Many Sony Xperia users are reporting on a big bug that is affecting 2011 Xperia handsets that have been upgraded to the latest Android 4.0.4 Ice Cream Sandwich software update. The bug seems to affect LED notification, a crucial function for many people. Users are reporting that the notification LED does not flash when receiving SMS or emails when the screen is locked.
Strangely, the LED notification does seem to function correctly for missed calls. It will also work fine if receiving SMS/email whilst the screen display is on. A whole host of phones have been reported to have this problem including the Xperia arc S, Xperia pro, Xperia ray, Xperia neo V and others. There is a workaround to getting the SMS notification working again, but it involves installing the free SMSAwake application. Sony Mobile says it is aware of the problem and we imagine a bug fix will be on the way. Have you recently upgraded your Sony Xperia handset to Android 4.0.4? If so are you experiencing this problem?
