Phones are big now because people want better cameras and longer battery life. Also, people are spending 4-5 hours more per day on screens than they did 15 years ago, so they want bigger screen for reading, playing games and watching videos.
Again, I’m not angry that current phones exist; I’m just sad there aren’t (good) alternatives – at least that I know of.
