What causes random reboots?? - Epic 4G Q&A, Help & Troubleshooting

He so I installed Midnight 5.2 and for the first time in a long time I got a random reboot. I was just curious to know what might cause this to happen?

If there's a cause then it isn't really a random reboot now is it?

phone crash after missed call

having strange problem where after a missed call - sometimes - the phone just dies and I have to take the battery out to reset. Anyone else seen this - I have a few task managers that I think may be causing problems so have killed these already.
Thanks
JK
I'm having exactly the same problem!!! It's a super strage issue if you ask me!
I can play games for hours or browse the web and it never shuts off... But if I miss a call it's apparently shut itself off and only way to boot it up again is to remove the battery.
It can't be a heat issue since it doesn't happen during gaming and other stuff but only missed calls seem to trigger it.
Yes I've cleared the phone log a couple of times but that doesn't make any difference.
same here........not always but frequently this issue appears.....
Tried different roms, now runing cool kingdom sense 3.0 and for 2 days no problems and today it crashed twice...
could it be the radio rom??? anyone any solution yet or would it be a hardware failure...
Only fix now is take out the battery......

Evo reboots during use

Weird problem, had my Evo for a couple of days now and everything seemed fine for the first day but now when I run certain apps like google maps for pandora my Evo will reboot. This doesn't happen all the time but will eventually happen after an hour or two of usage. I did buy a case for my phone, maybe it's a heat issue?

I've had this happen on my hero. It is just clearing memory are you using autokiller ? It started on my hero when using autokiller. It's not a heat issue the led will flash red and green when the phone is hot.
I'm using advanced task killer but I don't think it's set to autokill apps. A hard reset has seemed to fix this issue for now, how do I ensure it doesn't happen again in the future?
It might help to check your preset in autokiller and set to moderate or optimum but some apps use more memory than others so you might see it from time to time. I still use autokiller set on extreme and would only see that once every week or two on the hero. So it's not that big of a deal. You could just uninstall it if it bugs you or to see if it stops. I have not seen it on my evo yet but I am just rooted no custom ROM yet (Waiting for fresh ROM with espresso theme). That might help contribute to it as well.
taziz23, I don't mean to hi-jack your thread but I've been chasing down the cause of random reboots also. I've been searching around for someone with a similar issue and all I've been finding are people talking about the reboot loop caused by an exchange account. I'm not using exchange at the moment so I know that's not what's affecting me.
It sounds similar to what you're talking about. About 30 minutes to an hour apart regardless of whether I'm using the phone or not. It just did it while sitting on the desk next to me with the screen off for at least 15 minutes.
I've hard reset a few times to see if it was related to the OTA, and turns out it happens to both .1 and .6
I've found out that if I don't associate my google account during the initial setup (or any other accounts like facebook, twitter, etc.) it doesn't seem to reboot anymore. Once I do setup an account and set it to auto sync, I start seeing the reboots happening. So I've been playing with different combinations of disabling calendar sync, contacts sync, etc. to narrow it down but so far, I've come up with nothing.
I've even exported my contacts to a .cvs file using my desktop browser and cleaning out any of the <HTCDATA> stuff that links facebook and twitter to make sure nothing is corrupt and reimported them, but as the reboots are still happening, it looks like that might rule out contact corruption.
I had made it through most of Friday before the reboots started. I recall installing the update to Facebook and TasKiller just before it started happening, but have hard reset since then and have not installed either of these again.
Has anyone else seen anything like this?
Two words: Kernel Panic.
Actually, that's just a guess. I'd imagine anything else would cause some kind of error message to show up like a force close for example.
It has happened with my Evo a few times so far. It also happened with my Hero when I use to use that.
It's probably just a module misbehaving which confuses the OS and causes the kernel panic, so I imagine it's nothing more than a software bug.
Yea... I was thinking some KP's might be happening, but if the release build is dated in April, I must have some fluky hardware right?
Maybe I'll run an `adb logcat` and just wait.
I remember the hard crashes on some of the early donut and eclair builds for the Vogue (CDMA Touch) and these are pretty much the same deal. Just drops out and goes straight to the bootsplash.
Regardless of the phone or OS, I've seen this happen on all the phones I've owned. Android is at least open to allow normal people to debug and fix these problems though.
Me too!
I had a seemingly random reboot happen today on my EVO as well... then it happened again.
Both times, I had Waze and Pandora running and was about 30 seconds into a phone call.
Advanced Task Killer is installed, and is set to kill "when screen off".
I'm pretty new to Android based phones, so I'm not even sure where to start with troubleshooting... but found this thread, and thought this info may help.

