The Redmi K40 Gaming will be powered by the Dimension 1200, when it launches next week. Despite being part of an already established lineup, it will essentially be a new handset with new cameras, a design and other hardware features.
One of them is shoulder keys for gaming, which will pop up from the side once a slider is removed. Here’s a neat video by Redmi, explaining how this works.
The brand says the keys are so good for clicking, they can even be used as fidget toys when the user is not gaming. They present a crisp sound each time they are pressed and closed with a magnet, providing much better feedback than current solutions.

According to the post on Weibo, the shoulders are extremely durable, and have been clicked 1.5 million times through no fault. Thanks to the close-ups in the video, we can also see that the frame will be metal, as well as the real shoulders, while the rear panel appears to be made of glass, which would enable charging wireless fast.
