I can't change the language on my Charge 3?

[SunsetRunner]

I am so over Fitbit. I have been a user for a long time but recently the problems are just getting worse. I really hate that just because I am located in Japan everything is in Japanese with no option to change it!! 
I had trouble last year with a screen that got lines now it has gone black and none of the solutions work! 
No more. I am going with something else from now on.

Thank you for visiting the Fitbit Community, @SunsetRunner.

I'm sorry to hear about the difficulties you experienced. Thank you for the information provided.

Changing the language on your phone changes the language in the Fitbit app. For instructions on how to change the language on your Fitbit Charge 3, please visit this article and open the menu "How do I change the language on my Fitbit device?".

To try to resolve the issue with the lines on your Fitbit device's screen, you can perform a regular restart and if necessary 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. 

In addition, if your Tracker is syncing you can 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.
