Looks like the Android 4.1 software update awaited for so many S3 users has begun in eastern European countries at least in Poland as users have reportedly receiving the Jelly Bean upgrade for their Samsung GALAXY S III through Samsung Kies software tool.
The new build version I9300XXDLIB is apparently faster than DLI8 but as a users said on XDA forums “there are still lags when browsing widgets, and the volume down button doesn’t allow for silent + no vibration.” There are some improvements withing the GALLERY app which after the update feels a little bit smoother, the USB charging is now back to the way it was and it should be, the third-party launcher transparency bug now fixed with this release. There are other fixes and improvements that we arent aware yet if someone finds any other improvements do let us know in the comments section below. Enjoy
Update: Samsung has confirmed to TechCrunch that 15 other devices will receive the upgrade soon:
Following soon will be Jelly Bean upgrades for GALAXY Tab 2 7.0 & 10.1, GALAXY Note 10.1, GALAXY SII, GALAXY Note, GALAXY Tab 7.0 Plus, GALAXY S Advance, GALAXY SII LTE, GALAXY Music, GALAXY Chat, GALAXY Ace 2, GALAXY Beam, GALAXY Ace Plus, GALAXY mini II and GALAXY S DUOS.
