(I already mentioned this, in here, a few days ago, in a comment - but,
because I know a lot of people who come here use Android devices and because
I think it's something important enough to create a topic of its own, to make
sure that everyone knows about this, here it goes the hyperlink, again...)
This should come as no surprise to everyone conscious enough of the
importance of using *only* Free Software. But, for the more naïve and those
less aware of the dangers of using proprietary one, this is a very good
example of what happens when you start adding proprietary software on top of
free one...
It, obviously, compromises the security of your whole systems and devices.
