After the device unlock code (not the SIM PIN) is entered one has to press on unlock. It would be nice when the device is unlocked as soon as the correct code is entered, without pressing on unlock.

Actually, that is a bad idea, since then you can guess the PIN without wasting tries, or you can lock your SIM by mistake by typing the wrong PIN as the Jolla submits it to the SIM every time you've typed four digits.

I don't mean the SIM PIN, I mean the phone PIN. Therefore I've updated the text to make it clear...

Although uncommon, the PIN might even be longer than four digits. As the OS can't know the length in advance, you would waste one unlock try for each digit after the fourth one.

Ah, you mean the code for device lock. Please add that term to your question, then it would be more clear.

Ok, device PIN. But same still does apply - either you have to apply a wrong guess when the correct length is reached or it would be possible to guess the code without any penalty.

In the first case, as user you might accidentally wipe your phone or in the latter case some one else will get to your data.

Standard behavior on iOS and WP. Therefore I really miss that. It's annoying to me if I have to press this small button 50 times a day. And I don't mind if the thief knows the lenght of my lock code. But I also understand that there is different opinions. So.. I might no longer be annoyed if it's a common swipe gesture. This 'll be much easier in my opinion and as a side effect it's going to match the UI concept finally.

Coming from a WP, I completely agree with you. It's annoying to type the "unlock" button so many times per day.

without "unlock"/"enter" button there is no way how to detect number of wrong attemps. so its compeletely WP feature, btw unlock button is just another button like number, so if you are bored by tapping last button, cutoff last number from your code :D i think that current way how to lock phone after time or force lock by double press lock button is perfect, and unlocking is simple as possible, as the different action is for single or doble press, nothing to chage here please

As currently lockcode lenght is not fixed, this feature request is not feasible on current architecture.

From my duplicate request..

I am aware that the proposed feature may lessen security, but this might be an user choice between a standard security code and an 'express' setting with fixed amount of 4 digits and no unlock button.

I don't see why it's not feasible. Yes, the number of digits will be revealed to the guesser, but that doesn't make a 5+ digit code easy to guess. Of course this should be optional, so that those who want stronger security can keep the current behaviour, but I think it's totally feasible and the length doesn't need to be fixed to 4 digits or anything else.

@ssahla: mostly its because of following scenario, your phone happens to open in your pocket, you have set 10 attemps limit, and your pocked generates 40 random characters. Bang, you phone is permanently locked and you need to send your device to care for reflashing. And we don't want people permanently locking their devices by accident (of course phone should never accidentally open in pocket as proximity sensors etc should work ok).

But yes in theory we are able to automaticly check the code when digits have been entered, so maybe we should consider adding option for that (just have to give warning dialog, that if you perm lock your device, its not covered by warranty).

@rainisto, thanks for your answer. I understand the pocket-lock danger, although if the proximity sensor works as it should, it's not a big risk. ”Highly unlikely” with automatic code check and ”extremely unlikely” with the current behaviour, maybe. :) But your answer says it's not feasible because the length is not fixed, and I don't see the logic in that.

I like it as it is now. But I think I see what the others try to say. Nothing to do with length of lock code. It should rather work like this: The phone already knows the lock code set. Once (and only in that case!) it is typed in correctly, the phone unlocks automatically. Not like: It "presses" enter after every digit typed. It would, though, require an 'on-the-fly' analyzis of the code (while being) entered, not post analysis as it is now (by literally sending the code to the device once entered). Just thinking out loud...

I guess a mentionable link is this one as it contains a comment from jolla stating that it won't happen:

I'm proposing to close this question then.
