Gizchina News of the week
As of now, only the Redmi K30S Ultra of all Xiaomi smartphones supports the knuckle operation function. Even the double-priced Xiaomi Mi 10 Ultra does not support such a function. The reason why Xiaomi has been unable to follow up on the operation of the knuckles is probably due to the issue of patent authorization. There were rumors at the beginning of this year that Huawei had bought out the patent for taking screenshots of the knuckles. But with the release of the Redmi K30S Ultra, the rumors disappeared. The Redmi model is used as a preliminary test. If it can solve the patent problem and sensitivity problem. So the knuckle operation is worth extending to more models.
