How to record screen video on Android 5.0 Lollipop (no root required)
This app allows you full-on video recording with no root req'd
The new SCR Screen Recorder 5+ app is still in its beta version, so there might be some incompatibilities with the very limited number of devices that are running on Lollipop, but we do expect the developer to update the app regularly, fixing known issues.The app arrives in two versions: the free one comes with severe limitations, as you can record up to 3 minutes on it at most, and the resulting video has a watermark.
All it takes to record your screen is to fire up the app, and press the record key (it will capture the entire screen of your device), and to stop the video recording, just lock the screen and wait up for 2 seconds.
