Green line on screen

[AJ40]

All of a sudden overnight a green line has appeared on the side of screen.

Has anyone managed to fix the error without factory re setting their phone.

Thanks

In my case a similar problem had to be fixed under warranty, new screen.

You could also, again from the main Community page, top right use the search option for green line or panel.

You also have additional Australian government warranty rights. Google "Australian government warranty".
