    Disable 2g by default ??? Profit?

    I’m not sure what’s so hard about this, I get that 2g goes further for emergencies but it’s basically useless for anything else, have it be enabled if needed (and communicate that with users when first disabling it)

    Google Apple and Samsung are all working on / have satellite SOS, which should replace the long term need here

    Never going to be enough, use a VPN, and only use end to end encryption for calls…

    Or use a VOIP service like google voice for the calls, at least force your monitors to get a warrant to google, make them do some leg work

      Even that isn’t enough. The wireless modules of normal phones have direct access to system memory and, by law, have proprietary firmware. Some exploits have been found over the years. This needs to be isolated to avoid backdoors/bugs.

          Example: https://grapheneos.org/faq#baseband-isolation

          Yes, the baseband is isolated on all of the officially supported devices. Memory access is partitioned by the IOMMU and limited to internal memory and memory shared by the driver implementations…Earlier generation devices we used to support prior to Pixels had Wi-Fi + Bluetooth implemented on a separate SoC. This was not properly contained by the stock OS and we put substantial work into addressing that problem.

          Baseband modems were not isolated from kernel memory in stock Android, GrapheneOS had to do it themselves using the IOMMU. We do not know for sure due to the proprietary/closed-source nature of baseband modem drivers, but we have no reason to assume any OEM (Samsung, Xiaomi etc) implemented proper isolation of baseband modem and system memory.
