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 both the cases, your phone is held near some object (like your ear or the wall of your pocket). In such cases, the proximity will generate a message to your phones processor telling it to switch off your screen. Android and IOS have an API for proximity sensor. So, you can also use it in your custom program. May be say a flash light that switches of if you put your phone in the pocket.
