.....You'll notice that as you depress, the phone screen portion would slide up from the keyboard. When this happens, you will naturally try to support the phone not from the buttom, but from the end (screen side). The problem with this is that you will inadvertantly press something with the back of your thumb, from which the only way to exit out is to use your left hand. In other words while it is possible to take a pic with one hand only it really takes a lot of practice and it is cumbersome. Hope this explains my frustration.
