I have a Galaxy S7 Edge and got a USB input adapter so I could plug a controller into it to play Grand Theft Auto 3. Plugging an Xbox 360 Rock Candy wired controller into the phone worked fine, but when the triggers are pulled, the camera gets permanently stuck in a spin. I tried a DualShock 4 controller and the button mapping was all off, and the triggers had the same problem. Obviously GTA3 won't be getting an update any time soon to add built-in controller remapping. Vice City and San Andreas seem to have similar problems, based on what I've seen around the internet. Is there an app or some way to remap the controls for a controller so that they will work better with games that don't have built-in remapping?
