In This Posting, I had reported to the readers, that Google Smart Lock was working for me, except for the fact that I had made a silly usage error. Well there is a component to Smart Lock, which updates itself from Google Play, and which states the Security Policy in greater detail, than the programming itself, that may not get any update until the user upgrades to a higher version of Android.
In fact, I would not rule out the possibility that this Security Policy could be personalized whenever it updates, which could lead some users to anxiety. In reality, if there is a policy update that prevents our device from just unlocking, this should be nothing to get anxious about.
It was never a part of the system, that if a Trust Condition is met – even fully – our phone is guaranteed to unlock by itself. Sometimes, even though the condition is met, mine does not unlock, once or twice. And when that happens, this has its reason for being, and may just be because Google thinks I need the extra protection.
After all, incorrectly unlocking once, can be much more devastating that incorrectly not unlocking, because in the latter case, the regular measures to unlock the phone still work. I am assuming the same holds true for the reader.
But just recently I noticed that my phone was not unlocking anymore when I was at home. It had done so before but then just stopped. There are a number of reasons why this can happen. For example, Google might replace our own definition of our home address – which looks like just a random address on their servers – with our official address. And then one thing which can go wrong, is that our official address might not be positioned exactly, where our GPS etc. places us. My phone often thinks it is located just outside my window, on the opposite side of my building, from where the street address is located…
Yet, there are certain errors which will not just go away, until they are specifically corrected by a human being. And so I went after this recent issue.
(Edit 07/13/2016 : ) I had tried to solve this problem, by accessing the fact that my phone is synced with two GMail identities, but that only one of them had a Home Address set. I set the Home Address of my second GMail, to be the same as the first.
What resulted, was that the automatic unlocking started to work again – for one day. Then, it stopped working again.
I can only interpret this in one way. Apparently, Google servers determine that my Home Address, an apartment building, is not secure. There could be other people who look – according to the GPS – as though in the same place as me, but may not be. Google took a full day to determine this a second time, for the second entry.
This strikes me as good software.
