Sense screen not responding

[Guil777]

Hello there, 

  This week after spending time on a pool. I was not even swimming my Fitbit sense stopped working. For a while it would show a red Exclamation mark and a triangle. Now it does not show anything, I cannot connect to the app but if I sharge it it keeps shaking.

Hi there, @Guil777. Welcome to the Fitbit Community Forums. Thanks for bringing this to my attention. I'm sorry to hear that your Sense is not responding. I understand your concern, I will do my best to help you with this!

What do you mean by shaking? Is it non-stop vabrating? Have you tried restarting your Sense? See, How do I restart my Fitbit device? 

Regarding the screen not responding, please try to manually sync your Sense by tapping your profile picture >  your device image > Sync Now.  By doing this, a firmware update banner should appear.

If Sync Now doesn’t show an update banner, please tap your profile picture > your device image > Gallery. The app should show a popup to install the missing apps to install the missing apps and recover the device. If the firmware update banner does not show, press and hold the side button for 10 seconds until the Fitbit logo appears on the screen, then release the button. For more information please visit How do I restart my Fitbit device?

If none of the above works, please do a manual factory reset: Press and hold the button for about 8 seconds until the screen turns off and vibrates. When you feel the vibration, release the button, then immediately press and hold the button again. Wait for the Fitbit logo to appear, then as soon as the logo disappears, release the button, then press and hold the button again. When you feel the vibration, release the button, then wait for the watch to complete the factory reset.
