So over the last few days my phone seems to have settled into some sort of weird pattern with reboots. Although there are outliers, in general it always seems to reboot between 19-24h of uptime and nearly always at like 45 or 50 mins past the hour. It's the most bizarre thing in the world and why I think there's some funky software doing it. I don't have true random reboots, but I can't figure out what it is that is doing this. Very odd.
In all cases my phone is sitting with the screen off (I've NEVER had a reboot while using the phone/screen on) but it doesn't matter what radios are on, WiFi, BT, GPS (can be off or on).
Last time I ran "CatLog" a logging app from Market and had it write to SD logs and a reboot happened but it only by default writes every 200 lines so the last line in the file was probably not the last line in the log. I'm going to try again later and set it to write every line or few lines so I can see the last entry in the log before a reboot. Might shine some light on it.
Just find it very strange since it's a very stable and capable phone for about 18hrs and then it just craps on itself. Very strange.
finally. I too just think it is some weird software or driver bug because I was running EB 1.0.4 FINE for like 3-4 days and loving it... then it started resetting almost hourly. I didn't install any other apps past my initial normal set of apps.
Even CM7, seems like it is fine for a few days, then gets crazy. As long as I put a new nightly rom on it every day, it's good.
I didn't have any issues with stock though and didn't seem to have issues with CM7 for a while until lately.
The leaked GB rom causes lockups immediately out of the gate seemed hourly.
I use CM7 as my main daily driver now but I think you are on to something. We are talking about the Screen of Death right? I don't think mine ever reboots, but gets stuck at the lockscreen where the the display comes up, swiping to unlock vibrates then the phone but doesn't change screens to desktop. The buttons and click/drag widgets work even though you are looking the lockscreen.
I've never had my phone powered off in my pocket or noticed it "rebooting". Mine just has the SoD that seems to follow your pattern idea. They may be related. Stock roms may reset once it locks up, where CM7 just keeps running in its locked state.
I have a really strong sneaking suspicion that every G2X reboots but not everyone notices. Also if you naturually turn your phone off once a day or so you won't notice it perhaps or even a few days. The phone reboots pretty fast and the only way I've been noticing (except the times I see/hear it happen) is I have an uptime widget on my homescreen so it's obvious.
Same thing happened with my Droid Incredible btw...when it first came out there were all kind of random reboot issues. After a software update I would run that phone hard for 30-45 DAYS straight without a reboot.
It's annoying but I think it's just a matter of time before the G2X is the same.
I just hope that update gets here sooner than later.

I dunno. The tmobile jingle is pretty loud and I never hear it. CM7 has a silent one so possibly there but I dunno.
I use my phone pretty often and never had the suspicious that it reboots. My phone stays very cool during my usage compared to my nexus and other phones
My uptime was 4 hours since I reset it last. I'll monitor it with results. It'll be hard not to flash but I'll keep track and see how far I can keep it online.
i have not had any reboots or waking up to a dead phone ....with the only fix is a battery pull.... ever since I started.
1) my over night charging / long term charging to 100%... only on the LG charger that it came with. Only short term...maybe. less than an hour and not to a 100% charge on a non LG charger (car charger etc...)
2) I restart my G2x every morning when I take it off the LG charger..(after I take it off..I did it once while on the charger and had an issue... (there is definitely an issue related to when it charges to/ around 100% charge)
Just my 2 cents.
Pattern to my reboots - do yours have a pattern?
Hold Power and volume up simultaneously for about 10 seconds.
I've had my phone since Friday, but the only time I had the rebooting problem was this past Saturday when it rebooted four times within 15 minutes or so. Before the rebooting began, the phone had slowed down to a crawl, so I went ahead and rebooted it. After that, I sat it down and watched it reboot a few times on its own. Luckily my iPhone 4 owning co-worker was completely unaware of this issue since we tease and bicker with each other every day over Android and iOS .

