Technically all the Sony cameras run on Android. Older models (e.g. the a7 II) allow you to install specially built "PlayMemories" Android apps.
Nowadays Android is mostly a hidden implementation detail, but I did recently see someone Claude+ADB some neat stuff for their Sony camera.
I’m really keen for the future of modded firmwares on cameras. One feature I’d love to have is starting an SMB or ftp server on the camera so I can just copy files over the network rather than having to move sd cards or plug anything in.
So Android is finally back to its root, a camera firmware.
