DSLR Controller was the first and remains the best app to fully control your Canon EOS DSLR from your Android device, through USB cable or Wi-Fi connection. No computer or laptop required, no root required, only a compatible mobile device, a compatible camera, and if connecting through USB, the right cable. We strongly suggest you read up on the website (http://dslrcontroller.com/) about what DSLR Controller can do, how it works, and how to use it, before purchasing. The website contains a wealth of information you should know before using. Not all devices are compatible, especially if you want to use a USB connection. For a free app you can use to test compatibility, see the "Remote Release" app (http://market. android.com/details? id=eu. chainfire. remoterelease). If you need a refund, go to our website (http://dslrcontroller.com/) and follow the instructions in the FAQ entry. We cannot process refunds through email.
