I got a used I337 S4 and have been using it on ATT no problems. I rooted it (towelroot), initially just to make it easier to back up some application data but eventually I plan to debloat the thing. Probably will stay on stock ROM unless I have a compelling reason to switch.
My question is, now that I have a rooted device, do I have anything to fear from possible OTA updates to 4.4.3 or 4.4.4, updating the OS and making me loose root. And if I do need to be concerned, what is the best way to block such updates from happening, until such time as a new root is (hopefully) developed.
Sorry if this is a basic question... I'm still learning my way around these things.
