Charge 3 is barely responsive after app update

[TWeisse]

Yesterday (April 22, 2020) it looks like the Iphone Fitbit was updated. Since then, my Charge 3 is barely responsive. I have restarted my phone a number of times and was able to force restart the Charge 3, but it still runs poorly. Any suggestions?

Hi @TWeisse. Welcome to the Community Forums. I'm sorry for the delayed response.

Thanks for letting me know about your Charge 3 and the steps tried on your own. Let's work on this together! Before anything else, by barely responsive do you mean that your tracker doesn't respond to swipes or when pressing the button? Was the restart performed as described in this help article?

In the meantime, I'd recommend to perform a long restart with the following steps:

1. Plug your device back into the charging cable and hold the button down for 15 seconds.
2. The device turns on and shows a battery icon. Two vibrations occur: first a short vibration, then a medium vibration. 
3. The device turns off.
4. 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. 
5. Remove the device from the charging cable. The device shuts down.
6. Important: Plug the device into the charging cable again.

At first the responses to swipes or button presses were slow. And at this point, it is unresponsive to any input from me except right after a forced reboot using the help article you linked to. It is responsive after the reboot for about a minute and then locks up again.

The long restart does not behave for me as you describe. I get the results of the standard reboot (smiley face at about 10 seconds); keep holding the button; the display turns off - no additional vibrations, no progress bar.

I accidentally started another thread about this topic because I didn't see this one in my subscriptions. it is located here:  https://community.fitbit.com/t5/Charge-3/New-version-of-app-now-Charge-3-is-unresponsive/td-p/420090...

You will see in that thread that the Charge worked properly for a few hours until I tried to start an exercise. At that point, it asked me to pair to Bluetooth. After paring with Bluetooth (selected OK on the screen that popped up on my app) it locked up again.

I have tried re-installing the app; deleting user data (on the Charge 3), removing the Charge 3 and re-adding it.

Thanks!

@LizzyFitbit - I replied to the thread that the long restart doesn't work as explained on my Charge 3.

What are the next steps to try? Or is my device toast?

I contacted support. The tracker failed the long restart and they said there's nothing more to try. My Fitbit is under warranty and a replacement order has been placed.
