New MetroPCS customer. Just a few weeks "in" and already I have two very big issues. I haev been in contact with CS many times and gotten no where. I am LOVING the Samsung Galaxy S3. but I haev 2 MAJOR problems.... One is that the cell signal and 3G/4G SUCK inside my home, but yet is GREAT in any other building I am in (even banks and Sam's club where I would not have service with Verizon!) The answer is that I am smack dab in the middle of 2 cell towers and getting weak signal. No resloution. Have to use Wifi calling app (Joyn) at home and it is is spotty at best! I don't get texts till hours later sometimes. Also, a crazy issue that I cannot use my home phone to call my cell phone. The call does not show up on missed calls, rings via land line end 3 times, silent for about 2 rings and goes to VM. Takes VM 1/2 hour to show up! They cannot figure it out. Metro says its my home phone problem, and Home phone says its Metro issue. Anyone have any ideas? I'm fairly technical and have rooted previous phones following the diections but don't quite understand all the details and inner workings of the cell phones. Not my area of expertise. I've read a bit but still not clear. I am wondering if rooting help my "radio" to boost cell signal?
