Sleep - Nexus 7 Q&A, Help & Troubleshooting

Ive had my nexus 7 since it came out...no problems until recently...over the last few weeks I've been having trouble getting it to wake up...meaning if I'm reading and just shut the case to turn off the screen...when I go to use it in the morning I have to hold the power button in for 10+ seconds to get it to restart...
Doesn't matter which rom I use, it does the same thing!!!
Any ideas?
THanks,
Mike

I reflashed stock and that solved the problem for me. I'm currently on a custom rom and I've never had the problem since.

[Q] Nexus 4 randomly turning off, intermittently not being able to restart

Hi guys,
Not exactly the most positive of first posts but here we go. There's a problem with my phone that I can't find the solution for...
Essentially my phone randomly turns itself off (no power down sequence, almost as though the battery's being taken out if you know what I mean) and then it has difficulty in fully booting again. For some reason it also likes to revert my wallpaper back to the original as stock.
The first thing that I thought of was malware, with the wallpaper - so I tried a couple of anti-malware apps to no avail. As my device was rooted, I then flashed back to stock, locked and unrooted it and checked the behaviour. Again to no avail (then again I've never rooted/unrooted so this may have been done incorrectly). By the looks of it, the worst case scenario is a problem with battery connections/hardware...
So the question is have you guys come across this before? Is there a solution to this or is Google/LG going to have to give me a replacement?
Many Thanks.
Weird, I just had this happen couple hours ago, I was watching a video and close the app. I press the power button to put it to sleep. Just like 20 second later, I press the power to wake it and it don't do anything. I had to hold the power button to turn it on. I check the battery status afterward and it looks like it drop between 5-10 percent in the chart after it turn on. The battery must have failed or something. This also happen to my wife phone couple weeks back, although she had to do a hard reset(power+volume up and down) it have not happen again though.
Hello
First of all, welcome to XDA community!
Now, have you done anything with your phone? As in, root it? Flashed custom kernel? Flashed custom ROM? We would love to help, but you need to provide us what we need

Okay, here's what I had done when this all started:
- Rooted and unlocked.
- TWRP custom recovery
- Standard Kernel, no custom ROM.
I've reverted as much of this back to stock as possible through a nexus tool-kit, but it still has the issue. If I'm missing anything out let me know.

Did this happen before you had the phone rooted? Also did this happen one time only or happened multiple times? I also had this problem, but just turning off and not turning back on part. But that was only one time event and I believe it was because of the custom kernel.

This started yesterday, and I rooted it as soon as I got it 2 weeks ago, so I don't think the root has caused any issues. It's now happening rather often, to the point where it's unuseable

That's odd. Did you download any apps recently that might've caused this issue? Maybe root apps?

The only 2 apps that I downloaded the day before were cerberus and titanium backup, both of which are well known. Either way they were the day before the problems started.

Doubt that these will cause any issues, but could you try uninstalling Cerberus just in case? Thanks

Well, after completely reverting the phone back to its stock version and pretty much everything else, it's still doing it - which surely points to a problem with the chip (or something). So, I've contacted google about a replacement and so far so good - got through in 5 minutes and sorted out the RMA and everything, should be delivered in the next few days.
Thanks for the help anyway. I'm going to avoid rooting this one for the time being to see how it behaves.
I experienced "random shutdowns" and even posted about it here. Turns out it was my belt holster that was somehow the culprit. I don't know if it was mashing some weird button sequence to turn off the phone, or if the magnet interfered or something else, but as soon as I got it out of that holster I had no more random shutdowns.
I doubt yours is the same problem but I thought I'd post mine.

Yeah that's not my problem at all Lol. Glad you've figured it out and I bet that magnet caused the issue IMO

Funny I had the same thing happen to me last night. I was using the phone put it down for a minute or two and then could not wake the phone. What was interesting was when I couldn't get it to turn on I plugged in into the charger and let it sit for a few hours. When I was finally able to restart it using the the power, vol button the battery was at the same level before the incident. In other words whatever happened prevented the battery from being charged. I am stock and rooted and haven't loaded any new apps in over 2 weeks

