I have been using iPhone since 3GS, and I have tried other android phones as well. I currently like phones that have a touch home button(take s4 for example). Personally, it is a much better experience than using the physical button on iPhone, because it feels the button is more integrated with touchscreen experience. Well, just speaking of the home button. Iphone is still using the physical button. A lot of my friends use the touch assistance on iPhone to avoid physical home button, this might suggests people really need a touch home button on the iPhone. Right now, the 5s has a touch ID, this means the home button can actually sense your finger on it. Why does not apple expand this function more than just using TouchID to unlock or making a payment? I have thought some possible way to improve the usage of home button on 5s. 1.When you are using a app, simply press the finger on the home button for 2 seconds. And it will go back to the home screen just as we use the physical button. This requires no touch ID. 2.More over, if you press your finger again on the home screen, the phone will show the background app. Apple fans, please tell me what do you think of this. Do you prefer the old fashion way or you are on the same page with me.
