Comment 1

[ankit93040]

My observation : 

Card view was normal before this landed - https://bugzilla.mozilla.org/show_bug.cgi?id=1062136.

Sorry, I didn't check the behaviour on 2.1 or 2.2.

It is reproducible on Flame v2.0

Comment 2

[Sam Foster [:sfoster] (he/him)]

Can we confirm these STR for 2.0? I'll look at 2.1 and master but if QA is able to give any input on those branches that would help too.

Comment 3

[Aus Lacroix [:aus]]

Let's wait on QA to see if 2.1 exhibits the same behavior. Otherwise we're just trading one problem for another by backing out bug 1062136 if it is indeed the cause of this possible regression, it could also be a regression in getting the screenshot in gecko itself.

Comment 4

[Sam Foster [:sfoster] (he/him)]

In both master and 2.1 I dont get the dialer at all in cards vie: 
1. In Flame/2.1, open an app - I used browser and camera with the same result
2. Call the Flame/2.1
3. Accept call in Dialer
4. Long-press home button to get the task manager/card view

Expected: 
Dialer shows my active call as the first card and tapping on it returns me to the active call

Actual: 
App from step 1 is the first card. The dialer app is not shown (unless it was already open before step 1) The only way to get back to the call is to pull down the utility tray and click the 'call' entry there

Tested with Shallow Flash on 319mb using Engineering builds

This bug repro's on Flame KK builds: Flame 2.2 KK, Flame 2.1 KK, Flame 2.0 KK, Flame 2.0 Base

Actual Results: Bringing up card view when on a call recieved during another app active wil not show the Dialer as a running app.

If this repro's back to v2.0, I wonder if it is a bug at all. Can you confirm the expected behavior Francis or Rob?

I mean the issue described in comment #4.

[Francis Djabri [:djabber]]

Hi Sam, 

I would expect the behaviour to be as you describe in comment #4. Also, if the user taps on the dialer icon during a call, this should also return the user to the current call. 

However, I suspect that you're right and that neither of these things have historically been the case. The incoming call dialog has always been a strange view that isn't attached to an app. We used to have a big banner that let users switch back to the current call, and that papered over the cracks from a UX POV. But now that we don't, we should make it easier for users to switch back to a call. I'll let Carrie confirm what the behaviour should be since this is a Dialer issue.

Comment 9

[Carrie Wang [New account: [e-mail]]]

Hi, 

I agree on the expected results described in comment 4. I think it's another way to allow users get back to the call. And actually, we did open the dialer APP at that point. So it make sense the page appears in task manager. Thanks!

Comment 10

[Sam Foster [:sfoster] (he/him)]

I'm worried this bug confuses two potential issues. It seems like the callscreen not being in the task manager is a known, expected behavior that we want to fix for 2.2. I've opened bug 1098443 to track that. The original issue - card view is black for system message launched background app - I've just reproduced that on 2.0: 

STR: Flame/2.0
Decline incoming call
Long press on home button to bring up task manager

Expected: Either the dialer app doesn't show up at all, or it shows a screenshot of the dialer

Actual: The 'Dialer' card is completely black

Does *not* reproduce on 2.1

The same is true if you accept the call and then complete it. It doesn't seem to be timing sensitive - if you wait a few seconds after the call screen disappears before showing task manager, you still get the black screen.

Comment 11

[Sam Foster [:sfoster] (he/him)]

I'm removing affected flags for 2.1, 2.2, we are tracking that issue tested in comment #5 in bug 1098443

Comment 12

[Sam Foster [:sfoster] (he/him)]

sigh, clearing all these flag I set by accident. Sorry for the confusion folks.

[Tiffanie Shakespeare [:tif]]

Is this still an issue or can it be closed? Thanks!

Comment 14

[Shally Li（leave from Mozilla）]

Hi Tiffanie,

    This current bug doesn't occur on latest build of Flame KK 2.5&2.6 and Aries KK 2.5&2.6 by the STR in comment 0 or comment 10. 

Actual results: The app preview in card view shows normally, and isn't shown as black screen after ending the call.  
See attachment: Flame_v2.6.3gp
Reproduce rate: 0/10


Note:
Sometimes there is little problem that the black screen flashes for a second and then Dialer preview screen shows normally in card view after you quickly end the call.

cc :mcav so he's aware of the polish nit in Comment #14, but I think we can close this

Removing NI as Sam closed the bug in previous comment. Thanks Shally!
