Good compact mic wind filter for phones?

[MacMurphy]

The easiest option is to cut some foam and rest it over the mic, but it is a bit big and not well secured.

Anyone have a better DIY alternative?

Ideally something that can come off easily, but not so easily it falls off. I would consider a long term option if it is small enough. The two mics on my phone are on the top and the bottom, next to the charging port. I don't want the big fluffy things you can buy. 

I just realized I have earphone foam. Do you think it would ruin the camera if I used super glue to stick some on?

The sound quality from those mics is pretty poor, even on the newest phones. Have you considered something like the Shure MV 88? It comes with a foam windscreen that's pretty effective, even outdoors if the wind isn't too strong. The sound quality is far better than what you get with the internal mics, and you can adjust the stereo width.  I have the first generation of this mic and my only complaint is that it was designed for recording loud things (rock music at concerts, I think) so you really have to crank up the gain for quieter sources. But the thing works well and is not too expensive. Only works with iPhone, though, so if you're using Android you'd have to find something similar for Android.

Let me know if you're able to break the laws of physics and come up with a compact solution that'll do what you want.
