F-Button Lite

Shop Google Play on the web. Purchase and enjoy instantly on your Android phone or tablet without the hassle of syncing.

This application lets you configure the blue F button of your HTC ChaCha. No root access required — simply install the application and choose what the button should do. It is possible to configure separate actions for short-click and long-press events.

This is a free application with a limited number of configurable actions. If you need more functions, such as starting arbitrary applications or controlling phone's media player, feel free to acquire the full version.

How to use:

Once you install the application, click the blue F button on your phone. The phone will ask you whether it should launch "Custom F-Button action" or "Facebook for HTC Sense" (see screenshots). Check the "Use by default for this action" option, and then click "Custom F-Button action". Now you can choose what should be done when you click the Facebook button. Repeat the same for the long press, and you are done.

Known issues:

- Most probably will not work on AT&T Status and HTC Salsa.

- Requires firmware version 1.23 or higher (check yours in Settings - About phone - Software information - Software number).

- Some applications (such as Gallery, Camera and Opera Mini) override the Facebook key internally, so it might not be possible to detect short clicks of the Facebook button in these applications. However, long press should always be detected correctly.

Use of permissions:

- Create Bluetooth connections, Bluetooth administration: to turn Bluetooth on/off.

- Change Wi-Fi state: to turn Wi-Fi on/off.

- Camera (Take pictures and videos): to turn on the camera's LED flash (Flashlight function).

- View network state, Change network connectivity: to toggle mobile data.

- Modify global system settings: to change screen brightness.
