The update and replacement of mobile phones is like the continuous evolution in the biological world. Because of the changing world, we must constantly adjust ourselves to adapt to this changing society, and it's the same with mobile phones. Technology is developing at a rapid pace, and the update and replacement of mobile phones is even more frequent. The retirement of a top-tier phone always leaves room for countless excellent products to fill its place. However, phones that step down from their throne are not losers; they are the inevitable result of technological development and also a witness to a period of history. Faced with these phones, we can only silently pray, hoping that they will not be quickly forgotten by everyone.
