Automatically watch screen shares
By default, someone's screen share does not play until you choose to watch it. To have shares start playing as soon as they begin instead, turn on this setting.
- Select your profile picture in the user tray.
- Select Settings.
- Select Audio and video.
- Under Video settings, turn on Automatically watch screen shares.
Adjust input volume

- Select Settings.
- Select Audio and video.
- Under Audio settings, adjust the Input volume slider.
The slider ranges from 0% to 100%. Higher values increase your microphone sensitivity.

Set your input mode
Input mode controls how your microphone activates during calls.
- Select your profile picture in the user tray.
- Select Settings.
- Select Audio and video.
- Under INPUT MODE, choose an option:
| Option | How it works |
|---|---|
| Voice activity | Your microphone activates automatically when you speak |
| Push to talk | Your microphone only activates while you hold a key |
Configure push to talk
When Push to talk is selected, two additional settings appear:
- Shortcut: The key or key combination that activates your microphone. Select Edit keybind and press your preferred key to assign it.
- Release delay: How long your microphone stays active after you release the key. The slider ranges from 1 to 2000 ms. A small delay prevents speech from being clipped at the end of sentences.
Adjust noise suppression
Noise suppression filters background noise from your microphone so others hear just your voice.
- Desktop
- Mobile
- Select your profile picture in the user tray.
- Select Settings.
- Select Audio and video.
- Under MICROPHONE CONFIGURATION, adjust the Noise suppression strength slider.
- Tap your profile picture in the bottom navigation bar.
- Tap Settings.
- Tap Audio settings.
- Turn Noise suppression on.
- Adjust the Strength slider.
Noise suppression is on by default. You can also adjust it during a call from the Audio settings sheet (tap the Settings icon in the call).
Higher values filter out more background noise but may affect voice clarity. Lower values preserve more natural sound but allow more ambient noise through.
Turn hardware echo cancellation on or off
On Android 10 and newer, Root can use your phone's own echo cancellation. It hears everything your phone plays, so it stops sound from other apps (like a video you are screen sharing) from echoing through your open mic to others. It is on by default.
- Tap your profile picture in the bottom navigation bar.
- Tap Settings.
- Tap Audio settings.
- Turn Hardware echo cancellation on or off.
- Restart Root for the change to take effect.
On some phones it works less well. If you have problems with your audio in calls, try turning it off. This setting does not appear on iPhone or on older Android phones.
Adjust individual user volume
During a voice call, you can adjust the volume of individual participants without affecting your global audio settings.
- Desktop
- Mobile
- Right-click on a user in the voice call.
- In the context menu, adjust the User volume slider to control their voice volume.
- Press and hold a participant's tile in the call.
- Adjust the User volume slider to control their voice volume.
The slider ranges from 0% to 200%, allowing you to boost quieter users or reduce louder ones. Your volume preferences for each user are saved and applied automatically in future calls.
Adjust screen share audio volume
When someone is sharing their screen with audio, you can adjust the volume of their screen share separately from their voice.
- Desktop
- Mobile
- Right-click on a user who is screen sharing in the voice call.
- In the context menu, adjust the Stream volume slider to control their screen share audio.
The slider ranges from 0% to 100%.
- Press and hold the participant's tile, or the tile showing their screen share.
- Adjust the Stream volume slider to control their screen share audio.
The slider ranges from 0% to 200%.
Your volume preferences are saved and applied automatically in future calls.