I can guarantee that mine don't reboot. I've had it up fire days, checked the up time and play with it constantly.if it rebooted in the middle of the night I would hear it or the uptime would be close to zero in the morning..
I have a way stable phone.running stock, rooted with bloat removed.. I love this damn stable phone.

Everything other than smart share, tegra zone and qik. Of course have nova and need for speed also.
Oh also have car home froze..
Maybe jumping the gun here but I tried to let mine go as long as it could without resetting it. I kept tabs on it and it was running awesome the entire time (#33 CM7).
Last time I noticed my phone on was like 17:33:xx hours. I had like 44% battery left. Next thing I know the phone is off. I tried turning it on and a battery icon flashed and turned back off.
What I am thinking is that perhaps the faulty battery driver is telling the phone that the battery is dead and preventing it from booting up. We were talking in another thread and I said something that really makes sense: If the battery driver tells the OS that there is 0% battery then it will just reboot. The battery itself may have a 50% charge left. That would explain the random reboots too (the battery driver telling the phone there is 1% left and cutting power). Maybe a hard reset semi-corrects the problem but eventually resets again due to false information.
My weirdness/powered off occurred right around 18hours. The phone could have just died too.
Almost need a Voltmeter so someone can test the battery (or however it can be tested).

Yes I know the battery driver is part of the problem as can be seen on CM7 builds but what's odd is my time varies so for a long time it would reboot every 17-20 hours, now all of a sudden it goes to 36 hours before it usually reboots. Looking at logs it doesn't appear to throw any major errors before a reboot which implies that it's a a kernel panic or low-level fault. At this point I've given up on trying to find the issue since it's been repeated over and over that T-Mo and LG are releasing an update. Might as well enjoy the phone and wait for that to come out
Amen. Just keep flashing CM nightlies and you'll never worry about it.
Anyone come across this? I put it on standby last night after reading a bit of my book on it, and it had around 50% power remaining. This morning, it was totally unresponsive; pressing the power button does nothing at all. I've charged it for 12 hours in the meantime.
I've done the following all with and without the power attached:
- Pressed and held power for 15 seconds through to a minute
- Pressed and held volume up with power to attempt to get into recovery for up to a minute
- Pressed and held volume down with powerfor up to a minute
- Pressed and held power while touching screen (read that one off another forum)
I guess potentially it could be on and in a crashed state and unresponsive to the power, so maybe in a weeks time when it runs out of juice, I'll be able to charge it and power it back up, but in the meantime, I'd welcome suggestions.
A few weeks ago I updated it to the official ICS build that was released, but did the update myself rather than using KIES, as KIES didn't even recognise my Tab's firmware original version. It's been absolutely fine before the update, and since. I only mention it because I've read about the Samsung build of ICS being prone to self bricking itself, but I couldn't determine what the symptoms of this vulnerability were.
Thanks for any help offered,
Will
did you try connecting USB cable and plugging it into your PC? did u get any activity? can ADB recognize your tab?
I think your tab just ran out of juice and the battery's protection circuit has kicked in. Try taking it to an electronic shop and plugging in different chargers preferably one with an output more than 2.1 amps to kickstart the charging. Plug it in and wait till the charging animation starts.

