N64oid & SNESoid A and B buttons issue!

I'm using a Samsung Galaxy Player Wi-Fi 5.0 . (The exact model is YP-G70) I'm facing a problem regarding the A and B buttons in N64oid. If I hit the A or B touch buttons, each of them acts like I'm hitting both at the same time. That being said, I can't move in games like Mario Kart 64 nor can I properly jump in SM64. (He would kick and jump up a short distance)

I got fed up and downloaded SNESoid, only to find the exact same problem. :P

Anyways, I'm hoping perhaps maybe yongzh or anyone who might be able to help me fix this problem would read this, as I've only found a very small number of people on the internet with the same problem, none of which have found a solution.

Thanks in advance!
