"Hi Owen, this is exactly the same problem I had (except I didn’t - and never will have the stamina to - bike for 8 hours straight, LOL). see my reply on Kevin’s post.
I’m happy to say that my home button had slowly recovered after more than a week of on-and-off touch-and-go and eventually became fully functional again. the point I wanted to bring here (apart from drying your phone) is you need to do the menu-shutdown trick to see if your home button is back to normal. it seems once the button is detected to have some issue it gets disabled until the phone is restarted in a certain way.
In summary, keep drying your phone, try the menu-shutdown trick every now and then and see if the home comes back. may not work for everyone but can always hope for the best. good luck."
"Probably damaged the u10 ic chip in the middle of the HB. These suckers are fragile!

Ive tried a few as a test, first batch failed but got better with practise and now successfully been replacing the chips. This is only for the feedback touch element, not the touch id!"
the finger print / touch id works, but you cannot push the button and minimize an app or go to the home screen.
we replaced the screens 3 times, different screens, we replaced the home button also… You would expect that the button would work and the touch ID won’t…. But after the button replace nothing works.."
