Random Reboot? - Samsung Galaxy S8+ Questions & Answers

I was walking around with my GS8+ in my pocket listening to a podcast when the audio suddenly stopped on my Bluetooth earbuds. I pulled out my phone and saw the Samsung logo. About ten seconds later I got back to a lock screen, and it told me that the phone had rebooted.
Is there anything I can look at to see WTF happened? This has never happened to me before.

Hi,
i also have this issue, I already wiped my phone. i think this is a hardware problem

Every Android as this problem the only question is how often. I got S8+ the 1st week when it came out in Czech and in all the time since now, it rebooted for no apparent reason like 3 times.... IMHO it depends on how often do you restart your phone. If I leave it like month or 2 it is more probably this will happen. Best to restart like every month or so....

Pattern to my reboots - do yours have a pattern?

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.

What bloat did you remove? I've removed most but not all of it. Can you list it?

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.

Is it completely bricked? What should I do?

So I bought this Huawei Mate 8 and to be honest I really loved it, it's the best phone atm imo. And it's pretty expensive in my currency. I've owned the phone for a couple of months now, 4 months I'd say. And just 12 hours ago, problems started.
It all started when I attempted to use the fingerprint scanner and my phone randomly restarted. Huh, I ignored it. But it happened again when I tried to open settings. It'd crash randomly on random actions. But it almost always crashed when I tried to open settings or use scanner. I removed my SD card and then it worked fine for a couple of hours, then it restarted again.
And sometimes it restarted many times over to the point where I'd think it's boot looping. But it'd eventually start. I reset the phone hoping it'd fix the problem if it's software related. But it always restarted right before I could enter my Google account to start the phone. But it reached it's eventual death. It crashed again but it didn't restart this time. I tried connecting it to its charger, but no response and no heat at all, not even in the charger's adapter. And my laptop didn't detect it at all.
What should I do now? This phone is new and expensive. I'm very careful with my devices and it's in a perfect condition. The only incident with it was when my selfie stick got too tight on the power button for like 10 seconds then I took it out. That was the same day the issue happened, so I'm not sure if it's just a coincidence. Anyways please tell me what I should do right now, and yes, the phone is still in warranty but I doubt they'd change it for me, their customer service is **** where I live.
Update
A couple of hours later, it was completely and utterly dead. I tried to press the power button and it turned on, it froze on the Huawei logo for like 3 minutes then it restarted again. It's acting really random right now, random restarts and then completely dead, then alive again...
Update #2:
I hard reset again and it's working pretty fine for now, I'll update again soon, but I strongly doubt that the problem is gone.

my phone turns itself on at night constantly!

Phone is an AT&T Samsung Galaxy S1 (technically a Captivate something or other, 897 or somesuch?) which has one of those PacROM sets for android 4.4 on it. (I will post exact specifics if needed in followup but the battery is dead AGAIN thanks to this)
For several months now the phone has started turning itself on at varying times. Sometimes its the same time every night, then maybe it will change to a different time later. I've seen it happen (having been sitting awake late at night to see it bling on in the charger surprising me) and can't figure out how - nothing is changed vs when it wasn't doing this before. I know it's doing it all the time now because my battery keeps ending up DEAD when I shut the phone off fully charged for when I later need it, only to find all the sudden it's on zero yet again.
There are no set alarms of any kind waking it up, i'm not aware of any PacROM feature and didn't set or change ANYTHING. The phone worked fine the first 9 months before starting to act wierd. I've installed next to nothing on the phone since then either.
When the phone powers up it doesn't do anything at all - just sits at the main menu and drains battery until it has no battery left. It doesn't act like it's loading anything, or doing virus stuff or that. If I catch it in the middle of a powerup and take the battery out, it wont retry that night though.
How do I narrow down what is happening or causing this to occur??

New Bluetooth device causing random restarts?

A couple days ago, my (OEM firmware) 3a started randomly restarting even when it was just idle in my pocket. The only thing that I had recently changed on it was to connect some new JBL Endurance Peak II true-wireless earbuds, which I used for a couple of activities. However, even doing a "Forget" on them didn't fix the reboots, so I ended up doing a factory reset and installing a subset of my previous apps to see if I could find the culprit. It ran OK for over 24 hours, so this morning I connected the earbuds again and used them for about an hour with no problems, then put them away. A couple hours later, my phone has just done a spontaneous restart again!
Does it make sense that connecting a BT device could do something like this? The buds are a new product where left & right can operate together or alone, so maybe something different there. Any ideas??
My next thought is to do another reset and this time wait for several days before reconnecting them, or maybe at that point I'll assume they're the cause and return them while I'm within the 14-day return window. Or maybe a newer phone (Pixel 5) might take care of it?

Question [HELP] 5S rebooting at random all night and Asus won't honor the warranty

Yesterday, 10 minutes before a major interview, my rog phone 5S locked up while reading a PDF. It froze for 5 min before rebooting itself. It responded to no input from me at all, not even attempts to get to the bootloader. When it started back up, nothing worked without crashing. I powered it off and switched to my old Pixel 4 XL to do the interview, which worked out fine. I then went back to my 5S and tried to get it working. At first it was fine and I could make and receive calls, but I could only receive texts. I couldn't send them. I left it be for a while longer and then it started rebooting on its own at random. At some point in this, texting started working again and it was fine for a few hours till I went to sleep. However, during the night it started rebooting at random, constantly waking me up. I turned it off, but that didn't stop it. It would turn itself on and reboot. I got next to no sleep till I buried it in my dresser and clothes. I did a reset last night, before going to bed, and I thought that had fixed it, but clearly it didn't do anything except cause me a **** load of unnecessary work.
I went to file for an RMA just now. I provided the serial and ASUS said they won't honor it because it's an international model and has to be returned to the country it was bought in. I have no idea where it's from. I assume China and I can't read Chinese to do any of that, much less know where I'd even go to start that process. It's an expensive phone and I'm without a job right now. I don't know what to do.
I've had nothing but problems with this damned phone since day 1 and I'm sick of it. It's awful. The ROG Phone 3, which I also have, is only slightly less problematic. At least it never did this. I only have it for the gaming controller at this point and I'm gonna get a new phone once a phone comes out with the new Immortalis GPU.
Any help would be greatly appreciated. I want to pot on the ROG Phone 5 subreddit, but they are restricted and IDK how long it'll take to get approved. The last restricted subreddit I applied to took 5 months.
