How to restore the factory settings of iPhone

Before restoring the factory settings, I suggest that users back up the important data of their old phones in advance.

Open the phone, and click * * Settings * *-> * * General * *-> * * restore * *-> * * erase all contents and settings * *.

Enter the lock screen password or Apple ID password when prompted

Wait for the device to erase the content. When you're done, restart your iPhone, phone just like you did when you bought it.

The factory settings need to be restored twice in order to make the equipment cleaner.

（After the factory settings are restored. Restore the factory settings again. Restore factory settings for a total of 2 times）
