after 8 years, my Samsung S5 Duos is not only heavily blemished, but also a bit too slow for browsing, even with the much lighter LineageOS with microG.
I'm not a heavy app user, and my main aim is to not need google (or apple) on my phone, a good camera, install my favorite apps from F-Droid, and have the phone for as long as possible - all the while trying to get an as secure phone as possible for my use-case.
My LineageOS 18.1 with microG and unlocked bootloader can pass SafetyNet attestation, and only one app doesn't work: payconiq (which is quite popular where I live). I don't have magisk, rooted, or anything else in that direction.
In this forum, I only found one entry about payconiq (December 2022) which indicated that it didn't work, but that might have been due to the problem which is described in this post, and thus might have been solved.
Could anybody confirm whether payconiq works with GrapheneOS? And maybe if you have experience with other (banking, or identity) apps which work/don't work, that would also be interesting to know.
