Why is the white stripe of the Sidebar of the Xiaomi 15 not sensitive?

Thank you for your support. The Sidebar on the Xiaomi 15 is a normal system function designed to enhance your multitasking and productivity experience. If you’re noticing that the white stripe of the Sidebar is not responding to touch, it is not related to a hardware issue with the screen. This behavior could be due to specific settings or usage scenarios. To improve the experience, you can try pressing and holding the Sidebar and dragging it to another location on the screen.
Additionally, you can adjust the scenarios of enabling the Sidebar by the following steps:
1. Go to [Settings];
2. Enter [Additional settings];
3. Select [Floating windows];
4. Tap [Side toolbox] and you can adjust the scenarios of the Sidebar. You can also choose to disable the Sidebar feature to avoid interference with your regular touch interactions.
