How to Delete the Deleted SMS from Mobile Phone (Samsung SCH-i559)

When the mobile phone is sold or given to friends, most people will choose to restore the factory settings. However, this method is not safe. Some data can still be completely recovered by using some software. The principle of using these softwares is that the data will not be deleted in the process of deleting, only the directory where the file name is recorded will be deleted. If the mobile phone card is full of other useless data, no software can be recovered. (Even if it is restored, it will only restore those useless data. )

If you need to completely delete mobile phone information and data, please press the following methods:

1. Try to keep the memory card, don't give it away, and don't sell it with your mobile phone.

2. The mobile phone is restored to the factory settings. This function, whether it is ios or Android, is within the setting options.

3. After the factory settings are restored, if the original contact information of 500 people is stored on the mobile phone and you want to delete it all, please re-enter the contact information of 500 people. You can find some old business cards and scan them casually. The list of these people will completely cover the original contact information.

The same is true for the complete deletion of short messages, just cover the original short messages with garbled codes.

Deleting audio, video and photos is relatively simple. Download or copy a movie that is large enough to fill the phone's memory with a wifi connection or usb connection. This will completely eliminate the original data.
