Random reboots - G2 Q&A, Help & Troubleshooting

Ok, so these random reboots are really starting to tick me off. Am I the only one getting them? I get at least 1 a day. Lately more like 2 or 3 a day. No matter what kit kat Rom I'm on.

Maybe they think you've got a silly username. :highfive: No random reboots here, even on aosp Roms. But I'm really pedantic about flashing clean and whenever I get funny software issues I kdz flash to stock. That always does the trick for me.
Edit:
Since random reboots are caused by kernel panic, have you tried changing kernels?

I always flash clean as well. I never had any reboots on 4.2.2 roms. I like kit kat, but these reboots are killing me..

So, I ended up getting a replacement phone due to another problem. I have put same recovery and Rom on, and so far no reboots since Sunday. Woohoo

FYI ~ Galaxy s4 (unrooted) self rebooting in stock rom

Service Provider - Sprint
Model no. SPH-L720
Just picked up my Galaxy S4 from Bestbuy with stock 'Build no.' (MDC). As soon as i started using my phone, sprint pushed a 'over the air' (OTA) update. Had it downloaded, installed, and rebooted.
As I started using the phone more by clicking on the stock app. the phone starts to reboot itself. Long story short. I thought i'll fix it by rooting the phone. Same issue and reboot itself more, kept crashing.
I now unrooted the phone using Odin-OC for FULL ERASE since i have nothing on the phone to begin with. I'm guessing this is a hardware issue. I'm wondering if anyone out there that is having the same issue.
Thanks.
If the Galaxy s4 is faulty (hardware issue), the phone vibrate twice before samsung logo appear.
so from what you are saying as soon as you booted you got the MDL update correct? what "stock app" are you clicking on that is causing the phone to reboot? random reboots are commonly linked to specific software malfunctions most of which can be corrected easily. not saying you didnt get the bad one from the batch but if you provide more info we should be able to work out the kinks if its software related.

Sorry for the late respond, my phone will automatically reboot itself. While in any apps, game app and while using the camera to take pictures; my phone reboot itself. Once it is on, the phone will not respond (freezes) and reboot itself again and again. This usually stop by the forth or fifth time of continues self booting.

i know you said that you are no longer rooted but have you tried rerooting and flashing a differant rom?
Typically random reboots are kernel related. When rooted did you try flashing any custom kernels, mods, try OC/UV, or anything along those lines?
Otherwise, sounds like a faulty device, maybe bad memory.
Same problem
A week after getting the galaxy s4 my phone started rebooting typically 2 times a day sometimes none at all, contacted sprint they said to come in and there fix was a factory reset lol, so decided to root and install triforce rom with kt kernel , still getting random reboots, im playing with the kt kernal settings hoping to find a sweet spot
Honestly... I think it's the MF9 update. It hasn't happened to me, but I've seen it for plenty of people. Everyone here running build no. MF9??
I am now, but my reboots started right when the phone came out

Very frequent random reboot from past few hours

I am facing so many frequent reboots from past few hours. I have not made any changes to rom or kernel. Till yesterday everything was fine.

it might be caused by an app, boot into safe mode and see if persist.
it could be battery issue, try with another.

Tracking down reboots

I've been getting reboots semi randomly for the last week or two and I was wondering if I could get some help on trying to figure out why.
Going back two weeks ago I was having some pretty poor battery life compared to some other users so I tried to do a full purge and restart. I went through the file manager on twrp and deleted any folder for any app that I wasn't using in a possibly misguided attempt to curb any file conflicts. After I did this I did a fresh install of cataclysm and Franco. After running into some reboots I tried with Kylo kernel and had the same issue. I then tried full wipe with Ubermallow and Kylo and had the same issue. Then I did a full lock, unlock, flash stock, root and recovery, and fresh install of chroma and Franco aaaaaand it still reboots.
I've had reboots randomly while listening to music but only 3-5 of them and in every install I've done I've had the same two apps do it. Starbucks app will reboot when using auto fill to log in, either through swiftkey or last pass, and Lyft will reboot the phone seemingly randomly.
What I want to know is whether or not this could be a hardware issue and if not how to get this to stop or if anyone else has had the same issue. It's seems so random yet specific and it's happened on so many different installs that I have no idea. I have been rooting my phones since the OG Droid so I have a pretty good idea of what I'm doing but I have never had an issue like this that lasts through so many installs of so many different things.

