(Q) what apk do I need for call screen? topic

4.4.2 call screen has a mistake. In 4.3 and all other TW roms, when the phone is dialing the top part with the name is in grey then turns green once answered. That's how you know that the call was picked up by looking at the phone. Now and 4.4 .2 it stays green the whole time making it difficult for me to know if someone's answered by looking at the phone. So I want to take the apk out of 4.3 and put it into Kit Kat to make that bar green. Does anyone know what apk holds that information?
