I installed some apps, including My Story, from the Samsung store, and had to remove them when they completely hung up during the registration process. After uninstalling them, my phone seemed a little sluggish, and some apps glitchy or less responsive. I decided to do a factory reset. However now things have gotten a little worse. My screen brightness when on Auto constantly gets max bright and then dims, only to go max bright seconds later. Facebook app doesnt work properly ( worked flawlessly prior, there has been no update recently ) and some other lag issues, like when opening my email app, it sits with a black screen for a second or two before popping in... all in all Im worried that I have altered a system file somewhere on accident, and the factory reset doesnt seem to fix this as it only deletes user data.

My Question: Is there a way to truly reinstall android and completely factory reset it? I want a fresh install of the OS and everything. I am using a Sprint GN2
