[Q] Phone won't wake up/black screen - Nexus 4 Q&A, Help & Troubleshooting

Hey guys, been having an issue on my N4 since I installed lollipop. It seems that leaving bluetooth turned on is causing my phone to have the SOD or not wake up. Notification light will still flash, but screen won't turn on. The only thing to do is hold the power button down to force a reboot. I have seen this happen on my wife's N4 also so its not just my phone. I have left bluetooth off and the phone has stayed on for over a week. But after turing BT back on and using a bluetooth device (handsfree earpiece) with in a few hours this issue crops up.
I even restored my phone completely back to stock and am still seeing this issue. You can check the battery stats after the reboot and it shows it kills the cell modem, but the only thing that stays powered is the wifi, but the battery part of the screen shows like the phone is off.
I haven't tried leaving bluetooth on and having wifi off, but something is screwing it up. I was hoping the update to 5.0.1 would fix this since we got an updated kernel, but its still happening.
anyone else seeing this? surely I can't be the only one seeing it on my 2 phones.....

In fact I just experienced this this morning. The only difference is my phone appears to have locked up during the night and my alarm never went off which caused me to be late for work. I also don't have my Bluetooth on, only WiFi.

Random Shutdown

When my phone is sitting idle (screen off) it will randomly decide to power itself off. Has anyone else noticed this? Any ideas on what could be causing it?

you mean randomly power itself ON, right?
if that is the case, it's normal, it just mean it woke up to connect to the internet, to get updates of news, emails, or whatever it was scheduled to pick up
nope. i mean it randomly turns itself off. this topic is being discussed over on the att captivate galaxy forum section.
interesting, so it's going from stanby mode, to complete OFF... nope never seen that happen to my i9000 model
yep totally powered off... completely sucks... looks like there are a bunch of ppl that have this issue with the captivate on att. $10 says its some lame piece of software that att puts on your phone that's causing the problem.
it's possible, i've read here a few users having crazy power issues (battery draining very fast) with their SGS i9000, but after wiping it out clean, to start anew, then the power problem is gone away.
so yes, a software could cause something weird like that.
Factory reset and so far so good
Hey guys,
I use a Galaxy S here in Hong Kong and I had the same random shut down issue constantly happen when my screen went off...
I tried everything, check temperature of cpu, etc. etc. and nothing worked, it just got worse and worse.
I even changed the battery to use the spare one that came with this. Still problematic.
Used SET CPU to limit the cpu to 400mhz, still problems.
Finally I did a factory reset and so far so good.
I only have the original system installed with the Remember the Milk app installed.
24 hours, no problems.
Installed AppBrain app.
Then I installed 3G WatchDog
12 hours, no problem.
Then I installed Paperdroid
12 hours, so far no problems at all.
If I run into an issue I'll post it here. But I think it definitely was a software issue.
Update - it randomly shut down on me
Alright guys, it shut down on my randomly today in the afternoon......
I dont know if it's the re-charging that screwed it up?
Because after my factory reset, last night was the first time i charged it....
Hmmm
This happened to me too - two days in a row until noon it would shut down two or three times - i uninstalled SetCpu and for now (24 hours) it hasn't happened again. I am not sure if it was the one responsible but it started happening after i installed two programs and i uninstalled them after it started happening. I uninstalled Visual Task Switcher first but on the next day it turned off again, then i unsinstalled SetCpu and it hasn't happened again - maybe some wrong profile settings but i didn't feel like experimenting
I had this issue once too in about 40 days.
I was reading an sms and then i turned into standby and put it in my pocket. Later, maybe 40 minutes i came home and my phone was completely off. I do not remember if i had to take out the battery before to get it on again.
I was wondering why it happened. Maybe it was caused by an app i had opened. Battery still was at 40%.
But since it only occured once in 40 days i doesn´t bother me.
Interesting you mention this as it just happened to me today for the first time. I took it out of my pocket and wtf? The phone was off. Very strange... Using the i9000 on the stock Eclair rom.
Should send back for warranty

