The Darth Technology Center received a call from Mr. Wang, who had an issue with his Xiaomi M4 after it was repaired. The phone had lost all of its contact information, and despite reaching out to multiple data recovery companies, he couldn’t retrieve the data. After a friend recommended the Dass Mobile Data Recovery Software, which is used by high-level institutions such as the police, procuratorate, courts, and military, Mr. Wang decided to try it. With the help of the expert team at Darth Technology, the contacts on his Xiaomi M4 were successfully restored using the professional version of the software.
Now, let’s walk through the process of how the Dass Mobile Data Recovery Software can be used to recover Android phone contacts. First, you need to download the professional version of the software from the official website: http://download. Once installed, open the program on your computer.
Mr. Wang’s device was a Xiaomi M4 running Android 5.0. Connect the phone to the computer using a USB cable.
