Any ideas on what could be wrong? I am currently using the Black Edition PACRom for the s4, but the problem also happened when using the standard cyanogenmod. I am thinking that maybe the proximity sensor is screwed up but I am just very frustrated about it. Any help would be great!
I think it is the proximity sensor, I had the same issue and what I did is to replace the glass and making some enlargement near the proximity sensor in order to have more blank space around.
you can see it in the photo.
With stock rom, things goes find, now the screen goes black only if i place it on my ear, but with custom rom, i can not hang up calls even if i press the hang up button, call still continuing.
Sorry, if my english is bad, i am a french speaking.
