Hi, I have had DROID RAZR maxx as well. But about 6 months ago i changed it for galaxy s3 and it was already an improvement that made me happy. The only thing that i missed about RAZR was huge battery life which was even better as phone was only 2qore proc.. and after 2months of using s3 i changed it to note2. So i am feeling your dilemma as to make the switch or not. And i say do it if you have the means. You will not get disappointed at all.
