Sometimes, updates aren't as sweet as they initially sound. Such is the case with Android 4.0.4, which recently rolled out
to owners of the GSM Galaxy Nexus
. According to an increasingly vocal swath of members at xda-developers
(and confirmed by a listing on Google's own Support page), there are mysterious signal issues now troubling the device. For many users, there's an inexplicable loss of signal -- a complete inability to make or receive calls and text messages -- after applying the v4.0.4 update, though it's beginning to look like Sleep is the issue. For some, preventing the phone from going to into a deep sleep mode has solved the dilemma, but it has also created a life where a nearby AC outlet is more of a necessity than usual.
