Samsung have announced that they have shipped 20 million of their Galaxy S4 smartphones, making it 1.7x more popular than the last-generation Samsung Galaxy S3 over the same period of its lifetime as the company's top-tier phone.
Selling 10 million in its first month on sale alone, Samsung are now stating that the Galaxy S4 is on track to become their first 100million unit selling smartphone.
However, it's not clear whether Samsung are counting this figure as sales through its channel to retailers, or those in the hands of customers. It's possible that Samsung are including devices sitting waiting for an owner in warehouses. Regardless, the company are still getting them out of the factory and on their way to stores more quickly than the previous generation.
If the vanilla Galaxy S4 isn't your thing, Samsung have been churning out Android handsets of various specifications bearing the branding; take a look at the Galaxy S4 Mini, the Galaxy S4 Zoom and the Galaxy S4 Active, to name but a few.
