Back, start and search buttons on my lumia 925 are acting like i pressed them

Sorry for my bad English

When I'm using my L925 the back button actvates and the game closes, or the search button........ same with the start button. I got the phone since October 2014.
Can I do something about it or should I give it back (warranty is still valid).

Go to "touch" under settings and see if sensitivity is set to normal.
