click back button goes to previous page and stop PAN gesture when rotate happening

I've released my app and it works fine but i've 3D model rotation code, pan. I'm using single finger for pan and 2 finger for rotate but if i use double finger for rotate and the model moving also. Need to control the moving action. I've 4pages, when i goes from 1 to 2 and 2 to 3 and 3 to 4th page then click the back button i need to come back 3 and 2 so on. Now it's not working. So, need to fix this issue also.
