How can I sleep at night and secretly play with my mobile phone without being found?

Turn the brightness to the minimum, turn on the eye protection mode, turn on the dark mode, turn the sound to the minimum, turn on the mute, lie on your side, and wrap the whole upper body in the quilt. If you want to change your posture, you must choose a safer one. Remember to put a pillow or something in front and hold it up with your mobile phone to avoid light leakage. If your parents leave home or walk around (listen carefully! ! ! ), be sure to put the phone back to its original location, and when you can play (just take it away), try not to make any noise (don't brush videos, listen to songs or something, but wear headphones! ! ), when you hear it, you should be prepared to be beaten. After you finish using your mobile phone, just turn the lights and sounds to normal, and then charge it (the risk of being found is relatively small, so I have tested it myself).

This is all my experience.
