Android and iOS are the OSs that app developers should focus on since they have captured over 85% of the smartphone OS market. Why should an app developer spend time on anything else since any other OS is in the shrinking minority?
Amazingly, Android holds 68% of that 85% OS market share and that is largely due to Samsung, the Korean company that manufactures over 44% of the Android phones sold. This amount out distances its next seven competitors combined.
Despite Microsoft’s attempt to break into the mobile phone market as of Q2 2012 it only accounts for 3.5% of the total market share.
