If you are unable to play full-screen videos on Huawei videos, you can solve the problem by the following methods: When playing some video content, the screen has black borders and cannot be played in full-screen mode. This may be due to the following reasons: Reason 1: The video screen ratio is 16:9, which is not the case for full-screen mobile phones.

The ratio is greater than or equal to 18:9, and there will be black borders on both sides when playing in full screen.

Reason 2: Some older film sources have black borders during content production.

You can try to click on the upper right corner of the full-screen playback window: :Set the screen ratio to: tile or stretch to achieve full-screen playback; however, there are very few older video sources that cannot be tiled or stretched due to production source reasons.

Stretching, please understand.

If you still have questions, you can provide the video name and contact Huawei customer service 950800 for feedback and verification.
