Silent patent application

With the development of mobile phones, this button no longer needs to appear next to smart phones. Many Android phones think that this button is like chicken ribs for many users, so they don't add this button like Apple phones. The mute button on the side of the mobile phone was first invented by Palm, so the patent can be excluded. The reason why Apple started to set this physical key is mainly because before iOS7, the iPhone had no control center, and it was very troublesome to mute through software. For business people and office workers who often have meetings, it is usually necessary to set mute, so Apple must add physical buttons.

Another reason is that compared with the open source Android system, Apple's closed system does not have so many mute modes. However, android users can set mute in many ways, such as reversing the phone or customizing mute. This can be done, but the limitations of Apple's mobile phone are very strong. This is why Apple phones must have a specific mute button, while Android phones have no such consideration at all. That's why you don't need a mute button next to an Android phone.

But now Apple's mobile phone is gradually changing, and many iphone users have also said that Apple's buttons are inconvenient now. It is often accidental, so now Apple is also in the process of gradual progress and improvement. Most importantly, the buttons on Apple's mobile phone are not very useful for many people now.

Summarize; With the continuous development and improvement of the mobile phone system, Apple's ios and android learn from each other, and the system will become more and more similar in many functions. As far as the current or future mobile phone design is concerned, the setting of mute button actually increases the difficulty of making a thin, waterproof and scalding-proof full-screen mobile phone. So Apple may also delete the physical mute button on the iPhone soon.
