What it is
A checklist to lock down a phone, plus a quick app-permission cleanup.
Checklist
Strong lock (PIN/passphrase + biometrics), short auto-lock.
Encryption on (default with a lock). Weekly OS and app updates.
Why it matters for security
Revoke permissions apps don’t need, like a torch app asking for contacts.
Fewer permissions mean less to steal if an app turns bad.
