S20 Random Reboot - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

after using my S20 for one week, I had some random reboots , I don't know why or what is the reason.

I have random reboots after unplugging the headphones that came with the phone!! Also phone over heats sometimes I never experienced over heating with note 9

Yes, it's done after unplug headphones.

Keep an eye on this

Happened to my girlfriend as well. It's a "feature" that's on by default. Hopefully this is all that's going on. Easy fix: Settings -- Device Care -- ... -- Advanced -- Disable Auto Restart.

[Q] Galaxy Nexus keeps turning OFF

I have a problem with my Galaxy Nexus turning OFF at night.
I goto bed at night and open the clock app and click the screen to dim it. When I wake up in the morning the phone is OFF. I have to pull the battery in order to boot. The battery is fully charged.
I returned the phone after this happened twice and received a brand new one. I have the same problem with this new device. I have changed the power socket and the charger yet still the problem persists.
Is anyone else experiencing similar problems?
I have Skype installed and running which maybe the cause. I will keep it OFF for the next few nights to see if this has a positive effect.
Try it without any off your apps installed. If the problem goes away you know it's an app causing the problem. Then start adding them back in batches until the problem re-occurs. Eventually you'll narrow the issue down to one app.

This is happening to me too.
At random times, the phone will refuse to wake from sleep.
Nothing but a battery pull will fix it.
I don't have skype installed.
Have a look at this:
http://forum.xda-developers.com/showthread.php?t=1360880&highlight=sleep+of+death
Mine started today. Really hope this does not keep happening or I need to return this right away. Missed a few phone calls today and didnt realize until I looked down any my phone was just simply black. Will not wake up or do anything at all. You have to pull the battery. Right before this happened my data was dropping non stop about every 5 minutes for an hour.
I'm trying to stay calm because I love this phone, but between the data drops and the phone turning off im loosing patience quick.
This is happening to me as well. With TWO different phones. The first one I returned to Verizon and now its happening on the second one.
Phone will power off while doing random tasks. The two I've noticed is browsing on the stock browser and texting on the stock texting app.
I'm having the same problem. It's happened twice in the 3 days I've had the phone. It hasn't happened while I'm using it, both times it was when the screen was already off -- it just wouldn't waku up. Nothing short of pulling the battery, letting it sit, then powering on would work.
Couldn't have come at a worse time either, my daughter is in the hospital and I get updates from the surgeons via phone. So now I have to check every 5 minutes and make sure the phone is still on.
Phone is bone stock, out-of-the-box.

it does it when i have skype running too. also i have other other audio apps open. (power amp, tunein, pandora) It's happened twice to me and each time it has been during a skype call while the other apps were running. (in widget form)
shock sensitive in the area right below the camera?
My device just "randomly" switches off (sometimes several times a day). After a long search for a reproducible cause, it seems safe to say that at least some devices seem to be extremely shock sensitive in the area right below the camera (on the back of the device). Even minuscule shocks to this area switch these devices off. Youtube-user 'jardinepatten' demonstrates this problem nicely in a video called "Galaxy Nexus Turning Off".

Random reboot and shutdown

Lately my galaxy nexus has been shouting down or restarting. If it doesn't restart by itself I have to pull the battery to get it to turn on. It should be noted that each time this has happened Skype has been on in the background. (audio only)
Also there are other audio apps open in the background (power amp) that were occasionally playing during the call. I have headphones on also. I'm on Verizon and my nexus is 1 day old. Any ideas how to fix this? Thanks.

Hi there,
I noticed that you mentioned you used Poweramp and I think this could be your problem. I had the same issues: random reboots, and a few times, my phone would vibrate in my pocket and turned off itself. I returned the phone (luckily still under warranty) and received a brand new replacement.
I started to install the apps one-by-one, and within a couple hours of downloading poweramp (which i had also used in my previous device), my phone froze and shut down without turning on. I had to battery pull a few times, and thankfully, it turned on again.
I uninstalled poweramp, and there has been no issues since (it's been 3 days without poweramp).
Hope this helps.

HTC One X restarting randomly!

Hi fellows,
I bought HTC one X in the morning itself, and within 2 hours of purchase was greeted with first random reboot, I've had this phone for 10 hours now, and it has rebooted thrice, with last 2 reboots in 10 min successions when I even didn't touch the phone! Has it to do anything with the software version which is 1.26.720.0..
Has anyone else faced this issue?