software clash?
Well the phone suddenly switched off for me, but this time I turned off APPBRAIN and so far so good.
In fact, I came across an app called NoLED and since it kind of keeps ht phone on, while I have it on my desk, I'm able to be notified of stuff and so far with that, the phone hasnt' shut off.
I'm still experimenting with what works, but try turning off AppBrain and see if you still have the random shut off issue....
i use app brain all the time to keep my apps in sync
not the cause of the problem, that's for sure
my phone can last a whole day even with app brain running
OP, do you have MSN Talk installed on your phone? I have this same problem, seems to happen more when I am running MSN talk in a low signal area.
«try a new sim card. «Could be faulty. «i am on my 3rd phone and all of them had this same problem. «i bought a new sim card 4 days ago, and hasnt happened since. «but then again, this problem usually happens to me once every 3rd-5th day anyways, so i dont know if i am in the clear yet.
Me too, shutdown everyday
Hi guys
After upgrade OS to I9000ZSJG4, Phone random shutdown everyday.
Yep still shuts down
Tried keeping AppBrain off, still shuts down.
Used NoLED so the screen kind of stays on, still shuts off..
So far shut off on me after 40 hrs... this is really stupid.
I am this close to taking it back, but I genuinely think it's a software issue than a hardware issue...sigh
Anyone have any luck figuring this out?
Same problem no solution yet
Hi
I too have the same problem, haven't found any solution yet.
The temperature etc is all good, there is no pattern in shutdown issues.
I have tried factory reset and no new application, it still shut down while using in built browser.
I had the same thing happen to me while skiing in Whistler last weekend. It died twice. I attributed it to the cold. I normally use a 3000mah battery up there, but left it back the house that day. Afterwards while charging in the car and even charging it at home it died prematurely again. It was the eBay aftermarket variety 1500mah knock off. I have since changed back to the Samsung OEM battery. I haven't had an issue with it since. My assumption is that the knock offs in my case cannot handle the heat cycles of charging and then the cold as well as the original. Or they have a limited lifespan, well below OEM specs. I am now only using the 3000mah battery on the weekends to hedge my bet on the quality of manufacture, as it seems to be from the same factory as the 1500.

Has this ever happened to you?...Vibrant seems dead, battey re-install needed!

Since I have got it (2 weeks ago) i have picked up my phone make a call, and on about 7-8 occasions, have noticed that the phone is turned off, and I can't get it to turn on. The only solution is to take out the battery and put it back in. Has anyone else experienced this. I have updated to JH2 firmware, but it still happens. I even got a new battery for the phone (Bell employee let me swap with another phone that was going back to samsung for gps issues), but the problem still happens once in awhile (like every 2 days, sometimes more sometimes less). Anyone have any ideas? thanks
UPDATE: Someone mentioned for me to call my phone the next time this happens to see if it rings. They said it might stuck in sleep mode? Not sure, i just pullthe battery and then it works
I've had this happen, but only when the GPS was on. If it's happening with the GPS off, I'm guessing you've got a lemon.
So far I've not needed to take the battery out, though. I've always been able to reboot by holding the power button down for 5-10 seconds instead.
Yes I have been experiencing the same problem. From what I can see, it seems like the phone is over heating then it locks up. My only fix was to install a battery temperature monitor and also kill any tasks that are not needed by the phone. My phone hasn't locked like that since I've been doing that.

I have not had this problem. Been on a call for about 1-2 hours one time and the phone was fine. I was able to switch it to speaker, bluetooth, open other apps, and etc without any problems. I don't run task managers. I do have one, but I rarely use it.
Interesting...I experienced this for the first time today. Picked up my phone from teh night stand after having it plugged in all night and it was off. Had to pull the battery to get it to come on. The battery was about 85% charged when it came back on. It worked ok since but the battery drained kinda quick. I am using an aftermarket battery, got the 2 batts and charger on ebay. So I put the other battery in and havn't had any issues. I wonder if it over heated while charging? What apps are you guys running? The one I am running that would be most suspect would be weatherbug elite, and I just installed it a day or 2 before this happened.
I think it is a GPS issue. I got this phone on the first day of release. I’ve never had this problem until just days ago. I hadn't used the GPS extensively before last Thursday and Friday. During my business trip I had the GPS on for almost two days straight and during these two days I experienced the blank screen, shut down twice. I had to cycle the battery to get it to boot.
I had this happen to me while using Set CPU. Check out this thread. http :// forum.xda-developers.com/showthread.php?t=727006
take out spaces and what not.
I had this problem on my g1 but it started to get worst an I soon need too keep my mobile always connected to a charger so out turned into a landline phone lol but it was because I somehow broke a middle cell in my battery and need replacing but I don't know what to say about yours cause you tried a different battery :S

Experienced a freeze just a few hours ago while running the navigate application.
Trying to show my wife how uber cool it was and all. Switched on GPS, launched maps, chose directions, method / navigate. GPS locked and had my location pinned down until I reached the corner and suddenly the GPS kicked me to a location about 5 blocks away then froze the phone, requiring a battery pull and reboot.

