Even though Android 4.0 can be considered fairly new, Google has released an Android 4.0.2 update for the GSM Galaxy Nexus. If you’re still on Android 4.0.1, you will receive an automatic notification reminding you to update your phone to 4.0.2. If not, you can do it manually by following this:
Go to Settings > About Phone > Software Update
The update has included important bug fixes so it’s best that you update your system. The update has a total size of 8.8MB and is available OTA.
If you’ve already updated your phone, let us know what you think in the comments section below.
