MIUI 12 allows you to control your smartphone by touching the back panel
Earlier this year, it was revealed that Google is working on a feature called Columbus. It will allow users to touch the back of the smartphone to activate various functions. Apple then announced a similar feature in iOS 14 last month, but now it looks like Xiaomi is also joining the implementation of this technology.
XDA Developers user kacskrz discovered links to so-called Back Tap gestures in the latest beta builds of Xiaomi MIUI 12. He also managed to take screenshots of this feature in the MIUI settings menu. Unfortunately, he was unable to activate this feature on his Redmi Note 7.
Screenshots show that the feature uses double and triple touches. These gestures can be used to turn off the screen, turn on the flashlight, close apps, turn on split-screen mode, take screenshots, launch the camera, and activate the notification shade.
There is currently no information on Back Tap gestures on Xiaomi smartphones. It also remains to be seen if the feature will be limited to certain devices or if it will be available for all smartphones running MIUI 12.
However, it seems like a good alternative to Google's Active Edge sidebar compression feature and dedicated hardware keys.
