Hey people, I ordered the unlocked Galaxy Nexus from Google Play and got it delivered last week. I migrated to the $30 a month-unlimited text/data-100 mins plan from T-mobile (which I think is an awesome plan). After about 2 days into the plan, my phone lost complete signal connectivity. Repeated calls to Samsung did not help (T-mobile was good as the sim card had full reception on another phone), even a hard reset did not bring the signal back on. Finally I called the support number on Google and they offered to get the phone replaced. So I have the new phone now, and I have some questions about this whole issue. ICS 4.0.4 - There is a pending ICS update on my new phone, which I have not yet installed. I read on many forums that the ICS 4.0.4 could be causing the signal issues. So should I go ahead and install the update? I had installed the update on my earlier handset and faced the loss of signal. So not sure if I should. If it helps, my Build number is IMM30D, Kernel version is 3.0.8-g21f62a0 android-build@apa28 #1. Future updates - Are there any future updates to the ICS expected? If so, would they be addressing the connectivity issues? Color of the signal - I noticed that the signal indicator on my phone switches to gray from blue, during which I am unable to use data effectively. What does the change in color actually mean? I am quite new to the Android world with this being my first Android phone, so all the terms and jargons are very over-the-top! I love the phone and really want it to work well, I expected great things from the Google phone!
