Maybe now only Samsung contributes to upstream Android project significantly, and makes advanced device. For example, Desktop Mode code is came from DeX IIRC, WearOS is finally merged to Samsung's OS, foldable phones and customizes are from Galaxy. Samsung is also a one of the biggest conglomerate that has own fab and makes SoC, display, battery, DRAM, NAND, etc... Possibly also Huawei contributed much but it was gone. I think Sony, OnePlus, Asus makes just good smartphones for consumer, but not contributed to advance futuristic Android ecosystem much now (Perhaps Sony Ericsson was big in early days). I'd like to see AOSP commit ranking by organization.
