LG's G5 — as interesting it may be with its modular design and host of accessories — was a flop. Now, the company is trying to redeem itself with a very different flagship phone, and it's likely to launch on Feb. 26, ahead of the Mobile World Congress (MWC) in Barcelona. We know this because we've just received an invite from the company. As is customary, the invite does not contain many details, except the place and the date.
