A lot of people say that the Samsung Epix’s ring volume is far too quiet — luckily Samsung lets us change this using a hidden volume control utility.
Please be careful when adjusting these setting. I suggest changing the volume level in small increments (1dB to 2dB at a time) and test your new volume settings out each time, this will prevent you from inadvertently maxing the volume out and either hurting your speaker/headphones/etc or even more importantly your ears! I haven’t checked out the max volume end of the spectrum so I don’t know how loud it gets, but I don’t recommend trying unless you incrementally reach the max volume and know that its not too loud.
When you find settings you like, post them in comments!
Used the WM9713 Control Util to access the Epix’s volume control panel:
- Launch the Phone app by pressing the green “phone” button on your Epix.
- Dial: *#0002*28346#
To change the Ring tone volume:
- Go to: Menu > Normal > Handset.
- Changed the DAC to: -10.5db (this may be slightly loud for some people, if so try bumping it down to -12dB)
To change the Handset/Speakphone/Earjack/Bluetooth (BTMono) volume:
- Go to: Menu > Talking > Select corresponding item
- TX: Controls how loud people hear you
- RX: Controls how loud you hear people

You can adjust the dB values to your preference.
Remember to select Menu > Apply after setting your dB values.
