This step is crucial to avoid losing important information during mobile data removal.

Log Out of Accounts

Ensuring the security of your personal data on mobile devices includes properly logging out of your accounts. To do this, open the settings menu on your device. Then scroll down to find the “Accounts” or “Users & Accounts” section. Here, select the account you wish to log out of. You’ll see an option like “Sign Out,” “Remove Account,” or something similar. Tap on this and confirm your action when prompted.

Factory Reset Your Device

Performing a factory reset is a thorough method for removing personal data from your mobile device. Begin by backing up any important data to cloud storage or an external device.
