Unfortunately, the review has been reduced to Lollipop since update my Samsung Note 3 to 0-1 stars. The Gear Fit combines since the update only after you restart the device or separation of the Bluetooth connection again with the phone. Leaving the room and goes more than 10 meters from the mobile phone away, is the connection away. Before the update then the Gear Fit has automatically connected to the phone. This is no longer now. Sometimes it will also lose the connection in the middle of the night. Took my Gear Fit as an alarm clock. This is now no longer. This is too unreliable!
The sleep data can no longer be also transmitted to the mobile phone since the last Gear Fit Manager Update (Samsung Apps).
And also the GPS track with a workout is recorded only the first few meters. That is totally unsatisfactory and frustrating.
I would buy the unit so no way back. And now I regret buying a lot. Only can any advise against it.
I hope that Samsung software problems come to grips with. Thus the device is unusable.
