1150258 - [Windows Management][Camera Lockscreen]The user is able to access the homescreen AND camera passcode lockscreen share activity at the same time

Status: RESOLVED WONTFIX

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

Description

[Derek Harris [:DerekH] - Dont need info. Last day 6/5/15]

Description:
When the user is typing in a passcode on the lockscreen and tries to access the camera while they are typing in the 4th digit of their passcode, the lockscreen camera will appear, but the user will also be on the homescreen. The camera share activity will be have as if it is still on the lockscreen, but the user is able to use the home button to access task manager, and return home.

Prerequisite: Have a passcode enabled (ex:1111)

Repro Steps:
1) Update a Flame to 20150401010204
2) Press the power button twice to enable the lockscreen
3) Swipe right and enter in the first 3 digits of the passcode set
4) Tap the camera icon, the quickly type the 4th passcode digit
5) Take a picture and view the preview
6) press and hold the home button


Actual:
The user is taken to the passcode camera share activity. When the home button is held, the task manager is accessed. If the user selects any app while in the task manager, the camera share activity will still be shown.


Expected:
The user is either brought to the homescreen, OR is brought to the passcode camera share activity. Not both.

This issue DOES occur on Flame 2.2, Flame 2.1, and Flame 2.0

The user is taken to the passcode camera share activity. When the home button is held, the task manager is accessed. If the user selects any app while in the task manager, the camera share activity will still be shown.

Greg, could you help here?

Comment 5

[Greg Weng [:snowmantw][:gweng][:λ]]

I think it's a missing racing from very old version, so you can reproduce it from 2.0 to 3.0. One possible solution is if user just tapped the secure camera icon, the pass code should be disabled until the camera got killed.. Or, if the pass code is pressed, the camera should be killed as soon as possible. But I don't know which one for you is more reasonable.

Maybe we need UX input here.

Comment 7

[Stephany Wilkes]

Seeing if Tif can take this. Tif, please reassign as necessary/appropriate.

Comment 8

[Tiffanie Shakespeare [:tif]]

The problem is stemming from the fact that once you type in that last 1 after tapping the camera icon, the phone actually becomes unlocked. Thus when you press and hold on the home button you're getting the task manager. (The bug applies to not only preview but also the camera)

If you were to type in 2 after tapping the camera icon (i.e. incorrect passcode), you see the incorrect passcode error just before seeing the camera viewfinder. Pressing and holding the home button does nothing because the phone is still locked.

As I see it, we have a few different options:
1. Remove the camera icon from the passcode screen
2. Prevent the user from tapping on the pin pad once the camera icon is tapped
3. Fix the task manager so that the correct app is opening
4. Have the camera behave the same as if the phone is completely locked - like swiping left on lockscreen (e.g. long press on home does nothing - the user must press home and enter their pin)

I will discuss with robmac tomorrow. Also NI'ing him here.

Comment 9

[Tiffanie Shakespeare [:tif]]

Hey guys - I discussed with Rob today and this is our preference...

Is it possible to fix the task manager so that it is launching the app instead of returning to camera or preview? (i.e. everything behaves normally as when the device is unlocked)

If this isn't possible - then we would want to disable the keypad so that if the user were to tap on the keypad after tapping the camera icon, nothing would happen (i.e. the full passcode could not be entered and therefore the phone would not get to the unlocked).

Let me know if there are further questions. Thanks!

For task manager NI Alive.

For the disabling I may submit a patch, but I would wait Alive's reply.

[(inactive after 6/18) Alive Kuo [:alive]]

I don't think we should fix anything in TaskManager because it seems wrong to unlock the phone and open SecureWindow(Camera) at the same time... TaskManager does not take SecureWindow into account, and SecureWindow won't close it when the phone is unlocked.

A(User can open SecureWindow and HomescreenWindow at the same time) -> B(SecureWindow is shown when task manager is opened), since A is already incorrect, why do need to fix it in B?

Comment 12

[Tiffanie Shakespeare [:tif]]

Sorry Alive, I'm not totally following what you're saying. But from the user's perspective this is a bug and the functionality seems broken. From their point of view, they don't know what "SecureWindow is (nor do I for that matter!) or when they are in it or what is should or shouldn't do. To the user, they know that pressing the home button shows the task manager and therefore it should work like its supposed to.

So the question is not whether we should fix it, but CAN we fix it. Can we use non-secure window instead? Or do something to avoid the issue you refer to you in your comment? Again, I don't totally understand what you're saying so it's hard for me to offer realistic suggestions :-/

But as I said in my comment 9, if fixing the task manager isn't possible or way too much effort then we should disable the keypad so the user isn't able to get into this situation.

Thanks Alive!

Let me clarity: my point is let's try to not open the camera on lockscreen and unlock at the same time. It's weird. The two operations are async so we cannot control. Is it a must-have feature to open the camera and go to homescreen at the same time? If not, let's do what Greg stated: don't open camera or don't unlock if camera button is clicked.
