Default HTC One M7 black screen on during call and end call

I've seen a lot of complaining about black screen during call and end call on HTC phones. Someone verify proximity sensor issues
I have a HTC ONE M7
funny, I have a similar problem, I have tried many ways but unsuccessful, finally i tried removing software HTC Facebook (after rooted) ... and my HTC worked perfectly
I want to verify it is a bug, everyone can try and feedback
