Most smartphones support OTG technology, although many users are unaware of it.  The OTG allows you to connect any USB device to your smartphone, much like a computer.  The OTG has great potential, here are 10 ways to exploit it.

It sounds like witchcraft, but it's possible.  Just use a USB dongle to connect with your keyboard and mouse, then you can use your device as if it were a simple computer.  If you want to write a lot, this can save the day.

2. Sound card

For one reason or another, you may want to use a sound card other than the one that is integrated.  You can find a portable one, connect it to your smartphone with an OTG cable and then connect your audio equipment to the sound card gadget through the jack.

The touch screen is not always extremely accurate, and this can be a problem on some games.  If you are a gamer, you will be delighted to learn that you can connect a controller to your smartphone.  Many games on Android allow the use of a gamepad, I think especially GTA3 or Modern Combat.


4. Ethernet connection

If for some reason you have no wireless connection near you, maybe the only possible solution is to use the Ethernet cable that you usually plug into your computer.  Fortunately, you can use the OTG to use it on your smartphone.  You will need two devices: an OTG cable and a USB-Ethernet adapter.  You will then only have to connect it.
