Users are buying normal mobile phones with added features rather than smartphones because they can't distinguish the two, say analysts.

Smartphone sales in Western Europe were up ten percent between April and June this year, said IDC analyst Andy Brown, but he had expected better considering the more mature normal phone still managed seven percent.

"Feature phones are 'good enough' for most users," he said, adding that users apparently prefer camera and multi-media functions, to the more advanced and expensive data-based functions on smartphones. Delayed smartphone launches may have also affected sales, said fellow IDC analyst Geoff Blaber.

Overall, Nokia continues to dominate the market in Europe with its phones accounting for 74 percent of total phone shipments in the region in the quarter.

Nokia also grew its percentage of total Symbian-based phones sold in the quarter, a potentially troubling sign, Brown said. In the second quarter, 98 percent of Symbian phones came from Nokia, compared to 89 percent in the same quarter last year.

Gartner also released results of its analysis of the mobile phone market for the second quarter on Thursday. Both research groups found that while Nokia grew its market share and holds onto its first-place position, Motorola has made significant in-roads.

Worldwide, Motorola has gained 4.2 percent of the market in the past year, reaching 21.9 percent. Nokia gained 2 points to 33.6 market share worldwide.

Both research groups also found that Samsung is struggling. The company lost nearly two percent worldwide market share but still holds on to the number three spot, with 11 percent of the market. Worldwide mobile phone sales reached 229 million during the quarter, an 18.3 percent increase over the same period last year, according to Gartner.
