Do you mean that you would like to know why we are no longer carrying the LG G4?
Our products and services change often and without advanced notice. As much as we would like to, notifying our customers that certain devices are going to be discontinued soon is not something that we're able to do.
Over time, older devices are removed from our lineup to make room for the newer devices that we are carrying.
Even if a device has been discontinued, it may still be possible to find that device in a store, however, that's not something we're able to guarantee as it depends on the remaining stock available.
