WARNING: 911 Emergency Calling Sprint recommends that TTY users make emergency calls by
other means, including Telecommunications Relay Services (TRS), analog cellular, and landline
communications. Wireless TTY calls to 911 may be corrupted when received by public safety
answering points (PSAPs), rendering some communications unintelligible. The problem
encountered appears related to software used by PSAPs. This matter has been brought to the
attention of the FCC, and the wireless industry and the PSAP community are currently working to
resolve this.
Proximity Sensor
You can access the LG optimus G™ proximity sensor through the Call Settings menu.
When receiving and making calls, this sensor automatically turns the backlight off and locks the
touch keypad by sensing when the phone is near your ear. This extends battery life and prevents the
touch keypad from activating unintentionally during calls.
To enable the Proximity Sensor:
1. Tap > > System settings > Call.
2. Tap Proximity Sensor to enable it. (A blue checkmark will appear.)
Noise Reduction
You can set the phone to reduce the background noise while using a hands-free call.
