This news is hard to believe based on the trend we have been seeing. According to ZDNet Korea, although LG is committed to using metal in their flagship smartphones, they might not be ready to make that move with the G4 even though it was previously reported that they would.
According to their sources, LG wants to manufacture their own metal cases, which is obviously a huge undertaking since it would require space, new equipment, and planning. The G4 is likely to be announced in May or June, and that is too close to get anything done.
Now if there is any good news out of this, it appears the G4 Note will sport metal since that is due out later this year.
Will this effect your decision on buying the G4? I personally don’t think metal is the be all end all as long as the quality is there. The G3 was made of plastic, but it had a metal feel and I was personally happy with it. However, with all the press that metal is getting these days, the perception of not having metal on the G4 could be very bad. I guess we will have to wait and see how this pans out.
