Hi there @PankajChopra, good to see you are visiting the Fitbit Community. My apologies for the late response. I was reading your post that you are unable to pair your Alta HR. How it goes so far? Is the issue still persisting?
If the issue persists, please refer to this article: Why can't I set up my Fitbit device?
Keep in mind the Samsung A8+ is not listed as compatible. The full list of compatible devices with confirmed compatibility can be found at fitbit.com/devices.
If a device isn’t listed it doesn’t mean it won’t work with a Fitbit tracker or smartwatch. We routinely test new devices to ensure full compatibility with Fitbit devices and the Fitbit App, and are constantly working to confirm compatibility with new phone models. A majority of Android phones running version 4.4 or higher will work with our products, however we cannot guarantee optimal performance on devices for which we have not tested and confirmed compatibility.
See you around and keep participating in our Community.
