Phone messed up 3gp video while recording. How to recover?

Question

Android

Friends, help advice. Especially those who are engaged in video processing should know the answer. After recording a video on a phone (THL W100, android 4.2.1), the video file gets corrupted.
I can't capture the moment why this is happening. Before I changed the flash drive, this was not the case. Initially, there was a flash drive for 8g, the video did not deteriorate. But maybe I'm wrong, and it's not the flash drive. Is it possible to open a 3gp file damaged for unknown reasons? Or how to find out the reason why the file is not playing. Here is one of the damaged files https://mega.co.nz/#!cYoBBRhK!NSay0hBmVew_cvtfaimP...
Sometimes video files are partially played.

Answer 1

Change the flash drive back and check if everything will be so bad, if not, then your flash drive is simply broken.

Answer 2

This is clear. I would like to find a way to recover those video files that are already damaged. I do not think that there is something serious, but unfortunately I do not understand the video well.

Answer 3

What brand of flash drive? If it is a Chinese noun, you can safely throw it away, you will have a lot of problems with it.
As for recovery - it is unlikely that it is possible. You need to analyze the file, see what is broken in it. If only the title - you can try to restore, however, if the video data is broken, then you can't fix anything.
