Automatic unlock after correct device lockcode is entered

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

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...
