Anyone else getting random reboots on their Nexus 9? I I have had 3 already this morning, always seems to be when I'm in a Google app - Play, Music etc?
Any ideas how I can diagnose this and stop it happening?
None in my 24hrs of ownership.

If I had random reboots I'd flash the factory image and see if that solves it. If it doesn't them rma the device

Well I had it running all morning connected to logcat, and I didn't get one reboot.
If I get another one, I might flash the stock image!
Since I adb restored some of my apps from another tablet I have had nothing but reboots. It's getting very, very annoying.
Is there any logcat or last.kmesg I can get that would tell my why it's rebooting??
UPDATE : Just checked and there is no last_kmsg in /proc, anyone know where it is now?
I had 1 sudden reboot in the 3 days of ownership.
This was after an antutu benchmark (which crashed), then I opened a process viewer app which rebooted the tablet (but otherwise just runs without problems).
almost once a day
i am experiencing random reboots almost once a day. I am wondering if anyone made any progress with these?

Have you flashed the factory image to see if that cures it?

I had a single reboot since I bought me Nexus 9 soon after it was released and I use it multiple times a day.
I would highly recommend clearing cache and data for the apps you suspect are causing the random reboots.
If that doesn't work, try resetting your whole tablet.
I never had a single reboot since I bought the device.
Maybe it's because of the restore option at the first start of the tablet? I never restore apps and data and there are no problems.

Factory reset? No. Was it mentioned it fixes issues?
Yes
Me too
I've been getting these too, not quite as frequently though. It also doesn't seem to matter what app I'm using. It really is random. I usually see it happen a couple of times a week. I'm not a heavy user. I've been reluctant to reset and I've been holding off on unlocking, rooting, etc at least until it's out of warranty. I guess it's time to try a reset though.
Has anyone who was having the random reboot issue tried resetting back to factory and confirmed that it resolves the issue? I saw people recommending it but I didn't see anyone state for sure that it had solved the problem for them.
My tablet reboots roughly once per week. I've reset the tablet several times and flashed it twice. I didn't download any apps to eliminate any potential conflicts. All to no avail.
The device info on my profile needs to be updated.
For some strange reason I installed One Drive and my tablet went mad, massive slowdowns, reboots many times a day. Removed it and it's been rock solid since...
my wife's Nexus 9 has random reboots at least once a day, as well. This happened when it was stock and as a test I just put a ROM on it and it still reboots. I'm thinking about calling HTC to see if we can get a replacement.
Did you get an progress on this? Mine is doing it, totally stock not rooted. I'm about to reset and start again. Just want to make sure it's not hardware as I want to look at custom roms and rooting fun
Hello,
i had bought a Redmi Note 4 and had received today, but when i try to use i had looked a problem because cellphone is randomly shutdown, after shutdown i need to wait about a 2 minutes to try to start again. After 6 minutes phone shutdown again, and i have same problem to start.
I can't believe that is overheating because its a new cellphone and as i said i had received today. I had tried a reset and no success, phone still shutdown.
Thanks
Overheating
I had looked that is a overheating problem, when system comes to 60 celsius cellphone shutdown.

Yes, i had installed other rom and problem persist. But have one thing, when i look for fastboot mode screen cellphone stay on screen up to 10 hours without poweroff, but its only start system that cellphone shutdown because overheat. If cellphone are "hot" it does not start, i need to wait to cellphone goes to cool to start and wait up temperature goes to 60celsius and shutdown again.

Hmm very strange, would start to think hardware problem if it persists between Roms. But you say it's fine other than after its booted into the ROM itself. Have you unlocked the bootloader, what Roms did you try?

Hi i had tried a 8.1.2 Miui, 8.0.4, global and chinese.
MY bootloader its locked, i'm waiting for xiaomi allow my unlock. When i boot on fastboot mode cellphone does not shutdown, but fastboot mode its only screen of fastboot, its not a system. I believe that cellphone is not heating, but its not sure.
Thank You
I'm believing that is a software bug, because when i plug he shows error message "Please plug out", and few minutes before i had started system and shows -3 Celsius and heat up to 60 celsius and poweroff again.
I had drain battery in fastboot mode and trying to solve this bug.
Maybe you could try flashing to the latest Global developer 7.2.9 & see how it boots then.
Other than that as gsmyth eluded too it's most likely hardware & I would be in contact with your seller A.S.A.P for a replacement.

Solution for redmi note 4 random shut down
I have faced the same problem for few days later i open battery saver scheduler for starting and shuting down phone timings its 12 pm to 6 am so i just off it both solved
Guys, do you still face it? I have new Redmi Note 4 with latest stable MIUI 9 and Android 7 and my phone just rebooted from no reason during a phone call...
I just had the same issue that started 2 days ago. I was running the latest official Lineage 0S and the device started rebooting every 2 minutes or so.
I tried wiping cache and dalvik which didn't help. Then I clean flashed the latest Pixel Experience and after about a day of using it the rebooting continued.
So this morning I flashed the stock fastboot ROM to see how that goes... and so far so good. I really hope it's not a hardware issue.
I will post here again if my rebooting starts again.

