It restarted by itself without proper access.

My phone turned off and restarted at the wrong time something wrong I got an error through message Samsung members

Probably just updated and you had a previous notification before the update maybe 🤔

It's an old phone Galaxy S8 Plus I was playing with developer options not sure

[matt_z]

I don't recommend playing around with dev options

[Joshua tree]

Only ones I know about

[VerbumVeritum]

The S8 + is far past its OS and security update lifespan. I honestly don't even recommend using the phone. It is extremely vulnerable to all forms of cyber attack.

I use old Sammy's for webcams or drone viewfinders.
