Here are Android 4.4's Main Features
- Android 4.4 offers system-wide preferences for 'closed captioning'. Apps that offer video can access the user's captioning settings and adjust the display of the captions as per the user's preferences.
- Android 4.4 offers support for screen recording, and includes a screen recording utility that lets users capture video as they use the device and store it as an MP4 file. This also allows developers, reviewers and end-users to create walkthroughs and tutorials for apps, testing materials, and marketing videos, among others.
