2days ago my rog 3 phone started fading out colour from top , after the night I saw 15% of my screen is black . Tuch and mobile is working 100%, I never dropped my phone , there is no sign of damage from outside after throughly inspection I saw a very minor crack inside of the display on top left side. Don't know how it's done.and today around 50% (top half) of the screen is black. But phone is still working just fine no issue at all other than this display.
I am still using it with one-handed mode but if the dark area keep spreading then i have to go for replacement .My phone is just 2-3months old will It be covered undern warranty
