I can't read the message clearly.

First, see if the brightness of the phone is too high and if the white point value is turned on (this is most likely).

The stupidest thing to do is to restart (power off and power on) or redo the annual setting.

Second, there may be something wrong with the mobile phone software. Please try to delete it and download the software again.

Third, there may be something wrong with the system. See if your mobile phone needs software update.

Fourthly, if all the above methods fail, please use USB cable to connect your computer, and then use some applications to manage your mobile phone (which is a little difficult for you).

If all else fails, you'd better make do with it first, because in this case, you'd better not leave home.
