Delete Google and Samsung accounts.
Encrypt data in settings, security (strong protection). Factory reset from settings.
Afterwards clear the system cache on the boot menu.
Pretty sure there will not be anything readable after that.

Which OS version?
Mine is a N10+ running on Pie.
There should be a second page... or it's in another settings option like memory.
Try doing a search in settings for "encryption".

The phone is running android 11.
The search for "Encryption" is not showing anything.
Thanks for replies!
