I have the 6s Plus and I'm trying to find a reason on upgrading to the i7 lol. The only thing I can think of is the advancements made in the camera system. I shoot DSLR mainly but thought this phone would be a nice addition. Then I thought....wait this phone is water proof. I can take photos or video under water! I went to check the specs on the Apple website and noticed there is no mention of water proofing at all. Would anybody trust it in the capacity I just described? Not even a mention about water resistance? Am I missing something?
