I own Xperia Mini Pro which has Android 2.1-update1. I noticed Accessibility settings in my phones settings. What are these settings and why these settings are required ? I opened these Accessibility Settings. I can see an option "Accessibility" with a unchecked check box in disabled state. It always in disabled state. I don't know when it is going to be activated.
You need to install apps that are classified as "Accessibility Apps". The most used ones are part of the Eyes-Free suite (Talkback, Kickback, Soundback, Accessibility Preferences, Eyes-Free Shell, Talking Dialer, Rock Lock, Walky Talky, Intersection Explorer), plus several useful 3rd party apps such as IDEAL Web Reader, IDEAL Magnifier, and K9 Mail.
