But in bounding after large screens, phone makers seemed to ignore the usability issues that accompany them. Small studies have shown before that 4.3 inches is about as big as a phone can get before people start struggling to use it. The time to operate the phone slows down significantly because one-hand use is awkward – and that’s for average men’s hands. Assuming a normal distribution, for half of men and most women, a phone bigger than 4.3 inches – like the current smallest iPhone – is too big.
The increasing size of smartphones is one of the big mysteries of the technology world. The mystery lies not in phones getting larger – a lot of people prefer it – but in smaller phones, which a lot of people also prefer, disappearing, or being treated as second-class citizens.
Such an odd development.
