Games hang on mobile phone?

I have a Huawei P7 and 80% of all games hang and lay on my phone. What can be there and what can be done about it? Example games lagging are Paper.io, Hole.io, Color Switch, Subway Surfers

Antivirus app I've already loaded and the mobile durchgescannnt, nothing was found. I also accelerated RAM

Your phone is just slow. Since you can "accelerate" the Ram as often as you want and also make software moderately what you want, it's just slow.

You'd have to get a new phone to make the games run much smoother.
