My Blaze will not sync with my Android  for the past 4 days.

The usual things to try when you get syncing issues are:

• restart phone
• restart fitbit using this procedure: Help article: How do I restart my tracker?
• restart fitbit a few more times (it doesn't always work)
• "forget" the fitbit in the phone's bluetooth settings
• go through fitbit's troubleshooting guide at: Help article: Why won't my Fitbit device sync?

If none of those ideas work for you then it’s probably best to contact customer support via: contact.fitbit.com

A couple more things to try. 

• Check for phone updates
• Check for Fitbit updates
• Go into phone settings / Apps / Fitbit / Storage / Clear cache
• While in phone settings let's Force stop the Fitbit app. Swiping of screen will not shut down the Fitbit app. 
• Shut down phone, this is the only way to reset a hardware error. 

For me one of my last points usually get me up and syncing.
