S21 5G after update

[mantonton]

After the latest update, my phone will blink after awhile of use, when watching YT full screen, it will had a blink ,then get back to normal view, using Google map full screen, it will get back to home screen, folding small map on right corner. Anyone have the same problem?

A few things to try. 

• Reboot & see. 
• Boot into Safe Mode & see. 
• Boot into Recovery & wipe cache.
• If all else fails, you COULD backup your phone with smart switch & factory reset. 
• I've never had any updates that crew any issues, so I think that it's unlikely that the update caused the issue you described. 
• Last resort, visit a Samsung Service center to have it checked out by a technician.

Hi, we suggest you backup and reset. Here are the steps to backup your data:

Try different way to resetmy phone, but no luck.

Power OFF your phone & wait a couple of seconds, then press & HOLD Power + Volume UP until you feel the phone vibrate. Release BOTH buttons at the same time & wait until you see the Recovery Menu. Use the Volume button to scroll down to "Wipe Data Factory Reset" & Select with the Power button. Wait a few seconds until the screen defaults back to the Recovery Menu "Restart Phone Now" & Select with the Power button. 

It'll take a couple of minutes until the phone boots up to the Welcome screen. 

Your phone will now be as it was when you first received it.
