ZTE is already linked to a device called the Axon 10s Pro based on the Snapdragon 865 SoC and the 5G X55 modem. Now, it appears the Axon 11 is also on the way. This one is no flagship, however: it is more likely to offer the mid-range 765 (or possibly 765G) chipset, which still gives it next-gen connectivity.
