I have the new Note 4 and I'm sitting in the FTB building just across Hwy 50 from Capital Christian Center where two towers are and I BARELY get a 3G data connection. Also, I sit next to the window that is closest to CCC and can see the tower right across the Hwy. As mentioned in a previous post, the SPARK map is not to be trusted but it does show 4G and SPARK flooded in this area. What am I missing? My "Network Mode" is LTE/CDMA.
