As for the record-beating part, the Galaxy S4 racked up 10 million shipments in 27 days, which formed last year's record. While this is a modest achievement, it is still one to admire. And to put things in perspective, the older Galaxy S smartphones - Galaxy S3, S2, and the original S, took 50 days, 5 months, and 7 months each to claim the 10 million figure.
It would be interesting to see whether the company will be able to best the Galaxy S4's 40 million sales. The current tendencies don't spell such an outcome - while the GS4 failed to achieve the GS3's 60 million sales, the high-end smartphone market became saturated, which means less customers are looking to purchase or upgrade to the Galaxy S5.
