Duplicate files are very common on mobile devices. They can be caused by several factors, such as the same image taking place twice in the device, the same video being uploaded twice, or the same audio file being uploaded multiple times. They can also be caused by the installation of a malicious program. The most common scenario is the installation of a program that automatically takes screenshots of the screen and saves them. Sometimes, this is done by the app itself and it is not a malicious program. Sometimes, the cause is the result of an error in the code of the program.

A few years ago, duplicates were ignored and stored on the device, but now, with the increase in the number of mobile devices, this has become a major problem.
