I get your point. I just assumed that in a world of billions of various hardware solutions, OS level sane software defaults would be reasonable to expect. Even if GPS sensors would not provide that kind of filtering. And since OS generally has a very good access to all the sensors... you get the rest.

They give good accelerometer readings. Also they give good GPS readings. All we need to do - "fuse" this.

Android has had a "fused location provider" which does this for a long time...

That's true, but we have drivers with phones without google play services. Strange thing, but it's true :) Also sometimes we need to use phone without internet access .
