I got a gear fit but unfortunately I can't download the gear fit manager because it is available in the galaxy store and I use a Huawei who can help me?
You could drag the app onto your smartphone by downloading the app from the galaxy store or elsewhere.
On the Samsung HomePage, as far as I know, there are all samsung apps as apk, also believe in Galaxy apps.
Called "Gear Fit Pro Lite - (for Gear-Fit 1)"
Checked and found in GoogleStore
I searched and found but unfortunately no download
