Zoom In-meeting controls are displayed as a black bar running along the bottom of your device's meeting screen. Keep in mind that these controls only display when you join a meeting. By default, mobile devices hide the controls unless you tap on the screen. To show them always, refer to the guide below. Tap the grid icon in the upper-right corner of the Zoom meeting screen to choose Speaker or Gallery.
By default, Zoom in-meeting controls are hidden on mobile devices such as a smartphone or tablet. You can activate the control bar and speaker grid by tapping on the screen but after a few moments, they will disappear. Follow the steps in the guide to always show the controls and grid!
By default, mobile devices only display the active speakers. But what about showing other attendees in the meeting. Follow the steps in this guide to display all attendees. The steps differ between a smartphone and tablet.
