N7 stuck/won't wake up - Nexus 7 Q&A, Help & Troubleshooting

Hey guys,
I did some searching around the web regarding the issue with my N7 and couldn't find anything, so my apologizes if this has been asked before.
The issue I am having is, when my N7 has been sleeping for a while, (on or off charger) it will get "stuck". It won't wake up when I push the power button (or at least the screen won't illuminate). I can hard reset it by holding power+volup+voldown but that gets kinda irritating when I just want to quickly use it and put it away.
It doesn't appear to be causing a battery drain, it's almost like it's a sleep and just won't wake up. I am currently using CNA 3.6.6 with the latest franco kernel. I do not have a case at the moment (it's in the mail). I will be attempting a different ROM tonight to see if it retains the problem.
I have a Galaxy Nexus and sometimes it will fail to accept touch input, but the power/volume buttons have always still worked.
Any ideas?
EDIT: Can't find the delete button, but found a similar posting here: http://forum.xda-developers.com/showthread.php?p=32819135#post32819135

Try disabling auto-brightness and see if that stops the problem recurring.

Thanks
I saw that in the previous post, it appears to have worked. Any idea if there is as fix in the works?

wake up/sleep button acting up?

So, I've noticed that after the update the sleep/wake button has been acting up. I've found that sometimes you need to press it twice in order for it to register. Also then, sometimes after it would wake then fall back asleep within seconds of pressing the button. Anybody else experiencing this?
ztm
Yes! I might be able to second this. Thought I was imagining it.
Not yet able to reproduce it on demand.
I can recreate this and it's driving me nuts. But it wasn't due to the update. It's been happening for a few weeks now.
The power button to wake up the phone has been glitchy since the beginning for me. And the fact that the power button doesn't have good feedback when pressed, gives it some ambiguity whether you really pressed it.
I too am suddenly experiencing problems with the power key, everything works normally except now it no longer responds to a quick push to put it into standby. Long push still works. It was working fine after the update, it just happened suddenly.
You can use Keyguard Disabler, and it will allow you to wake the phone from virtually any "hardware" button.
One other issue is that it disables the lock screen completely, which some people feel is not a solution.
Maybe if you emailed the developer you could request that it not disable the lock screen yet still wake the phone from any hardware button, which I think is what we all want.
Anyway, I have to give it a thumbs up as a temporary, albeit not perfect and very unsecure, solution.
I don't have your problem, but as a former iphone user, I'm used to the home button to wake up the phone.
I'm having all kinds of problems since the update. This is one of them.
I agree with you.. for some reason. My battery drains like a mothafuga now. Today for exampe.
, I went to work at ten. Went to break two hours later and the battery was at 82% from 98%.. just sitting there idling.. why??
I also experienced this and also sometimes it wont wake up at all. It registers no input. I have to pull the battery and restart the phone.
I'm getting this, discussed it briefly elsewhere in this forum..
It's got gradually worse over the last few days for me. If you're still in your 14 days I'd ring now to get a replacement. I'm going to have to send mine off and be without it for a week.. Harsh.
Looks like it might be a fairly widespread hardware issue.
^Let us know how the fix goes. I'm not having an issue with it...yet! It's amazing HTC only made 2 hardware buttons and still couldn't have better than 50% success rate
its weird now... the button is acting fine.. dont send it in...... give it a couple days because mine did it a whole ton and then its gone. if you're really partial to your nexi, i'd just keep it... things will probably shape up
How odd, I've kind of discovered if I hold down the left hand side of the power button quite hard with my nail and rock it accross it works OK. Will wait it out like you said and see.
Sleep Button Un Responsive
Im also have the same problems where my Power Button is starting to not respong. I have to pres it like 5 to 10 times before it actually wake up or does anything. Even wile the phone is off like if I pull out the battery. When I put the battery back in, I have to press the button like 7 times before the phone responds and power up the phone.
Any suggestions or solutions?
Will HTC fix this problem for free with an unlocked bootloader?
nope unfortunately i learned that the hard way... $55
>>I agree with you.. for some reason. My battery drains like a mothafuga now. Today for exampe., I went to work at ten. Went to break two hours later and the battery was at 82% from 98%.. just sitting there idling.. why??
----------
Most of you know this but maybe it helps some.
You have to manage it a bit. Turn Bluetooth/Wifi/3G/GPS/AutoSync off when not needed..
Speaking of which.. does anyone know of a smart App that lets you toggle between programmable profiles for the above list of settings?
Also discharge/recharge the battery completely every once in a while. Makes sense to have an extra USB cable @ work as well.

