This is so underrated as a comment, but so true. Samsung just kept at it with incremental updates to a single series and an occasional separate model if they wanted to try something new.

LG was constantly shifting markets. I had a G2 and really liked it. I would have bought other devices from them, but the things that appealed to me about the G2 disappeared in most future products.

Constant shifts in focus gained share but also lost share at the same time. They really needed a cohesive line.