(P.S. I love this phone so much, right now - I don't even care that it has rebooted on me twice in the middle of a phone call... but eventually the honeymoon will be over, and I'll want this figured out. LOL)
I am having an exact same ISSUE i got it from google I/O its just happened suddenly while you are using it I have no Idea .. Search is also not that great .. Platform need lot of work until it get mature .... I was definately enjoying 1st 2 weeks but not anymore its just killing me now ... Issues after Issues so many Bugs I have start noticing now.. I am not complanning but its just not solid they need to fix this asap... I was enjoying Pre it was slow but I like that OS .. not too much buggy... some apps just Crash randomly .. I was huh .. and its doing more and more now ..
After my hard reset a couple of days ago I haven't had any reboots. I do think it was related to the task killer I think it might have caused some data corruption possibly when killing an application. I set the auto killer to safe in the meantime. If it stats happening again I'll try uninstalling the task killer before I hard reset.
I had the same thing happen, but only once. I was using google maps I think. I also have advance task killer installed. Does the ignore list in advance task killer and setting it to auto kill, kill everything except for what's in the ignore list?
I'm not sure but I did notice that most of my reboots were happening when running google maps..
My Evo rebooted most days 4 or 5 times, day or night, in use or not. The store where I purchased it refused to replace it since I couldn't duplicate the problem to the local technical store. They acted like I needed someone to talk to and not like I had a problem needing resolution. After about 20 calls to customer support they told me to return it where I purchased it and they're sending me out a new one. Apparently no one at Sprint has ever heard that there's this issue. Mine was stock. Period.
I have had some reboot issues that I can't explain. I removed Advance Task killer and it seems to happen less frequent. Maybe once every two days, but never during a call. Waiting to see if this stops with Froyo.
Used to have similar, but less frequent, reboot issues and an occasional "frozen" screen with my previous Blackberry 8830.
I've only had it reboot once or maybe twice for no reason but When I use advanced task kill I almost expect it to happen. And I only use it to kill whatever app I was just using and any other ones Ive downloaded that have no business running.
I have had the same issue, only I am using the full version of Memory Booster..I am going to uninstall it and see if that helps, I also notice that my phone was very hot. It rebooted about 3 times before letting me use the phone again.
Any other suggestions?

Bewildering, consistent, recurring problem on CM6 and CM7

I first started using CM at 6.1.2. I'm now on CM7 RC2 and the same problem still occurs. I have no idea why this happens but I'll provide as much info as possible in the hope that someone will be able to figure it out.
My phone will work completely normally for several days after I initially flash CM6.1.2 or CM7. After a few days, a crash will occur where the screen stays on but the phone is completely unresponsive to all input -- touch, softkeys, or hardware keys. The power button stops functioning. After a while, the screen dims and the phone reboots. After the reboot the phone chugs along for a few hours and then the same thing happens. This crash almost always occurs in the Browser, in the middle of loading a page. I don't think it's a memory issue because I consistently have ~100MB free for RAM.
Also, I don't know if this is at all related, but I often notice just before the crash, the haptic feedback from the phone for keyboard presses and the softkeys becomes very erratic and inconsistent.
I can never get a logcat because the phone restarts after the crash. Has anyone else seen this or know what might be the problem? Again, this has been happening all the way since CM6.1.2 (and possibly earlier, I haven't tried anything earlier than 6.1.2 though). This is driving me pretty crazy, and I really love CM and would like to continue using it, but this is kind of a dealbreaker.
Did you wipe between flashing CM6 and CM7?
Yes, I always wipe data/cache/dalvik between flashing.

