I have been reading the rumors about the next iPhone. And we all know the Touch ID might in the back, but macrumors' readers don't it like why? Sincerely why? I have used Phones like that and it seems a good place for a fingerprint reader, your finger naturally rest in that place and you almost never notice when the device unlucks. But I want to know why you don't like it. Because of the design? Because we really want a finger print reader under the screen?
