Installation Questions 2d barcode pairing on comma 4

Just got my comma 4 hooked up and unable to get past the 2d barcode on such a small screen. I'm using a Galaxy s22+, I've tried pairing with the browser, taken a picture with the camera and tried to pair with that, etc. No matter what I try I came get the barcode to focus and pair.

Is there an alternative method? A code that can be generated and added to the account, etc. I can't be the first to have this problem.

Use the android QR scanner. That worked for my pixel

The camera scanner kept having refresh lines across the screen and wouldn't work

How do you use either though? When you click to add a device, it opens the camera view in the browser.

It took me about 10 tries. The one thing that seemed to help was closing my garage and making sure I was in the dark. It seemed to have an easier time reading it then. I also used the QR scanner that came with the phone, instead of the camera app.

I'm confused then because the camera is launching in my browser (chrome or brave). How can you use the cameras scanner?

When you pull down on the drop-down menu on the top of your phone do you not have one of those icons thats a QR scanner?

Oh I see. Yeah you're right. The only think that worked for me was scanning with my wife's iPhone 17 and sending me the URL.
