[Q] Delay for screen wake - Nexus 7 Q&A, Help & Troubleshooting

Hi, one morning i woke up and my nexus 7 had a major delay when pressing the power button to turn the screen on. It is constantly taking 3-4 secs for it to wake. I have tried turning off currents but that has no effect, nor does a factory reset. Just so happens the first time it happened was after charging, i know there have been issues with charging bit not sure if this is the cause. Any help would be much appreciated.

I know it's a bit late to reply, but I just got my tab and after charging it to 100%, this started happening...
Hopefully now that I've uninstalled G+ and Currents (and rebooted), it'll stop...
Just erase any app you don't need (especially the stock ones) and see if that helps... I mostly blame Currents and GPlus...
I see that's on the 4.2.2 update, and it's also happening on custom ROMs based on it (PAC, CM, etc.)...

I encountered this too. screen rotate seems to be the culprit for mine

I sometimes encounter this also. But the thing that really annoys me is the slow auto-rotate. I decided to disable auto rotate and just turn it on when I need it. Accidentally, it seems to have also fixed this delay. It seems like the auto rotate is causing delay to the display of lockscreen since the lockscreen also rotates.

[TEST] touch screen/calibration issues... may have figured some things out?

Ok, so over the course of time I have owned my phone I think I may have found one of the reasons for the phone to go out of calibration in terms of touch accuracy but I just want to make sure its not just my phone doing it.
What I have noticed is that if I hold my phone at an awkward angle for a few minutes (typically 5ish minutes) the calibration will go out of whack. This notoriously happens when I have my phone in navigation mode and just laying on my lap (landscape mode). Today I was driving and I got a text mid way to where I was going so I picked the phone up to hit the talk-to-text button (which is really nice for texting while driving by the way) and it was out of calibration, could not hit the button to save my life. Similar has happened when I held the phone at an awkward angle while watching a movie laying in bed. So I would like to see if anyone gets similar results holding the phone at an awkward angle for a few minutes, I would say give it 5-10 minutes for an accurate result. Try doing things like holding it literally upside down while its in landscape mode and then switching it back to portrait and type on the small keyboard again. I would go into a program of some sort that you can test touching all areas of the screen with.
Now, it seems like before the OTA update, I would have to reset the phone and sometimes that wouldnt work still. However now (and I have tested multiple times with consistent results) that if you lock the phone and then unlock it, the calibration seems to be adjusted again.
Let me know your results.
**For the record, I have had a very positive experience with this phone since I purchased it but I have been able to replicate the "touch screen issue" many a times and would just like to get to the bottom of the issue if all else to just avoid it or tell others how to avoid it happening to them because it is quite annoying.
it sounds like a software hiccup i would hope it would be getting patched sometime..... but as of now i dont know of anyone that's got a fix for it. i have the problem from time to time but i just lock and unlock and its fine, kind of annoying but not something that makes me want to throw it out the window or anything.
Judging from the behavior, I'll place my bets on it being a software issue rather than hardware. There seems to be some hiccups between the accelerometer and the screen getting confused about angles/tilting.
didnt happen to me before upgrade. Its happened a couple of times since.
My phone had been on charge and I had changed to setting to disable it from sleeping while on charge. I had turned the screen off but it must have woke up I went to use it and couldnt hit any keys.
I thought it may be something to do with it being awake for a long time - but it could be coincidence.
I can confirm that putting the phone to sleep and waking it fixes the problem
I have the same issue. No problem before OTA and described problem after that. Grrr.
Mmm, I experienced the problem both before and after the OTA, so I dunno.
Good to know that you can just sleep the phone and then wake it back up to fix the issue now. You used to have to reboot.
I have not had the issue at all since removing live wallpapers. Maybe just a coincidence.
Do people using custom ROMS have these issues?
Ok, so there are similar results out there then and sounds like 100% confirmed just locking and relocking recalibrates the phone back into proper order, no more full reboot is needed.
For the record, I am not using a live wall paper, I have not rooted or installed any themes or anything so my phone is all stock besides the OTA update. Also, as someone else stated that you used to have to restart your phone before the update and I experienced the same thing but again now I only have to lock and unlock the phone for it to recalibrate.
Grainysand you and I seem to have had similar "issues" if you even want to call them that with before and after the OTA and I share your view that there is an issue between the accelerometer and the software recognition.
It's definitely the accelerometer. For the record, I've never had to either reboot or relock/unlock the screen to fix this. I hold the phone upright and it corrects itself, though sometimes it recurs.
I've noticed this a few times after the ota, but just turned it off/on to fix.

