HMD Global is definitely preparing for more after the recent releases of Nokia 6 (2018) and Nokia 7 if based on these leaked tweets from @evleaks
First off is Nokia 1 which might be an entry-level offering based on it's 16:9 display, a bit small form factor and single rear camera
The surprising one, the known global brand will venture for the first time for Android One with Nokia 7+ with 18:9 display, dual main cameras, Android One marking and rear fingerprint sensor
No hints yet on the possible releases but we might gonna see these handsets in the upcoming MWC 2018 in Barcelona