So? Did it stop? Mine is rebooting randomly. Tried every ROMs but dunno it didn't cause any issue in those although in a global stock ROM it happens frequently. Worth mentioning=> I had to root my phone. Wiped all my data, installed the old default stable ROM etc. still the issue persists. Did an analysis from Simple System Monitor app I gathered that everything is running okay except "pa_therm0" is showing whooping 95°C temp! Dunno it could be a wrong reading but anyone could help on this then I'd appreciate

Do you have a second SIM card inserted?
I figured out a while later that having a sim in slot 2 causes reboots. With an SD inserted and no SIM, reboots have stopped pretty much entirely. A friend of mine with the same device has the same issue even though he's running stock. I'm not sure if it's a factory fault of all devices but I'm afriaid I just need to use my phone as a single SIM device from now on

Yes I do have double sim cards inserted since 8 months. It could be a problem for my random reboot issue. But, recently I've cleared both Dalvik & cache partitions through the Recovery mode. People in other forums have mentioned that this solution has worked for them. Gladly till now there hasn't been any single random reboot happened by so far. Rest assure I'll keep you updated

Glad to hear it Wipe Dalvik & Cache is always the golden rule when dealing with custom ROMs.
Sadly though, it made no difference for me. Only thing that helped me is removing SIM 2

Well it seems like for me wiping Dalvik Cache & running on only 1 sim methods didn't helped at all. So I stopped using processor & battery hungry Snapchat app. Guess this should help.
You guys when you face such problems after you brought a phone you should definitely go and have it fixed or replaced it(or get your money back).Do not rush and unlock bootloader thinking that it will help you because if it is hardware problem it is over, and the service center has every right to blame you for its damage since you messed with it.Like my lg g4........

I only ran into the problem after unlocking the bootloader because I had only used one sim while everything was still stock. I know I could relock bootloader and send it in and probably get a knew device, but to me it isn't worth it. The cell service providers in my country are notorious for taking their time with repairs and replacements. It's not worth the 3-5 months it will probably take... I'll be just fine with a single sim.
I've had my honor 10 for over a year now,never experienced any issues,not even after updating to emui 10,however recently ive noticed the device restarting itself while not even in use,and these days its starting to sometimes freeze and reboot. Has anyone experienced anything like this, i am considering to do a factory reset however first id like to hear if anyone has any other ideas what could be the cause.
I'm experiencing exactly the same. I had no problem in two years but for the past two days I think my honor 10 froze and rebooted maybe 5/6 times... It's completely random, three times when I had the phone in hand, the other during night or non using period.
I'm also on emui 10 since it was available : currently on 10.0.0.177(C432E3R1P4patch01). @Anubiz_DK did you find any clues ?

My problem was the same, factory reseting it worked.
Started having same problem myself two days ago. I really don't want to do the factory reset, but it seems like it is the only way ?
Update, after the factory reset everything was good for a month, yesterday the issue came back, no apparent reason why
I had a similar problem, but after a couple of days it went away by itself.
Im also seeing visual bugs before some of the reboots, like colorful squares and such
I wiped cache partition yesterday and so far so good. Before wipe it was restarting 5-10 times a day.
Did the same today and it seems to help
Also i how much free ram do you have without an open app, seems to be conected to the issue, both time i had reboots it was around 800mb and 1.12gb,after wiping the catches ive stayed around 1.8-2.0 gbs
About 2 days after wipe of cache partition the reboots started again. No apparent reason why. Sometimes it happens when in use, sometimes it happens when not it use. Some times there are plenty of apps in background, sometimes 1 or 2. Sometimes it reboots 3 times in a few minutes, sometimes it goes 1-2 days without reboot. Heavy use and multitasking doesn't seem to trigger the reboot. Few times it even rebooted while booting and once it booted to safe mode.
Anyone tried checking if it could be a hardware issue, and are you all on emui 10
Im on EMUI 10. I can't think of any HW issue. Maybe RAM related?
The reboots started to intensify for last 4 days. I get about 5-15 daily at various situations. Formatting cache partition doesn't help anymore, i got one reboot about 5 minutes after wiping cache partition.
I just got August security update along with system update 10.0.0.180 (C432E5R1P4). Will report later if it helped with the reboots.
Well I got one reboot yesterday and one today. So no help here..
I have a new theory after traveling last night on a train, for a while there were no reboots, but as i was in a hell hot train last night the phone could not stop rebooting, sooo im imaginine its possible overheating issue

Hi! It's unlikely, IMHO, since my phone reboots too, but it's of ~room temperature, no signs of overheating. Maybe, it's thermal compound bug/lack, but unlikely.
At 4PDA, I've counted around 10 people having the same reboot issue. I've asked some of them here, but we don't know the reason for sure. 4pda.ru/forum/index.php?showtopic=904618&view=findpost&p=101416402
So, still guessing. One of them said that After downgrading to android 9.1 and resetting , her phone runs just fine. That trick does not work for me...
Important note : for the cases I've seen, it has started ~within 2 months (around Sept 2020)

