Last week Sony Mobile announced they were rolling out updates to their Experia S line of smartphones so users would be upgraded to Ice Cream Sandwich. Once the upgrade process started rolling out several people began reporting problems. Sony acknowledged these initial issues with the Android 4.0.4 ICS updates and commenced working to address them. They asked users to “stay calm” pending additional information.
On the Talk Sony forums, Sony now reports all updates will be “re-released.” Users can continue to check periodically to see whether their phone recognizes the new update as being available or wait for Sony to issue a new announcement regarding the re-released updates.
Although it is unfortunate that Sony is experiencing these problems rolling out the ICS update, it is good to see them keeping communication channels open and updating their users on progress towards a resolution.
