I have a blue Xbox bluetooth controller that works fine for me on mobile usually. However, after connecting my controller, I opened Terraria and even from the menu no inputs would register. I tried setting the control scheme to console and tried again, no cigar. I don't play Minecraft mobile anymore but I tested the controller on that to see if it worked, which it did just fine. I also just tested it on the android UI, and that was responsive enough. So, I don't know if the controller itself is at fault, but I do know Terraria isn't responding to any inputs. I should add that the xbox control help ribbons do show on the sides of the screen, so it's not like it can't detect the controller at all, just the inputs specifically.
