Question Reboots - Asus Zenfone 9

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.

Are you on the latest update? Mine hasn't arrived yet, but I'm worried this issue will appear on mine.

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
Hi all, I bought an Asus ZenFone 9 from the UK online store. I started to migrate the apps from my old phone to the zf9 and once I finished I started to use my new ZenFone 9 as my main phone. However, I noticed around 3 dso that when i wentato unplug a fter charging the phone it looked as if it...

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)

Anyone else experiencing sleep of death?

I have been using my AT&T black Lumia920 for about 2 weeks now. It runs Portico out of box (maybe, dont actually remember). I have been a WP7 user since launch so I know how windows phone works.
The first 3 days on Lumia 920 were fine, everything went well, however starting from the 4th morning I noticed the phone wont wake up by pressing the power button, nor did the alarm sound. I had to soft reset to power up the phone. So simply it's sleep of death. This happens every night and occasionally happen during day time when I leave the phone for a few hours.
4 days ago I cant bear the problem anymore so did a hard reset then flashed Rogers ROM on it. However after I reinstall some of my previous apps the phone wont wake up again. I looked into the backgroud loading apps and uninstalled Engadget, the phone did make it to the next morning. However after I got a few other apps from the marketplace the phone is dead in mornings again. I cant figure out if this is an app issue or system issue this time.
Anyone else having this problem? Should I request a replacement phone?

I have this same issue but I on;y have it at home where cell signal is garbage.
If I'm at work (in the city) i have zero issues.
If I work from home the phone will SOD more than once in an 8 hour period.
I'm curious, do you have a strong signal all of the time?

Signal is medicore at home where I charge, I use the phone a lot during the day so I cant really tell if SOD happens when siganl is good.
I don't think it has to do with the Signal. Me and my wife both have the Lumia 920 on the same Network, my wife never had this issue, I have it almost every day... I'm currently trying to get a replacement.
that happened to me once or twice before flashing portico, after flashing it never happened again

I've had this issue, I really never payed too much attention to it but its happening more often lately, with my wife having power button issues on her iphone 5 I began to think that mine was too having the same problem. But I can actually feel the button clicking which is something I can't feel with my wife's phone.
Nokia store updates to blame?
I've been having the same issue since I bought the device. It only wakes up after pressing the VolDown-Power combination.
My device has been running the Portico update out-of-the-box (8.0.10211.204).
To see if I could pinpoint the issue, I have been wiping my device and start all over. The wipe has been done last Friday night.
About 30 minutes after initial installation it prompts me for 6 Nokia updates:
* access Point
* network+
* accessories
* audio
* display+touch
* extras+info
This time, for the first time, I have NOT applied any of these updates, and until now it has not hung.
Another thing I noticed in the past is that when I disconnect from the charger (either cabled or wireless) it makes a sound.
After applying these updates in the past that sound was gone.
I will see if my phone keeps working throughout the week and then install the updates to see what happens next.

I tried the same, didn't work. Then what I did was uninstalling each one of those apps (my update list was bigger but some i couldn't uninstall as they were system settings) and then installing them back on the device instead of updating. No "SOD's" since, and i've had a lot. Hope it stays this way Either way I'm hoping the next update from nokia will fix these kinds of things.
Cheers!

I have the same problem but I think that is related to notifications, after uninstalling apps that used push notifications the phone last longer before it goes to SOD. If I use skype and whatsapp a lot the phone SOD more often and more frecuent too when I have it in my pants pockets.
I've never tried not installing the updates and the phone is wih the carrier so I can't test
I had several issues with this, and here on the forums I have made several posts thinking it was because the Keep WiFi on. But it is not!
I think it might be Battery App related. Or some other app, as some1 noted, possibly because of push notifications.
I had the last SOD several days ago, I have turned on Keep WiFi on, no SOD so far, yet before it was like several hrs after it was turned on. Also, I had overheating of the device on 2 occasions, then I have uninstalled EverNote, and everything worked fine. Again 4-5 dasys ago I had the second overheating issue, and the phone was in stand-by whole the time, I turned it off, waited 30 secs, turned it back on, no issues so far.
So, for now I cannot say what the trouble is except it is NOT OS related, it is APP related (probably an app with push notification).
The solution? Pretty unpopular, but that is the only 1, except for hard reset. Uninstall all the non-system apps from the phone, and install them back 1 by 1, and testing each app at least 24 hrs.

