This one is definitely the hardest and is the least mature. Have you managed to get off Google on your phone?
I’m using GrapheneOS (Degoogle’d android) on a Pixel 6a. The irony isn’t lost on me that I had to buy google to get off google.
I had tried Pinephone and Plasma mobile, but it still needs more work and I needed a phone sooner as my old one was failing.
How about you? Did you manage to get away from Google?
My banking app worked for me on both Calyx and Grpahene no problem
