So you can set how many times you are allowed to try to unlock the phone in the lock screen settings. But what happens if that limit is exceeded? Does the phone brick itself so you have to reset it (which would be bad since everyone would be able to brick it)? Or does it lock itself down for a certain time?

"If you exceed the number of tries for the Unlock code, as a security measure, your data becomes inaccessible. You will need to contact Care to have your device reset."

From the user guide.

So instead of accessing my data, anyone who gets hold of my phone can make my data inaccessible and force me to have the device reset? Wow. Seems more like a security hole than a security feature to me... :-/

You can set the tries limit to "Unlimited", so you will never face a lock down situation.

Anyone with physical access to your phone can also break it. Besides, if someone has your phone in their possession and they try to unlock it, chances are they don't plan on giving it back either way. This selfdestruct means they have no way to ever access your data if they can't get the code right before tries run out. Of course, this means making backups wouldn't be a bad idea (but that's something you should probably already be doing anyway regardless of your paranoia level).

If someone has my phone and tries to unlock it, maybe they are looking for a cue who the owner is. Or they are just curious. Or drunk and/or silly. Furthermore, I am pretty sure that there are ways to access the data without entering the PIN (even though I haven't tried that). I am okay with security-features like that as long as they are opt-in, but when opting-in, users should know that they will possibly destroy all their data when operating the phone being drunk next time ;-)

they are optional, and you can read about consequences in users guide. What else do you need? Big red letters across the screen? =) there's a great saying: RTFM!

The iPhone approach is better in my opinion - introducing a delay after n number of wrong tries. Since the data is encrypted and cannot be decrypted without the pin / key, there isnt any need to delete the data like the blackberry approach chosen by Jolla.

Hm. Excellent question, I was always wondering. Just try and tell us. Seriously: logically, this should trigger a login loop, which is supposed to be resolved through the recovery mode.
