We are both right 😆
It is true for Signal on Apple devices.
It is not true for Signal on Android devices*
*Well I’m using grapheneOS so I feel more comfortable in my case but a regular Android device with full access Google Play Services? That I’m not so sure about. It’s conceivable that Google has a way to read the final notification (FCM push -> Signal fetches and displays message -> Google can read all notifications on the device, FCM or otherwise) 😬
This is not true for Signal. Other apps may send the notification content but signal uses FCM to push a simple notification to wake the device and tell signal to fetch the actual notification. You can use the full text / info notification and know that Google does not see it.

I’m not a dev, I just use the os. Personally I had issues that prevented me from using it, but they have added great compatibility for Android Auto and for RCS.
To clarify since you’re mincing my words, I said:
Yes grapheneOS increases privacy compared to stock and so do other custom OS, but the key is that grapheneOS does not compromise security but instead increases it compared to stock OS.
Other custom OS lag behind with patches, and grapheneOS is the only custom OS I have heard of where their security patches are actually added back into stock Android.
This is such a soft response and I’ve seen it in a lot of places. People cry and call it shit talking because the devs point out flaws in other operating systems.
/e/, lineage, Jolla/sailfish, they are all bad for security and really not that great for privacy. grapheneOS really is the best without question especially if you value the best security.

I’m not an expert or even close to that, so no, not really I suppose. Can you really trust any device when it comes down to the hardware level? I wouldn’t trust an iPhone or any other phone more. Again, while I’m not an expert, I’d trust grapheneOS for software over any other mobile OS. Probably trust to that effect would be grapheneOS >>>> iOS >> everything else. But full trust in any hardware? Who really knows
