pcmanrules: I gave up a long time ago and went to paranoid android on my S3. Selling it now as I have upgraded to a Note 2. Again I use Paranoid Android rom which even supports the S Pen.
Yeah I am on the verge of flashing my AU vanilla S3 with an official Samsung ROM from the UK. It will likely be identical to what they eventually release for my phone in AU as its not carrier specific. But I hate that it has to come to that.
At least the good think about flashing an official rom is that I don't have to root.