See if your SIM card is good and the tray is good closed.
SIM card is good and the tray is properly closed. Called HTC support guy, he told to turn off the phone and turn it on after 2 min. Did that, didn't touch the screen till the phone booted properly. Let's see if reboot happens again.
btw, I was playing teeter which came preinstalled, and that game was lagging! I assume ts pretty light weight game, but still the lag!!
Have to keep to recharge the phone for 8 hours? i.e. the first recharge? Is your device extermely hot? Because sometime overheat tend to reboot the device. Let the device settle down then you can start playing games.
Two more reboots
@ShyamSasi
I did charge the phone for around 2 hours, till the battery came to 80%
The phone becomes warm (not hot) when I use the camera for a long time. I have played that teeter game for only 5-10 min, and it was lagging.
Turn off the device let it chagre for few hours (Offline charging) then see how it is. Nothing works try do a factory reset the device.

Try to do a factory reset, if the problem keep continues, go back to the store and exchange 1.
Hts reboots
I had the same problem and i fully charged a couple of times with the phone off and the battery completely empty and now i have had no restarts for 2-3 days. Hopefully it's gone. Are your phones still rebooting ?
I've had my phone reboot randomly once.
Was using my desktop, then suddenly heard a sound, I thought there was a notification but the phone just rebooted.
Never happened since I got the phone (only about 3 days).
Mine is white and made in Taiwan and running on 1.26xx
Just sharing,
Cheers
not had a radom reboot at all

no restarts here had phone since tues
Whatsapp user and never had a reboot for 2 weeks. Suggest you bring to the store immediately.

Same here - Sense restarts more frequently then phone restart, so it seems like a memory leak/resource issue. Phone has restarted by itself twice in 2 weeks, once it detected a 'crash' and requested I send log. Other time it didn't. It is definitely warm when it restarts so maybe temp ahas something to do with it.
Try disabling fast boot in settings, then restart your phone
Reboots are also caused by SetCPU, in case you use it.

Seems to have made a difference. Sense restart only once in the morning. Wil monitor for a few days. Thanks!
I have had several restarts, all of them while listening to music. Either through the music player or using SR Play (Swedish radio streaming app). With the music player I had the head phones connected. With SR Play I was streaming the audio to a bluetooth device.
Anyone else experienced this?
I had a restart too while listening to music through the ear phones with music controls that i got with my Desire s. That was 5 days ago and not happened since although playback does make a click/pop sound every now and then.

Random Reboots?

I was just wondering if anyone else has an issue with their Note 4 rebooting randomly with no external input. This started happening with the Android 6.0 update both on the download from here and the AT&T official release, Any Ideas? I've already purchased a new battery due to a separate issue, any idea?
I had the same problem. The phone would freeze and randomly reboot. Sometimes the system crashes and asked me for the typed-in password (not fingerprint). Sometimes when I charge the phone, and unplug the power cable, the charging led stays lit and the battery has to be pulled. I decided to switch the battery with my wife's Note 4 and see if the effects remained. So far I haven't had any problems after switching the battery, so I believe the battery may be the cause of all these issues. I'll keep you updated on the issues.
I'm back. The battery replacement didn't fix the reboots. I think my phone's hardware is permanently damaged. :crying:

can you downgrade to Android 5.0.1 and help me with my problem?
its something completely different to this topic
I've been having the same issue, started about 2 weeks ago. phone would start being sluggish then if I continue tapping on screen, it'll reboot. At least once I saw it go into recovery & reinstall firmware(?). Another time it just sat at the bootloader screen waiting for software download or something till I took out the battery. Most likely it's a software issue related to 6.0 update or updates afterwards. taking out the SD card helped a bit.
but basically got annoyed & upgraded to LG V20 today. Coincidentally, there was another person at the AT&T store with a Note 4 having the same issue.
Mine just rebooted twice on me a while ago, first is emergency calls only now the reboots then what. And yes the slow charging is a problem too. MM got serious issue dam att

use wakelock its an app u get it from play store.it makes ur cpu always running.some how it fixes the problem of random reboots. dl it and set it to partial lock (the 5th option)
Same problem. Just started a few weeks ago. REALLY frustrating having to enter my password every 3-4 minutes. NEVER buying another Samsung, too many damn issues with this phone.
My reboots tend to happen once the phone goes below 60% battery. It's fine above 60%. Once it goes below 50%, the reboots tend to happen with any intense network activity. The phone will often go from 50% to 22%. I forgot what the 30's and 40's look like. I will try the Wakelock app.
Ugh. I posted about this a few weeks ago. It's started happening more frequently and will occasionally go into a boot loop or show 0% battery even though there's a charge.
Has anyone found any solution? I haven't tried wiping / resetting but I'm getting close to trying it.
Here is a cautionary tale for you. My completely stock, unroooted phone started acting the same exact way. On the 4th or 5th battery pull (to fix a frozen screen) it just crapped out. It's totally unresponsive. Deader than a door nail. Tried everything. The download mode, discharging by power button depression/battery removal, etc. Adb shell command does not detect it. Nor Odin. Computer throws up a qhsusb_bulk error when I plug it into pc. I have NO CLUE how to fix it & I am desperately seeking a solution. Please proceed wisely with your oddly acting phones & don't let this happen to you.