Screen wont come on after Sleep

Hey guys. Phone's been good for a long time. Ran cm6 and CM7 nightlys for a long time.. Tonight is real first big issue
WTH.. I already tried Wiping, and nandroiding.
Now booting with old builds, and new build #33 when the screen goes to sleep after initial boot. I can't get it back on no matter what. Needs a battery pull first. Odd.. I'm hoping something isn't wrong with my nexus one. It's really acting up now.. Basically the phone turns on and runs, but the minute it falls asleep it's done for. I can wake it with my Power button, but only the soft capacitive key's light up. No screen. but I can turn the screen/key's off and on with no problems with the button. Just the screen never comes on. but I can watch those softkey's do it. So the power button is working, but it could be going out. but seems to work every time.
I've officially wiped tonight. I tried a nandroid to a past build, I'm thinking I might have a hardware issue.
Any idea's. Screen wont come on after falling asleep. At all, requires a battery pull. (saw this in CM forum) guy said fix permissions fixed it. any idea's?
This might be happening because of the WiFi/BT connectivity bug. If you watch the logcat (or maybe it was in kmesg), you'll probably see lots of errors regarding mmc0.
On the other hand, anything that would get the CPU stuck at 100% throughtput, might do the same, and it might be some other bug.
Try to turn off WiFi and BT and do the same, see if it helps any.
Neither are enabled.. Now it is doing this For sure, completely everytime. I can pull battery and boot phone. Seems to run ok, can open apps. go to market. whatever. but when I go into settings I get Activity FC and it freaks out. I just tried to power off my phone. It's been at the Shutting Down spinning circle part for over 15 minutes. Is it possible the build it 512mb went bad and thats why it can't resume from standby, and stuff?
I'm still testing things. but I've completely wiped and had no luck. and also nandroided to a good working version also. Basically if my phone goes to sleep at all. I can't turn it back on. I have to pull battery.
Same thing here..
Screen will not wakeup from sleep unless I do a battery pull... Any updates?
Its been 1 year since nobody posted, anybody came up with an explanation/solution?
This Issue just appeared in my phone after two years of use.
-When the screen goes to sleep it won't be possible to switch it on again. Either via the power button, time up or proximity sensor.
-The phone and the touchscreen work as always, haptic feedback reveals my unlock slider is still active and the phone can recieve calls and notifications.
-Plugging in the phone or using another button won't revive the screen either.
-The backlight of the screen turns on, but the screen remains black.
-Only removing the battery and waiting at least 10 seconds before putting it in again will let the screen to come back.
-Shouldn't be a software problem as i have wiped several times everything that could be wiped and instaled diffrent Roms, even tested ICS.
-In my case, removing the microSD doesn't change anything.
-Swapping batteries also doesn't help.
Anybody out there with the same problem?

My N1 developed this issue just a few days ago- I'm looking for a solution as well. I have all of the symptoms you've described, apart from the backlight turning on as I have an AMOLED display. It's interesting to know that the backlight turns on, as it and the video signal are controlled separately (and impossible to distinguish on an AMOLED display).
I've reverted mine back to an official shipping ROM, something really ancient, and it still occurs.
Mine is also right around the 2 year mark. There are a handful of other threads on various forums which describe the same issue with the only resolution being sent in for servicing. I don't know whether it was the screen or the motherboard that was replaced, which would be very helpful to root causing the issue.
I'm not sure whether it's an issue with initializing the screen itself as it is is functional and can turn on after a battery pull/sitting for a few hours. I would guess it's something to do with a capacitor or similar, since the way to get the screen to work is a battery pull +time or to wait a long time before turning the screen back on.
It's a shame, too, because everything else is working just fine in my N1 and I think it is the perfect combination of a phone.

Format your SD-Card. It's known to fix it.
Thanks for your suggestion, but unfortunately it does not fix my issue.
I've tried different SD cards, repartitioned & formatted the card (previously had a sd-ext partition), and even running it without an SD card- all either won't turn the screen on during boot (starting with the battery out) or will fail to wake the screen.
My logs don't show the mmc0 errors which would indicate an issue with the card; it seems to be pretty normal for the screen turning on and off, just that the screen doesn't actually initialize and display anything.
About a week before the screen wake issue developed, I had a problem with the camera and gallery thinking that the SD card was not present. I eventually wiped and reloaded an older ROM and the problem went away.
I replaced the AMOLED screen and it now properly works. Since the screen was able to turn on by itself after an hour or so, I suspect it might be a capacitor or something that's gone bad on the flex cable itself. I'm not sure how much effort I'll spend tracing it down, but I might at least give it a shot.
Change the Screen
Had same issue with a Nexus 5. I changed the screen and it worked great.