Had the same problem while on holidays. Once the battery goes below a certain level, you won't be able to charge it through USB any more. Instead you need to use the wall charger.
I think it's bad enough that the 7.7 doesn't have a micro USB port, but things like that are just stupid and Samsung made a big mistake here. It don't think it's the same with the newer tablets though. It's also not possible to just buy cables or chargers for this strange Samsung port, so when you forget your wall charger at home at some point you won't be able to use your tablet any more.
As long as you charge with the USB cable early enough, you can avoid it though.
A few months ago I experienced the same thing, the Tab just wouldn't turn on anymore.
I tried all there is without any luck.
Contacted amazon and they replaced it with a new one in less than 48 hours.
So far not Problems with the new device.
I have the P6800 and this morning I took it off charge. Put it into standby and only used it for about 20 mins then left in standby all day. It had about 95% remaining when I did so.
Picked it up this evening and the lower left area of the screen was warm and it would not switch on. Didn't think of the ADB idea but will try this next time but I had to reset it and when it powered on tonight after the reset, it was down to 15%. Within about 2 mins of checking stuff it was down to 3%.
Something is running when it is in standby but as I can't switch it on I can't check with BetterBatteryStats or CPUState to know what is wrong.
It does this every day. I am tempted to do a factory reset and reinstall only limited software.
Dave...
I see this thread is a little old but this has just happened to my P6810 too. A pity nobody reported back what the end result was.
My device had at least 95% battery last night but today I can't get it to respond at all, I've tried the wall charger and still nothing.
Anything else someone could suggest for me?
Edit. I tried getting anything from it connected to my PC but it couldn't find a device there. However I then tried it on the wall charger again and now get a blue battery icon, quite big, with a five step animation indicating that it is charging.
No idea how it went flat as the battery on this lasts a long time assuming the screen isn't on. When it boots properly I'll have a look at what the most recent apps I installed were as it has only done this once. Before this it has been perfect for the three weeks I've had it.

This is the infamous Sleep-Of-Death issue that is randomly experienced by myself and other users here, usually happens when WiFi bugs out due to weak signal

hhmmm, interesting.
I was having trouble with wifi just before this happened. Both my GS2 and this have been claiming to connect to my wifi but aren't actually getting an IP address from it.
I can't remember if it was last night or the night before but I manually set an IP address, the signal strength is fine as my abode isn't very big.
After it has recharged I'll have a poke and see what I can find, thanks for the reply.
So my device seems to be working fine again. It had gone SO flat that the date and time were incorrect!
After I could power it on I had a look at Better Battery Stats and nothing looked wrong so I have no idea what happened. None of the apps I'd installed the day before it played up had long wakelocks and weren't running when I turned it off.
For reference they were:
My Tracks
MyTrails
Google Earth
AndSMB
I'd turned both of the GPS tracking devices off before I turned it off for the night.
It hasn't played up since but it hasn't been long so I'll see what happens.
Yeah, the sleep of death is incredibly annoying. Honestly, the GTab 7.7 is a **** device. Samsung made way too many mistakes and won't do anything to fix it.
A similar thing happens to me every once in awhile. The way i check to make sure everything alright is to see if it boots into download mode. I just leave it plugged in for a couple hours and it eventually comes back on.

this is why my 7.7 is the last tablet/phone from Samsung i'll never trust them they are just bombarding the market with new devices and leaving the old ones to dust
^thats what I thought too but that gs4 is really tempting. I've heard worse about HTC in that regard anyways so that why I'm not going with the one.
Finally.. i bought Sony xperia Z.
I'll sell my galaxy tab 7.7. I.m very disappointed with samsung.

Unbelievable! ... this trick still works ... thank you very much for you help ...
^^ yo, this 'trickle charge' trick did NOT work on my (long) dead P6800... any other suggestions??
Quite strange because my Samsung GT-P6800 tablet was fully charged, it went completely blank dark as if it was off. To my amazement, SMS keeps dropping and calls kept coming in. Yet it is still as blank as though the tab was off. I pressed the power button and the volume up bottom for it to reboot. It rebooted without the screen coming up. It has been blank for two days now. What could be the cause? And what possible solution can be given?
Hi, i have an s6 (non edge), i do have it insured so not sure if i would be best trying to get it swapped or see how it goes?
I have had no problems up to now, been using it most of the day fine, the last time i looked at my phone was probaby about 30 mins before this happened and it had about 75% battery.
before i took my phone out my pocket and it was completely off, i kept pushing the power button in and getting no response at all, i plugged the phone into the mains and nothing happened, no charge light etc..
So i just left it connected to the mains with nothing happening for about 15 mins, then out the blue i pressed the power button in again and it come on, at it was starting i noticed it said android is updating an app (as it does when you have just installed a new fw) but this was only for 1 app by the looks, i hadn't installed anything new i can think of, not sure if thats related or not important?
Anyway my phone seems ok at the moment but now im not sure if i should just take it back the shop and get it changed seems i have it insured anyway, the phone is around 3 months old now.
Sorry, i am just editing this, i have just remembered one main point which i forgot i done earlier when reading that it can help your phone, i did go into dev options and i changed the 'limit background processes to 4' as i read this can help it, not sure if this was a bad idea?
Any advice?
Thanks

