This is particularly concerning if they are able to perform a factory reset without your intervention.
To mitigate this risk, it’s essential to have security measures in place such as remote device management and tracking services, like Samsung’s Find My Mobile. This allows you to lock or erase your device remotely, ensuring that even if it falls into the wrong hands, your personal data remains protected. Always remember to enable these features during the setup of your device to ensure maximum security.
