Phone restart randomly

[P0z]

Has anyone experienced a phone that randomly restarts after the 4.0 OneUi update.

I think I know where the issue is:
1. Open settings
2. Open device care
3. Click the 3 buttons at the top right
4. Click auto restart and turn it off.
I hope this helps.

It's not the auto restart. There is an error message that pops up. I have attached the message

Hi P0z, not randomly no, my phone does however power off several times a day but it warns me everytime when the battery depletes to 15% or lower. This happens several times a day after a full charge with every turn off.

This is my Galaxy S21's big boy bay; permanently attached via "ambelical cord" toy phone. Only difference is the baby is keeping me alive and not vice versa ..
