Huawei's mobile phone is restored to factory settings (SIM card and SD card are not inserted), and data formatting is selected without backup. Will text messages and address books still be there after turning on the phone? No, first of all, if the backed-up mobile phone information is local, it is backed up on the SD card itself, and the landlord has formatted it. It's definitely gone, and it's irreversible. The landlord should pay attention next time. If you want to format it completely, don't back it up in your mobile phone. It can be in the cloud or in your computer. In the cloud, you can download a Baidu cloud, or in the computer, you can download a computer version of the application treasure. This backup path can be specified by yourself. When you don't need it, just find the backup package and delete it, which is more convenient.
