The latest Android version, 4.0.4, was just released and already some users are reporting serious problems. It seems that the HSPA+ model of the Samsung Galaxy Nexus suffers from radio signal loss when the phone is idle, making owners lose calls.
Some of those who had the luck of receiving the latest Google update state that when the Galaxy Nexus is idle, it goes into standby mode, or whenever the processor doesn't coordinate enough activity, the smartphone loses its radio connection, preventing the user from receiving calls until the phone wakes up.
The issue may be caused by low CPU activity or even low power consumptions, with those that rooted their handset and modified the processor's clock speed to remain constant while idle, reporting no problems.
Of course, that is not the advised fix, as the battery consumption rate increases proportional with the CPU activity. Google officials are aware of the problem and are working on a patch as we speak.
The signal loss can be experienced only on the Galaxy Nexus, other devices that lack 4G support like the Nexus S and the Motorola XOOM, being safe for the moment.
Android 4.0.4 was released on April 3rd and comes as a minor update that improves screen rotation, which is now more fluid and faster, while accelerating the camera application for a smoother use. Also, multi-tasking animations are faster and more fluid than on previous versions.