In the last 3 weeks I had 1 SOD, that last one 8 days ago. And that happened very strangely, I have received an email (heard the sound), and since my phone was in my hand I immediatelly pressed the power button, and the screen didn't come on. Tried 2 more times, and I knew what happened, so I did a soft reset and that was that. From that time, no SODs.
Is this issue limited to certain ROMS or non AT$T models? I have had mine for 3 months now and have yet to have the SOD and I have even recently ran the OTA update and still no SOD two weeks after that OTA.
I got the same issue with my Lumia 920 (European network/sim unlocked). Happened once after night and already twice during the day... . Phone has all latest updates installed... no idea what to do...

Review what apps u have installed. I think I have proven that it is push, and app related. Possibly even some battery app is responsible for this. Try uninstalling some apps, and to see what will happen.
Well, basically I got my phone back from the carrier it passed 5 days of monitoring without SOD and after 24 hours in my hands it happened. I did a hardreset to my phone to clear all my info before giving it to the carrier and now I'm sure that is some kind of app or at least a function that isn't often used by the OS.
I don't know if a flash could fix the issue since not everyone is experiencing the problem.
In my case it seems that the issue is increasing in its frequency...
I think I will have to go to Nokia Care Centre
1308 update seems to have solved this issue. At least 4 me.
My phone does not show any updates available
Got my phone yesterday and today it was in SOD. Luckily I woke up earlier than planned. Have a meeting today and things like this is fatal.
I need to be able to rely on the alarm on my phone.
Is there some way of disabling push notifications for apps, like in iOS? That would help a lot in this case, as it seems it's caused by push notifications.

[Q] Frustrated with desire x

I have posted before too on this issue of random reboots on desire x. It seems that i am the only one who have faced random reboot problem multiple times a day( varies between 1-10).
Now i would like to explain my issue in detail. These restarts DOES NOT occur when i am using the phone and running multitude of apps.
It only occurs when the phone is lying idle or when charging. Sometimes it reboots with white HTC screen while sometimes it gets stuck on a black screen( not switched off), in latter case i have to long press the power button to reboot it again. I can't even leave my phone alone while charging because it may crash which will result in missed calls and messages. The phone worked fine for first 4 months of purchase so may not be hardware related. I did upgrade my software twice from 1.18.401(factory) to 1.18.720 . the latest update was 1 week before the problem started.
I did not spent my $400(Indian price) on buying a buggy phone which bothers me and left me wondering why is it behaving so strangely.
The trouble shooting i performed in last month includes -
FACTORY RESETTING 5 TIMES
RUNNING PHONE WITHOUT SD CARD
RUNNING WITHOUT ANY APPS INSTALLED
PUTTING A WEDGE ALONG BATTERY TO ENSURE GOOD CONNECTION
SCRUBBING BATTERY AND PHONE CONTACTS
USING PHONE ON SEVERAL SIM CARDS
The problem may be network related, i don't know.
I am so disappointed in HTC. Is anybody here on software version 1.18.720 and not facing problem of reboots. If the update is faulty HTC should come up with another one.
I am on a sabbatical and 300 miles far from nearest service station for another month.It makes no sense to cover 300 miles and spend hell lotta money just to get this goddamned thing serviced. My last hopes are on Jelly Bean update to solve this problem which seems to take forever in coming to Asia. Is there any way to go back to 1.18.401 which came natively with my phone or some other way to resolve it.
Thank You
Get it replaced in Warranty. THE JB UPDATE WONT SOLVE THIS ISSUE. As it is specific to some users and not others, so its not a SOFTWARE issue. Its Hardware Fault. Get it replaced ASAP.

Let the warranty guys wonder why the issue happened. Its a costly thing, and warranty is EXACTLY for these type of situations. USE it.
Just save yourself the hassle and get it replaced like nexus suggested if you dig into what the causes are it will take a while because i tried to with an older htc device
Jb wont solve it, if its kinda similar to my problem described in your previous thread, motherboard change is the only option
thanx everybody . so that means i will live with this faulty device for sometime more till i go back to my work place n have access to service station

Thats awfuly bad luck... cant you send it via mail to service centre? In czech republic, there is this posibility (and we are around monkeys level here in whole smartphone situation).
I also have 720.3 but don't have such problem.
That's absolutely a hardware problem,take it to service center asap n dont wait for jb update.

