Here is a link to the basic changes.
What I can confirm from using it is:
- Battery life is a LOT better and this is without rooting (Android process now only chowing about 15% of the battery as compared to previous 50~60%)
- Home screens now have endless loop (You can go from 1 to 7 and vice versa)
I would highly recommend this update to anyone not wanting to go the custom rom route like me![]()
Why don't you want to go the custom ROM route? Either way you have already voided your warranty. They will most likely check which version of the ROM is on your phone and notice that they have not pushed that version out on Kies yet.
