FNaF 3 & 4 Mobile ports bug

So I downloaded the old fnaf mobile ports from 2015, and the all installed perfectly but fnaf 3 and 4 are having this glitch where its not fitting the full screen resolution, would anyone possibly know how to fix this issue?

I downloaded the old mobile ports to experiment with them and I need to have this issue fixed, a few months ago they fit the screen perfectly but no it's just looking like this.

Please let me know if any of guys know how to fix this
