A listing on the US FCC website for the Nokia 9 appears to reveal most of the specs for the incoming flagship.
The leak lines up pretty well with what we've seen before, which is essentially a Nokia 8 spec sheet. Although these specific details aren't listed, the rumour mill has suggested the Nokia 9 will have added waterproofing, camera improvements, and an 18:9 aspect ratio display.
The chipset is confirmed as a Qualcomm Snapdragon 835, but RAM isn't listed. We do see 128GB of onboard storage, Android Oreo, and an LG-made 5.5in OLED display.
The primary camera appears to have similar specs to the Nokia 8, with a 12MP and 13MP dual-sensor setup, however, this doesn't rule out the rumoured camera improvements over the current lead model as we may be looking at wider apertures or the increasingly popular software algorithms in terms of improving picture quality.
The last bit of info is an 3,250mAh battery with quick charge.
