Pump up the Volume of your Vibrant Speaker
If you’re the kind of person that like to pump up the volume, there’s an easy way to make your Samsung Vibrant speaker louder.
XDA forum member bchalk has posted the steps required to make it easier to hear your speakerphone on your Android device.
You’ll have to punch in a code into your dialer and then select the volume type that you want to change and then set the volume level. The default level appears to be 88 but you can max this out at 100.
bchalk has posted a warning that ‘100 is very loud!’
