The screen-recording feature in Android 4.4 KitKat lets you record anything for 90 seconds that happens on your phone’s screen. It can be useful in many situations, for instance, if you want to show off features of an app, or playing of a game, etc. The possibilities are endless, if you have KitKat, but you need to connect your phone with your PC and access the ADB.
The app is easy to use. First, install the Android 4.4 Screen Record app from the Play store and open it once it has been installed, then choose video resolution, recording time, bitrate and countdown timer and tap “Record” button.
Anything that happens on your screen will be part of the video, including you using an app or even playing a game. Your recorded video will be saved in /sdcard/ScreenRecorder.
Please note that, this app requires root access to install. If you are interested, you can download the app free from Play Store.
