  1. Is there a way to turn on wifi calling because metro fixes it so it will not work with an unlocked phone on any other carrier, and I know att supports it, but It will not hook up to there system because it says my sim is invalid when it is not, i use my unlocked phone on att for a couple years now.

  2. I have never had these many phone problems ever! Ever since I replaced my screen it hasn’t been the same. Brought a new LCD ETC so my screen won’t come on when I double tap it. And I have it set up in my settings that’s how I would like to turn my phone on and off. Secondly when I make a phone call now smh my screen goes black ASAP! literally I have to press power button so the screen can come on. When I’m on a call I hear my other line beep but sadly my screen DOES NOT light up to show me who is calling me. In order for me too see I press the power button. I’ve done a Factory Data Reset still problem has not went away whatsoever!!!! All my life never have I ever experience this with my screens especially if being a lg phone this is my first time replacing my screen. Will someone please get back too me I would greatly appreciate.

    • Your proximity sensor is not working. At the time of screen replacement, you need to pull the proximity sensor from the old frame and place it in the new one. Open your phone once again to fix the issue.
