Good to see that we think alike.
Nokia has some really creative features in their phones. Like, having a high sensitivity touch screen so you can actually use the phone WHILE WEARING GLOVES IN WINTER is amazing.
Yeah, I love the stuff that Nokia has been doing since their WP rebirth. Especially in the camera area. Sony is responding now with very high quality cameras in their phones with a lot of features. They are one of the few companies (Samsung being another) that has the dedicated digital camera chops to really be competitive using their own hardware.
Nokia is putting a lot of new, useful features and apps in a bunch of areas, though, not just cameras. I feel that they are becoming what Apple used to be. I hate to say Apple isn't innovating anymore, since it has become just an easy and common thing to parrot, but it's true for the most part, except for their camera features. That can change if they release the smartwatch they are working on and its as good as I suspect it will be. The last time I was this interested in a new product category and release from Apple was the iPad, and that turned out to be golden (not literally like the new iPhone 5S).
LG seems to be improving build quality, but they can't seem to move away from glossy plastic. Their internals are pretty damn competitive now, though. I'd gladly take the G2 over the S4 or Note 3, but that's probably personal preference.
Samsung doesn't seem to be trying anymore with design, I think they just jam in the top specs they can with the optimum profit margin attached, and call it a day. They can do it, too, because they have the software customizations as a "value add" (quotation marks because value is dependent on your own opinions) and their vertical integration means they don't have to worry about supply or pricing issues too much. They still make really good phones like the Galaxy Note line, but it seems to be mostly iterative improvements dependent on newer hardware. Which is why they just keep upping the numbers on their existing products, Galaxy S _ and Note _. Which is fine, but they are falling into the same pattern or cadence as Apple. But Samsung does make the widest spectrum of devices, so there's bound to be a product everyone likes.
Everything in the middle can be good or just good enough depending on phone model and price. HTC would be on top with the One - which is absolutely my favorite mobile device, period - if not for the early production problems with the One. Mine doesn't have any issues, though.
