Xiaomi officially confirmed earlier this week that it would launch the Mi Mix 4 flagship on August 10. Since the announcement, the company has been consistent in the release of several teasers promoting the device. One of the latest teaser posters from the Chinese tech giant suggests the device will utilize the UWB technology. The poster bears the title “new technology, new understanding” and contains a silhouette of what we believe to be the Mix 4 pointed toward a TV.

The Ultra-wideband (UWB) is a radio-based communication technology for short-range use and fast and stable transmission of data. It is a more advanced version of Bluetooth as it can precisely locate smart devices up to centimeter-level. A couple of months back, it was first rumored that the Mix 4 will arrive with a UWB chip.

A second teaer shared today by the company further reaffirms the Mix 4 will come with an under display camera teachnology. The original Mi Mix took the industry by storm with its full-screen, notch-less design. In subsequent models, Xiaomi has experimented with different designs ranging from pop-up camera to slider camera design featured on the Mix 3.

The chip will be used by Mi Share, a peer-to-peer file transfer service found on devices from some popular Chinese smartphone brands. The usage might expand as more products utilizing the UWB tech are released just like the Apple and Samsung smart tags.

In a related news, a blogger has leaked what he says is the tempered glass of the Mix 4. The tempered glass sits alongside that of the Mi 11, showing the difference in screen design between the two models. It can be seen clearly from the picture that although the Mix 4 uses a curved screen design, the curvature on both the left and right sides is much smaller than that of the Mi 11. This will likely bring a better display effect. Also, the comparion shows the Mix 4 screen is shorter and narrower than the Mi 11 which is visually more beautiful.
