The Samsung Omnia i900 is one of the most widely used phones from Samsung's smartphone range. The Omnia i900 has advanced audio controls where the user can adjust volume and sound settings for both speaker and headphones. For this, one has to input a custom code following which the audio control appears. Using the menu option, a user can switch from Digital to Analog and also choose the decibels as well. In a similar fashion, the user can also change the settings for headphone volume as well. The user should, however, take care when choosing volume and sound settings in such a way that it does not cross the recommended capacity of the Omnia i900 phone.
