Samsung a8 photography plays '''only in the middle. What's going on?

If the mobile phone/tablet video cannot be played in full screen, we suggest you:

1. When playing the video, check whether there is an icon with arrows on the left and right of a square box on the screen. If so, click the icon to try.

2. Try turning on the screen rotation function.

3. If it still cannot be full screen, it may be a player problem. You can try another player.

4. It may be a problem with the video file itself. You can try changing other video files.
