Currently there are millions of Android cell phone users. Whenever a user changes location, he/she should manually modify the sound mode (ring, vibrate, silent). So, it’s slightly inconvenient to constantly monitor whether the phone is in general or silent mode. Sometimes user might forget to switch the mobile mode and may create a disturbance in the classroom or in the work area. To overcome this problem “Sound Mode Application” is an Android application that allows a user to automatically change the sound mode depending on his/her GPS location. Additionally, the user may activate or deactivate the application whenever need be, and user can add as many locations as required based on their daily life.
