s7 will become unresponsive randomly for a short period then OK? and sluggish times. - Samsung Galaxy S7 Questions and Answers

hey guys, as the title says, my S7 is having issues. it has android 7, sprint. even after many updates from OTA, no change. I've already done a FULL factory reset. cache, everything. sometimes I'll use the phone, itll time off on it's own then I'll go to use it after a few seconds, or maybe minutes, and i can hit all the buttons, it wont wake up, give it a minute or 2 then it'll act normal. Then other times I'll be using it and it becomes So sluggish it locks up for a while..... again before and after a complete wipe/reset, made no difference before and after, and I even left it free of my apps for a while, no change. I have googled this issue and came up with nothing unfortunately. anybody else having it?

Frequent Reboots. Please Help

I have been using Cyanogen for at least the past year. In the past I have had trouble with things like random reboots, maps crashing during navigation, etc. Because of this I switched to just running the milestone releases for the past six months or so, and that has worked reasonably well. Its still way buggier than stock, but I put up with it for all of the nice features and what not.
Lately though reboots have become more and more frequent even though I hadn't changed anything. I had been running M9 for the past month with no real problems and then last night it decided to just go into a boot loop. I tried pulling the battery, clearing the cache, clearing dalvik, nothing worked. Eventually I just let the thing boot loop all night long and when I woke up it was finally booted.
Then this afternoon it did it again for a short period of time (3 or 4 minutes). When it came out I decided to download the newest, M10. It took several tries to actually flash it because the phone would reboot iself while in the middle of the wipe, or the flash, etc. But I started the wipe/flash process from the beginning every time to make sure I had a clean flash and eventually I got all the way through. But now it is at a point where it will boot, sit there for 2 or 3 minutes (I don't even touch it), and then reboot.
I'm hoping someone can help. I'm holding onto my unlimited data for dear life... I don't want to have to get a new phone. But re-flashing doesn't fix the problem so I really don't know what to do.

I don't know why your having such an issue with cm. Which is odd because I'm running a rom that's CM based and works fine. I'd say maybe try another rom if for nothing other than to see if CM is truly the issue.
I praise you for having the unlimited data still, I wish I would be been smarter and kept mine because there are months where I'm a little too close to that sad but lack of data with 2gb
And my hometown is Syracuse NY as I see your city is there. I miss the cuse but not the loudness of the city

Pull a logcat or use a tool like https://play.google.com/store/apps/details?id=com.tortel.syslog to do this for you. then after the phone reboots itself, run syslog and examine the last_kmsg and logcat to see what the obvious errors/issues are.
I too have noticed google maps crashing, camera unable to connect, random reboots, file system errors, sluggishness, etc more lately with my G3 too. Wonder if some aspects of the hardware are failing...

You mean freeze the stock camera and use the Google camera instead?
Yea, when the camera is broken, neither app can connect until phone rebooted. Already tried many a time.

These symptoms could indicate a sticky power button. Try knocking it lightly against the corner of a table to jar whatever is making it stick loose.
It doesn't sound software related, especially since it rebooted while in recovery. If you hold the power button down long enough in recovery it will reboot, which makes me think you just have a sticky power button. It's happened to me before.

I think you might be right. Even when it is up and running, I have been noticing lately that I get the power menu popping up sometimes when I wasn't even touching the power button. So last night when it was in one of its constant boot loop fits I took it apart a bit (took the back off, took out the battery sim and sd, and unscrewed the shell) and blew some compressed air all around the power button. It had been rebooting for about an hour at that point and then as soon as I put it back together it came up on the first try. So far so good.

Phone randomly corrupted somehow, need help.