WiFi stays ON even when in sleep mode

Something very curious has happened the last week or so.
The Wifi stays on, even when the phone is in sleep mode. It is evident when I unlock, the wifi symbol on the status bar doesn't bleep (reconnecting), but stays solid (connected). Of course that could be an operating system displaying error, but it's not; functionality is there, wifi stays on, device connected to the internet. And I'm not talking about the short amount of time that the wifi stays on after locking the phone. I'm talking I'm receiving notification etc as if I was using data.
I noticed it when, after waking up in the morning, I realised a massive battery drop (from 65% to 27%) overnight, although I keep my phone on airplane mode at nights.
As I haven't recently used any mods, regedits etc, and I haven't updated or flashed any rom (btw I'm on debranded stock 8107, with KK2), I can attribute this weird but very interesting behaviour to 2 possible things:
a. I installed some app, possibly homebrew, that somehow (even the dev didn't know about that) keeps running keeping wifi awake under lockscreen
b. Maybe it's because I'm on Airplane mode. I kept on being on Airplane mode from the moment I noticed it (as I have input my SIM to another phone). I should note though that there is a sim in the phone, I'm just on Airplane mode. Is that a known feature? Wifi stayin on under lockscreen on Airplane mode? I don't think so, as I would have noticed all that time (I keep my phone on that mode a lot).
That behaviour has persisted after soft-resets (reboots) and battery charges. The only hardware change I made the last week was using a non OEM replacement battery (the ones that reboot the phone when connected to the charger). But I'm using the original battery.
I should note it consumes about 4% of battery life for every hour, quite viable.
thats weird, but to some ppl, like me, i'd be happy if this happens, would love wifi staying on in sleep mode.
but, the opposite happens with mostly everyone
Even more curious thing that I found out today. When the phone is SWITCHED OFF, and wifi was on before switching the phone off, I have battery drop (almost the same as if being switched on with wifi on, around 3-4% per hour, in my instance from 43% went to 11% when I switched the phone on).
I don't know if the (original) battery has been messed up, so the battery index is not reliable (the reason I bought replacements was that in a span of 1 month, I was not treating it right, a lot of charging, heavy operation simultaneously, resulting in excess battery heating etc), or for some reason the use of the fake battery messed up the software part (both battery metering and WiFi stayin on)
I'll do so more testing and I'll report. Has anyone tried to go to Airplane mode and switch on Wifi, to check if it stays on under lockscreen?
It stopped today... weird!
... And it happened again, this time I think it might have been triggered by Audible, I might make a video as a proof.
EDIT: I was making that video, and realized on cam that it stopped happenning, and then I realized I had flashed beforehand the KK4 firmware. What a douche! If it happens I'll try to capture it on camera
When the data connection is OFF (like when you activate airplane mode) wifi remains connected even when you lock the phone.

No that doesn't normally happens, unless you have an app running under lockscreen and using WiFi (like a music streaming app)

Nexus 4 switching off at night while charging

I know this has been discussed plenty of times but I just have some more questions of my own I'd like to ask.
So my N4 just switches off over night after being charged to like 95-100%.
It is usually fully charged (green LED) but won't turn on if I want to wake the screen.
I have to hold the power button for like 5 seconds for it to switch off. Then I am able to boot it again.
If i just unplug the charger, wait like 30s to a minute, the screen will wake, it works as usual. But the phone restarted (!!!) without any boot animation or anything. Just like nothing happened. If I then go into settings -> battery you can see the phone switched on just a minute ago.
This is happening like everynight for me now, so I had to use my old phone as an alarm clock as I slept in quite a few times actually
I searched like all forums and tried everything but I cannot dissolve this issue.
I even turned off deep sleep in dev options and stuff alike, monitored temperatures and stuff. Nothing conclusive though.
So I just have no idea why this keeps happening.
It happened with different roms and different kernels. Root or not rooted.
A friend of mine has a N4 as well and he does not have this problem at all. He does not have a custom rom flashed or anything.
But I read on other forums that even users with stock rom had this problems.
I think this is a quite common problem with the Nexus 4 device, isn't it?
Anyone solved it yet? Or does at least know the CAUSE for this?
I mean srsly there is like nothing on the forums..
Is it software related? Hardware related? Did I **** something up?
Is this a valid reason to send my phone back to google and get a new (working) one?
Everything else just works flawlessly. I mean the N4 with PA on it works so smooth like a charm.
I DO NOT WANT TO GIVE IT BACK!
noone? really?
I don't remember this being a common problem, though maybe I missed something.
If I was you I would wipe everything and re-flash stock. Then if it still happens return the phone, it shouldn't be doing that and I wouldn't put up with that if it was my phone. But it's your choice.

