iPhone 6s Camera Could Deliver Huge Upgrade
The Galaxy S6 Edge comes with excellent front-facing and rear cameras. The 16MP camera takes outstanding photos in great environments and good photos and video in noisey environments. The camera in the front is also great for selifies, much better than the iPhone 6's.
iOS 9 might not bring a complete overhaul to the iPhone's camera but the iPhone 6s' camera will almost certainly be able to compete with the Galaxy S6 Edge's. Rumors currently point to a 12MP camera sensor (with 4K support) in the rear and a 5MP camera in the front. Apple's jumped on the selfie train too, it seems.
