The Back Tap function of Apple phones has been loved by the majority of users since its launch. This function can set two shortcut startup methods on your phone. The way to use it is only necessary for the user to click on the back of the phone twice or three times to quickly wake up the pre-set program. Especially in the context of the current epidemic, many users have set this function as a quick start of the health code to facilitate in-and-out verification. According to foreign media reports, the Back Tap feature on Apple phones may appear in the Galaxy S and Flip series of , Samsung in the future.

In fact, as early as Google released Android 12 Pixel devices, it already had similar functions as Apple Back Tap, but Samsung did not add this function when designing its own UI system. Now, according to a report from Android Police, this feature has been added to Samsung's Galaxy series phones through a new tool called Good Lock. Perhaps soon, Samsung users will be able to unlock the feature through system updates.

In this function, users can use a module called RegiStar to customize the arrangement of the "Settings Menu" and gesture operations. Therefore, users can add shortcuts they are used to in this way. After the gesture is executed, it can start Google Assistant, assist in opening applications or changing settings, etc.
From the settings of this function and the mode of starting reaction, it can be seen that this is obviously different from the interaction of Apple phone Back Tap. In the Apple system, the click on the back of the phone is just one of the auxiliary functions, but in the Samsung settings it is a separate functional module. Since the running design of this function means adding more layers of abstract instructions, the RegiStar function is still in the testing stage.
