Blaze undercounting steps 50%

[Moogee]

Hi, just got a blaze from a charge hr I've been suspicious it hasn't been accurately recording steps. All my data is accurate and I've reset the device a few times as see on other posts but it is still doing it. It is missing about 50% of my steps. I'm considering taking it back for a refund but really would prefer to resolve the issue. Any ideas?

A warm welcome to the Community @Moogee. Thanks for troubleshooting this inconvenience by yourself. I recommend restarting your Blaze a couple of times more and also check if your stride length information is updated.

To measure your stride length do the following:

1. Go to a track or some place where you're sure of the distance.
2. Count your steps as you walk across that distance, making sure you travel at least 20 steps.
3. Divide the total distance (in feet) taken by the number of steps to get your stride length.

To adjust your stride length from a computer, click the gear icon in the top right and go to Settings > Personal Info. The stride length fields are in the Body Info section. If you use the Fitbit mobile app, go into the app and turn off Set Automatically under the Stride Length setting.

I hope this helps, let me know the outcome.

Make sure you set the dominant/non domiant hand.

I found using my non-dom better

My blaze is only about 2 weeks old and it is undercounting my steps by about 30-40% quite consistently. I have reset it three times and it is set for and on my non dominant wrist. I am not concerned about the stride length. Can you tell me if this is a problem with my device or the software? And how I can fix it? Thank you.

I just got back from Ireland.  My husband wore my Charge HR because I bought a Blaze a few months ago.  Not only did I take every step my husband took; I did a lot more walking, because he often rests while I explore things.  Every day, my step count was thousands of steps lower than his.  I was suspicious of the Blaze before this trip; now it is documented as severly undercounting.  Very unhappy with this Fitbit.

@AlejandraFitbit Hi! Could you please explain how and why a different stride length will make the STEP COUNT more accurate. I still don't understand.

@KerryKay have you done a simple walk test?

Put your tracker into its tracking mode

Start on the left goot snd count every right step up to 100.

You have taken 200 steps 

What does the tracker say?

[DebbieK60]

I do not think that the stride length would affect the step count. It would affect only the distance. In a previous answer someone mentioned how to adjust that, so just thought I would mention it is not an issue for me.

Looking to get this resolved as it is no fun to see it creep along.
As it stands now I just sprained my ankle last week so not doing many steps at all.

Yes. I have tried this many times. Sometimes undercounts 40% bug usually by much more say 40% For 500 or more steps and even tried to move the strap higher up on my wrist but then I have to make it very tight or is slips down.
Tried it without moving arms and moving as normal and it does not seem to get better.
