South Korean electronics giant Samsung on Friday reported quarterly earnings that failed to match analysts' estimates, dropping another hint that high-end smartphone market has saturated.

Samsung announced that its net income jumped 50 per cent year-on-year to 7.58 trillion won ($6.8 billion) in the April to June quarter this year, from 5.05 trillion won in the corresponding quarter of the previous year.

A group 24 analysts surveyed by Bloomberg had projected an average net income 8.02 trillion won for the company's quarter under review.

However, the company's total sales jumped to 57.5 trillion won, slightly more than the company's own preliminary estimate of 57 trillion won.

Operating profit soared to 9.53 trillion won, again slightly more than the company's own project of 9.5 trillion won but lower than analysts' average projection of 9.99 trillion won.

Commenting on the figures, Seoul-based analyst Lee Jae Yun said, "The mobile business, the company's biggest bread earner, has already peaked out in the first quarter. That is increasing uncertainty over the company's overall profit growth next year."

But, Samsung said that it expected smartphone market's strong growth streak to continue in the current quarter, though at a slower pace.

After the announcement of the quarterly results, Samsung shares slipped 0.7 per cent to 1,306,000 won in Seoul.
