Cymbus Android App Release Notes

Cymbus Android App Release Notes


The Cymbus mobile apps for Android and iOS will automatically update according to standard app store rules.

Android 6.11.1 - February 2023

Dropping Android 8 Support

This app version drops Android 8 support; it does not install on Android 8 devices.

New Contacts and Call History buttons during a call

When you are in a call and want to place a second call or transfer the current call, it is now easier to access your Contacts and Call History. Note the new icons added to the bottom of the pop-up.

Change in handling concurrent calls

We made a small change with how Cymbus handles multiple calls so that Cymbus behaves in the same way as Native Dialer.

Previously when Cymbus has two ongoing calls and one of the calls ended, the remaining call automatically becomes unheld (or active in other words) so that the user starts hearing the call as soon as another call ended. Now, the remaining call stays on hold until the end user explicitly takes the call off hold.

Resolved known issue in Cymbus Android 6.10.2

Some users have reported that when a Galaxy watch is paired with a Samsung device running Android 13, they experience choppy audio with Cymbus. The solution to this issue is to apply an OS update on the Android 13 device.

Resolved issues

  • Corrected a VoiceOver prompt for the Select Outgoing Account button.

Android 6.10.2 - December 2022

Resolved issues

  • Fixed an issue on the in-call screen where the Contacts button beside the caller's display name did not appear even though the contact was saved in the local / native contacts list. This issue was observed for outgoing calls. Now the Contacts button appears on both incoming and outgoing calls as long as the contact exists in the native contacts list with the matching softphone number.

  • Fixed an issue where long-tapping on history record stopped Cymbus from working.

  • Fixed an issue on UI where the account status message did not appear when network was disabled on the device.

  • Multiple stability fixes.

Updates: Picture-in-picture on Android 13

With this app version, picture-in-picture is enabled again on Android 13 devices. Cymbus now shows the correct image when the device is in the portrait mode; however, you will not see picture-in-picture in landscape after navigating away from the call screen. Use a call head instead to go back to the Cymbus call screen.

Android 6.9.3 - October 2022

New Recordings page via the History tab

Cymbus now has a new page listing all the call recording files stored on your device. Previously in order to listen to a recording, you needed to scroll down the call history to find the entry. Some users found it hard or impossible to locate one if the call history has many entries.
