Minimizing Onscreen Information Make sure you do not include too much information at one
time on the screen of the idle browser. Because the idle browser has no scrolling capability,
excessive information cannot be viewed and slows down the performance of the phone and wastes
the bandwidth.
Limiting Page Content If a page contains too much information, use multiple pages to avoid a
delay in displaying information or scrolling on the page. Keep in mind that the phone’s memory
limitation hinders the amount of content that can be displayed on the screen.
Avoiding Interactive Features for Idle Browser Pages Make sure to create an application that
is informational only. Because the idle browser is not interactive, avoid including user input
elements like soft keys, buttons, or text input in your application.
Providing Clear Instructions Make sure to include clear instructions for the user. For example, if
the Select soft key is enabled on an idle page, there needs to be an indication like ‘Press Select’ on
the page. Do not assume the user will know to press the Select soft key.
Stabilizing the Refresh Rate Make sure your application does not require a frequent refresh of
the idle browser. You can control how often your pages automatically refresh using JavaScript. A
minimum 5 second delay is enforced by the phone.
Controlling the Refresh Cycle You need to control the refresh cycle using your application’s
response HTTP to the server. Configure the refresh cycle in the configuration file to be as long as
possible and only used as a recovery mechanism in case the HTTP connection fails due to a
network problem.
Providing Adequate Text Elements If a form contains text inputs and soft keys, provide a link
next to the text input so the cursor can be easily moved from the text box to display the designated
soft keys.
Limiting Cursor Navigations If a page includes multiple buttons or links, consider adding soft
keys as an additional input method for frequently used selections to avoid cursor navigations.
