I’m DJing on equipment that’s connected via Wi-Fi to rekordbox for Android. Can I make/receive phone calls or use other applications on my mobile device at the same time?

If you make/receive a phone call or use another application while DJing using rekordbox for Android, rekordbox for Android will continue running in the background. However, applications running in the background may stop or pause depending on Android control. If this happens, you'll need to reconnect rekordbox for Android.
