A quick comparison with last year's LG G4 shows off the G5's smoother, rounder, and more metallic exterior.
When stacked up against (or on top of) its older sibling, the G5 seems a bit chunkier than the G4. The G4 also felt nicer in the hand, and was a bit easier to grip.
Apparently, LG's move to a modular design and the use of the LM201 aluminum alloy forced them to step back from last year's slightly sleeker form factor. Still, we sense good things in store.
