Samsung's growth in the smartphone and tablet arena is both impressive but commendable. But the company is still short of Apple's sales numbers. Apple has posted a first weekend sales report of 9 million units for iPhone 5S and 5C.

Besides, analysts and experts are extremely upbeat about the upcoming iPhone 6 to break sales records. Here is a report on the feat achieved by Galaxy S5 and a report on the expected sales from the upcoming iPhone 6.

Samsung Galaxy S5's Feat

Within 25 days of its arrival, Samsung Galaxy S5 has shipped a whopping 10 million units worldwide, according to sources from South Korea (via GSM Arena). This feat confirmed that Galaxy S5 has outperformed Galaxy S4 in 2013 by two days. Also, Galaxy S5 can also boast another record for the opening day sales in many parts of the world.

Samsung Galaxy S4 managed 10 million shipped units in 27 days, whereas Galaxy S3 reached the same target in 50 days of its arrival. Galaxy S2, on the other hand, shipped 10 million units in 5 months and Galaxy S did the same in 10 months of its arrival.

Apple iPhone 6's Expected Growth

The upcoming iPhone 6 and iPhone phablet are two of the highly anticipated devices this year. This is the first time Apple is bringing in the relatively larger display for its flagship devices. According to reports, iPhone 6 will feature a bigger 4.7-inch screen and the upcoming phablet from Apple is expected to house a whopping 5.5-inch display.

Katy Huberty, an Apple analyst at Morgan Stanley, said the expected sales of Apple's new iPhone 6 would climb 20 percent when compared to the sales of iPhone 5S, as launched in 2013. The impressive first-quarter iPhone sales growth, in addition to the strong iPhone sales growth from last quarter could give investors the much-required optimism for this year.

With the bigger screen size and the amplified optimism, Apple might beat the expectations of fans and investors alike.
