Phone keeps restarting A53

[Bill34]

Hi, I have an A53 5g that keeps restarting numerous times a day for no reason at all. There is a symbol that appears on the screen that resembles a cog with a T in the middle. The phone has been checked and latest software installed and they couldn't find anything wrong. Installed my back up on the phone and it all started again.

Have you checked that auto optimization isn't on? The cog is for the system UI and normally appears after a reboot and if you slide up from the bottom of the screen it may ask for your pin if it is set up.

Yes, I've got this issue and found a factory reset "eased" the problem. Should I restart the phone then it will again get caught in something like a boot loop.
Samsung store carried out a flash reset - takes 10 minutes - which for me improved the host of issues I've had since the upgrade. But only temporarily. I'm since told the Android 13 update means my motherboard is faulty so new is required.

Auto optimization will make phone restart

So you should try and switch off
