Why is the notification bar easily mis-touched in landscape mode while playing games on the Redmi Note 14 Pro+ 5G?

Full-screen gesture is a normal feature of the MIUI system, and the current design involves gesture recognition logic, not a touchscreen issue.
If the full-screen gesture affects your gaming experience, it is recommended to temporarily switch to the navigation buttons mode while gaming. This can improve the experience of unintended touches.
To use the navigation buttons on your phone, please refer to the following steps:
1. Go to the [Settings] APP on your phone;
2. Select [Home screen];
3. Tap [System navigation];
4. Select [Buttons]. Once selected, there will be three buttons (Back button, Home button and Menu button) at the bottom of the screen.
Note:
You can go to [Settings] >> [Home screen] >> [System navigation] >> tap [Gestures] >> turn on [Gesture confirmation] and gestures will only work after they are repeated in some cases (e.g. when playing games or watching videos).
