Because the screen of the mobile phone is damaged, how can the computer get the contact and SMS permission when connecting to the mobile phone?

You need to know that your mobile phone has turned on the USB debugging function when connecting to the computer, so that you can display the contents of your mobile phone on the computer. If the screen of the mobile phone is damaged, it can't be operated, so we can only change the screen. If your contacts and text messages are stored in your mobile phone card, that's fine. Just copy the content to another mobile phone.
