Hi, has anyone experienced an issue with PNG image that taken from iphone ?

We tried to read QR information from gallery, using .PNG image, but analyzeImage return false. Then when i tried to convert the image to jpeg, the image are able to read.

Some images are in PNG format, as it usually was directly taken by the user using screenshot.

Using mobile_scanner 3.2.0

I'm experiencing this same issue. We might have to convert the image first as a workaround for now.
