[System Settings] lock screen not honoring timeout setting from system-settings

Adding design to get feedback for what intended behavior is.

Also, if I set lock time to 10 minutes the phone should still blank the screen after a shorter time (30 seconds? or other default) but it seems to just dim the screen in this case.

I personally like the phone locking straight away when I press the power button.

Since iOS was mentioned, my Android phone has the immediate locking behaviour. In settings it has separate 'turn screen off after' and 'lock automatically X seconds after screen turns off' settings, but pressing the button always locks immediately. This is the same as the settings we have on desktop.

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

I just got my retail Bq finally and for the first time I'm using it from pure user perspective, and from perspective of "would I migrate from my Jolla".

The use case is that one needs to be able to turn off the screen / disable touch when operating some machinery / walking around and then quickly get to glance back on the task at hand, for example a web page or a map.

So the current is:

"Lock when idle" -> 1/2/3/4/5/10min/Never

I think what would be needed is renaming "Lock when idle" to "Turn screen off when idle" and adding a new option, so that the lock menu would have:

"Turn screen off when idle" -> 1/2/3/4/5/10min/Never
"Lock after screen off" -> Immediately / 1/2/3/4/5/10min/Never

The "Immediately" would be the default and would not change the behavior for existing users and people who want to keep the behavior.

@Laney: I think on mobile we need the feature to turn screen off (and disable touch events) by power button without always locking with the lock code while at it.

This proposal is enhanced by my newly filed bug #1446635, which allows a quick way to force the locking even if "Lock after screen off" is set by the user to not be Immediately.

"But if I press the power button before 10 minutes it should not lock the screen. This is how iphone works."

This is not true of iOS. If I set auto lock to 'never' and then press the power button then the phone does lock.

I agree with Iain "I personally like the phone locking straight away when I press the power button." There should be a quick and easy way to lock your screen, should you not wish to wait 10 minutes (or whatever has been set) and the power button is a good way to do this.

The Samsung Android device does allow a user to decide (in the settings) if they wish to instantly lock with the power button.

The screen does not dim at all on iOS if the lockout is set to never.

I think the current default is ok but there should be an option to allow not locking immediately.

On iOS like current Ubuntu it's hard to follow navigation instructions, quickly lock the _touchscreen_ from further touches with power button to do something else on the street, then press power button to glance again what was the direction or shop of interest. It, like Ubuntu currently, asks for constant typing of the passcode which gets tiresome when you're doing this kind of repetitive glancing of the phone while wanting to handle the phone care free when not looking at it.

Having it optional and enabling the bug #1446635 features would have best of all worlds: the option to not lock with code immediately, and the "quick and easy way to lock your screen" of comment #6 both for default users and those who have enabled the optional non-immediate locking.

Thirdly, the opening part of 1446635 makes my navigation example super fast by bypassing the lock screen to go straight to the example's navigation app, which would be even more efficient than it currently is on Jolla where one still needs to select the app from multitasking view - on Ubuntu, one does get to the latest app directly after typing the passcode / swiping.

Even if #1444635 would be seen as too advanced feature, the fact that one gets straight to the latest app on Ubuntu from lock screen would make Ubuntu on par with Jolla in efficiency if the immediate locking would be made optional, but then one would miss the possibility to quickly lock the phone when using the option. I just argue that the double pressing of power button features for flash-opening + phonelocking does not add cruft since people who don't use it wouldn't notice it.
