I know it's day one and time will tell... But how does the signal strength appear to be on the Note 4 so far? I tried the Note 3 and absolutely loved the phone but I couldn't get or make phone calls from my house the radio seemed to be so weak. The S4 I had also had the same issues, yet my iPhone 5s and my work Casio flip phone both work fine. I have a iPhone 6 Plus on order to keep my place in line but would much rather have the Note 4 if the radio is finally up to par with the iPhone or other devices. Thanks