Did you install any applications from the market? Is your phone freezing while a certain application is open or does it freeze even on the homescreen? If you have a lot of applications installed try to deinstall and look if it becomes better. If not try a factory reset. If it still freezes than return it for a new one.
Would you mind saying what you were doing when it locks up?
If it's during Music, it doesn't actually lock up, it just shows a black screen for about half a minute. Everything still functions, it just doesn't show.
Two times trying to answer a call the screen would not unlock nothing would work I had to take the battery out and just todayit was sitting on my desk and it would not turn on when I tried to use it
The green message light was on very dim and I had to take the battery out

I have a feeling there is a bad batch of units out there.
Try factory reset and see if it continues to lock up, if it does, return it for another.

Sounds like a broken phone. Try a factory reset (if you return it they anyway ask if you did that) and if that won't help get a new one....

Same thing happened to me yesterday, the light was very dim green and the phone did not respond until I pulled the battery. It hasn't happened again.
I've already had to replace my Atrix for another issue. Right now my confidence in this phone is not very high, but it is brand new. Lots of issues will probably pop up and be fixed via software updates- at least I hope thats the case.
It really feels like all the issues people are having with this phone are software related. Maybe motorolla will just cave and give us gingerbread with no blur
I've had the same problem while playing music...over the past 3 days after about 30 minutes of tunes it'll lock up and after another 5 reset itself...i've done the reset after the second and it still does it...i'm bout to take it back and exchange it...i expect glitches but damn.
Motorola Atrix (stock)
AT&T Fuze (Energy.RAPHAEL.21916.Sense2.5.Cookie.2.0.sencity)
I have had the issue happen 2 me twice in 3 days, the last time was when adding the note widget to screen. It was not completely locked up just the touch screen, i could press the power off button but the touch screen would not let me shutdown
something you might want to try if a factory reset doesn't work would be a reinstall from the recovery menu.
power your phone off
hold the down volume key and the power button
release the power button once the phone begins to boot
keep holding the down volume button until you see "fastboot" at the top of the screen
now be careful, the down volume button navigates through the boot options and the up volume selects one
so press the down volume button until you come across "android recovery"
once you see it press the up volume button to select it
once you get to the screen with the exclamation mark tap the bottom right of the touchscreen, this should pop up the recovery menu
select wipe data/factory reset
let the phone do it's thing
good luck
I've seen this resolve some audio codec issues that were causing the phone's mic to not work, dunno if it'll work for your issue but it can't hurt to try.
best of luck

I have found a fix for my lockup issue. If the screen is on and lockup (no touch screen) press the power button 2, turns off the display and turns it back on and everything continues to work fine.

I have the same problem (screen randomly locks up once or twice a day, buttons dead) and have found the above "solution" to work perfectly, also. The problem however is that pressing the power button twice and unlocking the phone is not exactly elegant especially if the screen locks while you are trying to answer an incoming call.
I changed my battery settings to "performance mode" as I read somewhere that that might help. I will let you know if that seems to resolve the issue.
Changing battery setting doesn't seem to do anything. I still get my share of frozen/locked up screens a few times a day. Still have not figured out how to replicate the behavior. It really does seem random.
I've been suffering from this as well, I'm going to try to exchange my phone and see if that helps.
Exchanged my phone today. So far I haven't seen any locked/frozen screen issues. I am relieved. Maybe there are just a few bad units out there.
Also for what it is worth ... the lady at AT&T told me that taking out the battery while the phone is on would fix it. Since I never figured out how to replicate the behavior I couldn't verify that her suggestion would indeed actually fix the problem and demanded an exchange anyways.
atrix does lock up and have glitches
lock up glitch:
While in standby (screen black), it locks up. You obviously don't know when exactly it happens as it's lying around in standby. When you press the powerbutton to wake it up, nothing happens. You can try what you want, long press, several presses, just dead phone. As if the battery losts juice, but 2 times it happened and the battery was above 50%.
Tired to connect the charger while in that lock-up state. Nothing happens The notification light remains black as well.
The 2nd time this happened to me, I had the idea to call myself and see if just the powerbutton has a glitch and the phone is actually running just remaining in standby with a black screen. But nope, the phone didn't ring or wake up.
Only way to recover is to take the battery out.
I didn't mess with my phone and was very careful in which apps I installed. The only ones I have are very populoar 4+star apps:
extended controls
easy profiles
the other apps are most of the time not even running:
photoaf, vignette, imdb, nytimes, fb, skype, pandora, screen filter, droid light, prozoom5x camera
No games at all installed...
The 2nd glitch that happened to me a couple of times is that the finger print sensor is not working: It doesn't display any message as in " did not verify, too short, ..." it's just dead, the only way to get in is to punch in the number code.
This is typically fixed after switching the phone off fully.
Of course skype also doesn't work on my atrix (well known mic issue)
It happened to me as well. I had installed some apps but when it froze it had been off (the screen that is) so it was sitting then when I tried to open it by pressing the power button the green light came on but it would not wake. I removed the battery, replaced it then it did the same thing again (including the green light). I removed and installed the battery once more then it was fine. It must have been something in the backround but not sure as to what that was. Hasnt happened again though.

