Though it doesn't seam so bad but Samsung was hoping for better sales as they had projected to sell 70 million units in 1 year.
With the sales not as high as expected, Samsung is now wondering if they should release the Note 5 in July or wait till September which will about the same time as the new iPhone 6S.
If they release the Note 5 in July it will affect the sales of the Galaxy S6.
I believe Samsung could have sold more units of Galaxy S6 if they had not released 2 models. Releasing 2 models confused the market. Samsung also plans to release the "Iron Man" edition of Galaxy S6 Edge this week. I wonder if this will be a good move on Samsung's part which may hurt their sales further.
