Those of of you might already installed the leaked Android 4.2.1 Jelly Bean i9300xxufmb3 and found something a little bit annoying, you can try to restore back to official 4.1.2 I9300XXEMB5 which is rather very smoother than the leak version. Those who never tried this latest update, you can manually upgrade too.
The 4.1.2 Jelly Bean will be the last update for the Galaxy S3 for a while but the odds are high that the Galaxy S3 will benefit the Android 4.2.1 or 4.2.2 update after the launch of the Samsung Galaxy S4. Maybe this is due to Samsung Galaxy S4 marketing campaign, either you like it or not we should wait. The official Android 4.2 update is too close, the leaked 4.2.1 builds is a full- proof of it’s close completion and there are lots of custom build ROMs based on 4.2.2 AOSP around. So, there is nothing to argue and worry about but the only questions remains is when?.
