To make it nearly impossible for someone to recover your personal data, there are other steps you should take beyond a simple factory reset. Let's see them.

2.a. Encryption of your data. Before deleting anything or restoring to factory settings on your device, it is recommended that you encrypt all your data first. This process will make it impossible to read them without the decryption key. Make sure your device is fully charged before proceeding. To encrypt your smartphone, enter the settings, then "Security" and then "Encryption". It may take a few hours for the encryption to complete, so be sure to keep your phone plugged in to ensure that the process is completed smoothly. It is also important if you have rooted your device to unroot it first and then proceed with the encryption, so that you do not have general problems with your device afterwards. After the encryption, perform a factory reset. If for some reason there is no possibility of encryption on your phone, then use a corresponding third-party program.

2.β. Factory reset. To do this step go to "Settings", then to "Backup and transfer" and from there click on "Factory data restore". All data will be deleted from the internal memory of your device. If your device has an SD card, be sure to remove it from the device before handing it to someone else.

If you have followed all of the above steps then you can safely sell your Android smartphone or give it to a friend of yours.
