Your post and thought process assumes that the world of Cellular phones and mobile technology exists in a Vacuum. I can assure you, it doesn’t.
You also assume that I fully side with Apple in the point of this tread (the lawsuit) I don’t. I see viewpoints on both sides as being valid. I do feel that some of the design aspects of the early phones are shockingly close to Apples first iPhone. Why not mimic the other Korean company that was shipping first, LG?
Apple has been working with Graphical user interfaces since before 1984, after a questionable interaction with Xerox from which Jobs got the idea. As hardware improved on computers, the OSs running on them gained more features over time. The same has happened on Smartphones, including ones running iOS. As hardware and batteries have advanced, Apple has brought over more of the features from OS X to improve the devices, including (but not limited to);
- Cut copy paste
- Multitasking
- Configurable wallpapers
- Widgets
- Base applications
- Bluetooth connectivity
In addition to that, Both Android and iOS have roots in Open source, and those communities have contributed to introducing new mobile software features over time. In fact, that community introduced many functions to early jailbroken phones before Android was even popular, including control center, some multitasking, widgets, etc.
Moving further away from the vacuum, many of the features on both platforms are actually licensed from 3rd party entities, with some inventions on our devices having come from some random sources that have nothing to do with cell phones. Take a trip into your device’s about page, to see just who invented many of the features on phones and mobile OSs.
On the hardware side, you are ignoring the normal evolution of technology, And how that side of the market works. Apple isn’t copying OLED screens from Samsung, they are buying panels from them. Bezels have been disappearing on Laptops, monitors, TVs, digital picture frames, etc for decades now. We are quickly moving to a world of science fiction where we simply have a surface where the technology itself is invisiable.
As an aside
The S-Pen you brought up, is an Active Pen who’s technology was invented by, and licensed to Samsung by Wacom. It is Wacom (and a few other patent holders) that deserve credit for Apple Pencil, not Samsung. In fact, Samsung has invested in Wacom to further it’s ties to some of their technologies.
