One new model LMV600L was found in LG database and info from LG is shown below (left):
As we can see in the screenshot, this model is manufactured on May. 29, 2020 that is much later than that of test model LMV600N which is manufactured at Sep. 16, 2019. So far, we have not got any other rumors about LMV600L and it’s still uncertain if LG will release V60 ThinQ 5G in South Korea market or not.
