Why aren't the call records, pictures and text messages of Xiaomi's mobile phone recorded?

You must have inadvertently turned on the unique "visitor mode" of Xiaomi's mobile phone. Take a closer look. After the phone is unlocked, is there a sign of a small fence on the notification bar at the top of the screen? If so, congratulations, you have entered the "visitor mode". In this mode, you can't view call records, text messages, pictures, multimedia information and so on. Games and phones still work. This is to reveal personal privacy information when lending a mobile phone to others. The solution is also simple. Press and hold the phone power button for 3 seconds, and a menu will appear-silent mode-flight mode-guest mode-restart-shutdown. Click "Guest Mode", and then go back and see if the call records and so on are all out.
