Ollin adapter effect on phone compass

[Dawson]

Does anybody know if the Ollin adapter has magnets in the actual phone case? Or just on the eyepiece. I know that magnets in a bino harness can really mess with navigation on onx. I was wondering if the phone case would do the same.

Samsung 23 just in the eyepiece, didn't notice it messing up navigation in onx
