Hopefully the above method will solve the problem for some of users.
But the problem i face is this:
Create new project -> 2 immovable physical objects and 2 movable physical objects.
On Galaxy note 3 there is only a little slow down (which is almost unnoticeable)
When the game layout loads on iPhone 4s for 3 seconds there is slow down (which is ok...), and after that 2 seconds of game freeze which looks very bad >.>.
-I used debugger and i noticed just after the freeze the physics engine cpu usage had a spike on one test 170+% and on another test 190+%, so somehow this must be related to physics engine?