Same here. Usually when in landscape mode and the device is tipped at a 45 degree angle. I've also seen the N1 (when using the browser in landscape) scroll the page back and forth very quickly (about 1/4"). When this happen the device seems to get 'stuck' in landscape mode even when I flip it back to portrait.
After the ERE27 update, I've only really noticed the issue when I've plugged in the charger.

now that I think about it, I must say that most of the time I see this happening it has been on the charger... will test later though, i doubt this would effect the issue
I think it has something to do with live wallpapers, the ones that receive input touch to react in some way or another. Its a software issue.
You could put it to sleep and on wake up its ok.
Or you could touch the buttons slightly to the right.

no its not the live wall papers... I have tested both with and without live wall papers and I can produce identical results as far as loss of calibration
Not sure if its the same problem but when playing games sometimes, the isnput locks up sometimes when in landscape mode. However rotating the phone between landscape & portrait mode seems to fix the problem, might help for this too.

[Q] Nexus 7 screen turning itself on?

Hi all,
I'm experiencing an issue on my stock 4.1.1 Nexus 7. The screen seems to be turning itself on randomly. It normally turns off again but may toggle on/off quite a few times. Then it seems to go for a while whitout turning on. Bit odd.
Anyone else experienced this or have any thoughts on a reason for it?
Thanks
Same problem here, except with a Samsung Galaxy Nexus.
I just updated to 4.1.1 today and this is the first time I've seen it happen. Was previously on 4.02 without issues.
I have had the same problem. It seems to happen in the evening and I wondered whether the case was causing it to overheat. Seems to be OK when I take it out of the case. I phoned Google and was told that it hadn't happened before. I will contact them again if it doesn't get any better.
Sorry. Misread the post. Mine goes to sleep, not turns on

Same here but mine is not exactly stock.
I have installed Apex Launcher plus numerous apps. I thought maybe it was the launcher doing it. But at this point... I have no idea. Just noticed it tonight coming on and then going off within 1 sec. but its random. it may do it once within an hour, or it may do it up to 5 times within a min... then go several minutes completely black screen. Crazy stuff. I thought maybe it was getting a message at first but then realized I had the WiFi off on my phone so it was dead to any incoming messages/wifi. I am really curious as to what is causing it and will be following this post as well as others quite frequent. Also.... the latest app that I have downloaded was OSMOS HD. it wasn't waking then sleeping before that app... just my 2 cents.
Hi Qbensis,
By stock, I just mean not rooted and not running any custom firmware. I had various apps and the like installed.
I have actually since rooted my N7 and installed a few custom ROMs and since then have not seen the issue at all. If you want to stay stock, I assume the issue will be fixed in the next update
I have seen this a few times. Middle of the night I look over and the screen is on then off. I check the power usage overnight and I see little blips of screen on when looking at the graph. Not sure whats causing it (I figure a app).
Same Problem over here, any solutions???
I'm on stock 4.1.2 and having the same problem, not rooted. Creeped me out in the middle of the night when it goes on and off.
N7 Random Turn On
Same here on 4.2.1. I carry in front pocket all the time with screen facing leg and feel heat when it happens. Has even done it when in Power Off mode and still does it. I thought that would prevent it for sure. Very irritating and drains battery. We Winter in 55+ community and drive around in golf carts. I am starting to wonder if WiFi spots trigger it. Will continue to track behavior and search other forums. Curious that there have not been any solid suggestions or solutions.
Happens to my rooted but stock 4.2.1. It happens randomly when I recharge using a battery pack (4AA) as opposed to charging using regular AC. It's annoying as heck! I don't know how to get this fixed!
I've been getting this on both SmoothROM and raspbeanjelly, and it's very irritating.
It has to be an app that is causing this. I initially thought perhaps it was GPS Status, because I caught it in the notification bar a few times when the screen turned on.
My device definitely isn't hot when it happens.
I'm suspecting the Email app, Maps, or Facebook.
EDIT - not any of them either. I'll test Beautiful Widgets next.
Okay guys, try this.