Possibly a defective battery.
The other day, my phone died midway through a call. When I tried to turn it on, the 0% sign showed up meaning it was completely dead. I had to urgently make a call so 30 mins later, I held the power button again, turned it on, and the phone went to the white HTC screen and then turned off. I finally got home and connected to my phone to my charger after. I let it charge for a bit then turned it on. I knew something was wrong when my phone was hung on the red Verizon boot logo for a while. Minutes later, it went past the Verizon logo and a pop-up appeared that said optimizing app 1 of 44. I thought this was odd because I already got the MM update about 2 weeks ago and since it updated, I never saw that message ever until now.
Once my phone gets past that and finally boots to the homescreen, I realize that a lot of things have gone wrong. First, I got signed out out of all my accounts (Whatsapp, Spotify, Instagram, Facebook, etc). On top of that, my call history was cleared, all my text messages were cleared, and all my contacts that were saved on my phone storage were gone. In addition, I also had to re-update a lot of apps including the HTC ones that you have to upon the MM update. Finally prior to those whole thing happening I had 10.7gb of free space. After this episode, I lost exactly 1 gb of storage and only have 9.7gb free.
I don't understand what could have caused this or why I lost all this data on my phone. Moreover, it doesn't seem like anything was deleted but my phone is just not reading anything that was already there.
mine just did this exact same thing after shutting off from a drained battery. It's like the data partition or whatever got wiped. Right now trying to log back in to everything and set EVERYTHING back up again. This sucks.

i came here for the same thing. mine happened around the same time. only thing i can add here is that my storage is almost maxed out on the phone. makes me wonder if that had something to do with it. but then this happened to two other people around the same time. very weird.
The exact same thing happened AGAIN! I was at the gym listening to music and texting some friends while my battery was at 15%. Went from 15% to 10% in a matter of mere minutes and then from 10% just shut off. Couldn't charge it until I got home so I just kept it in my pocket. Got home about an hour later, put it to charge and then turned it on when battery hit about 10%. Same damn thing, got stuck on the Verizon boot logo and then the dreaded Optimizing Apps message showed up. Once it finished, I was logged out of all accounts, updates to system apps were gone, and widgets/BlinkFeed were gone/reset. And just like last time, suddenly 1GB of storage was gone.
Literally un-freaking-believable. I dreaded that it would happen when my phone shut off and yep, my fears were right. Going to do a factory reset once I backup everything. From there, I am debating whether to replace the battery or replace my phone. While it sucks that it happened to you guys as well, I am somewhat glad its an HTC issue and not just an issue with my personal phone.
Same thing happened to me at 40%
This was recently brought up in the viper rom thread, could be of help.

Your battery needs to be reset. Hold down POWER + VOLUME (can't remember if it was up or down. takes about 10 seconds)and let it keep resetting and keep holding it for 3 minutes. then let go.
It'll fix your battery so that it drains to 0 instead of 13, but it doesn't fix the weird pseudo-reset problem. It's a known issue and many people are struggling with it. My advice is to set EXTREME POWER SAVER to auto-on at 10%, and if you ever see it that low, just turn it off yourself until you get a chance to charge it.

