Problem phenomenon:
Some games don't support full-screen. There are black bars on both sides or one side of the screen.
Cause:
The screen adaptation ratio of some games is 16:9 or 16:10, but as the screen ratio of phones becomes larger and larger, some games are not compatible.
Solution:
Since some third-party apps do not adapt to the 18:9 ratio of the screen, this phenomenon occurs on models with a screen ratio greater than 18:9. It is recommended that you click Settings > Layout Settings > Custom Layout in the game to adjust the screen ratio. If you have any questions about this, it is recommended that you give feedback to the third-party app. Thank you.
