Of course I do not know how they do it, but I do know one thing that if you want to keep your data you have to work very hard. You need to set a unique and complex password or passphrase for your device. Avoid using easily guessed information such as date of birth or common words. Turn on biometric authentication. Many smartphones offer fingerprint or facial recognition as an added layer of security. Consider using these features if your device supports them. Be careful when downloading apps. Only install apps from trusted sources. Back up your data regularly: Back up important data such as contacts, photos and documents. In the event of a security breach or device failure, you will still have a copy of your information. By following these general security rules, you can greatly reduce the risk of unauthorized access to your phone and protect your personal information.
