I have not updated yet but noticed all the sudden when I launch mobile hotspot it clearly calls it self "3g mobile hotspot". It used to say 4g. Last time I used it was a couple weeks ago. Are they blocking 4g to make you update or something? I maybe random rebooted once a week, so I don't want to risk updating till I need to, and know the update is ok. The hot spot says its still free, but only 3g comes up. I also tried swicting the LTE on/off but nothing changed. Oh also, does this update make it harder to root, i am on the fence about rooting. I don't want to make it harder on myself.
