1124867 - [Privacy Panel][Remote Privacy Protection] Lock screen improperly respects Screen Timeout settings following an RPP function

Status: RESOLVED INVALID

(Firefox OS Graveyard :: Gaia, defect)

Description

[Martin Shuman [:Marty]]

Attachment: logcat-RPP-Lockscreen-Timeout.txt

Description:
When the device locks itself following an RPP command, the screen will still respect the user setting in Display for the Screen Timeout.  This means that after the device is locked, it will take at least 1 minute for the screen to shut off, and may not shut off at all if the user set the Screen Timeout to 'never.'

Ordinarily, the device will turn the screen off after 10 seconds whenever it is at the lock screen, regardless of the Screen Timeout setting.

Note: This issue only occurs if the device was unlocked before the RPP function is received.  If the device was already locked, or if the user manually shuts off the screen with the Power Button, this issue will no longer occur.

Repro Steps:
1) Update a  device to BuildID: 20150122010203
2) Open Settings and navigate to Privacy Panel.
3) Progress past the Guided Tour, and select Remote Privacy Protection
4) Configure a Passphrase and enable the RPP Lock function
5) Navigate to Settings > Display and configure the Screen Timeout to be '2 Minutes'
6) From a second device, send 'RPP lock <PASSPHRASE>' in an SMS to the DUT
7) Observe the time it takes for the screen to shut off
  
Actual:
Screen shuts off after 2 minutes, improperly respecting the Display settings
  
Expected: 
Screen shuts off after 10 seconds, congruent with Lock Screen behavior under other circumstances.

NI on Component area owner for nomination and assignment.

Because the device was unlocked before the RPP function is received, I'm not sure the device should follow the behavior of settings in Display or 10 seconds in lock screen.
This needs UX's help to determine which one is the correct behavior.

I think the better way is to align the time all together, in case some people intent to set up time in specific second.
So I would suggest that no matter the phone is unlock or not, the screen timeout should be the same time as it display in settings app.

Closing this Bug as Juwei stated that this is a proper behaviour.
