By default, the music stops playing on Android devices when you launch the camera app. This happens no matter what music app you use. The reason for this is convenience. For instance, you may want to record something urgently, such as your cat doing something funny, and may not have time to pause the music. In addition, you can add music to the video later using almost any video editing app. But with the rising popularity of TikTok and Instagram Reels, this feature may, conversely, be seen as inconvenient by some users.
