GrapheneOS only supports the google "pixel" line of phones (probably because they support the bootloader-locking by user, and ship with most stock android/AOSP support): https://grapheneos.org/faq#supported-devices https://grapheneos.org/faq#supported-devices I'm running it on a pixel-4a (google-sunfish) and it works fine. You may want to pay close attention to the parts where it tells you how to lock/unlock the bootloader: https://grapheneos.org/install/cli#enabling-oem-unlocking https://grapheneos.org/install/cli#enabling-oem-unlocking https://grapheneos.org/install/cli#disabling-oem-unlocking https://grapheneos.org/install/cli#disabling-oem-unlocking CalyxOS also supports older models like the pixel 3, albeit with lower standards for security: https://calyxos.org/install/ https://calyxos.org/install/ Additionally there's AOSP distros like LineageOS that support many devices, but with much lower security standards: https://wiki.lineageos.org/devices/ https://wiki.lineageos.org/devices/
