Full battery drain caused all core apps to fail, even after recharge...

Anyone have any idea what may have happened here?
I was unexpectedly away from home, but using the device quite heavily, and didn't have a method to charge the battery.
Once the battery had drained to about 3%, I switched the phone off but I ended up needing to make another call. The phone booted, but all core apps returned a force close message. Phone, Maps, Google Account, all the main stuff... Other apps would launch and function with no problem though.
Thinking it may have just been a glitch, I rebooted the phone again thinking there would still be just enough juice to allow a phone call, but while booting, the battery totally failed.
Once I had a chance to plug in the charger, all core apps continued to fail, even though the phone now had plenty of power.
Even after a battery pull, the same issues continued, rendering the phone pretty much useless. No link to Sprint, no WiFi network, nothing...
The phone is rooted with v1.5.2 RC and Fresh ROM v1.0, so lacking anything else to do, I performed a Nandroid restore from a backup made about 2 days ago and that seems to have fixed up the problem. (whew.. I did not want to resort to the RUU)
But, I just can't figure out what may have caused this odd behavior in the first place....

Are you using apps2sd?

No, I'm not using the apps2sd feature.
The lockscreen text showed "No service" and the notification bar icon showed the same. The "phone" application was the only one that would attempt to restart after being forced closed. After a second fc though, it would apparently give up.
Oh, and just remembered one other oddity.. Once booted and all force close messages removed, attempting to turn on the mobile network resulted in a hard reboot. I really didn't expect anything since there was no service link, but I was just clicking various shortcuts to see what did or didn't work.
Good part is that a Nandroid restore saved the day, so it's more of a curiosity at this point to what the root cause might have been.
I wouldn't have thought that a battery drain could have corrupted the apps or prevented the root filesystem from mounting.

You probably had too many apps installed. It's a known issue with the Hero, where having too many apps installed causes a bunch of core apps to fail to load for no apparent reason. The phone losing power just caused it to reboot, which triggers the issue.

oddly enough I've had a similar experience. it was 2 days before christmas and i was doing all my last minute shopping. heavy use of the phone caused the battery to die, so i just threw it on my car charger. it booted, but REFUSED to get any data at all (i didn't run into any fc's, however). I rebooted it 3 times and each time the issue persisted.
I was running the AOSP 2.0 build at the time, so i flashed my backup of 2.1 and everything was fine from there...

Hmm, good possibility there. Just did a count and I do have 85 apps installed.
(whoof, I had no idea the number had gotten that high. just too many useful apps for this phone.

[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] Wi-fi connectivity issues

After a recent snafu in trying to remove root from my Nexus 7 tablet and installing the 4.3 update I think there are issues with with it's ability to keep a constant wireless connection, Juice Defender be damned as way before root and even during root I was able to maintain a flawless connection although I think the issue may have arisen during my installation of a cracked google play store app.
This was a couple months ago though.
However I decided rooting wasn't worth it and wanted to update to the new 4.3, this is where the snafu occurs, unrooting wasn't a problem at all, nor was flashing stock recovery, but the process of installing 4.3 was since even performing the update in my settings wasn't working, it would download and my tablet would restart and try to apply the update but soon after it would error out and I had to perform a hard shut down.
After that it would boot like normal and there were no issues, other than the update failing to apply.
So I decided to try and apply the update manually and as it turns out, I was attempting to install the update for the mobile version of the tablet instead of the wi-fi only one that I have so it didn't install correctly and simply erased all data on my tablet except luckily for the devices fastboot mode.
Seeing that I installed the correct 4.3 factory image and this is where the wi-fi issues come into play (I wanted to explain in as much detail as I could that might shed light on my current wi-fi situation).
The tablet booted up seemingly normally, taking a bit longer than it should have to me and upon getting to the glowing X before the main screen it suddenly reset it's self and then booted up correctly; so I finished the set up process after linking my wi-fi up but while going through each app that uses wi-fi I started off with games like Happy Street and The Sims Freeplay which worked normally.
Then I got go my Bank of America app and it's the one app (besides the Play Store on occasion), that didn't work at all, instead it just timed out, there's a screenshot so you can verify for yourselves.
You can clearly see I do have an established connection but this is the only app that fails to work after the update, again besides the Play Store but I've removed root and the crack is no longer installed, not that it would work anyway without root access but it doesn't concern me as much since it'll connect after force closing the app and starting it again.
So that's my issue in detail, is there something that I messed up that's preventing the device from maintaining a connection? Or do I simply need to re-install the factory image to restore connections?

