For ordinary users, it is not a good idea to encrypt data using complex encryption algorithms. It adds complexity to complex operating systems. There are two ways to protect your mobile data with a phone blocker. The signal jammer will hide your phone for a short period of time, but the disadvantage is that it cannot use more phones. The second option is naive and does not generate confidential data on the smartphone. Considering that the capacity of a smartphone is basically set to zero, neither of these options is very useful.
