Maybe Facebook (FB) is onto something after all with its notion that people want their smartphones to be centered more around its social networkFlurry Analytics released a new report on Wednesday showing that iOS and Android users spend roughly half their time either playing mobile games, which accounted for 32% of all time spent on both platforms, or using Facebook’s mobile app, which accounted for 18% of all time spent. The report, which used both Flurry’s own data as well as data from comScore and NetMarketShare, found that mobile users spend 80% of their time using some kind of mobile app on their devices and spend just 20% of their time using some kind of mobile browser.
