EDITORIAL: This year, one of the TOP 5 camera phones came with a significant battery endurance improvement. The main camera retained the 1" sensor, lost the variable aperture but the 2 zoom cameras are now better then ever. There is no AF on the selfie and like last year, there is an extra camera grip available for the ultimate photo & video creation. Still missing are SD memory card and the desktop replacement feature. Promised are 4 years of OS updates.
