The specific location of the bookshelf for Huawei phones may vary according to different versions and models. However, in general, the bookshelf of a Huawei mobile phone referred to the storage device of a Huawei mobile phone that was used to store applications, games, photos, music, and other files. You can find the storage option in the settings of the Huawei phone and select the "Storage" option to see the available storage space. If the Huawei phone supports cloud storage, you can also find the required files or folder in the cloud storage. If the phone model is newer, you may need to search for the bookshelf app in the app store, which provides functions similar to an e-book reader to manage the files in the bookshelf.
