为什么很少有安卓手机模仿iphone的静音键？
无论iPhone做什么，其他厂商都会跟风。自从iPhone用了金属机身，其他厂商也开始用金属机身。自从iPhone换上土豪金、基佬粉，其他厂商也开始用土豪金、基佬粉。自从iPhone回归玻璃，其他厂商也开始回归玻璃。自从iPhone用了刘海屏，其他厂商也开始用刘海屏。
大家注意到没有，这些被广大厂商全力跟进的都是非常明显的特性，比如机身材质、机身颜色、屏幕款式，因为这些特性都非常明显，消费者一眼就能看到。
但是呢，那些不太明显的特性，其他厂商就会有选择的跟进，比如取消3.5mm耳机孔（当然，这个用起来也确实麻烦）。
iPhone的静音键，就属于可以模仿也可以不模仿的特性，它不明显，不会对消费的刺激产生决定性作用。
那么，又是什么让厂商们决定不跟风做静音键呢？
我想，这大概是因为成本吧，软件上的静音比硬件上的静音成本要低很多，另外，静音键如果有的话，一定是高频次键。高频次就意味着容易坏（别说其他厂商了，iPhone的静音键就挺容易坏的），想要弄出经用的高质量静音键需要更高的成本。为了省这一笔成本，厂商们不跟着做也可以理解。
