Instead of using a third-party app, record your screen on Galaxy phones with Screen recorder. With Note10/Note10+, you can record almost anything that’s displayed on your screen! You can even use the front camera to record yourself during the video.
To open the Quick Settings panel, swipe down from the top of the screen with two fingers. Swipe left, and then tap Screen recorder. Once the countdown timer finishes, your phone will start recording whatever’s on the screen.
