[Q] Cannot wake up device from sleep - Nexus 7 Q&A, Help & Troubleshooting

So I've had this problem for some time maybe a couple of weeks.
The problem is that I sometimes cannot wake up my device after setting it down for sometime. For example if I go to sleep get up the next morning and then screen will not turn on. I have to hold power button down for multiple seconds and press it multiple times. Also one recent occurrence of this there was massive battery use. See attached photo.
If anyone knows why this is occurring or knows any remedies that would be appreciated.
Using PA 2.54
Franco Kernel
I can provide more information if needed. Just ask.
Thanks

I was having serious issues with my 16gb. Very hard to turn on, sometimes hold power for 10 seconds, sometimes 30, sometimes 5.. all over the place. And it only started after I believe the 4.2 update.
Also, it was draining battery while off. Charge it overnight, leave it off the entire time, come back 8 hours later. Turn it on and only have 50% battery.
Sometimes the charging animation would lock up while off as well. And if the device was turned off, and you plug it in to charge, it turns on. It shouldn't.
I think I've narrowed it down to the bootloader. My bootloader was at 4.13, and Flashing the 4.2.1 and 4.1.2 factory images didn't help.
Last night I finally fixed it. I ran the 4.1.1 factory image. Which put the 3.34 bootloader back in place. This wipes the device. So I flashed the recovery back and then reflashed Paranoid Android 2.99B6. All is good now, it turns on like it should, doesnt come on when plugged in, etc.
Meanwhile a new 32gb I have I can flash the 4.2.1 factory image, and I have no issues with that one.
Which bootloader are you on?

Hmm. That seems to be the exact same issue I have!
I just checked my bootloader and I have 3.41. But I never went up to 4.2. I stayed at 4.1.2 with PA 2.54.
Hmm. Maybe I'll try what you tried!

You can flash the 4.1.3 bootloader from JB 4.2 and use it with 4.1.2. I am, and it works perfectly and I never have a problem booting or bringing it out of sleep mode.

I think it was just your Franco kernel. Kernels are typically the cause.
I'm running PAb6 and no problems.

Hi, which kernel are you using? I just changed my bootloader back to 3.34 and my kernel to motley. See if that helps.
Thanks for the tips.

seems after flashing a new kernel to motley the problem still occurs...
I think ill factory reset. reinstall PA gapps and everything... see what happens.

anyone else have any insights into this... flashing a new kernel and it still occurs

Sometimes you have to set you're minimum cpu frequency above 200 using one of the various cpu or kernel tuners

Just had this similar problem. I drained the battery to about 11% on wednesday night, so i shut it off and charged it to 100% on that very same night. Turned it on on friday night (It should have been turned OFF all this while) and it wont start. After the help of the AC charger, it came back on and found out the batt was at 0%. Which should not be the case even if the tablet was accidentally switched on because theres no way it can drain from 100% to 0% in just 2 days. And everytime i leave it plugged into AC it suddenly turns on and shuts down due to low power. Am using TWN ROM V1 (Android 4.2.1) with M-Kernel A17 kernel if that has anything to do with it.

So I think I have it figured out that if I set my wife policy to keep awake always no problems, but if it is set to keep awake only during charging, I will have problems
I will try it out on a higher cpu setting with semi awake

Just wiped the device and flashed CleanROM 3.0 on it and NOTHING else (No extra scripts, custom kernels, radios..etc) and it seems to have been stabilized. Although the battery drained pretty quick while i was using it last night, but I was installing apps and setting up stuff on the nexus so its not a very accurate benchmark. Will continue to monitor.

Hmm, I see. Well that's great that you solved it
It seems after switching my minimum cpu to 200. It still froze when I was trying to wake it up this morning
Maybe a full wipe is needed...
Sent from my Nexus 7 using xda app-developers app

Yes you should have done a full wipe like I did. All still seems to be good on my side. Looks like for my case it was M-Kernel a17 causing the problem. I doubt such a thing would happen due to a faulty bootloader.

So I did a full wipe of my tablet and instead installed PA 2.99 b6, flashed correct gapps, then flashed the beats audio v3b2 and the same thing occurs.
im using franco kernel v30 no OC just gpu oc to 446.
my tab if i leave it unplugged and set wifi policy to keep wifi on during sleep only when plugged in I get this problem that I cannot fix... which is the tablet freezes or something and i cannot turn the screen back on until i hold the power button, Then turn it back on. Also on a side note for the first time this morning, the back of my tab was hot, which never occurred when i was on PA 2.54
Any insights on this issue anyone?

full wipe and flash a ROM that comes with the stock kernel. I did that with CleanROM 3.0 and its still working fine to this day. Will probably try flashing franco or M-kernel again when I have the time. But for now it seems that a custom kernel might be the issue here.

