Anyone have issue regarding Asus ROG Phone 2 screen?
Like I have few lines appear then I off screen for few seconds,it's gone AND the pixel of the screen is huge and obvious. Is it because it is in 1080p in huge screen?
Can you show us a few pictures of what you mean? Based on your description, this sounds like a hardware issue.
I'll upload the photo when it happens again. Cz it happens inconsistently
Please view the video as you can see there's a horizontal white line in the middle of the screen.
After I off on the screen,then it returns to normal
Looks like software issue because it is appearing only on certain screens. Try doing a factory reset.
I would agree with @kchinnavigneshraja , but the fact that the white dot/circle persists when the phone is powered off makes me lean towards hardware.
Either way, factory resetting the phone is faster and easier than visiting a service center, so after backing up your data try that first.
If it doesn't resolve it, then you know you'll need to visit a service center for a warranty repair.
