Japanese mobile operator NTT DoCoMo announced today that after careful consideration it will not be updating four Sony Xperia models to Android 4.0 Ice Cream Sandwich. The phones include the best-selling Xperia acro (SO-02C), Xperia arc (SO-01C), Xperia PLAY (SO-01D) and Xperia ray (SO-03C).
These models were under consideration for ICS but in the end NTT DoCoMo decided to shelve the update due to memory and performance issues. When questioned about why this may be the case, DoCoMo PR said that the 512MB of installed RAM was not sufficient for Android 4.0 and that 1GB RAM is preferred. This is quite a shame, especially since western users have been enjoying Android 4.0 ICS on these devices (apart from the Xperia PLAY).