YEA may be i can but that will take forever in India to get a proper response from main htc office/SC that is 3500 miles away. I will be in bangalore in may/june so will directly go the main service centre myself. Additionally I don't think they will replace the phone immediately so sending over mail will be useless if i get the same phone back with some temprory tweaking from their side.
I have 6 months of warranty left till November so if it goes bad let it be, my case will get stronger.
Can i flash my phone back to 1.18.420 myself without voiding warranty.?
In future i will think twice before going for HTC
i read somewhere in forums that android phones also need to cool down for sometime and periodic reboots or what they probably meant is switching off the phone for few mins is essential for long life of the phone but may be its just me

thats old desire trick called "put that brick into freezer", but it doesnt help in long term, youll have to cool it whole time youre using it
RANDOM REBOOTING devices with STOCK ROMs have FAULTY HARDWARE.
I phone shouldnt reboot on heat even with extreme use, and if it does, its faulty.
If you have custom roms or kernels, then it might be due to software issue, but on STOCK, its always HARDWARE.

You remember me about my old Mio A701 phone who started to behave strange for month or two... and after that the radio chip crashed...
Also it happend on my wife's LG phone that a little dirty (mettalic I think) on circuit inside right behind the power plug was able to freeze the phone and some times to restart.
So, if you tried all that things and the problem is not solved then it is a hardware problem! You have to disassemble the phone and repair it! Or go to service center (never I had).
its not a heat problem coz .i can use this device for prolonged sessions. only when the screen is off and network on it reboots
PS. when is jb coming to India
Try one more thing there is a app(don't know name) which can increase the minimum processor frequency
Try that out may be your CPU has very low min speed, don't sure about this but give it a try.
If that requires rooting then don't do it.

[Q] Help LG-P760 frequent crash

LG-P760 stock Android 4.1.2
Only basic apps, FB, gmail etc.
1. Factory/hard reset
2. Works around 3-4 days perfectly, then starts to crash.
By crash I mean black screen, nothing helps, only battery pull.
3. After first crash, starts crashing more frequently. Happens only in standby.
Worst was today: If I start phone, log in, then it wont crash before I put it in standby. First time in standby, within 30 second, it had crashed.
twice crashed when someone tried to call me. Vibrated once, then crashed.
I would like to avoid replacing my phone.
Any ideas how to find the source of this problem? Any recommendations?

I had the same problem with Vietnam Rom and it was the baseband. I changed to the baseband from ICS from a Rom of my country so I have Vietnam Rom+Original ICS baseband and everything works well.
Thanks.
Although, I understand it mostly is problem when you have unlocked bootloader.
I am running stock everything.
And they have problem with rebooting phone, mine crashes and freezes.
Weird is that it starts around third day of normal use.
I think I have to take on a quest with a warranty. Does anyone know, can I contact LG straight without the provider, where I bought the phone?

And they have problem with rebooting phone, mine crashes and freezes.
Weird is that it starts around third day of normal use.
I think I have to take on a quest with a warranty. Does anyone know, can I contact LG straight without the provider, where I bought the phone?

I haven't unlocked it. The problem was the same: SOD sleep of death, when the screen goes off you can't do anything but pull the battery.
But if you can use the warranty use it. You should find the warranty info in the box to know where send it in your city.

Thanks. I will search into it. Sleep of death is new expression for me.
I only have phone, it came from relatives who threw away receipt + box.
Luckily I managed to get new receipt from provider yesterday (I dont think they usually give out receipts twice), so now I can use local warranty.
Thanks everyone for replying. I will post update when I have final solution.
Since you are stock you might want to consider flashing the kdz to see if that helps. Good luck!

I'm having the exact same issue with mine. I've heard everything from "try a different SD card" to "factory reset," and nothing seems to permanently fix the issue. What I've found kind of sort of works is just reboot it a whole bunch until it finally comes up and doesn't do it any more. From there, I'm good to go until the battery runs out or I need to reboot it because all the bloatware is causing it to glitch. This usually means that I have to reboot my device 10+ times in a row every few days. Hopefully, you found a more viable fix than this.

