There is a general issue with Fitbit Inspire 3. I contacted first the support thinking that there is a hardware issue, the screen behaved like the screen connector or something had a malfunction. They guided me to do a factory reset which temporarily worked, also they guided to not use 3rd party band faces (clock galleries) but I always used the original one. Like many similar topics closed I face the same issue after more or less 1 month from purchase. Lately I see a very big difference in pulse reading, so despite of screen issue the sensor became inaccurate in it's readings. I was thinking that I am an exception but I see that there are many people with the same issue. Now I understand why it had a big drop in price on Amazon. Even changing the band face still flickering, it seems that in the end factory reset won't make a big difference. Either there is build quality either the firmware is buggy.