I have almost the same problem as the op but I do have a shut down sequence. It does randomly shut down itself. The first thing I got the phone I rooted it and it was fine working on modaco for 2 weeks then one day it kept shutting down upon boot until like 10 tries later I successfully got back in but lasted only a few mins and sometimes hours. Im gonna rma this pos and I hope I can get it replaced soon. I try it with stock rom and kernel then modaco with stock kernel then modaco with faux kernel. Same problem.
I had these problems earlier ... I just gave HARD RESET by pressing power key for more than 5 sec.
Then i figured, it was due to Undervolting ! and Processor going to a DEEP SLEEP all together !
So i removed UVing and it was cool since then ! ... Although my signature says the rest !
I bought my N4 about 2 weeks ago, and it has turned itself off 3 of the nights I've had it. I don't have any hard evidence, but I have a theory on why it's doing it.
At first I thought it was because I used a Motorola usb cord instead of the stock cord because I read some people's theories on the internet, but it happened again (twice) after using the stock cord.
It seemed like it only shut off if I left WiFi turned on when I went to sleep (even then it was still a random occurrence). I went into my advanced WiFi settings and noticed Wi-Fi Optimization was turned on with the text "Minimize battery usage when Wi-Fi is on". I thought it might be the problem, so I turned it off. I left WiFi on last night, and the phone was still on in the morning. Again, it is still a random occurrence even with WF on, so I'm going to leave WF on at night for a few days/weeks and see if it happens again. I'll post back with results.
If anyone else has already tried this or has figured out a solution, let me know.
The same happens several times a week with my nexus 4 running latest cyanogenmod. I will revert it to clean stock in a few days to see how it goes. I don't think that is a hardware problem but time will tell.

Don't know if anyone is keeping up or cares, but I wanted to update and say that this did not fix the problem. 4.2.2 also did not fix the problem. I guess I could try getting a new one from Google.
My wife and I are both having this problem. Hers is completely stock, I'm unlocked and rooted. I was hoping it would be fixed with 4.2.2, but if it hasn't then it maybe time to get replacement N4s
I can't imagine this issue is very widespread, since there have only been a few threads about it. Its a big nuisance especially because it usually happens at night when I'm expecting my alarm to go off at night.
I hadn't wanted to send for replacements since it seems like a software issue but I'm getting fed up.

Just had this problem occur with my N4 last night..... Phone is 2 weeks old.
Went to bed, plugged in the phone to charge [it was at about 50% or so, so not exactly low].
Woke up at 8.30 wondering why my alarm didn't go off at 7.30.... looked over and the phone was off.
It also didn't want to turn back on either. Took about a minute of holding in the power button for various amounts of time before it finally kicked to life [at 100% charge too].
This is going to be a real problem if this problem reoccurs. At home I have a clock radio but I travel a lot and rely on my phone to wake me up!
Here's hoping we can start to identify what is causing this issue. All I can add is that it is not low-battery related.
As stated in the sig. Phone is unlocked/rooted with stock rom.

[Q] Phone turning off by itself and renders itself off ever since

Hi all,
My first post here and I'm posting it at a pretty depressing mood.
I've just bought my phone from the states and brought it back to Hong Kong for my own use. Last night, I've been toying it for a couple hours with everything going perfectly fine, but suddenly the phone turned itself off. Everytime I try to turn it on the phone just turns itself back off again. I couldn't do anything.
Has anyone come across the same problem? I've done a hard reset but to no avail, the phone still shuts down right after turning on, it's pretty frustrating to turn on your phone just to see it telling you it's turning off, really frustrating tbh.
I've called google and requested for a replacement so problem's kinda solved for the moment. I just want to know if I'm alone here because I've pressed the operator a couple times and she refused to tell me if mine was an isolated incident or not, for obvious reasons.
I haven't done anything to the phone except installing a couple apps like Aldiko, whatsapp, facebook and a Chinese keyboard (since I'm Asian apparently). I've installed all of them in my old phone and none of them caused any problems so I just want to know if I'm alone and what do you guys think the root of the problem is, or solutions to it if there are any.
Thanks a lot!

Mine is happening the samething, glad Im not alone. My was running fine on rooted Modaco custom rom for a few weeks then all of sudden the phone auto shut down like it has its mind. I installed Cantonese keyboard and camera mod too and some other apps. Currently Im tracking down the source. Now I have franco kernel and madaco rom on clean install running with no other app install to see if it will shut down or not. If it does Im going back to stock to see if samething happen.
I have to boot it couple times until it doesnt shut down itself anymore. Sometimes it be stable for couple hours or couple minutes or instantly.
I have the same problem, Just got my phone from google everything is stock nothing has been changed and the phone just turns it self off and then i cant turn it back on for sometime.
Does anyone know what causing this problem?
Mine also turns off multiple times a day, sometimes by itself, sometimes during a call, often when taking a picture.
Today every single time I took a picture it would shut down.
I'm f*cking pissed at waiting 5 weeks to get a useless phone... and god know how long it will take to get a replacement if I ca get one.
Hi guys, I have the same problem too
I've used my Nexus 4 for 2 weeks without any kind of problem when suddenly it turned itself off. If I try to turn it on, the phone just turns itself back off again and I haven't solved the problem even with a reset.
But I've noticed that the battery doesn't charging even with the charging cable. I think the phone detects that hasn't enough battey level and for that reason turns itself back off.
Do you think it can be an harware or software problem?
Damn - i have recently been having the same problem! It only happens (so far) when i'm charging the phone overnight. I wake up and it's off and takes a few tries to get it running again. I'm rooted with stock. Does this mean we all need replacements? Ugh!

