Vertical Green line on screen on the right side

[Subang]

Recently a vertical green line appeared on the screen of my S20+5G, tried to do factory reset, but problem did not sort.

Any suggestions

That's Unfortunate. The best bet is to get checked, should be under warranty?

It's more than 4ys, not cover any more.

It could be resulted if dripping phone or software stuff but play safe now to get check and phone repair. Try not to keep it too long

Will do
