Android 4.0 Ice Cream Sandwich appeared first on the scene last year with Samsung Galaxy Nexus, and since then very few devices have been released with ICS. Last week official Android 4.0.4 update was released for Nexus and since then some signal issues have been reported with the device.
A number of users of GSM version of the device have reported problems with their handsets after installing the new Android update. The handset loses its signal when it is left in standby mode for a couple of minutes. This means device becomes unable to receive the calls, messages, or secure 3G connections. This can only be corrected if users bring his device out of standby mode. Further testing also shows that the minimum clock speed of the processor is raised to 700 MHz.
Some of the users even downgraded their device again to the Android 4.0.2 version and have reported that the problem was solved as soon as the downgrading was complete. It is still not known what really is causing the problem, but it seems that not all the Nexus devices have been affected by the problem, as many users on XDA developer forum have reported no issues after the update.
So, it is expected that the problem is affecting certain batch of the handset. Google has been notified with the issue, so hopefully a new solution may appear quite soon.
