Reviews for the Xiaomi Redmi K40

Redmi K40 Series Review: Would Be Affordable Flagship Phone of 2021
Source: Igeekphone English EN→zh-CN
Therefore, for the K40 series of the “full series of rising cups”, I think it can be regarded as an attempt by Redmi to develop upwards. Perhaps in the future, we can see that Redmi will have more “lifting cups” products and continue to consolidate and improve itself in the industry’s market and position. There is no doubt that the K40 series can and must make a good start for Redmi’s new 10-year road.

只有较少的手机有很大的屏幕。

大尺寸可以让屏幕有更高的分辨率。因而例如字体等的细节将会更丰富。不过另一方面,小屏幕的功耗会较低,而设备也会更轻盈小巧,售价更低。