Hmm...I've been having some trouble with WiFi as well.
I was running CM10 and then installed the 4.3 factory image over that. That's where the problem started. Since then I've tried the 4.2 factory image, Ubuntu Touch, and I'm now back on CM10, but the issue remains that my WiFi seems to stop working even though the icon in the notification bar says that it's connected.

Well the weird thing is, is that every other app seems to work but that one where it just times out, I'm going to try just re-installing the update and see if that helps things.
Edit: After backing everything up I decided to re-install the 4.3 update and after downloading the Bank of America app it started up instantly, froze for a moment and allowed me to sign in.
I closed out of the app and tried again to check and after 3 attempts to sign in it worked each time, I think the re-installation did the trick.

HELP REQ - Stock Lollipop Note 3 N9005 - Random Reboots/Wifi-BT Clashes

Hi all,
Having a problem here.
Had my N9005 for about 18 months, never really had any problems with it - or rather, never really required anything of it which might manifest any problems.
I've always used Stock ROM's, soft-rooted.
Never triggered KNOX.
I'm currently running Stock Lollipop (latest Switzerland Open). Everything I'm about to elaborate is also the same using Stock Lollipop (latest UK Open).
I'm rooted on Lollipop using the method compiled by The TAMAS on XDADEV.
I root because my phone is work-critical, and so I use Titanium Backup to keep my data/calls/APN/SMS backed up and to make restoring easy, as well as to disable stock bloatware etc.
The problem may have pre-existed in pre-Lollipop ROM's, but the sequence of changes which caused it to be manifested included my need to update to Lollipop, about 5/6 months back.
THE PROBLEM - First and foremost, the damn phone reboots randomly. I become aware of it because it will vibrate for startup and play the Samsung startup tone and splash screen before booting to normal functionality. It can do this day or night, maybe 3-4 times a day. I have no error messages or warnings, it's done it while in my hand, while plugged in charging, while out and about, in the car, on wifi, on data. MOST times it reboots. SOME times it just shuts off and I don't realise it's off until I go to use it, or get a call on a second phone to ask why I'm not responding to calls or messages.
When it reboots itself, if I go to the Samsung Battery control panel pane and take a look at the battery chart it will show a gap which is longer than the time it took to reboot, and a shift in the battery meter level.
But, that's not the only possible symptom or problem with the phone.
I've noticed also that my WIFI does a lot of crapping out, or slowing to a crawl, even on my home AP. I've reset AP's, reset networks, reset the phone, forgotten and then reattached the AP in WiFi Settings. So I downloaded the Ookla Speedtest App, to see this issue in black and white, and sure enough, even though any other Android or iOS or Windows or OSX device in my place can connect via Wireless AP to my fibre connection and get great consistent throughput, the Note 3 can often appear crippled...
At it's best, it responds to ping quickly on the Speedtest app, and leaps up to the 30-40Mbps range with consistency for download, and up to 17-20Mbps for upload. This is the least I would expect it to do, my target standard.
At it's worst (which can be 'most of the time') it responds slowly to ping, and either struggles to get over 250Kbps download and maybe a crazy Meg or two for upload, consistently, a slow grind; or it may oscillate extremely wildly between slow and high speeds before eventually settling to unacceptably low transfer rates.
Up to press, I've been trying to chase these problems in isolation, believing them to be unconnected.
No success.
I've reflashed several times. I've Factory Reset. I've wiped data and cache. I've reinstalled and restored from Titanium. I've reinstalled and restored nothing but my SMS's and Call Logs. I've reduced my installed apps to bare minimums. I've tried it with a MicroSD installed, and without. I've bought another battery and replaced it. I've tried it in its case and without its case.
Then I started thinking that the problems were all the same thing, and stemming from the same root.
It suddenly occurred to me that my use of the phone changed significantly at the same time as I moved to Lollipop.
I need to be on Lollipop because apps and hardware that are critical to me are Lollipop dependent.
All at the same time, I began using a Moto360, a Bluetooth Receipt Printer and a Bluetooth Credit Card Reader, all of which are deficient in functionality or in some way hamstrung by not using Lollipop.
So I had gone from occasional BT user (maybe PlayerPro plus a BT link to headphones or my stereo occasionally; when needed, BT speakerphone in car) who usually turned BT off manually to preserve battery life, to a constantly connected BT user...
So I went back to Speedtest app, and tried to test the WIFI connection again. Sure enough, it was pitiful. Then I simply disabled BT on the N9005 and ran the test again, and had full 'through the roof' speed ratings.
I've tried this back and forth hundreds of times now, and it is predictable and established. BT is somehow crippling WIFI on my N9005.
I've tried running the phone on either wifi or data only, with BT off, and had a couple of days use at a time without any restarts. Put BT back on permanently, and the restarts resume within hours.
I'll be honest, I've even been cursing and swearing at my BT devices, because BT sometimes struggles to even maintain a continuous connection. I get vibrations all the time on my Moto360 indicating that the phone, which is on my person, has disconnected from the watch again, perhaps just for moments, sometimes for minutes, resulting in the watch eating battery life, trying to get reconnected.
I'm convinced now that all these things are related, and the problem lies somewhere in the interaction between BT and WIFI in my N9005.
It seems likely that I never noticed the problem before because I never required continuous BT connection before the point where I installed Lollipop.
Downgrading the ROM isn't an option. Leaving BT off isn't an option (nor should they have to be, on an 18 month old £600 smartphone).
Does anyone else have experience of this? Has anyone else had problems that they now suspect might be this same problem? Does anyone understand what's going on hardware/software wise, or have experience of a solution to these issues?
I'd appreciate your input urgently, even if only to affirm that I need to go to the inconvenience of temporarily buying another phone to replace this, while I send this away for a warranty repair.
Is this even a recognised hardware fault, or would I just get back an identical unit which is crippled from being able to perform as I expect it?
Please help.

