've heard that the phone is out of stock everywhere and the value that they will give me is like $240 I like the phone.

Are you on a ROM? Kernel?
I ran into this issue with my OG Pixel. I found out the issue was I disabled some google apps. I re-enabled them all and the reboots stopped. Make sure Google Drive, Google Movies, Google Music, etc are not disabled.

Android 11 weird momentary popups

Hi folks,
I let my phone (6T, international version, completely stock never rooted), update to Android 11 this morning.
One thing is bugging me so far: at random times, I'll get brief flashes of some other window popping up momentarily (too fast for me to see what it is), and then it goes away. But it throws games into pause mode and takes me out of the flow.
What's causing this and how do I turn it off?
Welll this is not a normal behavior, so noone know why and how. Seems android 11 is not yet stable for us. I rolled back to android 10 on my 6T mclaren
Progress update: this problem seems to have resolved itself. I think it may have had to do with each app gradually settling in. A few reboots and some hours later the phone seems stable, though I'm having a few smaller issues like my phone icon left my home screen, I've now got TWO "Contacts" apps, and other minor stuff.
More update... the popups are back. I think they happen frequently after a reboot then settle down over time. I will keep an eye on it and report back anything I find in case it helps others.
Partial solution: I filmed what was going on in slow motion and despite my hand being in the way I saw the popup said "Gallery kee" presumably "Gallery Keeps Closing" or something like that. I don't use the Gallery app so I disabled it in Settings\Apps. Let's see if the problem keeps up. Maybe other apps are also contributing, and I'll have to address them one by one.
After a full day and another reboot for unrelated reasons, I can confirm that disabling the Gallery app fixed the problem. Not a single popup since I disabled it. Since I never use Gallery, only Google Photos, for me it's no loss. Probably a cache wipe would have sufficed as well. I did a a full cache wipe today to address a Gmail issue, and at some point I'll re-enable Gallery and see if the problem recurs despite the cache wipe.
