Samsung S9+ G965W support?

Those phones can’t be supported due to technical limitations which are there because of the already mentioned different chipset. Some NA users bought the EU version of the devices. There’s also a number of supported chinese phones which you should be able to get. Or the FairPhone if it’s sold in the states. Using the search function of this forum should get you some threads with interesting informations.
