He samsung galaxy s5 has the fastest auto focus with 0.3 secs time and the MP COUNT is 16 MP u must be thinking that the sony xperia z2 has a 20.7 mp camera and the lumia 1020 has 41 mp but wait the lumia 1020 is not better than even the iphone 5s’s 8 mp camera the 20.7 MP camera of Z2 is great but has some issues like overheating and some audio video syncing issues especially lip syncing issues when u use that phone for video recording of 2k videos the phone overheats within 2 mins during 2k recording and u will need to shut it down the phone has 2 gb of ram which is not enough for a flagship . Yeah it will recieve latest updates but that too a bit late but its is simply not future proof as it is not having 4g lte and 3gb of RAM .
