I've got a GS4 and a couple of days ago, I get a popup saying there's a software upgrade to download and do it on wifi. So I trot over to Starbucks (my local wifi isn't happening for some reason) and I sit there for three damned hours to get about 30% of the total (which was 115mb). I couldn't sit there all day so the next day I try the fedex parking lot. Now the download starts again at ZERO!! Are they freaking serious? It's not resumable? Who the hell can sit there for six hours waiting for this. I call ATT they don't know nothing. I call Samsung they tell me to download Kies so I can do the upgrade from my PC. WRONG. It does NOT download the upgrade. So I call Samsung tech support and THEY tell me there IS no upgrade yet from 4.4.2. So what did I down in that 35mb of Starbucks? I'm furious right now; I can't believe the only way to do this is via wifi. That's completely insane.
