i've seen a lot of posts on sprints forums about similar issues, but without a resolve.
My specific issue, is that mine won't work with wifi on, wifi calling on, and airplane mode on, says to turn airplane mode off to make a call. Also, i keep getting the notification to setup the profile for 911, i've set it up and saved it multiple times, tried everything, factory reset, clear app cache, recovery clear dalvic cache, and i do nothing to make it appear, meaning i haven't moved anywhere, haven't lost wifi, or anything, ALSO, when this notification pops up, wifi calling stops working. so i'll click on the notification, save the location, it will momentarily lose phone signal (bars with x over them) then gain 3 bars, if i make a call at this point it works, for a minute, if that, then the notification pops up again, and it drops the call.
I've even tried disabling the app from notifications, there are two apps in the all tab of the app manager, one of them is unchecked for notifications, the other won't let me uncheck it. i've also tried unchecking location in the wifi calling settings where you save your location at, but as soon as the notifiation pops up again, location is checked again automatically. can ANYONE help?
