Not much. Generally speaking the evolution of phones has largely peaked on the bell curve. People in this house have several generation back phones and haven't even bothered asking for upgrades. They are fast enough to run any app. Have great cameras. Plenty of storage space, etc. Prior to that, everyone wanted to upgrade every year.
I remember speaking with a top phone engineer sometime around 2000. He said they have a 20 year plan for phones, phone evolution and feature creep. He gave me a pretty good idea of where they were going and surprisingly, they had a really really good idea of where the size and processing power would end up. So the inevitable question came up - what about after 20 years? At the time he didn't have an answer.
Just a few years ago everyone talked about their phones. People would get new ones and show them off. Now nobody cares. Nobody talks about them. Nobody really even bothers to look at each others phones or show them off. Has anyone else noticed this? I think the reason is, people know it's capped out and by this stage everyone has a reasonably comparable from regardless of what manufacturer or cell phone.
5G is really all they have left and between people worried about the dangers of it, and the prosumers who feel it is unnecessary because they know the increased speed on a phone is largely placebo, and somewhere in the middle are engineers who feel it isn't viable for widespread deployment due to technical limitations.. I think 5G is all marketing fluff and will fall flat.
Honestly, I don't think we'll see much of anything from them and the industry has plateaued. All anyone I talk to cares about now is how to lower their bill and who has the cheapest plan...
