I know nothing about Kies and how it works. I've seen a lot of people complaining that they have had real trouble after updating via Kies but I would like to update soon. Does anyone have any thoughts please?
If you are uncertain get it done under warranty at a service center. Back up first (be aware you'll lose s_Memo etc), do a hard reset before and after (as per NeoGrandizer's post #6 and #16 at link below)
4.1.2 updated battery drain
Personally, being ultra cautious, I remove both SIM and SD cards.
