The SMS screen of Sony Ericsson J20 will jump and blink.

This kind of flashing screen problem has been encountered by many machine friends, and there are too many possible reasons.

It may also be the brightness of your screen.

It may also be caused by a bug in your machine system.

It is also possible that your mobile phone hardware (screen cable) is broken. .

I don't have that machine. What is the reason? Only you can find out. .
