[krilin] Dialer-app surface freezes during outgoing calls

[Roman B]

My phone is a BQ Aquaris E4.5 Ubuntu Edition, running with Ubuntu 15.04 OTA 14 (stable channel).

The dialer app version installed is 0.1+15.04.20160825.2-0ubuntu1.

1. What I do
When I do an outgoing call.

2. What I expect
The surface of the app continues to work, I can hang up, put on the microphone etc.

3. What happens
The surface of the dialer-app freezes, the call goes on. But I cannot hang up, turn on the microphone etc.

The only workaround is:
- close dialer app in Task Manager
- Open other app.
- Re-open dialer app via the green bar on the top.
- Re-opened dialer app has working surface, so I can hang up, turn on the microphone etc.

The bug did already appear in OTA13 and is still present now in OTA 14.

The bug does not occure when I accept an incoming call.

The bus is reproducible.

Status changed to 'Confirmed' because the bug affects multiple users.

For MEIZU MX 4 it's the same. Bug is not fixed by OTA 14. Fixing a Dialer-Bug shoud be highest priority for a phone OS development.

For those experiencing this please provide any additional information you can as it is not reproducible.

How are you starting the dialer before the call? Does it matter if is started from the app scope, the launcher, contacts, etc?

Does it happen every time?

Does it help to clear the dialer's QML cache (in /home/phablet/.cache/QML)

Hi Pat.

I just made some tests:

Start dialer from launcher: 3 attempts outgoing call, dialer app freezes 3 times.

Start dialer from app scope: 3 attempts outgoing call, dialer app freezes 3 times.

Start call from contact app: 3 attempts outgoing call, dialer app freezes 3 times.

One remarkable thing: The freezed dialer app is different with every call. Sometimes I see the called number only, sometimes the number and the all the symbols above the red stop phone call button, sometimes only some symbols, e.g. the loud voice symbol, sometimes only the red button ... But every time the interface is freezed and the red button for stopping the call etc is not working.

Every time I can close the dialer app in the app task manager and then open it again touching the green bar on top during the call. Then the interface is working.

Then I tested some incoming calls. 3 attempts with incoming call, dialer app did not freeze a single time. All buttons for loud voice, stopping call etc are working. Every time the dialer app shows all symbols, the calling number etc.
