I don't know why phone manufacturers can't figure this one out. Something thats as critical as the camera lens, NEEDS to be protected better. At least have it sit flush with the case back. They could make the phone slightly thicker, with a bigger battery. Galaxy S7 variants are all thicker than the 6 models... EVERYONE is raving about their higher capacity batteries. I have yet to read ONE complaint about the added thickness. The new S7 active does it right... hopefully others will get a clue.
Bunch of idiots designing these things. "Just because Apple does it..." (sarcastic tone)
