How to find the remote pinhole camera in the hotel?

Mobile phone screening.

The specific way is to close the curtains and turn off the lights after entering the room, so that the room becomes a dark room. Then turn on the camera of the mobile phone, keep your eyes on the screen of the mobile phone at all times, and carefully scan the place where the camera may be installed in the room. If there is a light spot on the screen of the mobile phone, then this should be the location of the pinhole camera.
