Urgent! ! Hello, my Android phone now only has the function of making phone calls and sending text messages, but it can't enter the system settings and has no desktop.

What brand of mobile phone is it? This situation may be caused by deleting your own desktop. After the system is restored to the original factory settings, the starter is gone, and the settings naturally cannot be entered. I need to know the brand of your mobile phone and see if I can brush a new rom with the official brush tool. Or manually enter the engineering mode, download the required brush machine package and brush the machine again.
