Status: RESOLVED DUPLICATE of bug 1196177

(Firefox OS Graveyard :: Gaia::System::Window Mgmt, defect)

Description

[KTucker [:KTucker][Inactive 3/4/2016]]

If the user taps the home button as soon as the camera app is launching and goes back to the app, they will notice a non functional camera app. 

Repro Steps:
1) Update a Aries to 20150924111215
2) Tap on the messages app.
3) Tap on the compose icon and then the attachment icon.
4) Tap on the camera option and immediately tap the home button on the device.
5) Tap on the messaging app again and observe.

Actual:
The user will be taken to a non functioning camera and will have to force close the app to regain functionality.

Expected:
The camera opens properly and is full functional.

This issue does not occur the same way on Flame 2.5  

The camera functions fine but the viewfinder is frozen.

This issue does not occur on Flame 2.2

The camera app functions properly after going home right as the app is launching.

This current bug is a little bit similar to Bug 1196177. 
The similarity is: while camera is launching, immediately/quickly tapping the Home button, then reopening camera view will cause black viewfinder or malfunction of camera.

The Bug 1208266 seems to be duplicated with Bug 1196177, because the two bug's first broken&last Working are the same build ID.

Comment 5

[KTucker [:KTucker][Inactive 3/4/2016]]

Saw 1196177 but looked like it only occurred with button mashing plus it was written over a month ago so this should be resolved. This happens when going home only once while the camera is launching. Plus, on bug 1196177, it says Flame 2.5 affected but I am seeing a functional camera on Flame 2.5 but the viewfinder is frozen. Adding qawanted to double check the window on both issues to confirm they are indeed the same. If they are the same, we will dupe out but this issue is serious and needs to be fixed asap.

Comment 6

[KTucker [:KTucker][Inactive 3/4/2016]]

I reproduce this issue on the last working build in Comment 4 so the window appears to be incorrect. Adding back regressionwindow-wanted.

Comment 7

[Pi Wei Cheng [:piwei] (inactive)]

I've confirmed that the window on comment 4 is correct. Note that the first broken behavior shows a working viewfinder, but none of the buttons on the bottom works (the 'X' button, the shutter button, and switch to video button), this behavior is a little different than current broken behavior, which shows a black viewfinder and nothing works.

Comment 8

[Augustin Trancart [:autra]]

While my commit is in the regression window, I don't think it is related (only touches callscreen). The only commit that touches camera is https://github.com/mozilla-b2g/gaia/commit/e66589d4f7626f2a84dff4c6568ee7fcdc6028fd. So NI aosmond: do you think this bug is a dup of https://bugzilla.mozilla.org/show_bug.cgi?id=1196177 or somehow related to this commit?

Comment 9

[Andrew Osmond [:aosmond] (he/him)]

Yes this is a duplicate; I did not when creating the patch that bug 1189105 introduced the regression, but it is the same problem.
