Although there is a lot of coverage of the Samsung Galaxy S9 one of the interesting spaces that has been vacated by Google and Apple is the well built mid-range mobile device.
Oneplus has a great phone in the mix but the recent scandal of credit cards being stolen from their online ordering system and the reluctance to update their devices quickly may present an opportunity for Nokia.
Nokia has joined the Android One programme and, looking away from the premium Nokia 8 Sirocco, the Nokia 7 Plus seems to fit the space that Google Nexus devices used to sit in. When you add in the completely stock Android implementation then it really represents some value in that space.
Nokia is certainly back from a European viewpoint. I think the Nokia 7 Plus is the most interesting of all their announcements.
