My Blaze will not sync at all - I have restarted, uninstalled the app on my S5, then reinstalled, turned off bluetooth etc, nothing will work. I deleted the Blaze from the app and now it keeps trying to connect but just won't find it at all. I do have the new updated Blaze firmware from the 17.8.401.3.
Any other ideas??

Welcome to the Community Forums @SunsetRunner! 🙂
I'm sorry you're having problems getting your Blaze to sync 😕
Were you able to get it to work or are you still having problems? I'd recommend following @bb-8's advise of restarting it at least 3 times and if that doesn't work, to try on a different device and see if that works.

Hey there guys @tibi01 @TheLipMixtress. Great to see you both in the Community Forums! 🙂
I'm sorry you're having problems with your phones not syncing properly. I can recommend something else, it's setting up your trackers as new devices. For this, it would be worth restarting your trackers again. Make sure you're doing this by pressing the left and lower right buttons for 10-12 seconds. This will make your tracker to reboot and after that, you can proceed with setting it up as a new device.
For this, go to the Account section at the top right corner on the Fitbit app and select the option that says "Set up a new device". Follow the on-screen instructions and once you're done, your tracker should be syncing without a problem.
Hope this helps. Let me know if you need more help!

Best AnswerThank you for the answer.
This helps, sometimes.
But sync issues are back almost every 4 days. More often helps to remove pairing from BT list.
Last times it was really annoying: Both phone and the watch were restarted and adding new device still failed. 2 times. Also Fitbit app was killed 2 times. Still the tracker was not found. Finaly after ~20 minutes the tracker was detected.
And when finally it was working syncing was still slow. It took ~2 minutes to upload data. When comparing with MiBand2 the sync tooks less then 10 seconds.
Best AnswerHello, I am experiencing issues with getting my blaze to sync with my iPhone also. I find that after I charge up my blaze I have to re set the blaze by pressing the left button and lower right button to allow my phone to sync with it.
I go through the whole process you advise about closing apps, switching my phone off etc... and this is the only way to get it to sync.
Is there something wrong with my Fitbit alone or is there an issue with all of them? If it is wide spread what are you doing to correct it?
From my own circumstance, am I damaging my Fitbit having to reset it after every charge up in order for it to sync with my phone?
thank you.