I'd been suffering from this for weeks, factory reset, reinstalled and changed out ROMs, installed apps one by one over the course of several days to keep an eye on what might be triggering it etc. Nothing worked for more than 2-3 days at most, and the issue always came back in one way or another.
It was causing me to have to turn the Nexus off when not in use because it would be draining battery (15-20% overnight compared to 2-3% when the issue wasn't present).
Then I stumbled upon that guide and using Gemini I disabled Maps from auto-running, turned off Latitude, and so far so good.
If it works for you too, be sure to hit thanks on Karpfenhai's post!
I was having this same problem on my Nexus 7 running stock 4.2.2 rooted with SuperSU. Finally tracked it down to having installed BetterBatteryStats and for some reason, I had not granted it perpetual root. It was causing the device to wake and turn the display on for random times (up to 13 hours, which killed the battery), not always showing the SU request dialogue. I granted perpetual SU privilege to BetterBatteryStats and problem went away.
Try taking out the battery and clean out the USB port with a toothpick. This worked for me. All the dust that accumulates in the post can cause the phone to think it's charging.

Freezing and rebooting on lockscreen after screen rotate

Hi Guys,
I'm not sure if this is related to 4.4.2 or its a hardware issue, I've only noticed this issue this week.
When I wake my N10 and if I flip the screen around before unlocking it, it will hang and reboot.
It happens every time after putting the N10 to sleep for a few mins.
If I unlock it without rotating then flipping the screen around its fine.
Has anyone else had this issue? Anyway to fix it?
Hi
Just did it and it worked fine for me, I'm also running 4.4.2... You may want to try a factory reset before issuing this as a hardware problem

on the same boat
Same behavior exactly observed on my tablet, during last week. I suspect something went wrong with the newest updates.
Random crashes with reboots, mainly when rotating on lock screen. Tried a factory reset, however, problem still persists.
Never had a single problem with my Nexus until now, worked like a charm. Also, I have not installed new Apps which to blame for this problem.
At the moment I'm trying things like disabling rotation or pattern unlocking, will see if something works.
I think I've seen this as well, on KOT49H. Not sure exactly how to reproduce it, but it's happened a few times.
Do you have modded/unlocked system? My nex is working like never before. It is twice as smooth and stable as it was on 4.3
I have never rooted/moded this tab and never ever had issues with it...
tapped from my nex
Well, disabling rotation seems to improve the issue a little bit, the random reboots are still there, but just less frequent.
Yesterday I had a couple of hangs-reboots doing simple tasks, like checking GMAIL or interacting with Google Currents widget.
In my opinion, this is not a hardware problem, it is, somehow, related with the 4.4.2. KOT49H update. My N10 worked perfect until this last update.
Ironically, I read somewhere that this update fixes the random reboot problem in a lot of faulty tablets. In my particular case, the "fix" seems to trigger the issue in my tablet
It is worth mentioning that my system is not modded or unlocked.
Updating situation ...
During the last week I have used the N10 With the automatic rotation disabled, in landscape mode. Non a single reboot.
This afternoon I just enabled automatic rotation again and the tablet rebooted itself almost instantly, at the second orientation change.
So, IMHO, This issue is only rotation-based, nothing to do with the lockscreen. It is kind of annoying.
Any help?

Hi,
Do you mind sharing a logcat when it happens? It would help a lot to see what's causing the problem.

