hello i have a bush spira b2 10" tablet running android 6.0 that im thinking of selling.
when i look online most people say that i should encrypt the phone and then factory reset it as to not leave any data on the phone.
the problem is that i have already factory reset the phone and not only that but the encryption option is missing from the security menu. the credential storage is hardware-backed.
can anyone tell me why i dont have the option to encrypt even though the manual for the tablet says i can encrypt?
