The Consumer electronic products office of the China Electronic Chamber of Commerce recently released its "2008 China Mobile Communications Terminal Product Market Competition Analysis Report", showing CECC has received complaints involving 51 mobile phone brands from January to June 2008.

Of those complaints 99% are within the warranty periods of the respective products, with problems focusing on product quality and after-sales service. Complaints about poor quality of phone calls, operating system crashes and blank screens are among the highest.

According to 315ts.net, Nokia (NOK) received the most complaints at 42%, about 35% higher than Motorola (MOT), who ranked second.

Nokia told the website the figure didn't necessarily mean a high repair rate of Nokia mobile phones. The company currently occupies a 40% market share in China, which means that with so many users, it also received a higher proportion of total complaints.
