Wrong display when change "Lock security" from "4-digit passcode" to "swipe"

[Yuan-Chen Cheng]

tested on
arale, r154, vivid-proposed and
n4, r155, vivid-proposed

Precondition
Lock security = 4-digit passcode

Steps
1) Enter "Security & Privacy -> Phone locking -> Lock security"
2) Select Swipe, and enter valid passcode, tap on "Unset"

Result
When it comes back to "Lock security" screen,
firstly item "Passphrased" is highlighted
after 1 sec, "Swipe" gets highlighted

Expect
"Passphrased" should not be highlighted anyway

Not sure if that's even a bug. The page is open with the current configuration selected, you open a dialog on top to change the option, the current config is still active, when you ack the change you can see the value change which confirms the action.

Matthew, what do you think?

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

Sebastien,

There are 3 options: A-"Swipe", B-"4-digit passcode", C-"Passphrased"

Current configration is B, new setting is A. The hightlight should move from B to A.
While C-"Passphrased" should not be highlighted anyway.

oh, right, I didn't notice it was going through selecting the invalid value...

[Sebastien Bacher (seb128)]

the selection is binded to the securityType, that must be changing in the backend temporarly...

when change phone locking from-digit passcode to swipe, the lock security still displays passcode. in fact, the screen lock change to swipe.but restart DUT. the lock security will displays as passcode.
