[Q] Please Help Galaxy 10.1 Screen Closes every 15 secs - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

I bought a Samsung Galaxy Tab 10.1 on September 13 in the USA. It is a 32 GB WiFi model. And it was shipped to India and I opened it on the 1st of October.
This is what happens:
I can switch on the device
The Home screen appears.
And without me doing anything or if I try to explore any of the widgets the screen goes off and then comes back again to the Home Screen itself. All within 15 seconds.
And if I try to press the camera option it say "Please turn off USB storage before using the camera function"
I tried to meddle with the settings( all within 15 the seconds as it again shuts off and goes to the start home screen) but to no avail.
But I'm able to shut down the device.
Buddies it is a brand new device , I did not even register myself , no data loaded , nothing at all. I think it is some software glitch.
Since it is an imported piece they say it cannot be serviced in India.
HELP ME

What model have you got?
Two choices with a new electronic device - faulty hardware or faulty/corrupted software install at manufacturing.
If you cannot return it to where you bought it (India>USA must be tricky) you can only eliminate the software possibility by re-installing from scratch...if it works then ok, you're up and running....if it doesn't then it's hardware and you're gonna have to find a way of getting unit repaired/exchanged...sorry can't be more help with instant answer...we can help you on this forum to try a reinstall, no problems
If the unit really is knackered, and you don't get anywhere with local support, you could try what I have tried on occasions with spectacular success...trawl the web, find the name of several top people in the company's head office - by this I mean in Korea for Samsung, draft a message stating faults, what they have not done for you in your home country as regards product support and then emphasise that you believed Samsung to be above this sort of shoddy standard, say how you thought they were a reputable company etc. Don't be rude but sound despairing and disillusioned with the company....."customer service" people could not give a toss in most countries, thay are paid their salaries regardless of whether or not you are happy Make up every email address you can think of for a name and fire the message off to all of them...hopefully you'll get lucky with one of the addy's...you'll be amazed how rattling the cage of somebody really high up in a company can get results

Try going the custom rom way. Try flashing task's rom and see what happens? If it's still a problem, u can be sure it's a hardware problem

Why a custom rom?? First thing to do is just to see if it is software related...there are some people who have problems with custom roms, y'know...just reload stock first to see whether it is hardware or software problem...throwing new things into the mix should come after a correct analysis of initial problem...introducing another variable straight off is not good practice

A few suggestions. First, in screen settings, make sure the display is not set to turn off in 15 seconds. If that's not it, then try to do a factory reset from the settings screen. The only other I can think of is to connect to your wireless and check for updates.

Checked...it's not set at 15 secs

Please use the Q&A Forum for questions Thanks
Moving to Q&A

Did you try the factory reset like rcy1 suggested?

Yes I tried

I just had one other thought... is the power saving enabled?

@ orthochow
Any news?

HD2 stuck at logo boot up!

Every time I reset or turn on my fone after shutting down, it will stuck at the logo boot up. It wasn't like that when I first bought the fone. Now it's getting worse and worse since the issue happens so frequently.
I have to take out the battery and put it back, then wait for about 3 to 5 mn before I turn the phone on.Then it would boot up as usual.
Is there anyone facing the same issue as I am? Any suggestion guys?
Are you experiencing excessive heat when this occurs? Also, can you give more info such as: does this happen only after recent charging or does it ever happen when the phone has been turned off for a long time? Was there any recent apps you installed or ROM changes when this started happening? Was there any potential damage done to the phone -dropped it, got it wet, or microwaved
When you say frequently, does that mean every time you restart? every other time? every five times?
Lastly, do you have any other issues/symptoms other than freezing at startup? Does the phone ever freeze during normal use?
i'd suggest you do a hard reset of your phone (hold down both vol up and vol down keys while powering on/resetting). that should fix the problem. if the problem still persists, it's probably some hardware faults.
Me too
My HD2 just started doing this too. It was fine for 7 weeks I have owned it. However, as described in this by OP, when doing soft reset would it would also get stuck on bootup logo. I'd have to remove the battery for a few minutes before it would bootup.
However, my HD2 also crashes and upon reboot then get stuck on bootup logo. It appears to crashes randomly eg not with any particular program or action.
I figured it was software issue so did hard reset. This worked fine. After hard reset the only software I loaded were Total Commander and Cookie Editor.
After Cookie Editor install I did soft reset and it got stuck on bootup logo. : (
So I did another hard reset but it hung up again upon reboot on bootup logo.
This appears to be a hardware issue. But has anyone else had same issue?

