I setup my S10 with android 12 and restored my backup I made on my pc with smart switch. I didn't bother to add my passcode or finger prints because I was having some issues, and I thought I might have to factory reset my phone to see if that would fix it. I know modern versions of android automatically encrypt your data, but does it do that if you have no passcode to encrypt it with? Does it just use a code stored in the TPM chip? I want to know if my data is securely erased after the reset or if it could still be recovered. I should have just added a code before I reset it, but I wasn't thinking about it at the moment. There's no way to encrypt the whole phone (including empty space) in android 12 it just encrypts your data. I looked at apps that said they could securely wipe free space, but I saw alot of complaints about data still being left behind.
