You are still able to use you phone while it's in the sleeve. I didn't have any problems with the touch screen.
You can put your phone in either way so that it's the direction you want it for either arm. There is even a little hidden spot you can slip a key into. The little holes line up with the headphone jack so you can listen to your music while your out for a run.
You can even slip it on over a long sleeve shirt for exercising in the cooler weather.
This arm band is good for more than just going out for a run. You can wear it any time you don't have pockets or if you need to keep your phone close. I highly recommend this product. I know I will be using it for a long time!
