Tablet's original overlay gamepad

Hi there. My father just gifted me a tablet samsung SM-T560. Naturally, I’m playing in it now, and Retroarch rocks!!! There’s only one, not a problem, but a detail. As soon as I started the emulator in the tablet, it appeared with a magnificent kick-ass psx gamepad overlay. I changed it to test if my old custom retropad still worked in the tablet, but after that, I couldn’t find the magnificent gamepad that came by default. It was one with the keyboard button in the upper right, and R1 and L1 not in the corners of the screen, but in the centered right and left, respectively. I tried virtually every pad of Retroarch, but I can’t seem to find it. What’s the name of this pad, and how can I find it?

It should be one of the ‘flat’ gamepads, probably retropad.

Found it exactly there! Thanks a lot hunterk!!!
