I don't know if there is an option for this in your tablet but it would be a good idea to encrypt tablet in security page.
Required: charged at least 80% and connected to power. Encrypted. Yes it is now fully encrypted. No way to remove encryption except to do another factory reset.
Encryption protected by your pin or password. Electrum wallet also protected by a different password. Created brand new wallet, wrote down seed phrase on paper, showed QR code for master public key and put that as a watch-only wallet on both another phone and desktop wallet.
Bitcoin kinda mooning at this moment, so not really going to spend any, but when I do, I'll make the "change" go to this new wallet. I recently discovered I had some leftover corns on purse, so that's what I used to buy the tablet, getting another one for my wife's mother too, but bigger 8 inch for her daily youtube / netflix, non-crypto watching.
Off-topic: purse is awesome, 25% discount.
