I am very keen to know that how one can change a mobile phone into a remote listening device or spy-like device?? I want to make my mobile like this to use this technology to use like a prank on my friends. Please if anyone knows how to do it kindly give advice. Any advice will be welcomed for sure.

To turn your mobile into a remote listening device you should do the following preparations:

• You should charge your mobile totally and activate auto-answer feature
• Activate all the wireless plans
• Kindly check your audio options, if it is not silent then silent it
  
• Mute your microphone from volume settings
• Set all incoming ringtones whether it be message or call to silent
• You should deactivate the vibration

After doing all the preparations listed above you should test the device with your friends. Keep the experimented mobile in any room and inspect it from any other position with your friends situated in that room. You should call from any other phone number which your friends would not able to recognize. You should make noise to see how the sound will transfer through the recording mobile phone to your mobile phone. When you will call it will automatically answer the call and nobody will be unable to hear anything because all ringtones and vibrations will be deactivated. There is an added advantage that if you have covered your screen no one can see any light and no friend can hear you because the microphone is in mute condition but you can hear everything.
