To use a PlayStation 3 controller with Android Nougat, you'll need an OTG cable that supports your device.
USB On-the-Go, commonly referred to as USB OTG or OTG, is a specification that allows some Android smartphones and tablets to act as USB hosts so that you can plug other USB peripherals (such as keyboards or flash drives) into them.
Connect your OTG cable to your phone or tablet.
Connect the appropriate USB charging cable to your PS3 controller.
Connect your USB charging cable to the female end of the OTG cable.
Once all the cables are correctly connected, a selection box will appear around an icon on your device. You can now use your controller to play games and navigate around your phone or tablet.