strange, skype worked for me... oh well.
did you ever find a solution for the lockup issue, have the same thing, very frustrating but not as frequent as you thankfully.
My Atrix started to freeze up when I undervolted the CPU using SetCPU and I would have to pull the battery out and restart it. I increased the voltage settings and it hasn't locked up since, so if you have undervolted your CPU and your phone is locking up, you should increase the voltages.

[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.

[Q] Stock 4.2.2 - Impossible to wake up, white flashing led

Hi,
Does anyone else have the same problem I have?
If I leave the phone running on battery for a couple of hours it is sometime impossible to wake it up by pressing the power button. Also the LED flashes white (not red). In order to get it working again I have to hold the power button a couple of seconds causing it to reset.
This happens on stock 4.2.1 and also in CM (4.2.1 and 4.2.2).
Seems like a HW problem? Should I send it in for repair?

I've had this issue as well. It may be an issue with one of your downloaded apps. I have gone back to stock without any 3rd party apps and I haven't had the issue yet. Going to test a couple days and see what happens.
Edit: Maybe if you post some of your 3rd party apps you downloaded we can see if we have some in common.
Sure, here are some of my 3rd party apps
Moxier Mail
Eniro
Hitta
Wifi Analyzer
CPU Spy
Subnet calculator
Quadrant
Dropbox
Facebook
Whatsapp
Viber
Spotify
Shazam
MX Player
Truecaller
Llama
Android Lost
Out of those, Facebook and Android Lost are the only ones we had in common. I'll report back on this thread if this issue returns on my freshly flashed stock device without any 3rd party apps.
Similar problem here...

Similarly, on two occasions now, I've gone to bed with the N4 on the charger, only to find it completely shutdown in the morning, and the battery unchanged from where it was when I plugged it into the charger. It required holding the power button down for quite awhile before I got a response and the unit rebooted. The first time, I didn't bother doing anything at all, but this morning, when it happened again, I called N4 support. I was advised to do a factory reset, and monitor it. If it did it again, they'll do an RMA. It seemed they would have sent another one right then if that's what I wanted them to do, but I told them I'd try the factory reset. They also sent an email with a direct contact link to the agent I spoke with in the event I need to return it.
My Device:
Nexus 4 16GB
Android 4.2.1
Kernel 3.4.0-perf-ge039dcb
Not rooted
I'll also post if the factory reset works. I've also read online, that holding the Volume Down and Power Button both for about 10 seconds, disregarding anything that appears on your screen, will shut your device down. Restart and, at least for several posters, the problem disappeared. Just an FYI. I'll try it if the reset doesn't provide the cure.
No joy....

It required holding the power button down for quite awhile before I got a response and the unit rebooted. The first time, I didn't bother doing anything at all, but this morning, when it happened again, I called N4 support. I was advised to do a factory reset, and monitor it. If it did it again, they'll do an RMA. It seemed they would have sent another one right then if that's what I wanted them to do, but I told them I'd try the factory reset. They also sent an email with a direct contact link to the agent I spoke with in the event I need to return it.
My Device:
Nexus 4 16GB
Android 4.2.1
Kernel 3.4.0-perf-ge039dcb
Not rooted
I'll also post if the factory reset works. I've also read online, that holding the Volume Down and Power Button both for about 10 seconds, disregarding anything that appears on your screen, will shut your device down. Restart and, at least for several posters, the problem disappeared. Just an FYI. I'll try it if the reset doesn't provide the cure.

