Xiaomi 1 1u50m can't focus.

Xiaomi 1 1ultar camera can focus within 50m.

Unable to focus. Maybe Xiaomi 1 1 camera has a problem with its focusing function. I suggest you go to Xiaomi's after-sales point for maintenance.

Take a picture with the parameters from near to far to see if there are any clear points. If everything is blurred, it is necessary to consider that the lens is moldy (it is not used for a long time and the humidity is high), and the camera must be fixed. If there is a clear point somewhere, it means there is something wrong with focusing.
