Does your SGS ever turn itself off randomly?

Since I have got it (2 weeks ago) i have picked up my phone make a call, and on about 7-8 occasions, have noticed that the phone is turned off, and I can't get it to turn on. The only solution is to take out the battery and put it back in. Has anyone else experienced this. I have updated to JH2 firmware, but it still happens. I even got a new battery for the phone (Bell employee let me swap with another phone that was going back to samsung for gps issues), but the problem still happens once in awhile (like every 2 days, sometimes more sometimes less). Anyone have any ideas? thanks

More likely that it just "freezes" and you can't get it to react, then the solution is to take out and back in the battery - Sounds like a defective unit to me.

i think your phone was unable to wake? i have that problem previously where i can still call through my phone (using another phone) but there's no vibration / notifications of sorts.
i then realized i've been playing with SetCPU of late, long story short, i uninstalled the application, rebooted and all is fine since then.
good luck!
if it still persists, i'd do a reflash, wipe every bit of data available + formatting my SD cards. lol.

So..are you saying that the phone is actually still 'on'...just the screen is not turning on?

yeee sort of. lol. but why it's unable to answer, yet able to receive calls. i have no idea. same goes for any kind of notification that wakes your screen (SMS, calls, alarm, etc.)

Next time it happens, i'll try calling the phone to see what happens...I dont wanna return it because I have a 'rare' phone that seems to have good gps and can enter recovery mode.

you should check bell to see if there working and have recovery mode i got my just recently the newer shipments are hopefully all working with recovery mode and good gps

Did you install any Lockscreen app or something similar? I´ve read about another guy who had similar problems with a not waking up device. And it was a lockscreen app that caused this.

Yeah, I agree with everyone. I had SetCPU on my device and it would shut off a bunch of times per day. After I unintalled it everything worked fine. Another trick you can try is when the phone "freezes" try to hold down the home key. You sould still get the task manager box.

My first SGS did this a lot. My second and third SGS have not done this. Conclusion: faulty.

Yep...
I'm with mine for more than three weeks now, and I've never managed to cause it to freeze/shut down. although yours considerable rare, You'd rather have a working device I presume...

No, i haven't installed any apps like that. Like i said, GPS works 'ok' on this phone and it enters recovery mode. Thats why I would hope its a software thing and can be fixed. I will go back to get an exchange today ONLY if they let me try it out 1st (recovery mode).

I've had this happen twice, both times I was charging the phone with the screen locked and the cable was accidentally violently jerked out, after that my phone wouldn't turn back on without a battery pull. It has not happened of it's own accord though.

Note 4 Randomly Turned Off Won't Turn On Anymore

Hi everyone, after trying everything I could to fix this phone I don't know what to do anymore so I'm here asking for other options.
So the story is, I was just using my phone as I usually would that day and it just randomly turned off and won't turn back on anymore.
(it randomly turned off before a couple of times but it would always turn back on)
- It won't go into recovery mode or any other of the 'modes' (I tried all the different combinations of pressing the keys).
- It's not a battery issue as I've tried my battery on my brother's phone (he has a Note 4 too) and it worked fine and I tried his battery on mine and it wouldn't work.
- I tried the 'drain' method (removing the battery and holding the power button for a minute or more).
- I tried using multiple cables to charge my phone nothing worked.
I didn't drop my phone, wet it, root it or anything and it was working fine the day it happened until it just powered off by itself. When I plug it in my laptop it would make
a sound indicating I've plugged something in but nothing happens. It was version 5.1.1 model SM-N910F.
TLDR; Is there a way to somehow recover the files in the internal phone memory?

This is happening to me as well, also started in February. I'm suspecting a hardware issue. Tried it ALL but rooting. In the past 30 minutes my phone has booted and rebooted itself till it died. If someone can confirm it is a hardware issue. Maybe it's time to unite and get it fixed for free. ~Tamarnouche

Recovering data from a brain dead phone may not be possible, as it probably need some internal component replacement which may erase the data(Mostly). Have u tried connecting it to pc? Better give it to service immediately. Good Luck.

My phone has done exactly the same thing, happened in February too, initially it did the random freeze then started to reboot itself, went back to stock software and full wipe but no improvement; now it will only boot if I leave the battery out for a prolonged period, otherwise it doesn't respond to the power button at all.
I occasionally see MMC Read Fail on boot but not all the time so presumably the internal memory has a bad contact or is failing.
Can it be replaced?

