Android 4.3 was finally made official, and usually updates start rolling out that very same day. It is taking a little longer for the update to hit even Nexus 4s out there, but word has it that international Galaxy Nexus users have started to receive the Android 4.3 update.
There have been early builds for the Verizon Galaxy Nexus that have been conjured up, which of course needed to happen because we know how Verizon loves to take their time when it comes to updates. So I would keep an eye on your system updates in the next couple weeks. First the newer Nexus devices will receive the update, then the good ole’ Galaxy Nexus will get its update next. Let us know if you see anything.
