So this happened immediately after a couple of surf sessions. I've had no issues until I went surfing.
Now the back button doesn't work at all, and the light button only works for a quick click, it doesn't work when I hold it down to access the menu.
I've rinsed it with fresh water a few times, and then soaked it for 10 minutes last night. Then soaked it again for 20 minutes today. But it's still having issues, and really only seems to get worse each time I try something.
Its also doing this thing where it randomly vibrates just a little bit, like when you scroll the menu using the touching screen.
What can I do to sort this out?
