How To Use TTY Mode On Samsung Galaxy S4

Learn how to use the TTY mode on your Samsung Galaxy S4. A TTY (also known as a TDD or Text Telephone) is a telecommunications device that allows people who are deaf, hard of hearing, or who have speech or language disabilities, to communicate by telephone.

Your phone is compatible with select TTY devices. Please check with the manufacturer of your TTY device to ensure that it is compatible with digital cell phones. Your phone and TTY device will connect via a special cable that plugs into your phones headset jack. If this cable was not provided with your TTY device, contact your TTY device manufacturer to purchase the connector cable.

• From the Home screen, tap Apps > Settings > My device tab > Call > TTY mode.
• Tap TTY Full, TTY HCO, or TTY VCO. A green checkmark will appear. Tap TTY Off to turn it off.
