          err => {
            console.log("cropping error");
            console.log(err);

Describe what you expected to happen:

Same here in iOS, did you find solution?

[linhmimoza]

try displaySize: {width * 4 ,height * 4} It worked for me

I have tried various combination, one thing stood out to me is the cropped image quality is always degraded compared to the input ( which you can see clearly with your eyes)

3.1.0 releases include a new feature: number prop that lets you adjust the size of the picture. That should solve your issue
