One of Apple’s great features: both the old and new iPhones support it, and many people don’t know it yet

Many people may not notice that Apple has quietly added a physical button function to the iPhone after the release of IOS 14, but this function may not be found by most people. Of course, this is not to say that Apple has done something about the design of the iPhone, but through IOS 14, Apple has added “back tap” function to all phones that support this system. < / P > < p > this function is also very simple, as long as your iPhone is installed with IOS 14, and then turn on the back tap option in the auxiliary function. Then when you double-click on the back of the iPhone, you can trigger specific features on the iPhone. In fact, it’s just a feature added to the iPhone’s software upgrade, but Apple hasn’t made any special changes in hardware, but this feature clearly blurs the line between hardware and software. < / P > < p > there are also two function schemes of back tap, which are double-click on the back and triple click on the back. In back tap, users can set double-click and triple click function settings according to their needs. This includes but is not limited to: return to the main interface, information screen, mute, switch applications, open notification center or control center, etc. Moreover, users can set double-click and three-click as the shortcut of software startup. < p > < p > Apple’s goal is to provide users with more features to interact with the iPhone. With the function of back tap, many of our daily operations will become simpler, because no matter double-click or triple click, we can directly map to the app, or some functions that require us to perform multiple step-by-step operations. Now, as long as it is preset in the settings, it will be more efficient than in the past. This can be done with things like screenshots, browsing the web, or launching Siri. < / P > < p > of course, some solutions can be implemented by back tap, but it may not be easy to use in traditional ways. For example, to start Siri, we only need voice and browse the web I think it’s easier to use the touch screen than to click on the back of the phone continuously! < / P > < p > but the significance of this feature is remarkable, which means that users can effectively use the back of the iPhone to perform almost any operation imaginable. What’s more interesting is that although this function needs physical operation, it can’t be seen by naked eyes without physical buttons. Moreover, before using this function, the back of iPhone has no other meaning. It really realizes an application scheme that exists when users need it and disappears when users don’t need it. < / P > < p > and most importantly, this approach can be mapped to almost all the existing iPhone applications. If there are any new features to be added to the iPhone in the future, back tap can also be operated effectively without too much effort on the physical design side of apple. So back tap seems to be relatively simple to implement, but in fact, it requires apple to have great foresight in hardware design and highly cooperate with it in software system. < / P > < p > of course, for ordinary users, it seems more intuitive to use physical buttons to realize many functions on mobile phones, such as calling out voice assistant, such as screenshots, etc., but physical keys are always limited, and only a few functions can be realized. The functions of back tap can be said to be unlimited. We only need to set them in advance, which can create unlimited possibilities for Apple phones. < / P > < p > it is no exaggeration to say that the concept of apple is across the times. After all, no mobile phone can do such a thing. It seems very simple and easy to implement. But why didn’t Google and other mobile phone manufacturers think of it before? Now it seems that physical buttons are still the best way to achieve some functions, but the iPhone’s back tap function is definitely a powerful tool to expand mobile phone applications and functions. < / P > < p > the last thing to say is that there is no model limit for this function. As long as the mobile phone with IOS 14 system can be installed, it can be implemented. Users of both old and new iPhones can try this feature on their own after upgrading to IOS 14. In addition, even if there is a mobile phone cover is not a problem, as long as the case is too thick on the line. Now it seems that Google’s Android system is also developing similar functions. In the future, we may see more mobile phones directly copy apple! Huawei mate40 concept machine exposed, Kirin 1020 + curved surface full-scale screen, beauty hanging on iPhone 12
