Samsung Galaxy S3 here is Official update I9300OXABLFB for improve the call quality

Great news for all owners of the Galaxy S3. The last official update  I9300OXABLFB  which introduced the notification bar light control, has also added a new feature during calls. As you can see from the images during a call, you can select the button " Extra Volume ", a real boost to the audio of the call that will allow you to hear the other party in a better and with more volume.

 

This option works with both the earpiece, and speakerphone mode and the improvement of audio power you feel well enough. There is obviously a double power compared to the maximum already good in the audio call, but the conversation will be heard best. Clicking the button will an equalization of the sound slightly different, with less bass, more treble and more volume.

For the user, this equates to a conversation heard best especially in noisy environments and particularly crowded. Also great for hands-free car.
