Google Camera on GrapheneOS on my Pixel 5 doesn't work very well. I can take several quick pictures, then about after picture six, it starts taking several seconds per picture (the picture-taking-button grays-out and does not do anything).

This seems likely to be hardware limitation rather than software? Assuming the phone works anything like the DSLRs I've had experience with do. Photos get sent to a fast buffer when taken and then written to the slower memory in the background - initially you can take photos as fast as the buffer will accept them, but once it's full you're limited by the write speed of the main storage.

This isn't unique to GOS. I've had this issue with Google Android Pixels for years, and owned the 3, 3a, 4a, 5, and 6a now.

It's _always_ been an annoyance of mine and is definitely not exclusive to just my latest phone.
