Been reading AC articles via the app for quite some time now and just decided to join the forums to further embrace my closet phone geekness.
Currently on a Verizon Galaxy S4. Ran it stock for about a year now and just rooted using Saferoot. Deleted as much bloatware as I felt safe doing using Titanium Backup and System App Uninstaller. That's about as far as I've delved into root level customization.
Also just threw in a microSD I had kicking around and started moving apps to that to free up some space.
So I'll spare the questions about what to do next and get lurking the S4 forums for info
