My voice is too quiet on the other end
• Make sure you position the microphone, which is below the keyboard,
close to your mouth. Make sure you are not covering the microphone
with your cheek or chin.
• Check the signal-strength icon. If the signal is weak, try to find an
area with better coverage (see Signal strength is weak).
I hear static or interference
Check the signal-strength icon. If the signal is weak, try to find an
area with better coverage (see Signal strength is weak).
If you're using a hands-free device enabled with Bluetooth
®
wireless
technology, try the following:
• Move your smartphone closer to the hands-free device. Audio quality
degrades as the distance between your smartphone and the hands-free
device increases. The effective range for a hands-free device varies
among manufacturers.
• Confirm that no obstructions, including your body, are between the
smartphone and your hands-free device. For example, move your
smartphone to the same side of your body as your hands-free device.
My smartphone seems to turn off by itself
Your smartphone 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).
If you restart your smartphone, wireless services, such as Wi-Fi and
Bluetooth, are automatically turned on if they were on before the restart.
However, if the smartphone can't determine if a wireless service was on
before the restart, that service does not automatically turn on (see Turn
your smartphone on/off).
My smartphone doesn't ring
• Make sure the ringer switch is turned on. If you can see the red next to
the switch, the ringer switch is turned off. Slide the ringer switch on.
• Check the ringtone volume. Open Sounds & Ringtones and drag
the Ringtone Volume slider to the right to increase the ringtone volume.
• If you are using a ringtone you installed, open Sounds & Ringtones
and tap Ringtone. Tap the default ringtone for your smartphone. If
selecting the default ringtone solves the problem, the ringtone you
installed is not working properly. Delete the ringtone you installed from
your smartphone by following the steps in Delete files and folders using
USB Drive mode.
My smartphone doesn't vibrate
• Make sure the ringer switch is turned on. If you can see the red next to
the switch, the ringer switch is turned off. Slide the ringer switch on.
(The ringer switch needs to be on to test vibrate mode.)
• Make sure the vibrate settings are turned on:
• Open Sounds & Ringtones .
• Under Ringer Switch Off, tap Rings & Alerts and then tap Vibrate.
• Under Ringer Switch On, tap Rings & Alerts and then tap Sound &
Vibrate.
• Tap, hold and drag the Ringtone Volume slider in either direction. The
smartphone should vibrate, and the ringtone should play.
