29.9% of Android’s 72% market share is "white box" manufacturers. A white box tablet is produced by a company (the manufacturer or ODM) that other companies (the vendors or OEMs) re-brand to make it appear as if they made them. These are a big threat to the well-known brands and are increasing being sold by retailers under their own made-up brand names. Many work very well and I have even used some as a basis for client, vertical single-use ‘kiosk’ style products. The down side is that the OS rarely, if ever, gets updated and for developers there’s usually a lack of Android adb drivers.
Strategy Analytics has new Q3 2014 research on World tablet shipments. Android reached an all-time high of 72% of the market while iOS declined 13% to 22.3% market share.
