Fenix 5S Backlight Problem

Its only been 3 days since I got my 5S and I have problem from the second day, so frustrating.
My backlight only works by only pressing the light button. It doesn't turn on when I press the other buttons nor gesture. (In Settings both every option is ON both "during activity" and "not during activity') My screen is always dark unless I press the light button.
It used to work on day 1, but suddenly stopped working. What should I do?
