I feel durable rugged smartphones are less popular than the iPhone is because people don't want to switch to Google Android smartphone makers which makes phones which can survive drops to the floor.
Some rugged phones may look too tough because of the hard plastic shell, so people who don't want to appear tough may rather pick a more friendly looking phone like the iPhone, and Samsung Galaxy S7.
More durable phones also cost more than a similar phone, and people may want to spend the money on a hard protective case, and glass or plastic screen protector made of durable glass like Gorilla Glass.
Some workplaces like a bank or office may have a dress code where you can't wear casual clothes, and are only allowed to wear suits and business clothes. The work dress code may ban the use of rugged and tough looking smartphones with a very manly appearance because the case looks like a construction tool, or military gear.
