When is the update expected?
It has nothing to do with Rogers, LG is responsible and they are way behind. I am not sure if it available anywhere else other than South Korea.
I spoke with LG support and I was told they will probably release firmware sometime in Mid of June or before. Still way behind, but get ready for more worst.
Easiest way, simply don't buy LG products in Future, they are expensive and can't be compared with any other Flagship smartphones.
This will automatically reduce there price and strategies.