yes i am experiencing the same problem and i have uploded a video on youtube showing this! Yes my phone heats up when this happens..
Hi. I got this problem for quite sometime and am so used to taking out and putting back and taking out and putting back the batt.
But now I have another prob: my ringtone suddenly went soft and I now have to keep myself alert all the time to see if there's any incoming call or SMS.
I would like to do a hard reset but the question is: will it set my phone back to the stock ROM or still retain the updated version - 1.66.707.1?
Thanks in advance.

HD2 issue
After some more searching it appears this is not uncommon for HD2. Its not clear to me if it is specific to T-Mobile HD2 or HD2 in general.
It appears to be a hardware issue. Although that is not 100% clear either. I find it hard to distinguish what some people report as 'freezing' which i believe is different to the issue described in this post which is 'hanging up' or 'getting stuck' on boot up screen - in my case it is the T-Mobile 'stick together' pink and white screen/logo.
(The 'freezing' issue that i believe is different to this 'getting stuck on bootup logo' issue appeared to have been resolved iwth new T-Mobile ROM - and I never experienced it on my HD2).
The resolution for getting stuck on bootup screen issue described here appears to have been to exchange HD2 (although some people exchanged up to 6 times and keep getting same issue!)
I think it is important to note that my HD2 performed fine for 7 weeks with lots of soft resets, hard resets, and lots of software installs (though no ROM reflashing) but within last week or so, start crashing randomly, then upon reboot get stuck on bootup screen/logo. This also became more frequent as time progressed. After doing hard reboot, the issue is now acute, eg it gets stuck on every reboot, and crashes more often.
This leads me to think some hardware has failed or degraded and is getting worse, maybe a connection/soldering etc?
However, is there any possibility that a ROM could 'degrade'? Can a ROM have a setting that is modifiable? (I know it is 'read only memory' but is it really?)
Anyways, love to hear from others on this issue.
Same problem here. Bought my HD2 in june. Cooked my own rom with Chucky's kitchen. Flashed different radios, hard resets, task 29 etc. Absolutely no problem. Worked fine for several weeks. But sometime it begun to freeze, auto resets, stuck at boot logo. It was getting worse. Even flashing stock rom it hungs at boot logo.
Now my HD2 is out for repair. Now waiting for returning. Hope they will change the motherboard.
several people have had their motherboards replaced and that has seemed to fix it for them. You'll probably have to fight with htc or your carrier, but should be able to get it replaced.
Hi guys. Another question:
I'm considering doing a hard reset. How do I store my messages before doing it? I can't seem to locate the folder that keeps all my messages.
TIA.
HD2 is an odd one
Thanks for replies. I really don't want to send it in .. but it will probably be the only way to resolve the issue. It will cost me courier there and back, and $20 'triage' fee .. total cost to me will be ~$100 just to have them look at it. Price of doing business I guess.
Anyways, I realized that one of my issues was that it was crashing when syncing. A little digging reveals that HTC Sense does something to all contacts when syncing first time putting a bit of html in contact notes field (weird but it is true .. its their way of reminding you bought an HTC phone?) So once I got it up and running, I disabled Sense and syncing went fine, no crashing.
(Btw, Sense also appears to do something with SMS msgs too so if you have lots it crashes on due to this reason too).
However, even with plain Jane MS today screen (eg not using Sense) it still crashed once on sync and again when listening to radio. Both times had to remove battery for few minutes before it would reboot without getting stuck at bootup logo.
But so far it seemed to be working 'better' without using Sense.
So, I re-enabled Sense to see what would happen and over a day it has crashed twice. I am going to see how it behaves for few days before sending it in as RMA repair.
Still, important point is that it was ok for 7 weeks, and then started crashing, more and more, even after hard reset, though some of issues may have been due to Sense (which is reported by many users).
It is still not a 'normal' thing for a $700 consumer device to have such erratic behaviour. So, given others have exchanged crashing handsets for new handset that has no issues points to underlying hardware issues as suggested above eg motherboard.
As comparison I also have HTC Diamond 2 which has been rock solid for 2 years of continuous use even with lots of software install, tweaking, reg hacks, etc.

