The launch of the Nokia Lumia 900 — the flagship Windows Phone — in April didn’t seem to give Microsoft much of a bump in smartphone share.
Microsoft’s share of the U.S. smartphone market remained at 4 percent for the three months ended in May, according to comScore.

The May figure is up slightly from the 3.9 percent of the U.S. smartphone market that Microsoft platforms (which include Windows Phone and the outdated Windows Mobile) held for the three months ended in February.
