What should I do if there are vertical bars on the mobile phone screen? How can I repair the mobile phone screen with colored bars?

If you use a vivo phone and lines (horizontal/vertical lines, etc. ) appears on the device screen, please use the device screenshot function to take a screenshot of the current screen, and check whether the abnormal lines in the picture move with the picture by sliding or zooming the screenshot picture left and right:

If the abnormal line moves with the picture:

1. It is recommended to restart the device. If the phenomenon still exists, it may be that the system and software applications are designed in this way. Please feel free to use.

2. If the pointer position function in "Developer Options" is turned on, the current touch data will be displayed on the screen, and the touch track will appear on the screen where the fingers cross. You can turn off the "pointer position" in the developer options to view it.

Abnormal lines do not move with the picture:

This situation generally belongs to screen failure. Please back up the equipment information in advance, take the equipment and purchase voucher to the vivo customer service center for testing, enter the official website-My service outlet of vivo, select provinces and cities to inquire about the address and contact information of the local service center, or click the webpage link to search for the address of the service center.
