If we take a stable phone than you are right. But at the moment
people need to start often and that leads to a situation where
these settings confuse a lot of people. It is even there if
you start your phone the first time. To raise user experience
this search should be delayed and it should be assured that this
search is happening on a very low priority so it does not block
anything. There could be even an indicator that is visually
announcing the search. But let us be realistic :)

Because there is always something in between black and white. There
could be some intelligent way to detect when it is necessary to
refresh. And users are quite used to know that software is stupid
and they praise the existence of a manual trigger for such actions.