Same issue. Just got off the phone with Samsung support, all possibility of having this particular phone with this particular issue sent in for evaluation has been suspended. Translation, they know it is an issue and will not stand by the changes they push to their products (latest OS). I am researching the prospect of legal action since THEY pushed the new OS against my request. Shouldn't that affect the warranty or coverage? Consulting my attorney friends as we speak. Will let you know. I am not sure how WakeLock will help, it is not going to sleep, it is repeatedly power cycling through a kernel process until the battery overheats or it reboots.
Same issue
Since Marshmallow, my 910A will get sluggish or freeze, shut down, sometimes reboot and sometimes just brick (temporarily). Sometimes--more often in recent days, I get a "dll_mmc read fail" message and the target that says do not stop downloading. No matter what I've tried--factory and soft resets, cache clearing, battery pull, replacement, and SD card switch, contacting AT&T and Samsung rep--it doesn't seem to change. This is a daily issue and becoming more frequent. Any suggestions or do I just need a new phone? Thank you.

Note 2 keeps restarting everytime!

Hi guys. A relative asked me if i can repair his note 2. I think his network was locked and the phone keeps restarting everytime. I flashed a new firmware on the phone. The one I use on mine..XXUFNG1, and also I went into recovery and clear data and cache after flashing. But still the phone keeps rebooting everytime. Why is that and how can I fix this?
Note : It's not bootloop or anything. You can switch on the phone, use it for like 5mins and then it freezes and restarts itself. And it goes on like that. Sometimes it doesn't restart also and you can use for more. But most of the time after 5mins, it restarts.

Everything stock..like I said! Before flashing to the newest rom too, everything was stock.
Was the phone dropped or exposed to moisture? Possible battery problem? Reboots even when connected to a charger?

Hi..thanks for reply. I tried another battery in it. The one I use myself. But it still restarts. I don't know if the phone was dropped or anything though. The relative just told me that it needs to be unlocked. Do you think it's software related? Or something is damaged in the phone?
Since it is running a stock ROM and still behaves this way after a factory reset, I think there is a hardware problem.
I might have a similar problem. I copy from another thread:
Hey guys,
I like this rom so far. But since 2 weeks I got an issue.
My phone randomly turns off, atleast I guess that's what happens. Sometimes the "notify" LED is on permanently but the display won't go on. To start the phone again I have to put out the battery and put it back in.
My battery is randomly empty pretty fast even if I just let the phone turned off. This happens like every 5 minutes.
I already bought a new battery but the problem hasn't changed.
What to do now? :>

I like the phone. It's over 5 years old and runs like the first day. Except it DOESN'T wake up anymore after a short time when the screen is off. I can press the power/home button as many times as I want and wait for 5 minutes, screen will still be off. Only way to "wake" it up again is to put the battery out and in again.
Currently I don't have enough money to buy a new phone and I can get a new motherboard for 25$. But I'm not sure if this will fix my problem.
I'm not even sure if this is the ROMs problem since it worked with all earlier versions of this rom perfectly and even the latest release worked for weeks/months.

As long as I leave the screen turned on the display/phone won't go off and I can use it as always. Even the battery don't drop drastically then.
It might be exposed to moisture tho. When I take a hot shower I'll leave it on the window sill and the room gets steamy.
ROM: [7.1.2 r24] LineageOS for N7100 [Unofficial] - Version from 08.10.2017
GAPPS: Open Gapps ARM 7.1 Aroma - 03.05.2017
Baseband: N7100XXUFND3
Ril and other stuff I don't know where to check.
Some years ago I had the SDS and the motherboard was changed without the EMMC bug.
Sometimes my phone only charges in slow mode too.
I try a clean install and newer pico gapps now. Maybe it will solve the problem. I'll reply then if it worked or not.
[EDIT]
Since my phone was low on battery I turned it off completly and put it on the charger. After an hour or so I wanted to look after it.
The green charging light stays on and if I want to turn the phone on nothing happens. The light stays on even after removing the charger.
Seems like a hardware, not a rom problem? Will changing the motherboard fix this?
[EDIT 2]
Quick update. I fully wiped/factory resetted and clean installed newest version of this ROM + newest mini pico GApps. Still the same problem. Gonna try it with another ROM/kernel now and if the problem persists it's a hardware fault.
[EDIT 3]
Fully wiped again and changed ROM+Kernel. Still the same problem.