I don't text a lot so i just hard reset without saving .. but do a quick search on on XDA for SMS backup or PIM backup .. during my searches I am sure i have seen a couple of utilities that do what you want.

Thanks. Btw I read before we can actually 'disable' Sense.
How do we do that?
Sense - go to Today
Go to Start - Settings
- iI you see the black HTC Settings (has 'Personalize' on top of items) then go to Menu and select 'All Settings' (this will show Windows Mobile's Settings. HTC Sense 'Settings' doesn't everything Windows Mobile Settings has or shows it differently)
- Select 'Today'
- Select the 'Items' tab in Today
- Check 'Windows Default' and click OK in top right.
This will 'swap' out HTC Sense 'today' with Windows Mobile standard Today screen and voila you will have 'disabled' HTC Sense and you are back to using Microsoft's Windows Mobile 6.5 version of Sense (not anywhere near as useful or neat-o to look at but hey they are pretty happy with it )

Just by disabling Sense is not going to make it work. I had this problem with my HD2 also and without using Sense it seemed to be working (there were fewer crashes), but only for few days. My HD2 was getting worse day by day - it was not crashing only if it was not touched (it was crashing just cycling between Sense tabs or by initiating a call).
At repair center they told me (after three weeks of waiting) that the motherboard must to be changed.
Is it possible to damage it by flashing custom ROMs?
For me, this problem appeared after just one month of usage. I was flashed some custom ROMs.
Now, I have a new HD2 but I'm affraid to flash a custom ROM (at least in the near future).
I have my HD2 back. Took me 2 weeks, the repair center changed the motherboard and got an new IMEI.
Now all is working, no more stuck at bootlogo.
But i'm on stock rom (1.66) with 2.07 radio. No way to run Android with this radio. Hmm...

I'm afraid as well to flash any custom rom now. For Android i need to HSPL and flash a 2.08 radio or greater to use it. But i'm stick on stock rom for sure.
I want to know as well if it possible to damage it by flashing customs roms ?
As i stated earlier, i flashed plenty of roms, doing task 29 etc., in the end stuck on bootlogo.
Thanks for the feedback on your repairs axman79 and Kalip. Btw, aside from courier cost there and back, did you have to pay the $30 'triage' fee or whatever they call it? Also, did they challenge your observations at all or did they just replace motherboard without question?
Yah, disabling Sense hasn't stopped my HD2 from crashing eith. Without using Sense it crashed several times while using Opera and more than a few times while syncing over the past three days. Also, it still gets stuck on reboot often, requiring battery to be removed for few minutes before rebooting.
So, guess I will send my HD2 in for RMA repair too (and wait for up to 3 weeks) and hope I get a functioning device in return.
Interesting though I didn't flash my HD2 but it went from 'good' to 'bad' in similar way that your two HD2's. From reading other posts around here on XDA and elsewhere it appears that HD2 motherboards fail with surprising frequency and for variety of reasons.
Would be nice to know if HD2 motherboards are unusually delicate and something physically breaks, or if there is some electrical operation, eg charging it on USB or unusual combination of button pushes that shorts something out?
The fact that battery has to be removed for few minutes in order to get thing to reboot hints that something requires charge to dissipate eg a component somehow 'locks up' which causes crash, and needs to be discharged by removing battery?

hey guys. I am so glad I found this post! I have exact same issues ith my HD2, it's driving me nuts.
I kept sort of log and described my problems in this post: http://forum.xda-developers.com/showthread.php?t=712729
I think I have to send my HD2 for replacement or repair.
Can you please tell me how can I get my phone fixed/replaced?
I got the US T-Mobile version, but I don't have account in T-Mobile. Can I deal directly with HTC? Where do I have to call to get RMA number etc.
I would greatly appreciate your help!

Intermittent Unresponsive touchscreen

Okay people, I just got my S3 last night, and after about 3hrs of use, my problems developed. My problem is intermittent, but nonetheless, very aggrivating. When I press the power or home button, screen wakes, but touch is unresponsive. I thought it might have been a lockscreen issue, but I've tried all variants including no lockscreen and have the same problem. Is there any updates or fixes that anyone knows of or do I have a defective phone? Any thoughts are welcomed. For what its worth, I also rooted my device, and it installed supersu. I don't know if that could be related, but I'm going to give a full unroot reset a try as well.

