There have been reports to suggest that LG could be rebranding its G-series flagship handsets, and so it has been speculated that the “Icon” moniker could be an indication of that happening. At this point in time it is unclear as to what kind of specs/features we can expect from the phone or smartphone, so we’ll have to wait and see.

It is possible that we might not even find out about it at MWC 2018 which takes place in February. According to a recent report, it was revealed that LG’s flagship smartphone could be launched in March instead, but since nothing is official yet it’s probably best to take it with a grain of salt.
In the meantime LG has confirmed that they will no longer be releasing flagship smartphones on an annual basis, and will only launch new handsets “when it is needed”. It will be a pity as LG does make some pretty decent handsets.
