I upgraded to the note 4 when it was released at home I have horrible reception when I had my S4 I could even talk on my phone in the basement without any issues. It gets real frustrating when you rely on your phone and how changing from a s4 to the note 4 there is that much of a reception issue. I like the functionality of the note 4 just wish the reception was as good as my S4 with being the fire chief I use my phone a lot at home the Internet works flawlessly at home just can't make voice calls with out getting frustrated and if your lucky you might have a 5 min conversation before it loses service. I thought it might have been the phone so I went to the store and exchanged for a new note 4 still same problem surely there is an update to fix this problem.
