The quality of the mobile phone case in Huawei Mall is relatively reliable. As a well-known mobile phone brand, Huawei's mobile phone cases sold in its official mall have undergone strict quality control to ensure the durability and adaptability of the products. Huawei Mall's mobile phone case also provides a variety of styles and colors to meet the individual needs of different users. In addition, the after-sales service of Huawei Mall is more perfect, and any problems users have after purchasing can be solved in time. In contrast, although there are many mobile phone cases in JD.COM, the quality and adaptability are not as good as those in Huawei Mall. Therefore, considering comprehensively, the mobile phone case of Huawei Mall is better.
