Side Runner game actor is not keeping up

alitz09

I have been making a side runner game where the object is for the main actor to continue running at a constant speed and the player simply taps to make him jump. The problem that I am facing is that when the game starts the actor is not keeping up how he should. I have another actor that checks to see whether the main actor is falling behind or not and the main actor just falls behind and collides with the actor and the game ends. In the game salad creator the game works perfectly, it is just when I test it on android. The actor moves with a "move" behavior and has gravity to make him come back down when he jumps. Can someone please help me with this I would appreciate it so much.
