I have an Samsung Galaxy Ace that came preinstalled with Android v2.3.4 (Gingerbread I believe)
I've searched the internet everywhere and couldn't find a way to do so that gave clear instructions on what to do.
But I would also like to ask, if I was to update to say 4.1 (the latest I believe) would the phone then start to lag as it is not such a powerful phone. (800MHz CPU + 300MB RAM)
Thanks heaps!
