On Tuesday, plugged-in market research company, TrendForce, released its smartphone estimates that showed numbers that weren't good for Apple. Newly released estimates suggested that Samsung smartphone sales surpassed Apple's iPhone sales for this year's second quarter.

The firm stated that the report on Apple's sales contributed to the decline of its global market stock to 12.1%. This figure marked 30% sequential decline. TrendForce further noted that if the new iPhone 5s was not launched until the first week of October, Apple's numbers would get worse.

On the other hand, Apple's rival, Samsung, was estimated to sell 71 million smartphones into channels. This would help explain the company's US$8.3 billion revenue for the quarter.

TrendForce said that Galaxy S4 shipments amounted to 23 million units in the second quarter. The figure suggested that Samsung's android smartphone was not only the fastest-selling device but also the best-selling smartphone in the world. TrendForce noted that Apple was behind one million sales from Samsung.
