[deleted] I'm sorry and since it looks like it isn't do you want us to just not provide any other solution and say go away? The original post doesn't mention anything about being baked into the operating system but I'll go ahead and entertain your idea...
There are lots of things I would like baked right into this operating system, but they have other most likely better priorities in mind over mine or this one. More than likely, because there are already existing solutions that everyone else is comfortable using and work very well
All you would literally have to do is install those two apps, provide them the wrong password five times
"oops sorry I just recently changed it why don't you try this one"
And then they themselves will wipe the phone.
And I could be wrong but I believe you can even set the number of failed attempts to trigger early
I accidentally wiped my entire phone by throwing it in my bag and having it pocket dial. So to say that this isn't going to be usable, I find that hard to believe
