Screen, sleep and alarms difficulties-Charge 3

[ThistleShifter]

I got my Charge 3 as a Christmas present 2019. Like many others I am now having problems with lines across the screen face. I will try a hard reboot and let you know. Also can't seem to set any alarms! As in the App is installed but having no luck doing anything. Also won't record sleep patterns. Any help welcome x

Welcome to the Fitbit Community @ThistleShifter.

I'm sorry to hear that you are having difficulties with your Fitbit Charge 3. Thank you for the information provided and for trying to resolve the issue before contacting us.

If after restarting your Charge 3 you are still experiencing the same issues, in addition to regular restart you can perform a long restart by doing the following:

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.

Since the last firmware update, you can set your silent alarms from your Fitbit Charge 3 or through the website at fitbit.com. For instructions to set your alarms, please visit this article.

Please make sure that you are following our instructions to record your sleep. If this doesn't work, please let me know if you are having difficulties to see your sleep patterns, sleep stages or sleep score.

If you have any question, please let us know.
