Hello
@HalfpipMarathon,
I have a Samsung A5, now frozen at Android version 8 andan A51, android version 12. Both are incompatible with the Dexcom One app and neither will progress beyond telling me that each is incompatible.
Out of curiosity I installed the Dexcom Clarity app on my younger A51, which initially indicated it was incompatible with Clarity, but then (behind the scenes) proceeded to install it anyway and made the association with my original registration with Dexcom and adopted the data from that registration onto the Clarity profile app. So now I can see the potential of the Clarity app, but because I don't yet have a sensor I can't see any data. But I wonder if you were able to install the Clarity app onto your phone, would that then see the data from your Reader? Worth a try, perhaps?
