I've done a good amount of searching, but if you know of a thread that already answers my exact question, please let me know! (But don't be rude about it ) I have a Samsung Galaxy Note 3 (SM-900T) running 4.4.2 (N900TUVUCNB4). The problem: When the following are set: Wifi Calling set to "Wifi Preferred" Keep WiFi on during sleep is turned ON I'm connected to my strong, wifi signal at home (40Mhz width, 2.4Ghz band) I am not able to receive calls only when the phone's screen is off. Wifi calling features work fine when placing calls, and when receiving calls while the phone's screen is on. Is there a fix for this? I'd really like to use this feature. Thanks!
