Sony Mobile 在官方 Blog 發佈消息，Xperia S 將會在六月尾升級至 Android 4.0 Ice Cream Sandwich，緊隨其後是 Xperia P，而 Xperia U 就會在第三季升級。
而其他 2011 Xperia 手機，Xperia arc, Xperia neo, Xperia mini, Xperia mini pro, Xperia pro, Xperia active 和 Sony Ericsson Live with Walkman 亦會在下星期陸續升級 Android 4.0 Ice Cream Sandwich。
Xperia Play 不會升級
但另一方面，Sony Mobile 明確表示 Xperia Play 不會獲得 Android 4.0 Ice Cream Sandwich 升級。Sony 指經過多重的內部測試，發現 Xperia Play 若運行 Android 4.0 會表現得不穩定，尤其是遊戲方面。所以 Sony Mobile 決定不為 Xperia Play 提供升級。
In regards to Xperia PLAY, after extensive in house testing with our developer teams and working with our partners, we have concluded that a consistent and stable experience, particularly with gaming, cannot be guaranteed for this smartphone on Ice Cream Sandwich – therefore, we will not make the Android 4.0 upgrade available for Xperia PLAY.
This decision was also verified when we received similar feedback from the developer community; both experienced developers and advanced users, along with game content providers following our ICS beta ROM for unlocked Xperia PLAY smartphones.
