or display screens when I am using the phone while it is
charging?

1. Check whether the scratches exist when the delivery-attached protective film is on the
screen. If yes, tear off the protective film and check whether the scratches disappear. The
protective film is only for packaging protection. You are suggested to use a dedicated screen
protective film.
2. If you have replaced the delivery-attached protective film, tear off the screen protective
film and check whether the screen is faulty. If the scratches disappear, you are suggested to
replace the screen protective film with a new one.

brightness may be abnormal.

environmental brightness to bring you the optimal visual experience. If this function is not
desirable, turn it off and manually adjust the screen brightness.
To adjust the screen brightness: Touch Settings > Display > Brightness .
If you think that the screen color temperature is too cool or warm, go to Settings > Display >
Color temperature , deselect Default , and drag the slider to adjust the color temperature.
Check whether the phone is in ultra power saving mode. In this mode, the screen becomes
darker, and you can only use the call, messaging, and contacts functions. You can touch the
exit button to exit ultra power saving mode.