Are you connected to charger, that can cause pro lems when getting unstable current
Sent from my GT-I9300 using xda app-developers app
On or off the charger, makes no difference. I Fully factory restored, pulled root, triangle counter reset, and everything else in between, and the issue still remains. Even tried another rom and kernel, sames results. Seems like I have a fancy light up paperweight for the most part. First samsung phone in over 10 years, and this is what I end up with. Great job samsung.
For how long is there no response.anyway try disable s-voice in settings.that is directly related to home button.power button hmm, don't know..
So, factory reset the phone, reflashed stock rom, even booted phone up with no sim or memory card, fresh from a reset. On the main setup screen, if I lock the phone, then wake it up, touch is dead. Definitely a hardware problem. Called samsung uk because anyone who used DAILYSTEALS.COM will find out if their phone ever needs service, that the phones sold via them came from the UK. Not really happy this wasn't explained on their website prior to purchase, as I would have held off. Now my 3 day old phone with not even 24hrs of use on it is off to a UK service center.
Word to the wise when buying online, check the origin of your phone if the retailer isn't an official seller. now my money saved is going right back.

As stupid as it may be, I want s-voice to work, shouldn't have to disable something to make the phone work properly out the box.

[Q] New Here: Seeking Help w/ Rebooting S4's.

Hello:
So, the bottom line up front is I need help solving a problem with my now third, new Verizon Samsung Galaxy S4--it keeps restarting on its own, at random times, but most often after I lock the screen.
To go in more depth, if you think you may know the solution: I purchased the S4 when it first came out, some time in 2013 (not sure specifically, but it was new) and it worked just fine for 13 months (1 month past the warranty of course); this was back in August, when I got the latest Android update pushed to my phone from Verizon (4.4.2). A couple of weeks later, I would occasionally get overheating warnings that would very quickly disappear (like within a few seconds), and then the device started restarting itself... I cannot predict when it will restart, it's random, but like I said above, it usually happens most right after I lock the screen by pressing the right side button once. I started looking around on the internet for a solution then, but only found a couple of videos from earlier in 2013 where people were having battery problems (Google search has been letting me down more and more as the years pass). One day while at work, I was listening to Pandora as I always have with the phone in my front pocket, as I always have. A few hours later when I got home, not having taken the phone out of my front pocket since those last few hours at work, I went to answer a text message I had received; when I unlocked the phone, the screen was black, except for a small bit of white showing through some cracks UNDER the LCD, UNDER the screen protector, INSIDE my Otterbox Defender... the phone appeared to be working still, but the screen and touch screen did not. At that point I was pretty damn irritated and tried to find answers for a week with no luck... I called Verizon, they sent me on a goose chase to Samsung, who sent me back to Verizon, who got me in a conference call with Samsung and then left the call, and then Samsung ultimately said I would need to pay for repairs to the phone... SO... I went back to Verizon who again said I would have to talk to Samsung, but instead I just settled to giving Asurion (my phone insurance through Verizon, whom I pay an extra $9 monthly) $99 as a deductible to get a replacement S4...
Two days later I receive a brand new S4... spend hours setting it up the way I had my prior one... wasting tons of my valueable time to do so and bandwidth from my Concast ISP and the data cap they've decided to give us... one week later, the phone starts restarting itself... and this one did it more often than my prior one... EVERYTHING is up to date, minus a good amount of useless bloatware apps I never use from Samsung, like "Watch On," which I ignore... but everything necessary, I update. So, I go back to Asurion, who quickly ships me a 3rd S4...
Two days later I receive that third, brand new S4... spend hours setting it up the way I had my prior one... and now, this one is also restarting itself randomly. Interestingly, when I visited family for Thanksgiving, it restarted itself over and over and over much more frequently than when I'm at my place... at my family's place, they have very poor reception, and my phone usually has to work more to try to get the signal... IDK what the deal is, but maybe that information can be helpful to y'all.
Other things to note:
1) When I check the "RAM manager" by holding down the home button and then choosing "Task Manager", the phone is always using at least 800MB of 1.77GB of RAM... even when I choose "Clear memory" and it tells me 30 something apps have been closed... it jumps right back up to 800-900MB of usage.
2) I've tried factory resets on all three phones; with the first one where the screen cracked inside, I hooked the phone up via HDMI... within a couple of days, the restarting begins.
3) With the first replacement I received, I could not sent text messages with the default messenger app... and shortly after trying, it would restart.
4) I have used the same SIM card with all three phones since the issue began, when I first got the 4.2.2 update... I do not suspect the SIM card is the problem, but I'm also not savy with the phone... I know my way around it, but I'm not in the know.
5) I thought maybe it started because of some apps I had been trying, so I had deleted them, and the problem still persists.
6) I constantly have a Pebble Bluetooth smart watch connected to the phone... I have since I got it last Spring (2014).
7) I have never rooted the S4, overclocked it, underclocked it, or modded it in anyway because I do not know how, and I was afraid of what could happen in the future with whatever ROM I did flash onto the device if Verizon tried to push an update to it... I just don't know anything about the whole process, and I'm assuming it requires a lot of know how and babysitting of the device... I just want it to work.
8) I've replaced the battery twice; it doesn't seem to be the problem.
9) I've cleared the cache through the boot manager thing gotten to by holding a combo of buttons on the device while it's rebooting... it did not help.
Edit: 10) Today while I was listening to Pandora in the car, the audio began to skip and scratch, and then it paused for a moment, and then the phone restarted itself.
11) I forgot to mention that the reboot process itself is very fast compared to a manual restart performed by me... the phone will go black, the Samsung color rings will show a second after that, the logo appears then, the screen flashes the red Verizon logo, and then the devices is ready to be used... it's less than 10 seconds.
I've been searching around on the internet for about two months now while dealing with the problem and I can't find anything useful. Does anyone here know what my issue is and how I can fix it? Is there a way to pull error logs / information from the S4 somehow to give to someone to diagnose, like DxDiags on PC? I don't know how to read that stuff myself, but I know it can be very useful... I just don't know how to find that info inside of these very locked down ****boxes we call smartphones...
I truly appreciate any help I can get--sorry I can't offer anything in return; if I can't find a solution, I'm just going to go to my backup phone from 2011 (Droid X), and I will definitely never purchase another Samsung device, especially after they blamed me as the cause of the problem without even seeing the phone...
Thanks.
The problem is with the NG6 software build, and "probably" not with your phone. Go to Settings>About Phone> and see what Baseband Version is on your phone. If the last 3 letters are NG6, that's probably the problem. There is a new OTA update (as of 12/1).....Baseband Version ending in NK1, which corrects the rebooting problem. Either install the new update, or go back to the NC5 baseband version and that should solve your problem. Both NK1 and NC5 can be rooted if you desire.

