The S3 was almost a non starter. It turns out the Infuse vehicle charging mount just happens to fit. Not as smoothly or one handedly as the Droid X and it's factory mount, but it was decent and over the last year it hasn't ruined or worn the finish of the S3 after hundreds of mounts and dismounts. Otherwise, I would have had to send the S3 back and go with another Motorola. So now it's the beginning again. I have searched and see no vehicle charging mounts that will charge the S4. Since the sizes are very similar, it's possible the Infuse dock will still work. Has anyone tried it by any chance? Mounts like the iBolt where you have to plug in a separate cable are a non starter.