The exact same thing happened to me as well. I charged it overnight, unplugged it and it was off. I couldn't even turn it on again - I had to keep holding the power button for ~15 seconds plus try plugging/unplugging the phone to the charger etc. and it finally powered on. I orginally thought it may have been a kernel issue since I had just flashed Franco r29. However, looking at his thread, nobody had that issue.
I'm glad I'm not alone but this issue really worries me, especially if it is a hardware fault. Google will replace it but I don't feel like going through the fuss since God knows when the replacement will arrive. I hope this get's 'magically' fixed as it has only happened to me once so far.

You know, I'm looking at my battery history (using battery monitor) and i see the period that the phone was shut down and then when i powered it back up this morning and i notice the battery temp is extremely high so it probably has to do with the phone shutting down due to overheating, which obviously shouldn't happen. I wasn't using the oem charger, so I'll switch to that for the time being and keep an eye on temp. Hopefully it's a software bug and not a faulty battery because it should definitely be cutting off charging when it reaches 100%.

[Q] Nexus 4 Freezing frequently

I have been using my phone for more than 4 months now.
Till now everything was fine, but 2 days I noticed my battery was draining very quickly and yesterday suddenly my phone started freezing while using it. The only way to reboot is by pressing the power button for 10 seconds. I also noticed that it never happens when the phone is charging. I phone is running stock rom. I tried reseting it but still it is freezing. So I wiped the entire phone memory and flashed the stock OS again. But the problem is still there.
Somebody please help me. :crying:

Funny I'm also in the same situation. Recently restored from a backup ( from 301k nexus 4 to my current 303k nexus 4) and lately ive been getting a load of lockscreen sleep and my phone constantly restarting or I'd have to hold power for a few seconds.
Just wondering if maybe i should reflash rom as a whole? ( i already reflashed kernel if anything.)

You could reflash the factory image but first make sure this isn`t caused by a runaway app/widget. Most of these problems are caused by user apps most of the time. Install BetterBatteryStatts and cpu spy for app behaviour and cpu deep sleep.

Earlier when I used to restart my phone, the battery app used to show a huge drop in charge, but now the battery app resets itself and shows that the device was on battery only since the restart.
I am getting frustrated, now whenever my phone is inactive for 10 mins, the phone wont unlock and it crashes

Another thing I noticed is that the phone works perfectly when it is plugged in and when on battery, it wont hang till battery level reaches 91%-93%, but after that as the battery level drops the crash interval becomes less. When it is around 25-30% the phone sometimes freezes even during restart. Will it be a battery problem?

Constant freezes. Resets on its own.

Installed Android Marshmallow last night. All seemed to be working well until tonight. I've plugged my phone in to charge and it's instantly got super slow then turned off. Wouldn't turn back on for love nor glory for a good 10 or so minutes. Then it finally did. However, it turned on, worked slowly for about 15 seconds then either froze in which I'd have to hold the power key and volume down to turn it off or it'd turn off on its own and reset.
It's been about 4 hours now and still doing it.
Any help at all please? Thanks.

No WiFi connection

I got 2 LG G2 d800 and both started not connecting to wifi, it gets stuck on "turning on wifi", both happened on the same day so I don't think its a hardware problem probably an update of Google services, anyone has the same problem and maybe a solution?
Sent from my Nexus 6 using Tapatalk
I am experiencing the same problem since yesterday. It just says Turning Wi-Fi on... and it never turns on. It happened when I had my phone charging and noticed a facebook messenger update. The wifi has turned on and worked for a while (especially after some reboots) but then it got back to doing the same thing again. I have reset my phone but it doesn't let me do a hard reset using the power and volume down keys.
Any ideas on how to solve this?
sorry to say, but its broken (99%). i had the same problem. but my luck it was i guarantee time (short before end)

I have made it work for a few hours, somehow. I finally managed to figure out how to factory reset it. I did it a few times until the wifi was working completely.
I started downloading apps and it worked perfectly. Then I decided to try a reboot and the wifi when out again. The difference is that now I have a MAC address and before I didn't. It's still stuck but there's some progress, I guess.
I thought about rooting my phone, but I'm scared of ending up with a brink since I have never done it before.
Me too with my g2:
About 3 weeks that my wifi, hot spot & the stock radio app aren't working like they used to for 4 years!
Did factory reset but it didnt helped
