It has been said that the GT-i9350 version of the Samsung Galaxy S3 is to get an update to Jelly Bean 4.3. Residents of Germany will be the first to get their hands on the update before it then moves to Spain for those with Vodafone. Device owners are able to get hold of the update using Samsung Kies or OTA. This has led to some owners not wanting to wait for the update and wanting instead to install it manually. It seems the update it wanted desperately by some owners to fix bugs that came with the prior update.
Anyone wanting to install OTA can go to Settings – About device – Software update and make the update.
The update can also be installed using Kies with a desktop computer by plugging the device into the computer. Kies will pop up and ask the owner if they wish to update. As with any update owners are advised to back up their Samsung Galaxy S3 LTE before updating.
