What changes have occurred in device control after upgrading to HarmonyOS?
Information about device control changes when using the HarmonyOS version of the App.
Since the pure HarmonyOS version of the App is currently in the iterative optimization stage, some devices may temporarily use the basic version of the control interface, and some functions may be unavailable temporarily. We are stepping up the development of the full-featured version, so please be patient and wait for subsequent updates of the App. The subsequent versions will bring you a better control experience.
