The Gear Fit Pro has been in the rumor mill for a while, and recently it surfaced on FCC as Gear Fit 2 Pro (SM-R365), but an official support page went live as well. Although this page is empty at this time, Samsung did not remove it yet, so it would not be surprising to see some details added soon.
Unfortunately, there is only one sketch that was sent to the FCC that shows a design similar to the regular Gear Fit 2. The noticeable differences are expected to be under the hood, with increased step-tracking accuracy and quite a few new sensors. Obviously, Samsung did not confirm any details yet.
Next to the Gear Fit 2 Pro, a wearable known as Gear Sport surfaced on FCC this week as well. Both are expected show up at next month's IFA trade show in Berlin. We will probably hear more about the Gear Fit 2 Pro in the coming weeks, so stay tuned.