SM910F Note 4 5.1.1 Random Freezes and Restarts

Hello there xda.
I have a Samsung Galaxy Note 4 SM910F.
So what is happening to my phone is that whenever I am in any random app lets say reddit or even chrome for example. It will like freeze for a minute or two and then unfreeze.
In more extreme cases it will reboot.
So this happened randomly because I flashed a Stock unbloated 5.1.1 ROM from here back in december and everything was working smoothly and stuff. I had xposed installed and all my apps. Then in February it started with this random freeze/reboot. I had not installed anything else apart from what I had for the last 3 months.
So I restarted the phone, changed the battery and stuff to see whether that will fix it. However it didn't. So I formatted the phone (the soft type) just so I can install another ROM. So I tried another ROM, flashed the correct CP and BL and stuff and then just installed chrome and whatsapp. After an hour or two the same thing happened. So this time I factory reset he phone, like a complete wipe and I installed the unbloated ROM once again with few apps. Same thing happened...
So my last resort was to install Cyonagen Mod. After an hour or two same thing happened...
I don't know what is the problem. I read about some peoples phones emmc failing and thus the freezing, but I am not sure yet.
Please could you guys explain what I should do to fix this?
Thank in advance!
I have the same problem. Starting on mid january. I'm on stock 5.1.1 with root and twrp recovery
Tried backup and factory reset
I went back to stock after I factory reset the phone. And still had the same problems.
People say that its a hardware problem... So I guess I'll have to send it back to Samsung soon.
I think I tripped the knox. I just have to unroot and get it back once again to stock and send it back. I hope that they accept it.
i have the same problem. my model is SM-N910W8 and I bought it from 2nd hand, so no receipt and no prove of purchase.
can I still send it back to samsung to fix it?
same problem as you and now my phone died completely .
my phone was 4 months and he has not supported any longer he died naturally lol.
my operator gave me another free under warranty because the phone had a faulty motherboard and after several back galaxy note 4
This started happening to me a week or so ago and my phone just got stuck in a boot loop after it froze and rebooted. I'm on the latest stock firmware. Tried factory reset, reflashed stock firmware, nothing helps. It still reboots (sometimes it almost gets booted completely, other times it reboots after 2 seconds.
Just disable finger print. Yes that magic feature offered by Samsung is causing more hungry that happiness since S5

Many thanks. This was driving me mad for a few days, I had tried three different ROMS, completely wiping everything. I eventually went back to stock, which I'm still running and it was the same; it would run fine for a few hours and then start to lock up until eventually it would either reboot or stop responding and I'd have to pull the battery to restart it.
Just not selecting fingerprint security doesn't work, you have to force stop "Fingerprints" in Application Manager (All).
just do not setup the finger print lol. I was having those problemes too when I bought the note 4 until someone tell "do not setup the finger print" lol, not I'm a happy user.... I hope that android 6.0.1 solve the probleme

Still having the same issue around the same time everyone else started experiencing it.
I also was rooted and had xposed installed on 4.4.4 before the issue started happening.
Try the solution provided here & report back..

Random & Persistent Reboots

Hi all,
For the last 3/4 weeks my Moto X Style XT1572 has been randomly rebooting, usually this is when it is not in use and either in my pocket or desk.
I was running AICP and tried a couple of factory resets. This did not help.
I then factory reset and installed Dirty Unicorns (last weekly). Again this hasn't helped. No overclocking, undervolting, just stock kernels and I have tried handbag kernel.
Still rebooting.
Anything else I can try before throwing it in the bin?
Motorola are not interested in repairing due to unlocking the BL.
Thanks

Flash the newest stock 6.0.1.
Without botloader, gpt, no oem commands(don't lock BL).
You need stock system to recognize: hardware or software problem.
I was going to say that my wife's MXPE has been doing the same thing with multiple random reboots and losing constantly losing all her Bluetooth pairings. But her phone is completely unrooted and OEM Marshmallow OS.
I seem to have resolved the issue by using the Chill governor. Fingers crossed, but I've not had a reboot for 2 days now...

Mine is doing the exact same: random reboots and it loses all Bluetooth pairings and have to redo them. Running TruePure ROM but nothing else so far.
I did a Dalvik/Cache wipe and it calmed down a bit now, it randomly reboots about 1-2 times a week (over it doing it 1-2 times a day) and when it does reboot, so far, it hasn't lost the Bluetooth pairings yet.
Gonna see if I can go back to stock and install the latest updates and then take it from there, when I get a chance to.

Moto X Style , Android 6.0 , Not rooted, pure stock, exact same symptoms as you guys with the random reboots while not in use , losing Bluetooth pairings... Did a factory reset, didn't change a thing. Sometimes, I can get 2 days without reboots, then have 2 in the same hour the next day. It sucks. I'm hoping the Nougat update will fix this, if it ever gets released for my version...
Got 1 doing the same stuff, all stock, gets warm, reboot itselfs, wrong date and time, and no bt pairing
Mine is still doing it too. Not as bad as it was but at least once per day, when idle, sleeping it just reboots for no apparent reason. Not ROM, Kernel and I have factory reset.
