I am thinking of making the change. I have an s4 from O2 which I think is quite slow. I have recently been using the moto g phone and it feels so much faster and easier to use with out any manufacturer software like Samsung rubbish loaded onto it and being just plain android. I would prefer my s4 not to have any samsung software but don't have the confidence or know how to root it myself. Has anyone made the change ? Any regrets ?