T-mobile S7Edge stock, after Sept. 1st Security patch update, battery drain

I do not know whether it is coincidence, but I updated couple of days ago and all of sudden, starting this morning, the Android system is draining battery at alarming rate. It does appear that this happens only when I am on cellular network and not on wifi.
I have been off the charger about 2 hours and my battery is down to about 50% already.
The phone is running very hot. (I took it out of the case) It does not appear that turning off cellular data affects this at all.
Rebooted the phone couple of times to no avail, at this point, I am considering factory reset of the phone, but would like to get some opinions on what may be the cause.
I saw the thread on the "android system battery drain", but this does not appear to be related to what majority of people are reporting as this slows down the phone significantly enough that the phone is almost unusable at this point.
Cleared cache but don't think is helping. That said, when I was trying to get to the recovery, the system said "Installing update" and then "No command", before getting me to the cache, I am wondering whether the "update" did not clean up itself...
Thanks.
EDIT: Looks like the system cache clearing did help after all.... System appear to be working normally now. Will have to see..

Ok, well, back to the drawing board. The phone behaved ok all day long. Came home, I did 2 things, turn on wifi, and then turned on bluetooth to test out a headphone and then shut off the bluetooth. High battery drain again. Phone got hot and everything is VERY sluggish.
Shut down, cleared the cache again. Will see what happened.
Is there a way to go BACK to previous stock ROM WITHOUT factory reset?

Found out the issue, it was Oculus update which caused the issue. Looks like the bug caused the "Oculus Room" to install it self over and over again. I manually ran the Oculus home app, and it prompted me to update, which I did and it appear to have fixed the issue.

Flash your decice with version from sammobile.com

I have this exact same problem, posted about it yesterday but had no help.
I don't have Oculus on my phone though. But phone behaves for a most of the day, then does as the OP describes, still cant see why, but its only since the update.
