I think this statement is biased, because some Android phones actually have mute buttons, including the early one-plus-one phones. Many people think that the iPhone has a mute button, which is its patent, so many people can't use it, but it isn't.
The mute button was invented by Palm, from which we can see that the mute button is not a patent of iPhone. So it has no right to let other mobile phone manufacturers not use iPhone.
Why has the iPhone been kept?
The first aspect is that consumers are more accustomed to the design of this mute key. It does bring us some experiences, and it is a very convenient experience, so it does attract users to use it to a certain extent.
The second aspect is the unique performance of Apple mobile phone. Generally speaking, many Android phones don't use the mute button now, while Apple phones have been using this side mute button from before to now. To some extent, this is considering the needs of users, and it is also the unique advantage that Apple has.
The third aspect, some people think it is a tribute to Jobs, but I think this possibility is very small. Although Jobs has his own ideas, the mute button may not exist to commemorate Jobs. I think it's more about Apple's own unique characteristics and the real demand of consumers for these contents.
Would you prefer the mute button of Apple's mobile phone?
Many Android users haven't experienced the advantage of Apple's one-button mute, and think that they can mute through the volume button, so there is no such strong demand, and no manufacturer is willing to invest in design and development, but what I want to say is that Apple's mute button is really cool.
1. busy iterating
2. Many details are inhuman. The better Meizu, the more the hammer can't keep up with the rhythm (heap hardware).
3. Apple imitates paml.
Don't one plus series phones also have a one-button mute function?
