waterproof phone for Sat Nav?
I had originally started to look for a dedicated Satellite navigation unit, but have also started to research phones (despite never feeling the need to own a smart phone).
I now see a number of phones on the market that are waterproof. This would seem advantageous , by not having to have a separate enclosure. But what happens to a waterproof phone when it heavily rains? Does the rain not activate the touch screen and cause weird behavior? Is there an option to lock the touch screen when running the Sat Nav app, and still be able to see the map / get directions? I think an ideal system would involve being able to manually lock the screen when the sat nav app runs, and only unlock the screen again using some specific swipe. Does anything like this exist? Or am I just dreaming about something that does not exist?
