Zulu UC

When the app closes, inbound calls are no longer possible to receive. Turning off all battery saving features does help keep the app running in the background for a little while, but once the app process stops running inbound calls are no longer possible. If this issue were to be fixed, I'd give this 5 stars.

This app is completely useless on the S10. If I dial a phone number I don't hear anything until someone picks up on the other end, no ringing, and if it goes to voicemail it's hit or miss if that will come through. Incoming calls rarely work. The app doesn't persist in the background, so you have to always make sure it's open and running. Integration with the primary phone app seems flawed. Overall disappointed considering I have a premium android device.

Chat and call logs are never up to date or on file. Yet, they only appear in notifications. Why? Stupid Java! --- New problem, and worst ever: Zulu is not letting any notification, any media, any ringtone, anything make any noise, at all; not even while set at full volume. --- Formerly: You are not letting us select Zulu as a secondary phone application under the kernel. Very disturbing. Additionally, Java runtime is crashing Zulu from calling any extension, at all.
