Encryption stores your phone’s data in a coded and an unreadable seemingly scrambled form. When you switch on your phone, you need to enter the PIN or protected password, which is the same as your phone’s lock-screen PIN or password, once you enter that encryption key your phone uses your PIN or password to decrypt your data, making it understandable.
Types of Phone Encryption