Random Reboots

Does anyone else suffer from random reboots with there device? it does it twice a day or more for me???
Is there anything i can do to stop this issue from happening again?
I.e wipe user data???
I've had it once or twice. Presumably a rogue app or a bug in the system.
I haven't suffered from a random reboot at all since having the phone on the second day of availability in the UK.
Then again, I haven't rooted mine, unlike others...
Yes I have had a few reboots in the few couple of days. Been ok since though

Not a single crash or random reboot so far. I rebooted last Friday after charging my battery and it's been running since without problems. My best guess is that culprit is one of your applications that you've installed, especially any application that tries to do something with Android and the device itself.

I had these reboots on a G2X and it drove me bonkers so I am always worried about phones doing it and I watch uptime like a hawk. Nexus has been rock solid since I turned it on the first time. No reboots. Sometimes it's apps and sometimes your use case just exposes a bug in the OS. Try doing a wipe and installing a few apps at a time so you can figure out what's causing it n
I had a couple within the first few days... nothing for a while...
This is just speculation, but I remembered seeing a thread somewhere in another form, in which a user with another device with the same random reboot problem was advised to check his sim card. A bad sim card may "vanish" for a while, causing the device to reboot. Again, just speculation, or if you wish, a hypothesis you can check.
I have something similar, the first time was when I was charging my phone, I woke up in the morning and I found my phone off and hot as hell. Battery pull and everything went perfect. then it happened to me 5 times, the phone freezes and turns itself off, then I have to do a battery pull! the last time was today I was listening to some music, then the music went weird, then the phone froze and turned itself off.
I called Three for a new phone as I have it for under 14days
It looks like there is an issue that google hopefully acknowledges like they did with nexus s.
I was listening to music on my way down the sidewalk thus morning and the mp3 started doing a loop of about 1 sec of the track over and over. Finally heard a pop and it went silent. Had to do a battery pull when I got on the subway.
Then on the subway about 10-20 seconds into a track after starting some music back up the track restarted. So I stopped playback thinking it may happen again.
I'll try to do what I can over the coming days to recreate this.

I would think that would cause more problems than that. I was listening to some tunes for a bit last night with no issue. And the issue this morning happened with two different tracks.
I had added a battery gauge widget to my home screen last night, I removed it just now. I'll try to recreate the problem from here without adding more apps or widgets. If I can successfully recreate it I'll try to hook up adb and get some logs.

I'm having random reboots too. I'm suspecting its something to do with either GO SMS or SlideIT. Do you guys have any of these installed too?

None of them and no reboot so far.

I'm getting another problem now. I've taken off GO SMS so I dont think its that. But when I get a notification (i.e SMS, email), I go to wake up my phone and the unlock screen appears. However it wont recognise any touches on the screen, then sometimes it will come back to life and other times it will reboot itself.
Never had a random reboot, I have go SMS installed.

Just had a random reboot with none of the aforementioned apps installed.
I was having random reboots when the phone was just sitting there with the screen off.
I had SetCPU under clocking when the screen was off, I removed SetCPU and my random reboots went away.

Random reboots

Hiya folks,
Just wondering if anybody has been experiencing random reboots on the OP3. Have been experiencing em on 3.2.1 and 3.2.2 about twice a day since I got the phone four days ago. Tried a cache wipe/hard reset but to no avail. Haven't been able to reproduce the reboots. Just happen at completely random times, while writing an email, making a call, or connecting to the car Bluetooth. Phone is perfectly responsive and stable otherwise!
Have asked Amazon for a replacement, but I'm wondering if this is something that's been noticed by anybody else. No mods done, completely stock. Running dual sims (Vodafone and Jio VoLTE).
Attaching a screenshot of how the battery page shows the reboots.
Yeah, they happen for me periodically. Not nearly as often as yours though. Mine is maybe once or twice a week max. But yes, slightly annoying.
Phone is completely stock, locked, unrooted. Running 3.2.2.

Haven't had a single random reboot yet, had the phone for about a month now. Started with 3.1.3, then 3.2.1, now 3.2.2, rooted, running xposed (not a lot of modules).
What are you doing when the reboots happen (an app issue)?

