I've found that if I update over WiFi, it fails. A lot. Right now, I went to update the NFL app. It gets to 35% and stops. It's been sitting still now for 10 minutes. Did the same update on my wife's G3 and same results. Then I installed it on my old S4 and it installs fine. I can't uninstall the NFL app though on my G3. I just installed a 43 mb game and it went really fast. It seems to only hang on updates. I haven't had a chance to jump on someone else's WiFi either...