Hi
I managed to kind of solve this issue. Because I am not sure how, I haven't closed thread yet.
Anyway, I warranted device, they re-installed soft. Came back, same thing. After around weeks use, SOD. Factory reset. After that, things went interesting.
I tried not to leave it idle. Always had something running. I also had noticed by the time it never occurred when it was plugged in or music was playing.
One day it did it again, but I was in a hurry and just disregarded it. I did something(I was busy, maybe just plugged it in automatically?) and it came back up. It took like 10 sec for screen to start, but it did just wake up. And it haven't had crash ever since. I have no idea is this solution or is this just some coincidence and I am not keen to factory reset again, to see will it reoccur. It's my only phone
TLDR: Managed to get out of sleep of death, haven't reoccurred since.

Random Reboots

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...

S21 crashing/rebooting 1-2 times/day. Any tips on troubleshooting?

I have as SM-G991U (256 GB S21 US version, stock everything but using Nova Launcher) that is randomly freezing/crashing then rebooting on me 1-2 times/day. Does android have any kind of crash log I could look at to try and figure out what's causing the problem? On the samsung forums, their support reps suggest running in Safe Mode, which I have, but it's not very useful because I can't reproduce the problem on demand and it usually happens 1-2/day, but sometimes less, so unless I just ran in safe mode all the time, that wouldn't tell me much. Plus, it would only tell me it's an issue caused by one of a hundred or so apps which, again, is not helpful.
So I'm hoping there is a crash log or something somewhere because I have no idea what triggers the crashes. The other night, it was sitting on a wireless charger, the screen wasn't on, then all the sudden it rebooted. It's not specific to any app or anything I'm doing. If there are no crash logs (which would be frustrating and disappointing), any other troubleshooting ideas are welcome!
Look for a memory leak. Typically a poorly written 3rd party apk.
Try clearing system cache.
Make sure auto restart isn't enabled...

Hi mate
For logs info check here and here
You can always flash firmware , using home_csc , to avoid factory reset the phone , if the problem is system related it will help
If is app related
Try booting in safe mode to see if problem goes away...

Thanks! I'll definitely try these out. I tried safe mode, the trouble is it's not really great as a diagnostic because the phone will go from 4-24 hrs between resets during normal operation, and since a phone in safe mode isn't terribly useful, it's hard to keep it in safe mode for long enough to see if that fixed the issue, if that makes sense. And then, if it did fix the issue, it just narrows it down to 1 out of a hundred apps! But maybe I'm missing something. Is there additional information I can find if I run in safe mode that would help suss out the problem?

Thanks! I know how to clear cache but not how to check for memory leaks. Do you have a tool you'd recommend to do that? And I had never heard of auto restart before, so thanks for that. I confirmed that it is NOT enabled (that would have been a face palm moment!).

Is not easy , you just need to be methodic
See if you can find anything useful in the logs first
Reflash firmware , use home-csc , see if it help
Have you notice if the phone fails under any specific circumstances?
If that does not help and if you can really relate the problem with any specific app you may try to freeze or uninstall suspicious app and let it run for a day , Package disabler app is a good option , it is easy to enable or disable app but is not free, you could try this one , is a debloater tool , it allow you to disable app... may be easy that having to uninstall / install by hand
I'm also having the same problem. Had the phone since June, it didn't start to occur until late August, which leads me to suspect it is an update related issue.

I'm glad you posted today, I've been meaning to post again here because I tried troubleshooting and am still having issues. In fact, it crashed twice today when I was trying to send a text message.
I installed one of the log applications (can't remember which one at the moment) but it wasn't really helpful. They didn't seem to catch any information related to a crash even though they were logging data at least twice when it crashed.
Then I tried reflashing using home-csc using ODIN and that ended up soft-bricking my phone (and yes, I followed all the instructions and used home-csc) so I had to reflash everything and do a full factory reset. That seemed to help, reducing the crashes from once/day to once/2-3 days for a few weeks, but now it's back to ~once a day (sometimes more, sometimes less).
So if anyone has any other idea, I'm all ears. When I was reflashing and stuff, I noticed in the recovery mode (or whatever it's called) options that you can look at logs. Does anyone know if one of those logs would have crash-related data or any other ideas of what to try? This is incredibly frustrating, especially that it's persisting after a factory reset. Argh!

