Why don't the softkeys work Galaxy s6

A

AC Question

Hello,
I have a galaxy s6. For some reason neither soft key works anymore. They won't light up when I touch them or do what they are suppose to (go back/open folders).
I've restarted the phone, I've turned if off then back on, I've left it off for an hour then turned it back on, and still nothing.

Every other function works just find. I haven't dropped it or got it wet.

Please help.

Thank you,
Charlie
