Home button suddenly stopped working

[simon wainwright]

I have had my Samsung galaxy s8+ for a week now everything was fine but yesterday the home button didn't work, when I was on a Web page I could press it and close them down, all off a sudden it's stopped working and when I press the bixby key it says bixby won't work it says CARNT USE BIXBY IN CAR MODE.
I have cleared the cache deleted the car play app looked on the Internet for a and and there are lots of people with the same problem.
Can anyone advise as it's driven me mad, also cleared cache on safe mode

If you've already tried clear cache partition and safe mode, then hate to say it, try factory reset. If that doesn't do anything it may be a hardware issue unfortunately.
