Android remains the dominant smartphone operating system, a status that is not expected to change although its share will decline somewhat as the market matures and competition solidifies. Samsung remains the world's top seller of Android-based smartphones, while the resurgence of LG and Sony have also contributed to its success in recent quarters. iOS will remain the clear number two operating system as the expected launch of a lower-cost iPhone will open up a wider addressable market. Windows Phone will solidify its position as the number three operating system with incremental share gains over the course of the forecast. BlackBerry operating system share will decline markedly over the forecast period due to tepid BlackBerry 10 reception and increased competition.
