Updated from 2.3.4 to 2.3.6 today. OTA & not thru KIES
. Downloaded in less than 5 minutes but the installation took at least 30+ minutes. In fact I was wondering if the update had got stuck midway but it went thru slowly (patience in not my strong point). Like others have mentioned I noticed this (immediately on starting).
[*]Home screen clock display shifted to bottom.
[*]New unlock system. Can be confusing as there no direction on what to do.
[*]No problem (so far) in browsing thru the gallery.
[*]There is a slight different in accessing the contacts/sms/logs. Basically the first three buttons frm the left side.
[/list]Had taken a backup of everything but I didnt loose anything.
Will update in due course as & when I notice any upgradation/degradation in performance or other changes.
