Here are some accessibility applications I wrote, available on the Android platform via the Google Play Store under the Productivity category. Please note that some of these applications are version or hardware specific, and may not be available for download for your device.
All these applications are free to download from the Google Play Store.
Description: Enables or disables WiFi and/or bluetooth while in airplane mode.
Also affects airplane mode triggering of WiFi and/or bluetooth. Particularly useful for disabling cell radio hardware while maintaining network connectivity.
Target: Android 2.1 and up
Description: Disables functionality of performing a long-press on the call button.
A hardware call button is available on older Android devices, as well as bluetooth headsets. Default Android behavior will result in launching of the voice dialer app or other applications assigned to this intent. This may vary depending on the manufacturer. As most newer devices are lacking the the call button, I have elected to make it unavailable past Android 2.3.7.
Target: Android 1.6 – 2.3.7
Description: Disables functionality of performing a long-press on the search button.
A hardware call button is available on older Android devices, as well as bluetooth headsets. Default Android behavior will result in launching of the voice search app. This may vary depending on the manufacturer.
Target: Android 1.6 and up
Description: Allows changing of Android system font size permanently.
Google has made this functionality available since Android 4.0, but not all manufacturers have made this available. Original Android sizes for reference: 85% (tiny), 100% (normal), 115% (large), and 130% (huge). This application actually adds a few more to pick from: 55%, 70%, and 145%. This application may result in some application layout issues. I personally recommend setting a size of 145% for users with poor eyesight. Some manufacturers have not made this feature available, or have customized Android in such a way that it does not take advantage of this setting. System menus, stock user interface elements are affected system-wide by this setting.
Target: Android 4.0 and up
Description: Disable widgets and/or camera access on the lockscreen.
Starting from Android 4.2, the lockscreen includes widgets and a camera interface from the lockscreen. Both of these features are accessible before disengaging the lockscreen. This application allows the user to disable one or both of these features. While this does reduce functionality of the lockscreen, it simplifies it and makes the device easier to use. (Formerly named Lockscreen Features Policy)
Target: Any Android 4.2 device