I have the same problem and I believe that this and similar issues are becoming increasingly mentioned on various sites on the net. XDA tread - http://forum.xda-developers.com/showthread.php?t=2077148 which gives some idea as to what people are doing to get to the bottom of the problem.
There is further info here - https://code.google.com/p/android/issues/detail?id=35139 which starts with Sleep of Death issues on JB4.1.1 (on the Galaxy Nexus but has more recently focused on the Nexus 4).
Initially the problem occurred maybe 3 times a week. I'm running a Stock N4 and whether stock or custom does not seem to make any difference.
I re-flashed a stock image and thought I had solved the problem. The phone ran okay for a few weeks and then reverted to random SOD's normally at night whilst charging. If I use airplane mode at night I have no problems. It has also become unresponsive/deep sleep on three occasions during the day. More recently I have stopped leaving wifi enabled unless I need it I no longer use airplane mode and have not had any further problems --- so far ---
For me at least, the problem might be wifi related.
This happened to me this morning. I have my phone on charge every night and it probably hits 100% about 3am every morning. I have the alarm set at 7am to wake me, and has done every morning since I got it last month. However I have now slept in twice (this morning was catastrophic) due to waking up to find my phone was switched off and my alarm subsequently didnt sound!! I have wifi left on, but all my apps are closed down, and only the alarm app running.
To switch it back on I have to hold the down the power button for in between 5-10 seconds for it to reboot.
Does anyone know why this is happening? The Nexus 4 is perfect in every other way, I'm gutted to find a fault after raving so much about it!
Same thing is happening to me every night !
I have the same problem, but it happens sporadically, so I never know when I'm going to end up sleeping in. It's infuriating.
It just happened again this morning. I had Wi-Fi disabled, so I know it has nothing to do with that.

Sounds like a rogue app is triggering the phone to crash or something?
Have you tried a factory reset?
This bs caused me to be late to a final exam... I was so mad when I woke up and saw that it was 2 hours later than the time my alarm was set to sound.. Only started happening with 4.4+ updates.

Hey man,
My girlfriends nexus 4 did this as well and she got it RMA'd with no questions asked and a brand new one sent out, they told her to do a factory reset; this worked for a few days then went back to normal again.

Charging cable
I have had this problem eventually with every android phone I've ever owned but it seems by replacing the charging cable with a new one the problem goes away. It seems that there is a weird thing with android where if the cable doesn't sit completely snug or straight the battery can charge but the phone won't realize this and go to sleep. Also seen the opposite happen where the phone thinks that the battery is charging and in fact it hasn't. When you unplug it suddenly goes from full charge to nothing. Haven't seen that last one on my Nexus 4 yet though. So I would try replacing the cable (not necessarily the charger) usually worked for me on other phones. Also I would suggest not to leave the phone and cable hanging off the end of a table. Make sure it's in enough that it sits flat. I think this is how I slightly bent mine.

Screen randomly turning on?

Just got my Priv yesterday, and loving it so far, BUT I noticed all day today so far my phone has been sitting next to me on a desk and the screen keeps randomly turning on. I went to Settings -> Display and disabled "Ambient display" and "Lift to wake" thinking that might be triggering it, but no luck. The display keeps randomly turning itself on and draining massive amounts of battery. Has anybody else had this problem or do I have a lemon of a device?
EDIT: I also noticed my device does not sleep "After 30 seconds of inactivity" like I set it to, or any amount of time I set it to for that matter. Anybody else have this problem as well?
I had the screen randomly waking issue too. I had to turn off Lift to wake for that to stop happening.
I also get the issue where the screen doesn't sleep even if I set the screen to sleep after 15 seconds.
You are not alone. lol
Ok so it's not a hardware issue on my end that's the good news I guess. The bad news is this issue is killing my battery life so it might be a deal breaker unless we can find solution.

You wouldn't happen to have an Android Wear watch that's connected to your phone at all, would you?
Or possibly trusted devices or places setup at all?

Check to see if the wake screen for new notification alerts are set. I had a similar issue when I first got the device but after turning this off and the lift to wake option my battery life has gotten much much better
So I restarted my device and the issue went away, then toggeled the Airplane mode on while I was in school (I'm a teacher) and turned it off when I was leaving school and noticed I had the same problem again.
Can one of you test to see if toggling the Airplane mode on your phone makes the screen timeout no longer work?

Just checked mine. Screen timeout working as it should when Airplane Mode activated. Hope you figure out what the problem might be. Good luck
After I got the PRIV I also noticed it woke up too easily. After disabling the 'Double-tap to wake' option (don't know the exact name) that didn't happen anymore.