It's been all over the place, but often when the screen was actually off! The way I would know would be I'd pick up the phone and see that it asks for the PIN post reboot. If it helps, I've enabled encryption. I also have a work (exchange) email account set up as a device admin
I know there's ways of investigating this with logcats and last_kmsg, but I've had the phone 4 days and I cant imagine why it's spontaneously rebooting while doing literally nothing. Seeing as hardly anybody has had similar reboots (on XDA/OnePlus forums), could this be a hardware issue at all? I could possibly try reflashing the entire phone, but that would essentially be the same as a wiping data/cache, right?
Here's an idea - my LTE data/VoLTE is extremely spotty (on Reliance Jio which is in a beta test stage) - disconnects and connects VERY frequently, could that be triggering reboots at the baseband level? Now throwing ideas at the wall!

Mine had random reboot issues recently on a trip. It only seemed to happen when I was using Google navigation combined with listening to music on my bluetooth headphones. I haven't tried that combination since the trip and haven't had any reboots since then.

same issue
the reboots are random, and i could only know that the phone has rebooted itself if it ask for a pin upon scanning finger, went to service center and has OS flashed, but the problem still persist, for me some time when the phone hangs, some kind of pixels form on the screen, attaching a sample photo for reference, anybody experiencing this issue or am i the only one, and today the phone has completely stopped working, it is not switching on.

Wow that is substantially worrying, and almost certainly not just a software issue I reckon. Try getting a replacement maybe? - or atleast ask the service folks for a mainboard replacement. Anybody else with reboot issues?
Doesn't really seem to be an OS bug, unless it happens in very niche use cases which I don't have anyway! Getting the replacement on Tuesday, fingers crossed for that one!
My friend and I both got a one plus 3. He does not have this problem but I have.
The reboot is random but usually happens during charging. Sometimes it even turns off.
I have tried to ask for a replacement but they rejected me. Still communicating with the support staffs

Went to service center in Gurgaon, getting a replacement for motherboard, as oneplus policy doesn't give replacement handset, have to SETTLE for this, i dont know how many days this whole process is going to take, will update you guys about it when i get the phone back.
I have the same issue, random reboots usually when screen is off.
3.2.1, root + xposed... for me it started with 3.2.0 update

I experienced a similar scenario twice, only seems to happen on long trips, 3+ hours. I was using Waze with Plex streaming audio over car Bluetooth. I have not had this on shorter trips, 1-2 hours. I'm typically plugged into the dash car charger. Otherwise, haven't had issues. Never rooted 3.2.2.
Situation Update
Got the replacement OP3 on August 9. Have now seen 2 random reboots since. Once while paired to the car Bluetooth, once after finishing a call.
I have till August 19 to decide whether to keep this device or ask for replacement number two! Overall, the reboot situation is a lot better on this device, but I can't help wonder - why any at all?
Seems at this point to either be a bug with the Bluetooth implementation AND/OR with the dual SIM functionality where repeated switching between SIMs for every call. (I use one SIM for calls and texts, another for data)
Can anyone confirm the situation on a custom ROM as opposed to stock? I'm running stock 3.2.2
Aaaaand now we have an ota claiming to fix 'auto-reboot issues' - 3.2.4 :laugh:
The reboots were so sparsely documented compared to the other stuff that I ended up getting a replacement for a s/w issue!
Anyway - you folks reboot free now? Post results with 3.2.4 please
I had three back to back random reboots while using Google Maps and Amazon Kindle in the background. Weird.
I've yet to have a random reboot on 3.2.4

Had several reboots while driving and navigating on google maps one after the other. Maybe it is to do with the GPS sensor but its annoying coz you need it most when u r navigating turn by turn

Agree. It happens only when I drive with gmaps running on background. When the screen times out, the phone, instead of shutting down the display, goes to hard reboot.
I've never had this issue until I moved to the latest update. Weird. Annoying.
I had my first reboot a few hours ago (with 3.2.4). I was connected to Bluetooth in my Car. Noticed it, as my car told me that mein Phone is now connected. No gmaps or something with GPS runinng.
Looks like Bluetooth is the Problem.
