To unmute on phone Zoom, tap the microphone icon in the meeting controls during a call. If the button reads "Unmute," tap it to turn your microphone back on; if it reads "Mute," your mic is already active and tapping it will silence you instead.
How to unmute on phone Zoom: The primary method
The simplest way to unmute yourself in a Zoom meeting on your phone is through the on-screen meeting controls. While in a call, locate the microphone icon at the bottom of your screen. Tap it once. If the icon's label changes to "Unmute," your microphone is currently muted, tap it to speak. If the label shows "Mute," your microphone is already live, and tapping it would mute you. This method works identically on both Android and iOS devices using the Zoom mobile app. Zoom mobile app for Android or iOS: Global minimum version or higher is required.
When you cannot unmute yourself
If the meeting host has prevented participants from unmuting themselves, Zoom will not allow you to unmute. You will see a message indicating that you cannot unmute until the host permits it. If the host has muted participants from unmuting themselves, the app will not let you unmute. In this situation, use the "Raise Hand" feature to signal the host, or ask them directly via chat to enable self-unmuting. The host restriction applies regardless of whether you are on Android or iPhone.
Auto-mute when joining meetings
Zoom includes a "Mute my microphone" setting under its mobile app settings. When enabled, your microphone is automatically muted every time you join a meeting. However, you can still unmute yourself during the call if the host allows participants to unmute. To adjust this setting, open the Zoom app, go to Settings, and toggle the option on or off as needed. Mute and unmute sound (Android only): Audible only to you is a setting about device sound feedback, not microphone unmuting.
What doesn't work on phone
Phone volume buttons do not unmute your microphone in Zoom. The only button-based temporary unmute Zoom documents is pressing and holding the Space bar, which is a keyboard-only feature unavailable on mobile devices. Press and hold the Space bar is for keyboard push-to-talk, not phone hardware buttons. Similarly, the "volume, mute and speaker controls" on your phone's hardware do not affect Zoom's mute status, you must use the on-screen microphone icon to control your audio.
Frequently Asked Questions
Why is the Unmute button missing?
The Unmute button may be absent because the host has disabled participants' ability to unmute themselves. In that case, you cannot unmute until the host changes the meeting settings or manually unmutes you.
Does unmuting work the same on iPhone and Android?
Yes. Zoom documents the same mobile-app requirements and host restrictions for both Android and iOS. The on-screen microphone icon method is identical on both platforms.
What should I do if my microphone still isn't working after unmuting?
If you have tapped Unmute but others cannot hear you, check that Zoom has permission to access your microphone in your phone's system settings. Also verify that you are not connected to a Bluetooth device that might be using a different audio input.
Does Zoom document unmuting with phone volume buttons?
Not in the retrieved official support pages.
