What game controller do you use with your Android?

[Dustbury]

I just recently bought the Moga Pro Power (bluetooth) and it's a nice controller. I like the feel of the buttons and joysticks and the support seems promising. I've tried it with ePSXe, however, and I find that there's a little bit of an input lag. Doesn't seem as much when using an SNES emulator, but the PSone emulator is more noticeable. I have a Galaxy S7 so I'm pretty sure there's nothing wrong with the hardware.

Has anyone tried wired controllers with their Android phone? I was curious if that eliminates the input lag or if there are any additional complications that I should be aware of when attempting a wired controller with Android.
