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
