Bumped into Florian Jensen (@flosoft) whilst out and about in London doing some 4G speed testing. He has a Samsung Galaxy S3 which he had rooted with CarbonRom based on Android 4.3. He wanted to increase the phone’s performance and improve battery life.
I was surprised to see that there is a very noticeable improvement in speed. The SGS3 running CarbonRom was faster than the SGS4 which has a more powerful processor (s) running Samsung’s firmware. We did some videos yesterday that illustrate this. You can read Flo’s post on what he did here. Unless you are a serious geek (which I realise that quite a few of you are 🙂 )I wouldn’t necessarily recommend doing it yourself.
