WHY DOES IT KEEP RESTARTING BY ITSELF

[caitlin08]

Hi, after having this device for a few years it's only began randomly restarting/ turning off by itself in the past 2 weeks. How do I fix this??? I've tried soft rebooting etc and nothing has worked. Earlier today it turned off and would not turn back on at all until it did (about 10-15 mins of me panicking and holding the on button). This device is the only 1 I have and it is vital for me to have it. 

Any advice will be appreciated!!

Hey there and welcome to the Samsung UK Community Forum

Please go to:

Settings
Device Care
Auto Optimisation

Check if auto restart is enabled....

Does it restart in safe mode? Also try diagnostics via Samsung members app

My One UI 6 S22 Ultra (On May security patch) went into bootloop randomly before 72 hours, then kept on restarting (showing only Samsung logo, no lockscreen) for around 24 hours. Then i tried few button combinations, managed to get into download mode. It showed the Download mode screen and after that it's totally dead. Not even getting charged. I'm from India, out of warranty. Service centre is saying motherboard failure. Motherboard replacement costs Rs.41k (~$500). Not doing it. Samsung must replace affected device motherboards for free, else why would I buy a phone that costs like a vehicle if they cannot provide peace of mind to customers?
