Mine too. The Ulefone is better than that, to the point that I can use it reasonably easily with wet hands whilst paddling, but it's still unusable with proper rain (or sea spray) hitting the screen. The Armor8 has a 'smart button' on the side that you can assign various functions to, which can be used as the 'shutter' button to use the camera underwater. I have a 'proper' camera for that, so haven't got around to learning how to use it.
I bought the phone thinking I'd quite like to use it as a GPS, but it isn't really practical. Any time the screen is active and the display visible, drops randomly hitting the screen do random things. There's probably a way I could keep the screen locked but turn the display on and off with that 'smart' button, but I've not got around to properly trying to find a way yet. (I don't really need the phone for nav, it'd just be nice sometimes to see speed and course over the ground while paddling - in tidal waters they're often very different to the speed and direction you're travelling across the water.)
