Hello guys.
I had same issuse.
I had wet hands and pressed home button with wet hands in extensive period (1 hour) and home button stopped working.
I tried every advice in this thread.
- Left it 3 days, restart every day, home button still didn't worked
- Cleaned cache, factory reset, RUU restore, clean data fingerprint apk
- Getting home button wet again with water
Nothing helped.
My solution was next. Get
rubbing alcohol ( isopropyl ) containing 70% or more percentage of alcohol.
Soak only home button with it and left it untouched whole night with phone turned off. It will soak in and dissolve any water left and impurities such as oils from your thumb skin.
I turned on my phone in the morning and home button was working, and I got window asking me to set up fingerprint (it was missing before in settings).
To get better idea.
I put enough drops of alcohol to cover entire home button, but not to spill on charge port. Left it over night with phone turned off.
Rubbing alcohol is isopropyl alcohol, which is good solvent

Thanks all for advices in thread, and I hope someone will be able to fix home button as I did
