I am waiting for my 4th Note 3 replacement! 3 for overheating and this last one is a display issue. I think they keep sending defective replacements. I don't know what to do except keep replacing them until I get one that works! This really sucks. I live in Metro San Diego, 92111 and I think I have seen 4g like 5 times on these phones. Very poor reception and terrible reliability! I guess the worse part I'd the hassle of getting support to actually listen. Last night it took over 2 hours to finally get tier 2 support.. Grrrr...
