My on wrist calls will not stay connected to my phone

[Klarmstrong]

My Sense will not stay connected to the android phone.  It is very frustrating.  My old Fitbit did a better job.  I switched from a smart watch to Fitbit and have to say I am disappointed in my purchase.

@Klarmstrong Welcome to the Fitbit Community. Thanks for the detailed information shared. 

I see where your frustration is coming from. I'd like you to check the following requirements: 

• Make sure you’re using the latest version of the Fitbit app. For more information, see How do I use the Fitbit app?
• Make sure your Fitbit device is up-to-date. For more information, see How do I update my Fitbit device?
• Keep your phone nearby with the Fitbit app running in the background. Your phone should be within 30 feet (10 meters) of your watch.
• Call notifications must be turned on. For more information, see How do I get notifications from my phone on my Fitbit device?

If you're still experiencing difficulties, follow this troubleshooting. 

Hope this helps.

You will also need Sense Controls for answering a call. 

I would also restart the phone, then have someone call. If this works, then the issue is usually in power management.
