Hello to the forum,
is there anyone in the forum who canconfirm that the December or January (if available) update of iodéOS passes all the tests of the “Integrity Checker” app (https://play.google.com/store/apps/details?id=gr.nikolasspyr.integritycheck)?
Regards

You need to enable Google SafetyNet in microG settings to enable the Play Integrity Checker to connect to the Google server.
My Shiftphone 6mq with unlocked bootloader only got basic attestation with Play Integrity Checker. I didn’t test it with locked bootloader because I rooted the phone afterwards. After rooting the phone I didn’t get any verification.