Thanks for all your replies. It seems to have fixed it after updating my ROM im really not sure what happened with PA 2.54 but with PA 2.99b6/8 it has not freezed at all, but then again the min cpu freq i have is at 340 heh...

Is the battery dead?

My Nexus 7 was flashed with MIUI a week ago, I tried getting new ROM to flash it it went bad and since then Nexus 7 was off (so around a week in bootloader screen).
I got time today so flashed Fusion ROM, N7 reboots immediately after booting since battery is 0%.
Stock ROM runs until power/USB is connected.
Does this mean my battery is dead? If yes what are my options. If no what can be the solution?

[Q] Wireless charging not working correctly.

I got the official Nexus 4 wireless charger from Google around a month ago. I constantly use Tunein Radio, and like to use JellyDream Daydream Pro when I put my Nexus 4 to wirelessly charge on my desk. I have noticed that my phone will not charge and remain with the same battery percentage for hours, and many times even continue discharging (slower than usual though). I was wondering if this is normal, or if there might be a problem with my wireless charger/phone. My phone is rooted, but I don't think it's the rom that I'm using, because I have tried both Paranoid Android, and AOKP with the same results. If anyone could help, it would be greatly appreciated. Thank you.
I am having the same issue. All I have changed on the phone is the kernel and have always been on stock rom. It's really annoying because it worked perfectly fine before I flashed kernels. Now I can even flash back to the stock kernel and it will still not work right. Jumps in and out of charging and then finally just stops charging all together and I have a fancy phone stand that does nothing. I'm still trying to tackle the problem but no luck so far.

Yeap, apart from what I said on the main post, I have also experience my Nexus 4 jumping in and out of charging and then not wanting to charge at all.
Maybe you are discharging the battery faster than the wireless charger can charge it? Using tunein radio and daydream will do that.

[Q] Deep sleep reboot or something else?

So, I've been running the Milestone release of AOKP for a while and while it's been generally stable, I seem to be having an an issue with reboots when I don't use the tablet for a while. Maybe.
Once maybe every few days, if it's been sitting for a while (or charging), when I unlock, all of my recent apps have been cleared. The stock battery info doesn't indicate any downtime, but GSAM battery monitor will indicate a reboot.
I've seen this on both KToon and Franco's most recent kernels.
Anybody else? Any ideas?
Thanks!

My aokp+franco also falls asleep and I nave to reboot. It's annoying, I'm going to change ROM. I'd like to know if it is related to the ROM or the kernel though.
I'd guess OP is seeing 'surface flinger RAM shell reboot' that's talked about often.
I'd guess europizza has a unit that is having a battery/motherboard/"power" related issue.
Why? - Based on reading these and other N10 help forums for the last 6 months.

While I have had the SOD with AOKP and Franco/KToon kernels, what I'm talking about isn't the tablet not waking up. It's that it's rebooting while charging or not being used for extended periods of time. (But I haven't had any SOD issues with the latest version of either of those kernels, btw.)

Ah, thanks. I've seen talk of this surface flinger business before, but never really knew what it was referring to. Haven't researched it much yet, but it sounds like something I'll just have to deal with for now.

Touchscreen dead on wake, reboot fixes

Anyone got an issue where after some time (can be one week plus), you pick up your tab and the touchscreen is completely unresponsive on the lockscreen, can't even press powermenu? Reboot fixes. I had it on JSS1J and persists into JSS1Q. Hard to isolate as it may not happen for say a week of uptime, seems to be no pattern or consistent trigger
Sent from my Nexus 7 using Tapatalk 4
I been getting the same thing. Charging over night the tablet wakes but touch is unresponsive. I'm on Clean rom and Elementalx kernel. Yesterday morning after 8 hours on battery and unused it woke and touch was fine. This morning after 6 hours on charger, over night, it woke and touch is fine. Need more testing.
Note: yesterday afternoon I update Elementalx kernal to 1.3
Yeah elemental or stock it happens

