Plugin struggles to read custom QR code

[lkjimy]

Describe the bug Plugin struggles to read custom QR code. In my case a very simple QR as shown in the video bellow. It takes forever to read, and is necessary to fill the field of view of the camera with the QR for it to read it. All android users seem to have this issue, iOS users, not so much. The official demo shows the issue.

I also tested the custom QRs with, and without a logo in the middle, using the native phone camera, and was able to quickly read every QR.

Versions 2.x and 3.x were tested with the same results.

To Reproduce Try using the official demo.

Screenshots I'm generating a QR with ~33 alphanumeric chars.
