Blurry background images

Hello, when uploading an image it is blurry when seen on my device, but looks good on appinventor working area. I see there are many topics about this issue but all of them are from 4 years ago. Is there anything I can do to have proper images on the real application seen from my phone?

Without knowing the details of your image file (dimensions in pixels, bit depth, size in MB, format (jpg, png, webp) it is difficult to advise - however, it sounds like the image is of low resolution.

This remains an open issue on github for AppInventor.