galaxy alpha issues

Hi everybody i am asking for advice on trying to repair a phone for a family member the phone is a galaxy alpha F variant UK stock rom, factory unlocked and unrooted the problem started after finishing a call the handset was left un attended and when it was later picked up the screen was black but does not appear broken aywhere and does not appear to respond to touch
i have tried un successfully to get it into recovery or download modes the handset turns on and the blue lights come on and you can hear the start up tone but see nothing on screen, it also charges and i have tried a new battery, odin does recognise a device but as i cant get it into download i cant flash a stock rom which i have already downloaded.
So my question is, is there any software that i can download to diagnose whether or not the screen is dead or whether it is a f/w issue or is there a way around this where i can use a different tool to get into the handset and flash a new stock rom in case the current f/w is corrupted
Thanks in advance for any useful help and advice
Please understand that i am a newb to this so if i have made some mistakes or my questions have been answered elsewhere previously i do apologise
I think it seems pretty obvious that the problem is the display itself
Hi BigHands,
I faced a problem having the exact same symptoms as yours twice in the last few month: screen was staying black but phone reacted to some "external" actions (ON/OFF), blue light.
Not sure what happened exactly, but removing the battery and trying to restart the phone finally brought the device back to life after trying more than than 10 times!!!
So in my case, the display was probably not the (only) root cause.
Really weird however that I needed to reboot the phone >10times to make it work: usually when software is screwed either one single power cycle will bring the device back to life or it will never power up again!
Anyways, a FW issue is still a possibility considering the number of bug this phone has (for the price it was sold, that phone is definitely the worse gadget I ever owned!)... But it seems there is a bunch of FW updates on going on this model accross the world, so there is still a little hope things might improve... Samsumg may have woken up; who knows...

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

If is app related

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?

Look for a memory leak. Typically a poorly written 3rd party apk.
Try clearing system cache.
Make sure auto restart isn't enabled...

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!
