I have been a vociferous critic of the Note 3's shortcomings as a communication device. Verizon replaced my first one and signal still sucked. I was skeptical of another Samsung product but, with a business account, I have 30 days to return my new Note 4. It will NOT be going back. My biggest problem was an area where I hunt and since I often hunt alone being able to communicate can be critical. In this particular area the Note 3 had ZERO signal. No 1x, no voice, no text. I checked yesterday with my new Note 4 in the exact same spot and I had -103db of 4G. Not only was there perfect reception for voice and text but also I easily, and quickly, could check email and go on line.
The range of bluetooth connectivity was somewhat better with the Note 3 but I am still experimenting with that. As far as the core function of being first a communication device, the Note 4, so far (and in my experience) is light years ahead of the Note 3.
