So I have Aurora in my main profile that allows apps from play store with no play services installed it just uses the open source aurora store and my bank apps all work without playservices. And I don’t use streaming services in anyway I buy everything on bluray and then rip it to my server. But with private space on android 15 you can install sandboxed play services in private space and it is 100% seperate sandboxed from your main profile and can use apps like Netflix etc that do require sandboxed play services and then when not using it you can pause private space essentially shutting it all down and preventing any of the apps from running in the background at all. Plus with sandboxed play services on GOS you can control all permissions for play services all way down to network so you can only allow network or more just depends on your personal threat level or how comfortable you are sharing the data. But even with sandboxed play services in a main profile would still be more secure as it only installs the play store and play services apps no AI.
So contactless is still broken and that is because it is signed by a certificate granted by Google GOS does not have this cert so contactless is. Broken Unless your bank has thier own implementation then it may work. Also if the app your using comes from the play store you must have sandboxdd play services installed or. Yes you are correct notifications will be broken as it relies on play services for them to work but if you use play services sandboxed everything should work minus any app that enforces play services integrity check…
