The dude who wrote that article is a Forbes contributer, not a staff writer. I haven't seen any legit tech sites report that the S6 flopped.
Still the core fact is they shipped 10m, pretty much the same amount as the S4 and S5, which was considered a blip for Samsung...hence why they tried to kick it out the park with the S6.
They clearly hoped to sell more and should be...
Like others have said its too expensive for many, especially with the rise in budget alternatives.
Ima cop when it goes down, great camera and fingerprint sensor is a must this time around for me.