I see this from time to time on mine. What sucks the most is when the damn alarm is going off and I can't do anything but hold the power down to reboot. Wife loves this "feature" in the early AM.
I have an unlocked bootloader but I'm running stock kernel (3.4.0-g6537a16) and stock JSS15Q. I do see random reboots as well, seems to be related to the screen going to sleep by itself but I can't reliably reproduce it.
Happens to me as well. Annoying.
I had this on stock locked so its nothing to do with bootloader or custom kernel/ROM.
Curious if a CM based ROM will affect this i.e. not stock JSS1Q based.
Is everybody facing this touchscreen issue? I am planning to get the new nexus 7 2nd Gen from canada. Is it something you can discover in the first week itself because the person who is bringing it will get the tab a week before her return.
If you're lucky it'll show up in that time period.
Others have gone 10 days.
Have them put off buying until the last second....
Same thing happening to me. The screen becomes unresponsive. Happens in the morning when the alarm is going off and have to reboot. I just updated to ElementalX 1.4 and hoping it'll fix it. I'm hoping Google comes out with an update soon because my screen sensitivity sucks sometimes. It's not registering my taps.
It doesn't lol it's either hardware or something in 4.3base

My one, after 10 days, dead, the touch screen has no response at all
sent back to repair for over 1 week, still no news on when can return..
really bad feeling with this Nexus 7 (2013),
only Nexus 4/7/10 has no problem and still working well till now.
I faced this as well. But it solves itself.
Sent from my Nexus 7 using Tapatalk 4
I experienced the same issue here. However, I am not able to reboot as I am still running on stock and don't have the debug option enabled. Pushing the power bottun for some time only brings up a menu where i may chosse to shut down. As the touchscreen is not working, I cannot do anything. Unfortunately, my battery is almost completely charged. Any ideas how to reboot?
Coincidence: The touchscren went unresponsive after the alarm clock went off. Maybe there is a connection?
Here's hoping JSS15R fixes this (fat chance hah)

Hold down the power button until it reboots.
I had this issue exactly once since I got mine, and it's been fine since. I suspect it's a hardware or driver issue.

Android 4.3 Bugs

I've been having problems with stock and unrooted rom.
1. Volume keys don't work at all and have to reboot to fix.
2. Nexus 4 would freeze and would have to reboot.
3. I don't know if its software or hardware, but nexus 4 would be unresponsive to turn screen back on and would have to hold the power button to reboot
Anybody with these issues?

Good morning, haven't used the phone. But hopefully it doesn't come to that. I used to be a crazy ROM flasher, and never got to enjoy the phone as it is. Its been months since I have flashed my phone lol I feel like I'm on rehab lol the reason why I don't want to factory reset or flash a ROM, it's because it takes about an 1 hr for me to set it up the way I like it lol thanks man! Hopefully they release a minor update to fix these bugs at least

I have face the symptom 3. Removed couple of newly installed files and no issues from last 14 hrs.
Now the reboots are getting worse; during a phone call it rebooted, screen off and doing nothing, and using chrome. I hate to do this but I'm going to factory reset. And by the way, what files did you delete?
Deleted word web & some regional specific app. Resetting phone should be fine without any issue.
I have formatted yesterday, its great no issues & battery life seems great.

I've experienced Symptom 3 a few times. Tried a few kernels and same result. So far I've stuck with Franco kernel and I overvolted by +25mV -- seems to have improved things a fair bit.
May end up doing a factory reset and re-loading the 4.3 image to see if that clears up any outstanding issues.
I think I've figured out the solution. Chrome Beta 30 is the one that is causing reboots stated in the link. I would get random reboots and would blame it on my power button. Happens for no apparent reason, during a phone call and while listening to music.

Hi all,
I bought my phone one week ago, and during this week it froze on me once on stock 4.3, not even rooted.
Over the weekend I flashed CM official nightly and I got a 10 second "freeze"... I waited it out without doing anything, after 10 seconds it "unfroze". Anyways, I've been reading that update 4.3 isn't all that great... I hope they're able to pinpoint what's causing these random freezes soon!
It looks Google isn't going to release android 4.3.1. Since rumors are stating that they are releasing Android 4.4 on October 14. Its only a rumor though. I wish they would fix this bug at least.

Thats a deadlock, it's a known problem with 4.3 JSS roms like CM 10.2. If you flash a JWR based rom it doesn't have these issues, or a hybrid JWR/JSS rom like PA.
I keep getting these annoying errors, both on camera and on media folder.
