Good point. I hadn't noticed that until now.My X4 on Verizon also shows LTE. That doesn't bother me, since as noted, LTE is by definition 4G.
What does bother me a bit is that unlike my previous phone (a Moto E5 Play), there are no up/down arrow indicators under the LTE legend. It is completely blank.
It was nice to see even attempts to download or upload.
