I don't have the "auto download over wi-fi" option in my phone. Does anyone else not have one and does anyone know the reason why?
@Operateur, It can depend of your carrier. Not all phones can download updates via cellular data.
@kamil40013 It can also be downloaded via mobile data. The thing is that I don't have this option in my phone at all, so I can't know and maybe turn off auto download.
