Monitoring the status and trackball lights

The status light (to the right of the earpiece) and the Trackball change colors, flash,
or glow briefly to inform you of the charging status of the phone and other important
information.
The status bar at the top of the touchscreen also provides information about the
phone, as described in "Monitoring your phone's status" on page 50 and "Managing
notifications" on page 52.