Hello people, first off lemme say I'm not necessarily new to this forum, I for sure have used it a hell of a lot in the past and I know roughly what goes on around here, I've recently created my account in order for me to actually be able to be able to plead for the amazing help the XDA is known for.
Anyway, long story short, I don't know what the hell happened, but allow me to start from the beginning. I went on a camping weekend with my OPO, phone worked flawlessly all weekend and lasted the whole time, everything was fab, went back to a mates house and asked if I could borrow his phone charger (He has a Lumia 625 incase anyone was wondering), we then went out shooting and I left the phone there for a few hours to charge. Came back to it and it was fully charged, but had turned itself off? Because it was on the power off charge screen when I came back to it, and was on lock when I left it, nobody touched it in that time. I took it off charge, powered the phone up and it must of boot looped about 3 times? Eventually it got into CM but there was no lockscreen, went straight to the homescreen. This is where it went nasty, the capacitive keys outright weren't responding, the device wasn't slow as such, nor was the CPU running hot or doing anything intensive (I have CPU load display enabled), but the date was set to Jan 1970, and the phone couldn't pull a signal at all. WiFi outright wouldn't switch on either. So I tried rebooting it a few times, to no prevail. For some reason, I accidentally tapped Bluetooth in the quick settings panel, the phone crashed and rebooted, and wouldn't stay on for more then 3 seconds? Before crashing and rebooting. I've since gone into recovery and tried a factory reset, cleared cache and media too, but to no luck. Phone still doesn't stay on for more than about 3 seconds once it actually gets into CM (The welcome to CM screen, it crashes 3 sec immediately after boot).
I have no idea what I'm supposed to do, can anyone try shed some light on this? Much help would be appreciated and I sincerely APOLOGISE for the wall of text. Many thanks.
^Dat wall of text doe (sorry about that)

Thank you man for the pointer, I'll give it a go. And yeah sorry for the wall.
No worries, I hope it works for you.

I am having the same issue since last night. Put my phone to charge and when I picked it up it stayed on for about a minute unable to connect to Wifi or cellular signal. Then it went to a crazy boot loop. Wiped cache, media and at the end data. Now it boots and it stays on for a few seconds and reboots. I will try the solution when I get home tonight but I was just curious if it worked for you.

HTC One M8 reset itself?!

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.

Phone won't stop with the vibrations. Dear god.

Was wondering if anyone has run into this problem?
The phone was fine, rooted and everything, for a month give or take. Then all of a sudden, today, it started acting weird.
It was fine in the morning and everything, was able to use wifi, check emails, and stuff.
Then BAM, I tried to make a call, it didn't go through for the first 20 seconds or so. Then connected and a message kept popping up saying Phone is stopped or something during and after the call.
So, I restarted the phone. It restarted fine and everything, got past the 2 Samsung screens. Then hit the T-Mobile screen. and has been stuck on the T-Mobile screen for ~30 minutes now and just keeps vibrating.
It's getting quite hot, both front and back.
Any advice? Stupid Samsung making this a closed system so can't pull out the battery.
Can't even turn the phone off, only able to get to Download screen.
Weird problem.
Is there any way to pull the data and stuff off the phone at this point?
I'm thinking of going the factory reset route and do that to see what happens and see if it will fix the problem. It would probably not retain root am I correct and I would have to re-root again?
I could get into download mode and recovery fine.
You're just in a bootloop. Try holding down power and home.
Sent from my Samsung SM-G930T using XDA Labs
That happened to me like clockwork until I found these fixes here. "Everything has stopped" and then wouldn't not from a restart.
http://forum.xda-developers.com/ver...-to-notes-root-install-xposed-unroot-t3411039
I refreshed probably 4 times thinking something was wrong with my phone until I flashed those fix zips in that thread. Solid ever since.

Abnormal reboots, every day..

Have any of you experienced any abnormal reboots on the u11? Suddenly my phone either freezes or the screen goes black and then it turns off. It's terribly annoying and can't find anything about it online. I'm not quite certain but I think it started after the last update.
are you stock?
have you attempted a factory reset?
try running an RUU?
Tough to provide any insight without outlining what you've done to attempt to fix it.
try factory reset and wipe cache partition. Please back up everything before you do it.
I'm quite sure that I have allready factory resrt, but will try again! I am stock and what is RUU?
I think i have the same problem. My phone suddenly shuts off and i have to
use the down volumerocker plus the on key for 12-15 seconds and then
it starts up again so i can do a reboot. This have happened once a week.
Maybe it´s due to that i have been watching Netflix for a couple of hours.
Both times happened after watching Netflix.
But this is the first phone i have had that can´t handle watching
movies for a while. Can there be a failsafe built in to the 835 processor?
So it won´t overheat or something?
/Z
Same here since arround 2 months.
Any updates on that issue? Does the hard reset solve the problem.
It happens also twice a week
