Known issues when installing official google ICS on Galaxy s2 I know Google issued out an official ICS rom for the Nexus S devices and I'm wandering if the same rom (or any other Google official variant) will properly work on my Galaxy S2 or will there be any notable issues?!

I'm asking because I'm quite fed up with the Samsung's stock roms (both GB and ICS) and I really want to avoid 3rd party roms such as CyanogenMod.
Unfortunately, that's not how it works :/

Though we would all love the official ICS versions rolled out to the Nexus S and Galaxy Nexus devices, they are designed specifically for the hardware of those phones; thus is the nature of Android.

So, if you want something similar, the only way you will be able to get it is a 3rd party ROM. The only official OS versions for each phone are the ones rolled out by each provider, in your case, Samsung.