Same thing has been happening to me since the MM upgrade. Before that I had NO issues with my battery so I find it hard to believe that my battery is the problem.
After the third time of this happening I finally decided to to a factory reset. This did not help, phone continues to die anywhere between 15% - 30% and revert some of my settings back to stock.
This is driving me insane as I rely on this phone for personal and work use.
Decided to call HTC support today, I did not expect a solution but wanted to make sure it was reported. Of course they had no idea and claimed to have never heard of this issue.
I am guessing that since the M8 is over two years old we wont be seeing and fix pushed out for this issue. I really like my phone and dont want to upgrade at this time.
Finally somewhere where people are actually having the same issue. I've tried factory resetting the phone, doing a fresh install of the OS (with firmware recovery tool) all with no avail. I note lose all my settings and app configurations every time the phone dies, shuts down or restarts. I hope there's a fix, otherwise it looks like a custom rom is the only way.
Has anyone tried wiping the dalvic cache? I can't get into the recovery on my phone so I can't try it, but heard I it might help.
Had the same issue last week
I was at about 20%, phone shut down. I plugged it in to charge, went to boot it up, and it got stuck on the Verizon bootup screen.
I waited a while and did a hard reset, and it came back on, but was completely wiped. So I had the same problem, which is a real pain, because I use the GOOD app for work, and each time that re-installs I have to get a new PIN. And I have had to re-install the app a few times in the past month for a variety of reasons...

I feel your pain. I use Mobilepass for work and every time my phone resets it deletes my token and I have to request a new one.....
Here is what I did two days ago that seems so far to be working for me. I calibrated the battery. I have tried this in the past but could never get the calibration to work properly. Each time I tried I had the phone plugged into the charger. This time I didnt and the phone went through the battery calibration process like it is supposed to.
Since I have done this my phone will stay on until it gets to 8 or 9% and then shut down but when i charge and turn back on all of my setting are still in place.
To calibrate the battery I held the up volume, down volume and power button (all 3) for a full 2 minutes without the phone being plugged in. During this time the phone will start and get to the HTC splash screen then shut back off, start again to the HTC splash screen then shut off, repeat, repeat, repeat.... after 2 minutes release the buttons and let the phone boot up, plug it in and let it charge to 100%.
I hope this helps,
This happened to me today. I let the battery get a little lower than usual last night, around 13% before shutting it down and plugging it in for the night. Turned it on this morning and it booted up normally. Didn't lose any apps or data, but every time I did something on the phone it gave me those little hints like its a brand new phone. I went to settings and it says it was factory reset at 6:46 a.m. this morning (about the time I turned it on).

Did it reset your ringtone and notification tone settings? Thats what it always has done to me.
I would just like to say that the same thing happens to me as well on my HTC one m8. Battery suddenly dies, now even at 25%, even after a calibration which is just a temporary solution, and when I turn the phone again, SwiftKey settings erased, everything went to stock, messages and contacts are preserved, but the apps start updating itself even though they are not allowed to and I have to manually set a lot of things. It is a total confusion and I literally can't believe HTC allows themselves to not issuing a fix for this disaster.
Was it cold?
Same issue. With mine it seems to be when it gets cold. I was skiing today in 20F but inside my pocket this really shouldn't be an issue. It has turned itself off and refused to restart several times when it has been used to take pictures in cool weather (I live in western OR, it doesn't get COLD, by cool I mean <35F but >20F, usually > 25F). This is the third time it has totally screwed up the phone when it has happened. On another occurrence it reset under normal conditions too. I'm getting pretty sick of it as it is quite a process to get all my VPN tokens reset, get all the apps back etc. Of course it waited until the warranty was out to start acting up.
This time is especially bad, the phone will not restart properly and important processes just constantly flag as stopping so that I can't even get past the initialization screen. It looks like I will have to do a full factory reset. If anyone from HTC is reading...Not acceptable and I won't be buying another phone from you.
Unfortunately I've reached the point where I wouldn't be surprised if it is a programmed planned obsolescence function, but whether or not, this is really annoying behavior.
Sorry to hash up an old thread but I put up with this crap for 5 months before I finally punched and broke the screen out of rage during an important business tech support call when I was at the clients location trying to service their security equipment, it was so embarrassing having to tell them I have to come back especially since it was a remote location.
Mine would wipe contacts, texts etc regularly. I ended up installing Super backup or something and saving my backups on google drive and just restoring everything everytime it happened.
I decided to fix up the phone and replace the battery, broken charging port and smashed screen and unlock bootloader and root but flashing superSU didnt work, got stuck in a bootloop. Anyways through all this I wiped all the caches (including Dalvik cache) flashed the correct stock rom and did the battery calibration and that seemed to have solved the random shutdown and memory leaking issue.....but I guess I wont know for a while.
I have a HTC One 610, and like every once in a while it well automatically reset it self whenever I am in the middle of a text message, on facebook, or even sending an email on phone. Its getting annoying when my cell reset its self.
what needs to be done to it? and should I do.

