How to have clearer images with cocos creator

Cocos Creator
#1

Hi devs
I use cocos creator 2.3.3, since I use my import images via figma, I realize that they are not sharp like on figma and I wonder how to make good quality images to integrate on cocos creator? I tried TexturePacker I don’t really know how to use it to the max? Anyway, I hope someone can give me some answers.
Also, I noticed these images don’t have the same color vibrancy on different Android mobiles.

Here are visual elements that I have already implemented by modifying the scale and the size too

Here is a design on figma

Maybe figma compressed the image quality when exporting, it depends on figma’s export settings.

This is a normal phenomenon, different phones support color is different, not just your image is such.

You may have set the mipmap of the texture, which will make the image look blurry.
Also if you are using compressed textures, it will make the image quality degrade.
