@soapdog I am in the midst of trying out both GrapheneOS and LineageOS on older Android phones with the purpose of using one of them full-time. It's going well. Had to give up less than I feared, but tap-to-pay is likely one thing that will never work without Goog's official shitware.

@dinofp have you tried an app called Curve? I seen it mentioned in Murena /e/OS blog for contactless payment.
