Samsung has launched over 100 Android phone models, without counting variations of each (but it seems tablets that can do voice are also counted).
That site re-counted some models across carriers, but that still leaves about 90.
Apple's had 13 models since the beginning (although they looked similar on the outside, they had different radios).
However, Apple didn't have any CDMA models for several years, and they were also a year late with LTE. Otherwise they'd have had about 20.
Samsung also designs models for every price range. Apple simply sells older models at lower prices, instead. If Apple had hit the lower and middle markets, they'd have had about 60 models.
Finally, Samsung updates their phones more often, and includes some niche units with keyboards, and so forth. That pretty much accounts for the rest.
Trimming down that product line would probably result in even better products that benefit from more resources, more R&D, and time committed to a more concise product line.
I was thinking the other way... that Apple could learn from Samsung's ability to manufacture so many different models.
Cook is supposed to be good what he does, but he only has to deal with a handful of models each year. Yet he even goofed up the planning for that few (when Apple made too many of the wrong model on the 5C debut) and also blew the iPhone 5 production quality at first. (Remember Foxconn going on strike over the manufacturing demands?
