Nokia is never an option, because they do not open the bootloader on any phone. Worse, in the beginning they lied they would, to get people to buy their crap. Also, don't be blinded by their brand, that brand is actually chinese HMD now, with the chinese attitude to running random closed binaries on your phone. So if you go down that route, better get a properly supported phone, like from OnePlus.
