Another indication of a bugged cell phone is reduced battery performance. If a mobile phone is tapped it is recording your activities and transmitting them to a third party. This leaves a footprint in the form of increased battery usage and as a result the battery loses life faster.
In a phone, proximity sensor is used to turn off the touch screen, while making a call with phone positioned close to the ear. You can test this by making a call and placing hand/object close to the speaker at the top, screen will turn off. This is done to avoid accidental touch while making a call.
