Stability, compatibility listed as issues with Play and ICS
The official Sony blog published an update today, detailing the progress on Android 4.0 (Ice Cream Sandwich) upgrades on Xperia smartphones. As noted yesterday, the Xperia Play has been removed from the upgrade list. All other upgrades are proceeding as previously announced.
Sony's Ice Cream Sandwich upgrades began last month with the Xperia ray and neo V. The Xperia arc, neo, mini, mini pro, active, and Sony Ericsson Live with Walkman will all be upgraded starting next week. All upgrades will be version 4.0.4 of Android; Phones initially upgraded with 4.0.3—the Xperia arc S, ray, and neo V—will all see v4.0.4 during this process.
After extensive testing and customer feedback following a beta release of the Android 4.0 ROM for the Xperia Play, Sony has declined to upgrade the Xperia Play to Android 4.0. The Sony spokesperson said in the blog "Our priority has and always will be, to provide the best possible user experience on Xperia smartphones. In this instance the ICS upgrade would have compromised stability."
