I have my S4 rooted using towel root, but I honestly dont do much of anything I need it rooted for. I was just bored. I do use my phone as a hotspot daily, using the paid Foxfi app. I've put off grabbing the new verison update that was pushed oout a week or so ago, just to make sure there wasn't anything I needed to do before i update. On my old phone, I had an paa that temp Un-rooted the phone, then after an update Id hit a button and it would be rooted agiain Not sure if I should do that ? Or even what that app was? Thanks!
