How to repair the color bar on the screen of mobile phone?

If you are using a Huawei mobile phone, I suggest you use the screenshot function of the mobile phone to take a screenshot of the current interface. By sliding or zooming the screenshot picture left and right, you can see whether the abnormal lines in the picture move with the picture:

1. When the abnormal line moves with the picture.

(1) I suggest you restart your phone. If the phenomenon still exists, it may be a design problem of the system and software application. Please feel free to use.

(2) If the developer option or developer option is turned on and the pointer position is turned on, the current touch data will be displayed on the screen, fluorescent tracks will appear on the screen crossed by the finger, and blue crosshairs will appear on the screen touched by the finger.

If you don't need this function, please search and enter the pointer position in the settings, and then close.

2. When the abnormal line does not move with the picture.

There may be something wrong with the screen hardware. Please back up the materials in advance (QQ, WeChat and other third-party applications need to be backed up separately), and bring the relevant purchase vouchers to the nearby Huawei customer service center for maintenance.
