My wife got the Note 4 and took it back 2 days later. It dropped out WIFI when the signal got the least bit weak and switched back to data and wouldnt switch itself back. Google the reviews on it. She picked out an IPhone 6x and loves it.
side note, the reason she picked the Note to start with is cuz she had a Note2 and thought the 4 would be just as good.............. nope
