I do not see how the phone checks for updates. You just select "System Updates", and a blank screen with small print saying "your system is currently up to date". Now how do I trust that phone knows this? And I can't manually refresh so I can update it. There is no sign that it even checks, because nothing happens. It is instant when I tap "system updates".
Maybe it checks for them in the background? I'm still not familiar with the way Android works, mostly because I'm very used to the iPhones's OS.
