Some anecdotal evidence re: phone survivability in water...
So, my Find 7 is currently ~3 weeks old. I was at Wet Republic yesterday (Vegas) getting sloshed with the fiance and some buddies when I decided to be cool and dunk my phone in about 12 inches of salty pool water "just to see what would happen". It was in there for a good 10 seconds, but only realizing the risk of what I'd just done AFTER I pulled the phone out, my heart sank.
"Did I just ruin my device in a moment of stupidity?"
Immediately, I grabbed anything dry within arm's reach that would suffice to soak up water - towels, people, hair.
Screen check: still on.
Response to touch: ok.
I shut it off and disassembled the pieces to dry it further. After reassembling and attempting to power it back on, the phone went through a lengthy vibrating loop cycle that had me worried. The OPPO logo hung there without doing anything else. I put it in my pocket hoping it would fix itself. Thankfully, after checking on it 10 minutes later, everything was on and apparently in full working order. A visual inspection revealed moisture locked inside the front-facing camera. I told myself that, worst case scenario, if all that is wrong with my phone after this ordeal is a little bit of moisture locked in there, I will sing praises of this device forever.
Fast forward to this AM - before going to bed, I disassembled everything again and laid out the pieces on the night stand of our a-little-too-air-conditioned hotel room. Woke up, inspected the pieces, and VOILA - front camera was as dry as the heat outside. No rice bagging or blow drying needed.
Take better care of your toys.
TLDR: phone survived an intentional 10 second drowning in 12 inches of nasty public pool water. Front camera retained some moisture that dissipated after being taken apart and allowed to sit at the bedside overnight. Don't be me. Find 7 is awesome