So what I tried to do is roll back all the default google app updates. Ex: Android system webview, Google app itself, etc etc. I factory reset it without backing up any apps (but pictures and messages etc), It was working for a few days and then it happened again. Which further reinforces my thinking that my problem is software based.

So I'm curious why you think that means it's a software issue. If this isn't a widespread issue with the S21 and after we've both done a factory reset and still have the issue, that makes me think it could be a hardware issue. Of course, there could be some software incompatibility with an app that most people don't have installed or a bluetooth connection or something, which is why I really want to find a useful crash log (and find it rather absurb how hard it is to find a useful crash log on android, come on guys, it's a mature OS, some kind of crash log seems pretty basic!), because otherwise, it could be a ton of issues and I can't reproduce it. Ugh.
The reason is that the "few days" after the reset and restoring pictures, messages (but not apps) from backup, where there were no crashes at all (where previously it would happen at least 2 times per day).

Got it, that makes sense. I'm on t-mobile and just got an update this morning. We'll see if that improves anything because my device restarted 4 times yesterday
I havent had a crash like this since i disabled chrome and other google stuff, and downgrading google apps lol.

How did you disable chrome and what other google stuff did you disable? (There's obviously quite a lot of google services that can't be disabled)
After the most recent monthly update, my phone has gone from rebooting multiple times/day to once every 2-3 days, which is more manageable but still super annoying. It is incredibly frustrating to me that there are no good tools to troubleshoot a crash (at least that I've ben able to find). Honestly, it's driven me to consider an iPhone for the first time in my life .
My trouble is back... I will be scheduling a fix with samsung soon so I can RMA it
Check the below link. This seems to be a hardware problem which got solved after Samsung replaced the motherboard.
Samsung Restart problem
So I bought this phone for my wife. Since I received the phone, after a day the phone started crashing whatever app she was on and then take you back to lock screen without having to go through a full restart process but it was definitely a restart as you would need to enter your pin again as opposed to fingerprints.
Since it was within 15 days of purchase I returned and reordered another one from Samsung, and to my surprise exact same issue. What are the odds of having two brand new phones having exact same issues.
This leads me to believe it must be a software issue. I just received this 2nd new phone last Friday.
Yeah, I think what I was experiencing was a hardware issue (it definitely went through the full restart process, not what is described in the previous post). And from the link posted by sandystays above, it looks pretty common. I contacted Samsung support and was not impressed at all. They walked me through a number of troubleshooting steps that weren't helpful then had me take my phone to UBreakIFix. I did, they ran a diagnostic and their tools couldn't find anything wrong so they said Samsung should replace it.
Contacted Samsung, told them I had taken it in. They said I needed to take it to a technician (again, right after telling them I just had). They then said, oh, you'll have to mail it to us and you'll get your phone back in 7-10 business days. Their suggestion for what to do for a phone in the meantime? Buy a prepaid phone then return it when I get my phone back (which a) is unethical and b) wouldn't work anyways since they're locked). Ridiculous. They also admitted that this is a very common problem, so I asked why they just won't send me a replacement device if it's so common to which they had no real answer, just "that's our policy".
Eventually, I contacted T-mobile (my carrier) and was very pleasantly surprised. After me telling them the issue and the steps I'd taken to troubleshoot it, they sent me a replacement phone (recertified, but still) that arrived in 2 days. WAAAYYYY better than Samsung. The entire process made me a bit jealous of my wife's iPhone. If she had had a similar issue, we could have taken it to an apple store and not had the whole "our policy is that you have no phone for 7-10 business days" nonsense from Samsung AND the backup and restore process is still way better on iPhones than on any android I've ever owned. How there is no easy and reliable backup/restore mechanism on android after so long is beyond me.
Bottome line: if you have a similar issue, it's very likely a hardware problem (my replacement phone has been fine for 3 days now). And avoid Samsung support if you can!

On the second phone I still have the 2wk window to return. I am contemplating if I should just return altogether. I had bought an s21 Ultra as well and that seem to be working OK.
Two s21+ phones with same issue, what are the odds of hardware problem? But what if it is the entire batch that is bad.

Your issue sounds different to me. Mine definitely fully rebooted, I have no idea what is going on with yours, it sounds like your crashes are locking the phone or something, that could definitely be software. Good luck!
