Point of view issue

Everytime I am placing a block and then when I am turning, my point of view is turning to the ground and then I am accidentally removing a block or I misplace a block. My little sister does have the same problem with an iPad 2, running iOS 8. I cannot take a screenshot because it is happening too fast. Now I have found that it is also when i am playing online (not in REALMS because I don't have one) and that it is not going down only, it is also going othersides.
