Samsung has set its strategy pretty clear in the smartphone market. They have dozens of models running the already so popular OS Android, in all varieties and for all budgets. Covering so much of the market demand, they have managed to be the number 1 in sales in Q3 and now have huge expectations for Q4 also.
According to the financial analysis from UBS Samsung will sell around 61.6 million units in Q$, the last quarter of 2012. There's hasn't been a manufacturer to ship so many smartphones in a quarter ever before, but Samsung is heading for the record. They are somehow backed up by the fact that in Q3 only they sold 57m smartphones, and with the holidays coming they should be in the books in Q4.
Samsung's flagship devices, the Galaxy S3 and Galaxy Note 2 are supposed to be the center of attention in Q4. Other less popular devices are not expected to make such a big difference in the sales numbers.
