The white bar on the side of the REDMI Note 13 Pro refers to the Sidebar function, which is a system function. So this is not a screen touch hardware problem.
If this function affects the touch experience, please set up the Sidebar function referring to the following methods:
1. Press and hold on the sidebar and drag it to another position to see if the problem still exists;
2. Navigate to [Settings] >> [Additional settings] >> [Floating windows] >> [Sidebar]. You can adjust the sidebar showing scenes or turn off this function.
