No, or Apple surely would have touted it as a "courageous major feature".
Water-resistant means if you drop it in a toilet you won't go running back to Apple crying and demanding a replacement.
There is NO evidence of any changes from past models. Let's shoot this down now. The demos on YouTube of the phone working underwater may last for hours, not minutes, but you won't be able to *do* anything with it, any more than before.You can interact with the S7 screen while under water or just with a moist finger? I had one and recall it getting all wonky when I tried to use it when it or my finger was wet.
Think about it, people attended the conference yesterday and have already tried out the phone - someone may have also tried the wet finger operation with a glass of water already and can answer this.Considering nobody has tested that and the phone is actually not out until next Friday - your guess is as good as ours. I wonder if anyone thinks before asking questions like this. Like, why do you think anyone here would know this on a brand new phone announced less than 24 hours ago.
