Why does the touchscreen in other areas become less sensitive on the Redmi Note 13 Pro+ 5G?

The Sidebar function is a normal system module and is not a hardware touchscreen issue. If this function affects the touchscreen experience in certain scenarios, you can press and hold the sidebar and drag it to another position.
If you want to turn off the Sidebar function, please refer to the following methods:
1. Open the [Settings] APP;
2. Navigate to [Additional settings];
3. Tap [Floating windows];
4. Enter [Sidebar] to turn off [Always show].
