Hi, I have a Samsung Galaxy S4 and I recived a notification telling me there was an update but diapered before I could click. Now when I check for an update. I get a message about how the update servers can't be reached roll out limit reached. Try later. I have talked to samsung and they said that if I go to best buy they will update my phone for me so I don't have to go ota. Is this correct? My phone runs on us cellular.
