[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] FunkyRasta:
Thanks for the log. There seems to be some errors regarding Tap&Pay indeed. I tried using my own bank's app for NFC payment instead of GPay, but the result is the same. I do not know much about Android tap&pay architecture but this bit seems important . Any other devices users are reporting problem with Gpay on AOSP Android 10 ROMs? If yes then it is not our device tree fault at all.
