Is Huawei's mobile phone maintenance and after-sales information safe and reliable?

Huawei's mobile phone maintenance process will involve users' private data, so Huawei strictly manages and protects the maintenance process. In Huawei's officially authorized maintenance center, maintenance engineers need to abide by strict confidentiality agreements, sign confidentiality agreements, and promise not to disclose any user data and information. Usually, only with the user's consent, the maintenance personnel will back up the data and reinstall the system. After the maintenance is completed, the user's data will be deleted in time. Therefore, Huawei's mobile phone maintenance after-sales information is generally safe and reliable. If you have any questions or concerns about this, you can consult the maintenance personnel about relevant policies and regulations during the maintenance process.
