Mapping issue - A and B map on same button -DS4

[metroidslayer01]

So, I've been playing GCN games on my Galaxy S10 using bluetooth and Ds4 controller. No issues at all. I update the controls once and now when I hit "a," it also thinks I'm hitting "b" at the same time. And when I press "b," it presses "a" at the same time. I usually map "a" to x and "b" to o. Now games are unplayable! I've tried reinstalling the app, clearing all game settings, clearing all buttons and re-mapping them, tried only using the game settings for mapping. Nothing seems to fix it. The virtual pad works fine, it's only the controller. Any ideas??

This may seems basic but, is the controller low on battery? Maybe it needs to be charged for bit. I've seen controllers do funny things when low on battery.