I have the same problem with my Note 3. Only if I keep the battery out for a long (over 24 hours) time I can see the boot logo. So if you find a solution to this kindly don't forget to tag me, will really appreciate it.

I was wondering..
I came across this Forum group since I was looking for boot problems with my SM-N910T3
I hope flashing pit will resolve this..
I recently started to have some low level issue and was hoping it was partition/boot related and not hardware.
Randomly phone boot directly into Download mode with error;
ddi: mmc_read failed
Often I have to pull battery and hold down /power / home for 10 sec to boot up again.
Thanks

Freezing! Rebooting?

Hey guys
My edge has frozen 3 times already to the point I have to reboot holding the 3 buttons.
Anyone else have this issue?

My screen went black, had to hold the volume down and power until it rebooted. I've only had this phone for 4 hours.

Nope guys, mine running like a dream and I'm Def a power user. I'd try a couple back to back factory resets.if you still have issues, take it back.

Got the same issue. And factory reseting didn't do anything. I also tried to reset using the 3 buttons but it just says downloading for more than an hour! I really don't want to send it back and go trough the whole hassle. I just want a fix. I got this phone yesterday and I can't enjoy it... it only freezes when on standby for some time. The only way I can get it to work is by using the 3 buttons just like they guy above...

The downloading screen is just a bootloader screen for flashing rom while odin. If you isn't flashing rom, you don't need to wait for it since the phone is doing nothing.

Got a reboot once on PAW FW. Nothing after.

Yep had one yesterday after using bbc iplayer, tried to go back into iplayer from multitasking and it froze then went black . .used the volume and power for 7 secs and everything came back on . .
Hoping this is just software. .
Mine is UK version and got it on the 8th . .
Read that the S6 had similar problems

Anyone have a fix for this or do I need to take it back to Verizon? I'm in the US and have the same issue. It has happened to me multiple times.
I get automatic reboots as well as full screen lockup for 7-10 minutes where it reboots itself. Both seem to occur when I'm trying to do something immediately after doing something else. Examples are when I hit send on a text/tweet and then pull down the task bar while it's in the process of sending the text/tweet or when rotating screen to look at a picture in landscape mode in Facebook and immediately tapping the center of the screen to get rid of the text on the screen.
This has now happened every day I've had the phone (Friday, Saturday, and now Sunday). It's getting quite old. Any help would be appreciated before I take my phone back to Verizon tomorrow.

I haven't had any freezing, but I did have my first random reboot after 4 days of ownership while listening to music with it plugged into an aux cable..

Same.

i experienced the same issue, freezing up, i reset my phone and someone told to me to install an optimizer to help my phone by freezing up

I got the phone for 2 weeks now, yesterday my volume down and power button is unresponsive, press the power button for a few seconds but it wont respond. I have to hold volume and power buttons and press until a few more seconds and ir restarts, after rebooting it works ok.

Anyone have an update to this thread? Has anyone gotten a fix for this? Or should I just send my phone back and get another? Thanks for any help.

Just had another freeze and shutdown . .doesn't reboot but requires me too use power on and volume keys for 7 seconds to restart phone. .really hope its a software problem ..seems to happen on multi tasking

same for Galaxy S6
i have the Galaxy S6 and i have the same probleme, my phone keep freezing and some time rebooting, i try the safe more but still freezing, i delete the new installed app with no luck.
some other wesite say this is an apps crash that make the phone freezing, but i don't know.

Don't worry, Samsung will fix this with an update. Only had 1 reboot and it was on PAW fw.. now that I'm on pb4 it haven't happened once.

I have a verizon S7 edge, and have had multiple reboots on the phone, with no consistent pattern. It has done it while sitting on the bed untouched/unused. It remounts the SD card every time this happens. I'm really stunned there is no word from Samsung about this issue

I have had the same issue. I worked with a Samsung support member who was helpful in attempting to troubleshoot and log the issue. I ran my phone in safe mode for a few hours in hopes that it may have been an app I downloaded causing the freezing issue but unfortunately the phone froze again while in safe mode. According to Samsung, my next step is to go to a Samsung Experience shop in a Best Buy and have them do a software flash. I'm heading there today and if its successful I'll be sure to post about it.

samsung s7 edge freezing
i have a samsung galaxy edge 7 and it just froze on me too the screen froze and non of the buttons worked for the rest either so i popped the sim card n it unfroze.

