The d-01J 取扱説明書 app, developed by Huawei Technologies Japan K.K., is a free utility and tool for Android devices. This app provides a convenient way to access the instruction manual for the d-01J device. Not only can users read the manual, but they can also directly launch various device settings from the description text, making it easier to use the d-01J.

It is important to note that this manual app is only available for the d-01J device and cannot be launched on other models. Before installing, users should also be aware that they may incur separate packet communication charges for downloading or updating the app, although downloading via Wi-Fi will not incur these charges.
