Encrypt your smartphones with a strong alphanumeric password that is at least 20 characters long. This prevents data from being read very effectively.

Strong encryption is important. A screen lock is not enough and is not the same as encryption. Activate encryption in your settings! Professional mobile forensic software like Cellebrite can easily bypass most screen locks via the USB interface by exploiting security holes or trying to guess your pin. All police departments in Germany have this software. All your data, contacts, call logs, location data, login data and much more could then be automatically collected, processed and visualized via USB. Your encryption password should therefore be particularly strong. Use a very complex pattern or an alphanumeric password for encryption!
But what is the difference between encryption and a pin or password? Put simply, password or pin protection is like a locked room. Attackers can still break through the window or wall to access your data. With encryption, on the other hand, the entire room is hacked into small pieces and scattered evenly across the floor. It is not possible to read out this data chaos without the right key that sorts everything again.
