G29 random share or ps button presses while racing

[DFROST75 0]

My g29 wheel randomly while racing especially turning goes to share menu and or takes screen shots! As if I pressed the share button. It even some times goes right back to the ps4 main screen as if I pressed the ps button but i didnt! To get back to my race I then have to press X to back to the race menu then O to go back into race, ( at which point I usually lose control as I am mid corner. So frustrating  and game is almost unplayable. Does anyone have any ideas if its the game or wheel issue? Or any tips,on how to fix it
