There are a lot of potential reasons for a green line appearing on a mobile screen.
However, try these potential fixes first:
reset your phone.
Start by turning your phone off, and then turning it back on.
Don’t just turn off the screen, ensure to actually turn off the phone and restart it.
kickstart your phone in Safe Mode.
Safe Mode is a limited mode that prevents anything from launching on your phone aside from the essentials.
This is a good way to see if you have a software problem.
If youve installed any apps recently, try uninstalling them.
If the green line is because of an incompatible or malfunctioning app, removing it may fix your problem.
If youve made any prefs changes recently, try undoing those changes as well.
Check to see if your phone has any operating system updates available.
If theres a problem with your current version of Android, the update may fix your problem.
Factory reset your phone.
This is the last fix you should attempt before you send your phone in for repairs.
If the green line is because of a software issue, the factory reset will fix the problem.
If the green line remains, that means youre dealing with a hardware failure.
Try the non-destructive tips above first.
drop a line to the manufacturer for further assistance.
If your phone is still under warranty, the manufacturer may repair or replace the phone for free.
If it isnt, theyll be able to provide you with information on how to have the phone repaired.
If it’s still black, inspect and clean the charging port for debris.
Let the charge die, recharge the battery, and then restart the phone.
Also, try removing the stylus.
If it’s still echoing, turn the volume down and see if this helps.
Check tweaks to see if your gadget has a built-in echo cancellation feature; enable it if so.
If the dead pixels aren’t getting any better, you may have to replace your screen.