Following up on my post yesterday, a hard reset did not help anything. Neither did an update to 4.2.2 for that matter. I also tried holding the Volume Down and Power Button until it shut down, and while the problem hasn't re-occurred, I really haven't provided enough time to tell yet. So Google is sending me another one and issuing an RMA. In the interim, while I'm waiting for the new one to arrive, I'll follow up if the VolDown and Power button has done anything.
I'm having the same issue. I just woke up, phone had a flashing white LED and would not boot. A reboot was neccessary. Is this a hardware failure?
The last couple of days I have not had WLAN activated. So far it is running fine.
I will activate WLAN today to see if the problem reappears.

Why would you think there's a correlation between the two? I do have problems with wireless-notifications; for example, messages on whatsapp are often delayed, where I get a notification at say 11PM when the message was sent 10:45PM. Do you also experience this?
No problem noted this morning...

I don't know whether holding the Vol Down and Power Button resolved the issue, but at least it didn't happen last night whereas it has been failing nightly when on the charger. Unfortunately, I was just notified that my replacement has already shipped, or I would tell them to hold off a day or two. For those of you experiencing this, you might try holding the Vol Down and Power Button at the same time until the device shuts down ignoring anything on the screen. Then simply restarting. I'm not saying that mine is fixed, only that it had a good night and that was the only thing I've done.
I will post again up until I have sent this device back. I have 21 days in which to return it or my credit card will be charged for real.

Mine also failed while on the charger a few times, but it also happened when not charging, so.... I'll try your solution. Why not!
This just happened again this morning. My alarm failed to go off, but the phone LED was flashing white. I could not turn the screen on. I did install some 3rd party apps yesterday:
Facebook
Tasks Free
reddit sync
Ally
IMDb
Pandora
Twitter
I tried the Vol Down + Power and that didn't work for me. I think I am going to RMA the device.
Yea...I have a few apps on my device, but not the ones mentioned here. So I don't think that can cause it. Hoping for more responses! I subscribed to this thread now.
Does anyone know if there is a bug report for this issue?
Not sure, don't think so as I've googled this quite alot. I just saw my telephone, which was idle next to me for about an hour, reboot itself. I saw the google and then the nexus logo without me even touching it. No white flashing LED this time, allthough that also has happened to me. This is getting very annoying now...
Google Support's reply on this
I have seen this happen to my phone more than a few times. I can't make it happen consistently though. I contacted the support hoping for a RMA, and today I received this response from them.
"Thank you for contacting us about your Nexus 4 and providing those details for clarification. This issue could be possibly not be a problem, it is a feature as with any Jellybean OS device; and goes in to the sleep state after some hours of inactivity - such as the details your describe when left overnight. It can go in to a deep sleep, where holding the power button for 30 seconds or more is what wakes the device up."
So this is a *feature*? It seems puzzling to me. I don't know if receiving a call would wake it up (if not, it would definitely be a problem).
I also tried different roms, PA and Xylon, and stock 4.22 with different kernels ranging from Franco to Motley. It would still happen. Rarely but it's still there. Also I am trying to see if changning the minimum clock speed to 1024 would change anything. I will report back once I have more info.
Still working so far...
I've not had a problem with mine since the Vol Down and Power Button shutdown. It may not even be related and may have just "healed" itself, or the problem has simply become intermittent and hasn't repeated itself yet...dunno unfortunately. Since my replacement will be arriving today, I may never know since I'll be shipping this one back to them. I may wait until Monday to ship it though, and see if it acts up again and repost if it does or doesn't.
Hopefully the replacement won't have this problem at all!
locked up
I don't think the flashing white-LED is a signifier of a problem. I think it is a different status message, like email or facebook, or something. I haven't found that documented anywhere, but I've noticed it is blue sometimes and white other times. Without being locked up.
My phone will lock up while charging overnight. I have turned off Dream State and the LED notifier thinking it was related to these. It did seem to be somewhat better after that, but the last two nights have seen the phone locked up.
Also, holding down the power button for 30 seconds will hard power it off at 10 seconds, it seems to me. That is typically how I deal with this lock up! Hold down the power button 10 seconds, release, press it again and wait for it to boot.
This is frustrating. I was thinking of rooting the phone so I can use a logwatcher, but I'm not sure I will see anything in the logs after booting the fracking thing.
But.. while I consider that I will start by uninstalling Facebook, Dropbox, and Twitter apps, based on seeing them on other people's lists.
I'm going to RMA the phone. Just a question, what charger do you guys use? I've been using a samsung charger (from my Galaxy S2), perhaps that's related? As it does happen while charging mostly, allthough I saw the phone reboot itself out of nowhere without it being plugged in yesterday too.
I've only used the Nexus 4 charger on mine. No others. I'm on my new device now but haven't sent the other one back yet. Probably tomorrow.
