S22 keeps rebooting

[patc7]

Hello, I purchased a S22 in September, from the start it kept randomly switching off and rebooting and not coming back on for a couple of days. I sent it off for repair with Samsung but was told no fault found. It keeps doing it not as bad as it was as usually comes back on within an hour.  Anyone have any suggestions over what could be causing this? Thanks!

Depending on the Terms and Conditions of any relevant cooling off period in your region you reside in, if a phone is showing faults out of the box i.e straightaway I would have asked for a new replacement.

A person shouldn't be expected to have a Repair carried out / Service Centre inspection on a brand new phone 🤔

That said if you decided to wait out the issue and went passed the cooling off period then Samsung will offer a Repair / inspection.

If you used Smartswitch to move your information from your previous phone to the s²² then may I suggest to factory reset ,and then set your phone up as a new phone, and then use your Samsung Cloud [ if you've backed up to this ] and then see what happens.

Or if you do not yet have a Samsung Cloud Back up then download your apps manually via the Playstore and your MyLibrary.

Other information like contacts maybe in your Gmail if you use that or via other means or manually input them.

Also a person can try these generic troubleshooting guides.

• Safe Mode  > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict. 
• Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too. 

If I can be of any further help then please don't hesitate. Take care.  😎
