Sense won't turn on but keeps vibrating

[Garygila]

Hi,

my sense was working perfectly until now but all of a sudden it will not turn on, screen is black but the sense keeps vibrating.

the sense was on a full charge. I have tried to connect the charger cable and sync with the app but nothing has helped.

Hi, @Garygila - it's possible that the watch it clock face has developed a fault.

In the Fitbit App Gallery tile if the watch is syncing change the clock face and see if this helps.

If not, hold the button for 10 seconds till it stops vibrating and vibrates again and wait for the logo to appear, if it does.

Hi there, @Garygila. Welcome to the Fitbit Community Forums.  Thanks for trying to troubleshoot the issue with your Sense before reaching out.

If the issue is still happening, please try the following steps:

• Clean the charging contacts on the back of your Sense using the instructions in How do I clean my Fitbit device?
• If the error "insufficient power source" appears on your device's screen, remove other devices plugged in to your power source, or plug your device in to another source.
• Try a different USB port or a UL-certified wall charger.
• Check the alignment and try reconnecting your device to the charging cable. For more information, see How do I charge my Fitbit device?
