LG has finally revealed its hand. Save for HTC and Motorola, we pretty much have the lineup of flagship smartphones for the first half of the year. For some, it may even be the only flagship for 2018. With many of them bearing mostly the same basic specs, how do these premium, and sometimes expensive smartphones stack up against each other. We take a look a the Samsung Galaxy S9+, the Huawei P20 Pro, the Sony Xperia XZ2 Premium, and the LG G7 ThinQ and size them up for this year's battle.
