Our requirements are for industry standard privacy/security patches and protections. We haven't set a high bar but rather have very reasonable requirements. There's nothing puritanical about requiring what we do for a privacy and security project.

Most people don't have a device permitting using another OS at all or without crippling functionality including security. They need to buy a device to use another OS as a production quality daily driver. The vast majority of GrapheneOS users bought devices to use GrapheneOS rather than using GrapheneOS because it was available for a device they bought without considering it.

We don't want people to buy devices which will stop getting privacy/security patches for the firmware, kernel, drivers and HALs after 2-3 years and are missing important security protections. If we support a device then people are going to buy it to use GrapheneOS. Few of the people who end up using it are going to be people who already had it.

We don't want to have a watered down form of GrapheneOS without the core protections including what we build with hardware memory tagging. Older devices which we discourage buying not providing all the current requirements is much different from adding new devices without those. Our recommended devices (Pixel 8 and later) provide all of the current requirements and we strongly discourage buying older devices without enough support time remaining or the current protections.

We have a serious OEM partnership because we stand by our requirements and haven't watered down GrapheneOS. An OEM working with us to improve their devices to meet our requirements and helping port GrapheneOS to those with full functionality is only possible because we don't poorly support anything able to run another OS.

GrapheneOS is open source and others are free to make incomplete ports to other devices under a different name. Many individuals and companies have done this and it hasn't gained any significant interested. It doesn't provide what GrapheneOS does and the expectations of our audience are much higher. Our audience doesn't want a device with 2-3 years of delayed security patches for the firmware, kernel, drivers and HALs follow by end-of-life.

An end-of-life Xiaomi device with no privacy or security patches for the firmware, Linux kernel, drivers and HALs for years doesn't provide the bare minimum for protecting user privacy and security.

It would theoretically be possible to port it to a newer kernel but that's not within the scope of LineageOS. It doesn't do that so there aren't Linux kernel updates since the kernel branch has been end-of-life for years already. It would also theoretically be possible to rewrite all the userspace drivers and HALs, but it's not being done. The firmware is a different story since it's usually signed and requires vendor support. It's important too since it's exposed to remote attacks via cellular, Wi-Fi, Bluetooth, NFC, GPU (web browsers, etc.) and more.

Yes, currently Pixels are the only phones with support for the hardware security features GrapheneOS requires.

In 2027, you will be able to use the Motorola flagships to run GrapheneOS.

Grapheneos is still based on Android.

The vast majority of smartphones don't allow installing another OS. Multiple Android OEMs have been restricting or fully phasing out supporting it. Among devices which do permit it, none have provided the hardware-based security features or driver/firmware update support needed by GrapheneOS beyond Pixels. Our hardware requirements are listed here: https://grapheneos.org/faq#future-devices

GrapheneOS has an official OEM partnership with Motorola Mobility and a subset of their next generation devices will be provided official support for GrapheneOS. They'll be providing us with a more minimal form of hardware support code close to the standard Qualcomm and other vendor code, so it will be cleaner than Pixels. Our partnership with Motorola is non-exclusive so we're free to support other devices with the help of other OEMs interested in meeting our requirements, but no other OEM is working with us yet.

We can't use devices with an end-of-life Linux kernel, no firmware updates, no driver/HAL updates and no support for important hardware-based security features we use. Several devices of a lot of the way towards providing what we need and several next generation Motorola devices will provide it. Other OEMs can do the same.

You can't trust Google not to pull the rug. That's a big part of the reason GrapheneOS now has a deal with Motorola for the next generation of devices.

they are already pulling the rug. Google took months to publish devicetrees for the Pixel 10. they've signaled (iirc) that they'll no longer make the Pixel line capable of running AOSP. the reason they even did at first was to make Pixel a reference implementation that vendors could use to port Android, but now they've announced a switch to an emulated device for that purpose.

Don’t defeat yourself in a one person battle.

After all, it might rain tomorrow - but you should still go outside today.
