The Samsung Galaxy Note 8 model number was SM-N950 so when an SM-N960F showed up on FCC, most people probably could figure out which device the model number is for.
If this is indeed the Samsung Galaxy Note 9, the only thing that this would confirm is that the device is coming. It does not reveal any more details about the device so we will still have to depend on the rumors and leaks for more information about the upcoming device.
According to the reports, the Samsung Galaxy Note 9 specs will not be a huge jump from the Samsung Galaxy Note 8 but some of the upgrades that we can expect to see are the new S Pen which will come with a few new upgrades but details about the actual upgrades are still pretty scarce right now.
It has been speculated that the Samsung Galaxy Note 9 will be unveiled on the 9th of August this time which means the wait could be over soon.
