I am really getting angry about this reception, s6 AT&T, my reception is average at best and there are tooooo many areas where my reception is crap, let is normally 3 bars and then nose drops to regular 4g, I was late in returning in 14 days, so I sent it back to Samsung but they found nothing, but not sure how they test....phone is great in optimum conditions but anywhere less then ideal and areas where my old bb got good to great service is a toss up.....I don't know what to do, Samsung redid the software to no luck....I'm in Philadelphia which has strong lte but this unreliability is killing me.
