PBK gestures not working.

Hi!
Got my Priv(stv100-4) yesterday,and after setting it up i realised that pbk gestures is not working.
It is enabled in settings,the phone has the latest updates and all blackberry apps are also updated. I also tried the "factory reset" several times.
Everything else is working perfect so i don,t see what causes this. Is there a setting somewhere that i am missing or did i just get a defective device?
If possible i would reflash the firmware,but haven,t found a way to do that.
Sombody have a good advise for me?
Was hoping to avoid sending it back for replacement...
