The reputation of Nick Calyx (worth a look his Wikipedia page), or GrapheneOS team, etc, is so much easier lost than that of, say, Google's Android team.....or iOS security team.
Having said that: Calyx shouldn't be considered much more secure than Android Open Source Project (AOSP). That's where GrapheneOS shines.
Calyx should, however, be considered more private than AOSP, less dodgy & exploitable than Samsung etc Android "enhancements", aka UI/UX bloatware.
