[JHumphrey]

Hi guys, i need help. I broke my phone screen so i sent it to repair. I got it back and now i recognized that i have some weird shaped rectangle on my screen. Is there anyway how to fix this without buying new display?

If you sent it to be repaired, at the dark part wasn't there before, the place you sent it in to for the repair should be fixing it. Have you contacted them?
