Once started, SmartLight runs as a background application. It can be
accessed through the list of open applications (hold
down the Menu key). With SmartLight running, the backlight stays on as
long as the menu or an application window is in the foreground. The
backlight goes out as normal (i.e. after the period selected in Phone Settings) once
the user returns to the idle screen. The light also goes out as normal
after receiving or making a call, and after the phone displaying system
notifications (about new messages etc.).
For maximum effect, we recommend setting the backlight time-out period
(Phone Settings > Display > Light time-out) to the minimum of 5
seconds.
In order to prevent battery drain,
SmartLight will become inactive in case an application has been left
open for a long time. In this case, close all open apps until you see
the message "SmartLight has reactivated".
Tired of the display backlight suddenly dimming when you are looking
at the screen - e.g. while thinking about the right word for a text
message? Wouldn't it be nice if your phone knew when you needed the
light and when not? SmartLight does just that: Once you have opened an
application, the backlight stays on - until you close or hide the
application, switching the light off automatically.
