Wi- fi takes some bout 25 - 40 min. depending on internet speed. But I had the problem when screen went off.. The download was set to pause. Settings - wi-fi always ON even sleep mode, but still it disconnected when the phone was left alone. I've set the backlight to never OFF, pluged to charger and it went well. Little stupid thing that screen needs to be lightened to download all the stuff... Google play works fine, update, accept, screen off, all downloaded and installed. Maybe a software thing with this Wi-Fi operations.
