Hi, I got a MT for Christmas and love it. Only thing is when i call my bank account and switch on the dial pad to input numbers it begins to black out, does it sporadically and stays black for different lengths of time. The phone is not rooted and has a few extra apps installed on top of the already installed ones. Have tried resetting to no avail. Any ideas? Sorry if i'm not in the right place, i'm new to the forum scene