I can confirm that. And I think it is quite strange. Could it be something with NPU unit?
BTW, I have early unit. I bought it right when the phone was available. In 5/18.
It had stoped. and it started again, honestly i have no idea at this point, there is no good reason for all this, im done with this at this point
I'm angry. I have sent my phone to RMA, the last day of warranty, 31st May 2020. The USB-C connector wasn't able to transfer data and it couldn't fast charge.
They actually accepted it and changed everything except motherboard. So 3 weeks later in June I got basically new phone back, with new battery, display, back cover... And because I wiped it before sending it to RMA, I did clean install and rightaway also a clean install of Android 10. Everything was working perfectly, battery life was great..
And then the damn reboots started, late September or early October. It pisses me of, since the phone has been recently refurbished in official service centre within the warranty. I was expecting to be able to use it quite comfortably for at least another year since the service. Possible up to 2 years...
The Zenfone 9 is a great little device. However, since today I have seen several automatic reboots of the device. Anyone else seeing this problem?
I haven't seen a reboot; any new app you've installed of late?
Good hint - I have installed one yesterday. Will uninstall and report back.
Unfortunately is still get 1-2 reboots a day. Not critical but annoying! Anyone else?
I'm on latest update and unlocked+rooted. Not a single unwanted reboot.

Yes I am. No worries. Device is great. Just software.
Did a hard reset - problem persists. Not sure what the cause is - working with Asus support on it.
Hi, a friend of mine with a ZF9 has got reboot every night during charge (he uses slow charge, this night he'll try normal charge).
He had reboot even during daytime, he did a hard reset yesterday and for now everything is ok, but I'll update with new info in case of.
I've been having those reboots for weeks now. There is an official thread on the asus forums talking about it. There are more than a dozen people who have also reported it and from the looks of it, Asus hasn't found the source of the problem yet. Out of curiosity, in which country did you buy it? Are you rooted?
my version is a french version. I neither had any beta OS on it nor was it rooted. I wanted to provide Asus with Logs but they rather wanted the device for repair, now I'm waiting for its return.
I doubt this is a hardware issue though as the reboots did happen in cold state w/o any system activities ongoing. The only special thing on my setup was that I used two sim cards in parallel.
I did a hard reset and he problem remained. I also used slow charging.
I'm from Italy and the phone of my friend is not rooted and with bootlloader locked.
I heard my friend minutes ago, and from when he deactivated programmed charging the issue seems to have disappeared. Have you got programmed charging on?
Yes, I have the upload scheduled. But I'm beginning to suspect that the problem originates from a lot in Italy. I just asked you because I thought it was from there.
Love this phone but also having the same issue. Bought from Asus directly (US site) too. There's a whole thread of folks with the problem too on their forum:
ZenFone 9 randomly restarts

Try to deactivate it and report please ;-)
My friend hasn't got reboot since then for now, two days and a half ago.
My reboots do not happen while charging, FWIW. And they're always while the phone is idle (sitting on desk). I look up and see it's spontaneously rebooting...
I was having reboots on custom kernel, just updated to 32.2050.2050.34 without going custom kernel (still rooted) and have had no reboots yet.
Mine reboots while watching YouTube app, either with high brightness, while charging, or both. It seems to be less likely to happen if i clear cache from YouTube settings.
It typically doesn't happen in other apps. Phone is stock. EU version.
After testing for a few weeks, there is a good chance that the reboots on my device are due to Magisk (not modules)
Hello. I've heard that the Chinese (OnePlus Ace 2) version of 11R has some issues after flashing from Color OS to Oxygen, like not working fingerprint, not working OTA update (if you update, you get a bootloop), issues with notifications, etc. I have ordered one from china and I am a bit worried. Can anyone confirm this?
Mine is from china and it is oxygen now. I only experience issue that sometimes when I turn on the screen it will flash rapidly for a couple seconds.

I ordered one from china too.They also changed from color os to oxygen os.Now I'm facing the same issue as you.The issue doesn't happen every time tho like when I open the phone and it will start to flicker for a sec and then the screen goes dark for a sec and returns to a normal state.I'm just concerned that the issue will damage to OLED somehow.I'm also experiencing regional sim problem.Eveytime I reboot my phone, the warning note shows up (you're using region-cutomized phone......) and it kinda annoying even tho I can make phone calls and use internet as yet.
I got mine yesterday, but many issues occur, flashing screen, autobrightness does not work at all, alwasy-on display causes flickering, random reboot (not often, once or twice a day i believe) and the biggest problem is the region lock, although seller told me three times it was unlocked...

Thought I was the only one.

Yeah, i am thinking of returning it, selling is not very clever... So you think these issues occur cause of region lock? Or every china model flashed with oxygen os? I believe some parts of system must be taken from color os, they dont get flashed, and that can cause incompability... Mine stopped making calls after i rebooted few times.

I did hardware test, and the lighting sensor does not work properly, or at all, it is detected but it does not register changes, it is overall with readings. Seems like driver issue or incompability, i suppose if we used the driver from color os it would work, but who can change that?
