[Q] Android Games with ingame videos topic

Good afternoon all, I have bought a Cubot X6 which came with KitKat on it.

I have played a few games on it, Some games offer videos to watch to earn free gold or coins(Crime City & Angry Birds Go are the ones I have tried) every time I try to watch one of these videos the game crashes and restarts what am I doing wrong?

Regards

Paul
