My Lte connection seems to be worse indoors since I flashed the NC4 modem and rebooted twice. Oddly, I can get decent 3g when docked into my samsung smart dock. I only get teased with 4g status when un-docked. What I mean by that is it connects to Lte but when I try to utilize it with an app it goes dead and returns to 1x. Should I try flashing an older modem, perhaps MJE or MJ7?
