Screen recording is a special option that allows you to record what happens on the display of your phone or computer. Until recently, capturing an image from the screen was almost impossible, as you had to have root rights on your phone. But Android 5 developers have corrected this misunderstanding, allowing users to record the actions occurring on the smartphone’s display without much trouble.
Xiaomi and Redmi phones running MIUI have a proprietary Screen Recorder app. There are also similar applications on Google Play. For example, you can use DU Recorder or Mobizen. In the settings of such applications, you can select the desired frame rate, set the contrast, turn off or on the microphone, and much more.
