I can't open files received from other devices.

Question

When I send files from another Android mobile phone to my device, I can't open them. It says "file format not supported". Why is this happening?

Answer 1

This error is encountered because it's possible that you don't have an application that can work with the file types on your device. To fix this, open the files on the sender's device. By doing this you can see what application can work with the specific file types. After you did this, download the same, or a similar application from Google Play. This should fix your problem.
