China consumers' association has expressed support for a non-profit lawsuit filed by Shanghai Consumer Council on June 2.

Shanghai Consumer Council filed a public interest litigation against Tianjin Samsung Electronics Co. and Guangdong Oppo Electronics Industry Co. on June 1 for infringement of consumers' rights including pre-installing excessive numbers of apps.

The result of comparison tests shows Oppo X9007 and Samsung SM-N9008S rank the first and second respectively among phone models which have the highest number of preinstalled apps that cannot be uninstalled.

The council said mobile producers should inform consumers of the functions and storage space the pre-installed apps have taken.

It also hopes to break the hidden rules of the mobile phone market including bundle sales of apps and phones without acknowledging consumers along with promoting fair competition in the industry.

A court in Shanghai has received the case which is the first of its kind in the Chinese mainland.
