I decided to make a new thread after what i learned. I figured my issues (black screen always during call, not powering on unless plugged in a charger or battery in and out) were issues of the proximity sensor. I found an app and tested the closest distance and it as 0.0cm. Which I assume means it is always being covered. I recently replaced the screen myself since it was badly damaged. There is no screen protector. Just the regular glass on the screen. What do i do. Can I bypass and disable the proximity sensor? Or what? I emailed the company to complain.
