Hi. I too have found myself asking questions like this when I had phones that had custom ROMs.
tell me what Graphene has stronger?
When I looked into this, I found that Graphene is hardened and is more secure while other ROMs spec into the privacy aspect only.
I still keep my list even though my current device/chipset is not supported by these ROMs.
Alternative/Custom ROMS
In no particular order, these ROMs usually change the UX/UI and maybe add some security enhancements.
-
BlissRoms: Close to stock with “some” added privacy
-
Evolution X: Android 13 with the Pixel UI
-
Paranoid Android: Android with custom enhancements
Privacy|Hardened ROMS
Security-wise, LineageOS is a start but (correct me if I am wrong) you need to unlock the bootloader, which is not great. These ROMs purport heightened privacy or “hardened” security.
-
iodéOS: “deGoogled” LineageOS fork, uses lots of blacklists for ad- and tracker-blocking. Sells pre-installed devices.
-
/e/OS: A “deGoogled” Android experience. Uses microG, no telemetry sent to Google, modified NTP and DNS servers, modified GPS service. Uses the “App Lounge” which combines the Aurora Store with F-Droid and PWAs. Has a tracker blocker. Requires you to have an
@murena.ioaccount for some functionalities. -
GrapheneOS: Private, secure, hardened… has a long list of features. Updates are fast, exploitations are quickly mitigated, non-profit. But, Pixel-only.
-
CalyxOS: PAUSED




So many outlets reporting on this, but there is no story here yet.
The ECHA site has more info.
To me it sounds like they are considering reclassification, at which point decisions can be weighed.
