Recently I changed my display myself and after that display goes black when I try to call. But, if I plug my headphone, display is normal. I am not sure which part do I need to fix
Weird that the display doesn’t have the black screen issue when headphone jack is plugged in. Anyway the issue is something is either blocking the proximity sensor at the top of the screen or it’s not aligned properly. Usually adhesive, dust or misalignment of proximity sensor causes this issue.
