> 2. I don't have Google Photos and the pixel camera app tries to launch google photos when you want to review the picture you just took. But there is a FOSS app called GPhotosShim that uses the same namespace as google photos and thus fools the camera into launching that app instead. Once launched, it just launches whatever media management app you actually have configured, so it's seamless.

There's also GCam https://github.com/lukaspieper/Gcam-Services-Provider

I don't know if it matters, but GPhotosShim doesn't seem to get updated.
