My phone has 4 vertical red and blue thin lines at the middle. I dropped it earlier but I only noticed it after about 4 hours because it is very thin and only visible against dark colors like black. My phone is ok but the problem started when I noticed the lines. I can't type the letters on the middle and I can't touch anything on the middle because when I do, everything just freezes
When I pressed the lock button it starts to work again but started acting up again after 1 hour or so. I pressed lock button again and it started working again until today, but i'm scared that it will happen again.
Update: When I touched the screen the lines will appear but when I'm not, the lines will fade (not totally disappearing), that's not a problem but I just want to get rid of the lines.
Update: it's been two days and the screen is still working fine
