My Charge 3 is so dark I can’t see it

[BaileyAnn]

Fully charged my Fitbit 3 is so dark I can’t see it. I have done the restart, both phone and Fitbit, and nothing helps. I followed the info on the Fitbit help page. I go to the sleep/dimmer area and it works for a bit, then back to total darkness. 
Not much point in having a Fitbit that’s too dark to see. Very disappointed

Thank you for visiting the Fitbit Community, @BaileyAnn.

I’m sorry to hear that you are having difficulties to see your Fitbit Charge 3 display. Your time while dealing with this situation is highly appreciated.

Please make sure Do Not Disturb (DND) and Sleep Mode are turned off. For instructions on how to navigate your Tracker, please visit this article.

In addition to the regular restart, please try a long restart:

1. Connect the device to the charging cable. 
2. While the device is plugged into the charging cable, press and hold the button down for 15 seconds. 
3. The device turns on and shows a battery icon. Two vibrations occur: first a short vibration, then a medium vibration. 
4. The device turns off.
5. The device turns on and shows a progress bar and short vibrations occur. The progress bar completes. Note: A total of 7 short vibrations occur. 
6. Remove the device from the charging cable. The device shuts down.
7. Important: Plug the device into the charging cable again. 

You can also try to change the clock face:

• From the Today tab in the Fitbit app, tap your profile picture > Charge 3 tile.
• Tap Clock Faces.
• Browse the available clock faces. Tap a clock face to see a detailed view.
• Tap Install to add the clock face to Charge 3.

Hope this helps.
