With the jelly bean 4.3 upgrade in galaxy s3 is running smooth and also is now working smoothly with kies 3 official.With earlier upgrades my phone speed syncing with my pc(kies) so I had to use 3rd party software for that.all that changed for the good and more when I upgraded my firmware to jelly bean 4.3.2 now it's syncing with kies 3 given on Samsung's official website.one needs backup of data to outlook etc
