Now that Asus of small phones are dead, and Sony not bringing the Xperia 5 over to the states, there really are only three players left in the small phone field 😞
Actually Android smartphone companies were the ones that pushed the industry towards bigger phones in the first place. Apple started making big phones starting with the iPhone 6 to compete with them. Apple didn't want to make bigger phones, but they had to because that's what everyone else was doing.