I never had this problem, but I just tried rotating twice before unlocking, and sure enough that does it.
There are still so many things that cause this device to reboot. I love the hardware, but god is it ever unstable
This is, I hope, my final update regarding this situation..
Well, It is kind of embarrassing to inform that the problem is, apparently, gone. I didnĀ“t do anything to solve it.
So, it looks like some app or widget was causing the instability, and it must be fixed now via a recent update. Honestly I have no clue about who the culprit was..
Thanks, anyway, for your comments and support, and happy new year
Same issue
So it seems I have the same issue too, except I have a Galaxy S4 Touchwiz 4.3. Anytime I go into landscape mode, boom it freezes and reboots. If I disable rotation, then it'll just keep randomly freezing throughout the day. Never happened before, everything was happy go lucky and then I don't know what happened. I reinstalled kernels, took off recent apps I may have installed, tried a different modem, nada... This is a pain. Anyone else with similar issues other than OP?

[Q] Black screen when quickly pushing lock

I'm having a bit of a weird issue with my new Verizon GS5.
Scenario: I am doing something such as reading a text, decide I'm done and lock the screen, and then a second or two later realize I forget to check something and hit the lock button again to turn it back on. Most of the time when I do this the physical buttons will light up but the screen will stay black, and a few seconds later the physical buttons will turn off. This will happen a few times until finally the screen turns on and I see the lock screen.
I had a similar issue with my Galaxy Nexus (rooted and running Kit Kat) phone prior to the GS5 and figured it was my old hardware- is this some Kit Kat bug?
Thanks for any input
Same issue here. But I can't figure out if it was due to switching to ART or not.
We can wait others reply with this i hope someone will post a tip on this kind of problem.
I switched to art after installing apps and I'm ha ing this issue didn't really play with phone much until after switching to ART. Is anyone having this issue not on ART?

Had this a time or two. It's like the power button doesn't register or something. Yes I switched to art.
I have found though that if I hold power for a second it pretty much fixes itself without having to do anything crazy like yanking the battery or restarting the phone.
Imo: not a big deal, doesn't seem to happen a lot for me.

I'm having the same issue for the past two days; although, I am not switching between apps or anything (only trying to use the phone). No display, but get sound/vibration from buttons and LED lights from soft keys. Unfortunately, both times required me to yank the battery. My S5 is completely stock (not using ART) and have manually reinstalled my apps from old device. Any suggestions?
I am not experiencing this and I have switched to ART...

I hope this isn't the case. Once again I experienced these EXACT same issues with my Galaxy Nexus running 4.4.2. I can't help but think it might be some app causing it since not everyone has it.
I am noticing this every once in a while. But it's mostly right after I shut the screen off after a large processed app or task, and then remember something I forgot to do and try and turn it back on and there is some lag bringing up the screen again.

I was about to return my S5 to Verizon for this very reason. I haven't switched to art and have been having the screen go black on me, you can tell the phone is on because the physical buttons are lit. It seems to happen to me alot when I take the phone off the charger and hit the on button. I will hear the phone rebooting, but not see the boot animation. Thats when I do a battery pull. Holding the button doesn't do it. I also have had a few random reboots. Thats ok...I'm going to try every root method under the sun..gggrrrr..lol
I've started to try to uninstall apps to see if I can narrow down the issue. It still plagues me at least half the time I try to use my phone.
This is happening to me as well. Not as often. I'd say once a day, but I have to pull my battery to restart it. I did 2 factory resets and am now using a new google account as per verizons request and I added apps slowly. I have been fine until I put a second launcher on. I installed the GEL launcher but did not use it just to see if having multiple launchers could cause this glitch. Could it be this? Is everyone else using a different launcher? Also the only time I ever had it happen while messing with the phone was two times while working in light flow. Any one else connected to those two happenings? Trying to narrow down what could be causing this.
Running ART here, I'm not sure if I'm getting this problem, but I have realized some latency from pressing either the home or power button and the screen turning on. Not sure what causes that lag, but it's a good almost full second whereas my S4 would be instant

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.

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.

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.

This lag seems to be AT&T specific

I did the factory reset multiple times but it didn't solve the lag issue.

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.
