v7.13.2

Minimum supported version: Android 7.0

What’s new

This update introduces Silent Alert Notifications for emergency messages, expands hardware accessory support, and includes bug fixes and stability improvements.

Feature updates

Silent Alert Notifications

Admins can now turn on Silent Alert Notifications, which mute the incoming emergency tone, the auto-played voice message, and the notification sound on receiving devices, while keeping vibration, the on-screen alert, and message history intact. This is the receiving-device counterpart to Silent Alert Activation (which silences the alert on the sender’s device). The setting is off by default and is configured from the Zello management console under Common → Emergency Alerts, either globally or per user template.
Emergency messages now trigger a new, more attention-grabbing vibration pattern on receiving devices. This vibration plays for all emergency receives — even when Silent Alert Notifications are turned off — and works even when the device is set to Do Not Disturb or Silent mode.

General improvements

Admins can now assign Ella, Zello’s AI assistant, to the multifunction key on supported USB-C accessories, giving users a hands-free way to reach her. In the console’s Multifunction Key Assignment setting, select AI Assistant.
Open Mic Detection now applies at the Standard level by default across networks, automatically ending unintended silent transmissions. Admins can change or turn off this behavior in the management console.
Added support for the Pepperl+Fuchs Smart-Ex 203, so its built-in PTT button now works while Zello is in the background or the screen is locked.
Added out-of-the-box support for the RAM Mounts USB Remote Speaker Mic.
App content now displays edge-to-edge on devices using 3-button navigation, matching the behavior already in place on devices using gesture navigation.

Bug fixes

Fixed a visual glitch where starting a recording in a channel with AI Message Summaries enabled could briefly reveal an extra history item at the bottom of the screen.
Fixed an issue where a sign-out notification could appear after an error occurred while adding an account.
Fixed a rare crash to improve overall app stability.

v7.12.1

Minimum supported version: Android 7.0

What’s new

This update introduces Silent Alert Activation for Emergency Alerts, along with improvements to the history screen, bug fixes, and stability improvements.

Feature updates

Silent Alert Activation

Admins can now enable a silent emergency alert, giving associates a discreet way to request help without drawing attention and letting Zello serve as a silent response button. When enabled, triggering an Emergency Alert produces no audible or haptic feedback on the sender’s device, while recipients are still alerted normally.

When an alert is triggered, countdown tones, transmission sounds, and vibration are removed on the sender’s device, though the on-screen countdown remains visible.
The setting is configured in the management console under Common → Emergency Alerts, where it can be applied globally or per user template, and is off by default.
For more detailed instructions on enabling this setting, see our support article. You can also see how Silent Alert Activation helps retailers meet New York’s silent response button requirement.

The floating date header on the history screen now behaves more smoothly and predictably while scrolling.

Three sensitivity levels available: Aggressive, Standard, and Relaxed
