Ace 2 keeps turning off and won't respond to taps

[sew1980]

My son's new Ace 2 he got for Christmas keeps turning off.  It doesn't respond to tapping the screen, and he has to use the button on the side every time.  Then there is a smiley face, and it hasn't tracked any of his steps.

Welcome to the Fitbit Community, @sew1980.

Thank you for sharing the details of the issue you’re experiencing. I would like to advise that the tracker’s screen turns off when not in use. I recommend doing the following:

1. Press and hold the button on the tracker, check if the Screen Wake is turned on. 
2. Confirm the steps to restart the tracker: How do I restart my Fitbit device?
3. Change the clock face:  

• With your tracker nearby, from the Fitbit app dashboard, tap the account icon> Ace 2 tile.
• Tap Clock Faces > All Clocks.
• Browse the available clock faces. Tap a clock face to see a detailed view.
• Tap Select to add the clock face to Ace 2. Sync the tracker. 

Let me know how it goes.