Hey, this is software problem. Dont take it back phones. Maybe chrome, messenger freeze phone. Just send feedback Samsung. Samsung will fix this with update. Its not phone problem. Easy guys...

New Edge, 3 issues: 1. black screen, 2. camera prob, 3. odd sound playback behavior

Hi all,
Wondering if anyone else has seen anything like what I have seen with my new Edge.
I've had it for a week - I love the phone, the camera, the performance - there's a ton to love. This is the first phone I have not rooted and hacked on day one in at least 6 years.
OTOH, I have experienced 3 issues with the phone, after never experiencing a single issue in almost a year with an s6.
S7 Edge International, 64GB SanDisk Extreme Plus SD card.
1. Last night, my phone was in my pocket while I was doing some stuff, and when I pulled it out, it was completely unresponsive. Black screen, no cap buttons, nothing. I didn't even remember how to force a reboot - I haven't had an issue like this with a phone in a long time. I tried charging it (maybe the battery had dies?) - nope. I tried recovery-mode buttons, no good. I stumbled upon vol down and power, and it rebooted fine. No repeats as of yet, but is this anything anyone else has seen?
2. A couple of days ago, the camera wouldn't save pictures. I do not know why. It would open, focus, and the screen would do screen things, as if the photo was taken, but it wouldn't save it and it couldn't be consulted. Oddly, WhatsApp could still take pictures. A reboot fixed the issue, and I've yet to see this repeat, and I did try.
3. This one has repeated several times. I use Spotify for music and PocketCasts for podcasts. Sometimes, when I try to start the sound (with or without headphones), playback starts (the counter advances), but there is no sound. Changing apps doesn't change anything. I thought initially it might be that Game mode was locking out sound resources, so I turned it off - no difference. I tried killing any and all apps that might be stealing the sound - no difference. Once, after dancing around the interface for a bit, it started working, but other times, no. Rebooting obviously fixes the problem. This morning, on the way to work, I experienced the issue, so I placed a phone call - and after the call, the issue was gone. Has anyone else seen anything like this?

That's very strange, especially for the Exynos. I would try a factory reset, if that doesn't fix it, I would request an exchange.

Ugh, a factory reset does not sound like fun at all.

Yes i have had this issue 2wice so far - except that in my case the screen was on (once got stuck on weather page, and another time while i was in google play)
But as yourself - nothing worked anymore - no button no screen nothing at all - vol.down+power is the only trick that worsk
I am too puzzled as in what is causing this - i was looking to install some sort of even viewer app to see if there is a log - but couldnt find one
I cannot imagine what it can be - but whatever it is it completely freezes the phone - the screen wont go off - and it would literally stay like this forever....
2. A couple of days ago, the camera wouldn't save pictures. I do not know why. It would open, focus, and the screen would do screen things, as if the photo was taken, but it wouldn't save it and it couldn't be consulted. Oddly, WhatsApp could still take pictures. A reboot fixed the issue, and I've yet to see this repeat, and I did try.
I have also had this issue - but this is due to SD card not being read properly by the phone - this seems to be an issue with many users and again no idea what is causing it but i heard is due to poor SD tray design
3. This one has repeated several times. I use Spotify for music and PocketCasts for podcasts.

this problem i have not had but i never used the headsets so who know
Overall the phone works OK i dont want to return it just for this - but i do want to understand what can cause esp issue 1 and somehow happy to see its not just me having it - so maybe some sort of RAM/Core mismanagement > IDK
Also i have not had any single system updates since i purchased it on the 8th - so hoping one will hit soon and fix the issues :silly:

BTW fix for the Camera Failed issue is to turn OFF the Smart Stay option

I can add something simillar:
- sometimes the camera wouldn't open at all (error) and every time this is solved only by reboot; 2 times in 5 days already
- sometimes when scrolling in the settings menu, there appears some bluring frames (like an "indecision" between top-bottom...)

