I get it - sometimes it is necessary to update the software. OK. But why the hell can't we use OTHER APPS until the Play is updated? It is completely irresponsible as it renders the phone unusable for some time without any notification beforehand! Real life scenario - I was in the middle of nowhere checking in the hotel  I had my reservation code and other information in the mailbox. But guess what? I was not able to access the Gmail  because the Play Store was not up to date! So  in order to read one email I had to download 30MB+ update in place where was barely any mobile signal and almost no internet connection at all. Terrific work Google! People use their phones outside their homes and WiFi covered areas too.
