272 Section 4A: Troubleshooting
My phone hangs up when I hold it to my ear
You may be accidentally pressing the onscreen button with your cheek. Try holding the
phone so that your face doesn’t press against the screen.
My phone seems to turn off by itself
Your phone has a power-saving feature that’s set to turn off the screen if it has been idle for
one minute. You can change the auto-shut off interval (see “Set the Interval for Turning the
Screen Off Automatically” on page 187).
If you restart your phone, any wireless services are automatically turned on if they were on
before the restart. However, if the phone can’t determine if a wireless service was on before
the restart, that service does not automatically turn on (see “Turn the Phone On/Off” on
page 20). If the problem persists and you’re using third-party applications, see “Third-party
Applications” on page 288 for additional suggestions.
Hands-free Devices
I can’t make or receive calls using a Bluetooth ® hands-free device
Verify all of the following:
ⅷ The Bluetooth feature is turned on (see “Turn the Bluetooth Feature On/Off” on page 249).
ⅷ Your Bluetooth hands-free device is charged and turned on
ⅷ You have already formed a partnership between your phone and your hands-free device,
and the hands-free device appears in the Devices list (see “Connect With a Paired
Device” on page 252).
ⅷ Your phone is within range of the hands-free device. (Bluetooth range is up to 30 feet (10
meters) in optimum environmental conditions, which include the absence of obstacles,
radio interference from nearby electronic equipment, and other factors.)
ⅷ You are away from other devices using the 2.4GHz radio frequency, such as cordless
phones and microwaves. (If this is impossible, move the phone closer to the hands-free
device.)
