Last month, HMD Global officially revealed the Nokia 8, its first full-fledged Android flagship smartphone which is now available in select markets. The device hasn’t been released in the U.S. yet, but a recently spotted FCC filing hints at some upgraded specs.

Nokia Power User spotted the FCC (Federal Communications Commission) filing for Nokia 8 variants with model numbers TA-1004 and TA-1012. Both of these variants are listed for the U.S. market and the devices appear to have more RAM and storage than what's already available in Europe.

The two Nokia 8 variants listed on the FCC filing feature 6GB of RAM and 126GB of storage. This falls in line with previous reports claiming that the U.S. version of the Nokia 8 will be customized specifically for the market. For comparison, the European version of the Nokia 8 only has 4GB of RAM and 64GB of storage.

In addition to increased memory, the two U.S. Nokia 8 variants will have the ANT+ feature and WCDMA Band IV enabled. The ANT+ feature will let Nokia 8 users monitor fitness and health data in real-time, according to Phone Arena.

When HMD Global first announced the Nokia 8 in August, the company didn’t specify if the handset would be available in the U.S. With the Nokia 8 already spotted at the FCC, its release in the country now appears to be imminent. The question now is when exactly will HMD release the Nokia 8 stateside?

Yesterday, Nokia was asked on Twitter on when will the Nokia 8 arrive in India. Nokia responded by saying that the Nokia 8 "will roll out globally this month.” HMD has already confirmed that the device will indeed arrive in India on Sept. 26 in the form of media invitation for a launch event, as spotted by Android Central.

HMD Global appears to be releasing the Nokia 8 in waves rather than making it available worldwide in one go. The device’s arrival in India marks the second wave of HMD’s global rollout.

It’s possible that the U.S. will get the Nokia 8 sometime during the second half of October. This is speculated to be the timeframe for the third wave of countries to start receiving the Android flagship smartphone.

As a refresher, the Nokia 8 features a 5.3-inch LCD Quad HD 1440p display and is being powered by Qualcomm’s Snapdragon 835 processor. This is the same processor that’s inside the Samsung Galaxy S8, Galaxy Note 8, LG V30 and the OnePlus 5.

The Nokia 8 also features dual Zeiss cameras on the back with 13-megapixel sensors and f/2.0 aperture lenses. There’s also an impressive 13MP front-facing camera. The unique camera feature on the Nokia 8 is what HMD Global calls Dual-Sight, which allows users to take photos and live stream videos with the rear and front cameras simultaneously. HMD is also trying to start a trend by giving the Dual-Sight feature the nickname “bothie.”