try a factory reset
I know its old but people are having the same issue still so I'm gonna paste this everywhere i find this problem.
There is a Modified stock rom named "Android_Revolution_HD-One_M8_53.1" and its almost the stock M8 without bloatware and so much more stability improvements. So hear me out and flash it with a custom recovery (i did it with twrp) and it seems to be working fine so far. Give it a go before you trash your -still so good- phone to the open seas.
Well, this issue is still happening. my phone has been doing the same for about a week now. ive made several attempts to reset the battery and had to reinstall back ups every time its happened also. the only difference i think now is that its happening at 90% instead of the usual 15%. ive been following instructions to hold volume up, down, and power (with the phone off) for about 2 minutes and then letting go. i have my extreme power saver set to come on at 15% but Im not even getting that low before it shuts off and resets. i have however noticed that recently that if you plug the phone on charge after it first dies you can avoid the phone resetting.. this may be a fluke but its allowing me to deal with the battery problem now without the loss of my data, contacts, etc.
This is exactly the reason why HTC One M8 is the last HTC phone I will ever purchase. Imagine the hassle of phone factory resetting on its own. Horrible.
I have a P900 that was left in a drawer for 2 or 3 years, never getting charged even once in all that time. Turning it on, I immediately realized something was wrong because it took forever to boot. The lock screen was so slow that the entire machine locked up for a few seconds, scrolling between pages on the launcher stuttered hard or locked up and everything else with the machine was generally the same. The web browser is unusable, even typing in a URL locks things up. The device is unusable.
So I thought the battery was obviously damaged, even charged at 100% it would be flat for sitting for maybe 2 hours with the screen off. I tried several cycles of charging to 100% then discharging and back up, but nothing seems to help. I don't have much money so I took at stab in the dark and got a cheap battery from ebay and it didn't help. I don't know if this battery is new, but it does seem to hold a charge like the device did when it was new but it's just still so slow that you can't use it.
However, one thing that I've noticed is that apps that don't touch the storage seem to work OK. I have a Spectrum TV app that once it starts up seems to be okay, but not great. Netflix seems to be okay as well after starting up. They both stutter a bit and rarely freeze. I don't know if this is relevant at all.
I'm at a loss of what else could be damaged or how to fix this. I'm in the process of cycling this new battery up and down, though I don't know if this would actually help. I just don't know how to diagnose this problem.
Okay, the problem was the battery, it just took a few hours of charging. I guess now that it can see it has a fully functioning battery that it's running as it should now. Android really should give you an error message about that instead of just slowing the whole thing down to a crawl, leaving you scratching your head.
This strange thing happened to me also.
I was given a tablet that was not in use couple of years. It takes about one hour on charger to start booting at all, I was thinking that it don't working at all.
Then it sits on Samsung Note Pro logo about 15 minutes, then logo changed to Samsung and it took about 15 more minutes to boot in home screen.
Then i realized that it's very slow and unresponsive, I charged it to full and reset, but it's remain the same, very sluggish.
Tried everything, reset it couple of times, flash rom with Odin, nothing helped.
After couple of charge-discharge cycles it starts to work like new!
I would never have thought that the battery could do that, but there it is.
