Apple doesn't utilize the iphone's full capability. It's not the consumers fought. Other phones can do split screen, PIP, VR, convert to a PC, HDMI/mhl support, multitasking, real file manager, mouse/trackpad support, and stylus capabilities and still get stellar ratings and reviews. Apple forces it's fans to support face recognition and AR. Seriously besides the OLED screen and heavily criticized design. This is not that much of a upgrade. In terms of Touch ID, it may be a downgrade.
By not allowing them to do any of what's mentioned above, they will never utilize it's full capabilities since Apple limits the consumer.
Although you're fairly technical with what you're referring too, my point was based on a real experience, the iPhone has an immense amount of power, it's just the average consumer likely doesn't utilize that with social media applications, gaming applications, and or the Forms of media. Even if the average consumer could take advantage of the iPhones full capabilities, I doubt a majority do.
