Since the Samsung A8 update several months ago I have not been able to receive notification on my charge 2 for my text msgs, emails and calls. Sometimes it takes several tries before it would sync. Now there is the Firmware update that would not complete.
I'm having the same issue. My A8 updated in April and I've been unable to sync my Fitbit with my phone ever since. I don't even bother to wear it any longer since I can't track my progress or update the time and settings. So frustrating!
