4K is here! We're shooting video in 4K, uploading video in 4K and some of you are even viewing content in 4K. More and more phones are coming to market with support for 4K video capture as well, which brings us to our second 4K Battle, in which we pit two phones that can capture 4K content against one another and find out which phone is the better performer. This time around we have the Samsung Galaxy S5 and the Oppo Find 7a. Make sure to push that 4K button and enjoy the battle!
