The Nokia 9 design is nothing new, but the labeling info is still interesting. There will be both single and dual SIM versions of the phone and the Android One logo is present. The phone will support fast charging (5/9/12V, sounds like QuickCharge). Interestingly, the FCC docs show the phone running Android 8.1 Oreo.
As for the Nokia 1 Plus, it will have a microUSB port charging the 2,500mAh battery (the phone will be bundled with a 5W charger). It has a 3.5mm headphone jack on top. There will be single and dual SIM models, both with dedicated microSD slots.
The 1 Plus documents don’t make a fuss about the Android logo, but the phone should be part of the Android Go program as it will have just 1GB of RAM.
