    OK. This is simple enough that I can do it.

    How to use screen recording in Android 4.4 KitKat-screen-recording.jpg
    First, make sure your SDK Tools are up to date. Otherwise, this won't work.

    Plug in your phone, then open up a command line. You initiate the recording with a simple adb instruction, but it actually saves on the phone.

    The basic command you need is this:

    Code:
    adb shell screenrecord /sdcard/yourfilename.mp4
    You can name it whatever you want (within the usual limitations), and save it wherever you want on your device. (I'm lazy, so I've just been saving to /sdcard.)

    When you're done, just copy the file to a computer or wherever.

    Also note the arguments in the image above — particularly the one about bit rate. By default, it records at 4Mbps, which I've found to be inadequate, so I've been doubling that. So the command I've been using is:
    Code:
    adb shell screenrecord --bit-rate 8000000 /sdcard/yourfilename.mp4
    (And, yes. The help listing suggests setting the option in Mbps, but you actually have to do some math and use bps. Annoying, but not a huge deal.)

    To stop the recording, hit CTRL-C on your keyboard.

    Do you have an idea of what FPS it records at?

    And in case you're using Android Studio, there is a dedicated button to start the recording:

    This is a KitKat feature and not a Nexus 5 feature right? So I could use this on the Nexus 4 running a KitKat custom ROM

    Finally, after all these years. Shame it is restricted to >4.4 - for those after a solution for <4.4, have a look at the excellent but still in beta SCR Recorder: https://play.google.com/store/apps/d...der.free&hl=en

    So if you use android studio can you skip all the command line stuff?

    Hey, can't I use the command "screenrecord /sdcard/1.mp4" in the terminal emulator on the device itself? I tried but it says "Filesize = N/A" in ES File Explorer and the file can't be opened by any app.
