So im having this issue where when I connect a gamepad controller to my phone my screen (On Super Retro 16) turns from black into an off grey, and its SUPER annoying, I cant figure out why this is happening, if somebody has the same isssue or could lend me a hand and give me some ideas why this is happening, PLEASE dont hesitate to shoot me a MESSAGE or reply to this thread, I really need your help. Once again the screen (upon direction input) goes from deep natural black colors, to off gray. Thanks for reading, hope to hear from someone soon/. Please help
