Apple’s iOS platform and Google’s Android operating system both lost usage share in November as BlackBerry and Symbian showed gains. Analytics firm Net Applications on Thursday published its operating system market share data for the month of November, and momentum has shifted quite a bit compared to October. IOS slid more than seven points to drop to a 54% share in November, and Android shed two points to fall to 17%. Android also slipped out of the No.2 spot it claimed from Java ME in October as the feature phone platform jumped seven points to a 20% share last month. RIM’s BlackBerry platform ticked up to 3% and Symbian usage gained a point and a half to hit 5%. Microsoft’s Windows Phone platform didn’t even register 1% on Net Applications’s radar. A graph outlining November’s smartphone and tablet platform market share by usage follows below.
