Is there any way to record android screen in android 4.2.2 without rooting and PC? I want to record my android mobile's screen as a video. I tried many apps from play store but they didn't work with me. My device android version is jelly bean(4.2.2) and it is not rooted. So how can I record my screen without root?
Yes, you can.

Best App I have found for recording your phone screen: Shou. It requires rooted Android version 4.1 and up. Also, works without rooting your device.

Other applications that you can try Kamcord (Android 5.0+), etc.
