You can connect your GamePad to your LG as you connect  headphones or any wireless devices.

Your gamepad  supports android 3.2 and above.

METHOD 1: 


Install iPega Game Center English version(Google for that).  and install it. This will serve as  IPEGA remote Bluetooth gamepad driver for your Android device.
Enable Bluetooth on your LG phone.
Once you have installed the IPEGA Game Center successully you need to enable BitGames IME as default input.
Turn on the controller by pressing Y + Home button simultaneously. Wait until the red LED indicator blinks as it pairs with your device.
Once the red LED indicator blinks, open the IPEGA Game Center application. Go to mydevice and bind controller.
A console will open. This will help you calibrate your controller.  Try moving the joystick and the buttons.
Done. Test it with a supported game or an emulator.


METHOD 2:

If you have the PG-9028 model, you won't need  the IPEGA Bluetooth controller app.


Turn on your IPEGA PG-9028. Also, make sure that your LG Bluetooth is turned on.
Now, on your IPEGA Bluetooth controller,  press and hold both the X + HOME button, simultaneously.
Wait until you see the LED from your IPEGA gamepad with touchpad blinking constantly.
On your mobile device,  open the Bluetooth menu. Scroll down (if needed) and look for Available Devices. 
What you should look for is “PG-9028” or sometimes Android will see it as a keyboard input device.
Select PG-9028 to start pairing. Once the pairing is successful, you will notice that the LED light on your IPEGA PG-9028 will stop blinking.
Done.
