After the announcement that the Galaxy S3 and S4 are going to receive their Android 4.3 updates in October, many asked about the Galaxy Note II and when it is going to receive its update. Apparently the Android 4.3 update for the second generation phablet will also hit in October, but right now, the AT&T variant is seeing a minor update. Nothing to be too excited for. This update, although 165 MB in size, is only looking to update Google apps and AT&T pre-installed apps. Also there is no incremental step up in Android versions, so you must continue to remain patient. Let us know if you have received it.
