Dude, seriously? You signed up here for the sole purpose of making a post complaining about Google baking into the OS a feature that you previously had to use a paid third party app to employ?
And if you're going to complain, learn what you're talking about. Learn why apps like skiplock aren't working instead of saying baseless things about what Google has taken away from you.
Also, if this really mattered to you, you would have no problem figuring out how to use either bluetooth, NFC, or face unlock for your purposes. They are all extremely easy solutions. Not to mention there are other ways you can get around this if you really insist on using WiFi to unlock.
Perhaps you should take your own advice, and "learn what you're talking about" before attempting to belittle someone for their frustrations.
In previous versions of Android, including KitKat, you could ADD the feature (not natively in Android) of disabling your PIN when connected to your home Wi-Fi through the use of THIRD PARTY APPS (both paid and free).
Sure, it is physically possible to spoof your way past such a feature (and perhaps this is the reasoning behind Google's decision in Android 5.0 Lollipop to not offer Wi-Fi in their SmartLock feature). But it should ultimately be the user's choice if they want to risk themselves. Google could offer a notice, much like they currently do with other security features, advising of the risks of using Wi-Fi to disable your PIN.
That being said, both SkipLock and Tasker (with the Secure Settings plugin) are (as of yet) unable to do this feature now in Android 5.0. Logic dictates, then, that the code allowing this access to third party apps has been disabled, or at least rerouted, by Google.
And to say, "if this really mattered to you, you would have no problem figuring out how to use either bluetooth, NFC, or face unlock for your purposes" is completely irrelevant when you consider those options have nothing to do with using Wi-Fi to unlock your phone, a functions that has otherwise worked in the past.
"...there are other ways you can get around this if you really insist on using WiFi to unlock." Really? Please, do explain. That is after all the reason the this thread was created in the first place..... Or perhaps you are the one simply "saying baseless things"...
