Many people may have this problem. There are often illusions that the mobile phone is vibrating, but picking up the mobile phone and discovering it is not. This phenomenon is called “mobile phone vibrating deceptive sensory system.”
In fact, this phenomenon cannot even give you a definitive answer. The current consensus in the scientific community is that the illusion of mobile phone vibration is not entirely an illusion. It may be that the brain interprets the real physical signal as the vibration of the mobile phone, such as air blowing, muscle. Twitching, or our nerves are disturbed by electronic signals from the phone.
Surprisingly, people who mistakenly think that mobile phones are shaking are also people who are more enthusiastic about new knowledge. They like to absorb new knowledge through mobile phones, so they don’t really care about occasionally being fooled by false alarms.
