ScreenRecorder

ScreenRecorder is an app that records everything on your screen into a video which you can share with others.
How would screen videos be important.

- assume you want to demonstrate something wrong with your phone to someone who is far, or vice-versa you would use screen videos.

-assume you want to teach someone who is far how to use particular feature on the phone maybe your old parents. you record a screen video and send to them

-Or maybe you would like to to show someone some things in your phone that would require you to use too many screenshots, a screen video would be your answer.

And remember the app records audio too so you can talk as you record your video, to better demonstrate something. Cool right? :-)

Note: do not record sensitive information such as passwords.