I encountered a similar problem with the camera.
While I was capturing a Slow-mo video the phone was getting really hot (Exynos international version, 32GB) but I was like, yea I knew that the phone would become hot because of the chipset so I continued.
At 4:58 the phone would freeze, non responsive to any buttons. After a few minutes the phone would reboot but the video got deleted.
I did this 3 times to check if it could be repeated and I succeeded. 3 times it would stop at 4:58 and crash and burn.
The fix for this problem is to switch from saving photos/videos to SD card to internal storage.
Kind of disappointed because the SD slot was one of the biggest pros to buy the phone..

guys - the camera failure issue can be fixed (until they release an update OTA next week) by disabling smart stay - not sure if this can also fix the slo-mo thing

Try turning off the App Power Saving mode!! This fixed my phone and now i dont have these weird freezes no more!!

Random issues on separate days (SM-935FD)

Hi all,
I have a black S7 Edge International version (Dual Sim version). The phone as a whole has been working great. I have been having certain issues though, they don't happen very often. So I'm not sure if its related to certain apps I have or if it's an issue with the phone.
Each issue happened on a separate day.
First problem: The phone froze when I was editing a photo on Adobe Lightroom. This was the first time I was using the app, so I launched after installing it. I tweaked a photo and noticed the phone lagging. They it froze, and I couldn't do anything on the screen. Nothing worked until I did a hard reset. Afterwards, the problem didn't occur again, although I haven't tried Lightroom since, so maybe I should, to see if the problem is with the app. Does this happen often with lightroom? Or could this be a phone issue?
Second Problem: On another day I had my phone randomly start vibrating, like it was receiving a call. I had just made three calls to my wife, and thought she was calling back. However, there was no call notification, and nothing on the drop down menu. There was also no ringtone. The phone kept vibrating, and wouldn't stop. I pressed the power button and reset, then the problem stopped.
Final problem: Today, I've been using the phone fine. However I was playing angry birds and then pressed the home button, so the game was still on it's memory, and being multitasked. I used the phone again a few times, then I noticed on the bottom that the game launcher circle (was on the bottom of my homescreen), even though the game was not open (still in the multitask window - I assumed) I tried to click the multitask window, and the button lit up, but nothing happened. The multitask window had frozen. Again it required a restart, and now it's working.
Given that I'm having these three issues (none have repeated themselves though), is this just the phone needing an OTA update, early phone bugs, specific 3rd party app issues, or is it a more serious problem?
Should I take the phone to Samsung and ask for a replacement, or should I wait it out?
Would love some advice from people, and would also like to hear if you've had similar problems.
Current firmware I'm on: G935FXXU1APB6
Thanks!

Does anyone have any feedback on this? Thanks!

I have the first problem on my phone.
But I didn't use adobe lightroom
and I've seen many user reported this problem in many different threads. it seen a known issue.

Thanks for that stone... Hopefully it's a bug... Would love to hear if anyone thinks that it requires a replacement... Also, i just found a dead pixel on the top corner of my phone... it's completely black...
Is that grounds for replacing the phone, or is samsung wishy washy about the whole thing?

I have the second problem; sudden vibrations with no reason, no app pending or anything else; I start to think it is associated with the Smart Alarm being activated (in Advanced settings).....
Anyway, really a bug, in fact the Smart Alarm and Smart Stay are known for having made other problems previously, but seems they didn't correct all the bugs.....

If there's a dead pixel I would return it.... There has been alot of people talking about freezing and rebooting... I've experienced too.... Most likely a software issue.... When I got the S6 last year my phone would reboot 3-5 times a day until a software update came out.... The continuous vibration I haven't heard anyone talk about... But if your still in you grace period I would get another phone for the pixels alone... Too nice and new to have to deal with that
Galaxy S7 edge

Hey, I have the same phone with the same firmware. I experienced the freezing right after I opened the camera from the lock-screen, it lasted for a few minutes and then went away. I'm waiting till Sunday to get the OTA and if I don't, I'm just going to update using Odin, considering how the firmware for the SM-G935FD and SM-G935F is the same.

Sounds good, thanks for the advice guys... I went to Samsung, and they said they would replace the phone for the dead pixel... Will take a week to arrive, but I'm just glad it's getting replaced...

I would return it immediately while it is within your return period.

i mostly had camera freezes from lock screen and random reboots.... hopefully a software update will fix it
