IMO, the market and trends dictate what companies do. In some sort of complex equation (that I don't understand), companies such as Apple, Samsung, Google, Huawei, etc. are jumping on the bezeless design and loaded-to-the-hilt with features smartphones.
Its like Apple took a page from Samsung and created a PRO version to rival the Note line.
So now we have flagships in 2 sizes, and then ultra-high end devices. Its nothing new, but since Apple is doing it, the iPhone X is ironically something to talk about.
LG - V30
Huawei - Mate 10 Pro
Samsung - Note 8
One Plus - OP5T
These companies know many (not all) people are willing to pay top dollar for the "best" smartphone. Instead of adding features into their flagship phones, companies reserve the very best for their ultra high end devices. Sprinkle in a new feature or two on the flagship and bump the price just a little.
Its funny because I'm sure we are paying for the "cost" of removing a headphone jack.
