I have the i9505 and i have flashed it with [ROM]【4.4.4】Google Play Edition 07-17-2014 - Pure Nexus Edition build now available by @Danvdh and i absolutely love this ROM and works like a charm but there is one thing i am having issue with and i cannot say its a bug as looked over his thread but no one has mention it. i can comment or post in the developer thread due to the number of posts i have, however i come here to ask for help.
When I make a phone call, my screen goes completely black and when i try wake the screen up, it would take multiple times and sometimes i have to take the battery out. The call somehow runs in the background, so if i managed to wake the phone, i have to pull the notification down fast to hang up and this is pain in the neck.
I suspected it could be the proximity sensor in my phone, i have no cover or screen protector, i cleaned the screen and still the same. so i ran few tests to check the sensor. phone detects the sensor but it doesn't do anything.
Thank you in advance
