Samsung said it will have a phone for Verizon, AT&T and other networks in the first half of the year and at least one more later in 2019. And OnePlus' upcoming 5G device for UK carrier EE will be the first smartphone in Europe to use the new Snapdragon 855 chipset. In August, Motorola revealed that in early 2019 it will release a 5G "Mod," or module, that attaches to the back of the Moto Z3. The Mod will let it run on Verizon's 5G network.

By the 2019 holidays, every Android company working with Qualcomm on a phone for the US market will launch a flagship that has 5G, Qualcomm president Cristiano Amon told CNET. "Every Android vendor is working on 5G right now," he predicted.
