Tracking exercise incorrectly and unresponsive screen

[SunsetRunner]

I have had my Fitbit Charge 5 for 6 weeks.  It's the 5th Fitbit I have had and so far the worst.  It isn't tracking exercise from the auto recognised list and adds in exercises such as swimming, aerobics, and walking when I am sitting or resting.  The screen is not responsive and it is very difficult to swipe through the menu and at times double tapping the screen does not work.  I have just been on an activity weekend and one day it showed I only did 8000 steps and no activity although I walked, cycled, climbed, and played tennis and badminton! Will Fitbit replace this or will they try to fix it?  They've sent me a reconditioned replacement on a previous Fitbit but this did not work correctly so ended up buying this as a replacement.

Welcome back to the Fitbit community, @SunsetRunner!

Sad to hear about your recent experiences with your Charge 5. As a first possible step to get your device back to normal operation, I'd suggest to restart it by closely following these instructions:

1.) Connect your Charge 5 to the charging cable which has to be connected to a power source.

2.) Press the button located on the USB plug of the charger 3 times within 8 seconds(!), holding each press for about 1 second(!).

3.) Wait around 10 seconds until the Fitbit logo appears.

If this doesn't work for you I'd suggest contacting Fitbit support to get further assistance as your Charge 5 might have hardware issues with it's sensors:

Thank you.  I'll give that a go later.

You're welcome, @SunsetRunner!

I'll keep my fingers crossed.

Hi.  I have tried this a few times but nothing happens when I have pressed 3 times whilst plugged in power.  The screen stays on the charging screen, doesn't restart, and no logo appears.

Thanks for your feedback, @SunsetRunner, although I'd liked to hear something different.To perform this restart procedure, it is crucial to stay with the exakt timing.
If you're sure having done so without success, your device might be defective. Thus I'd suggest contacting Fitbit support for further assistance as your Charge 5 should be covered by their warranty:

Thanks again for your reply.  I have contacted Fitbit who did further testing and confirmed the device is not working correctly.  They will replace it.  Fingers crossed I get an unopened device and not a used one that doesn't work like previously opened devices. 🤞

Keep going with your new device!
