Hello all, I am having trouble with my nexus. My text messages fail all the time(well it says they fail even though they go through somtimes) i miss calls and sometimes my phone makes a busy signal sound even though no call is made. I guessing in need the new software that will strenghen the signal but i figured i would ask here. This is my my third LTE device and I never had issues with my Revolution or Rezound so i know its not a service issue. Any ideas?
