Sorry for the more detailed question I do not understand which is the difference between the normal format and the GT3 format. I also google PNG GT3 format but seem no results at all, so could you please tell me which is the differences between those formats. Thanks.


I don't know about the ...

Thanks so much for your explanation,
But what is GT3 in your sentence mean? What is it stand for?

> "What I understand is that it is an image file that GT3 uses."


Amazfit GT series

GT is the model name of the watch. I don't know what it stands for.

GT3 is the 3rd generation of Amazfit ...

So GT3 format means it supports for Amazfit GT 3rd generation only, it does not a standart of PNG that can use global by another application, another place.
Thanks.

That's right, PNG(GT3) doesn't use standard PNG. It's made for Amazfit devices.
But not only GT 3rd. it's use on some GT 4th too ...
