An Android version of QQ International was released on September 2013.The client's interface is in English, French, Spanish, German, Korean, Japanese and Traditional Chinese.Most of these clients are cross-platform, so they are usable on operating systems which the official client does not support.However, these implementations had only a subset of functions of the official client and therefore were limited in features.QQ was first released as a "network paging" real-time communications service.Other features were later added, such as chatrooms, games, personal avatars (similar to "Meego" in MSN), online storage, and Internet dating services.Furthermore, QQ's parent company, Tencent, has over successive versions modified the QQ protocol to the extent that it can no longer be supported by most, and perhaps any, of the third-party implementations that were successful in the past (some of which are listed below).As of 2009, none of the developers of third-party clients have publicized any plans to restore QQ support.
Rather than solely a web-based IM, Web QQ 3.0 functions more like its own operating system, with a desktop in which web applications can be added.
The live translation feature is available for all incoming messages and supports up to 18 languages.
QQ International for i Phone and i OS devices was released at the end of 2013, to bring the QQ Casual Gaming portal as well as the QQ Messenger as an addition to the already thriving Vietnamese gaming communities.
Tencent's social network Qzone is linked to in the International and native versions of QQ.
Using reverse engineering, open source communities have come to understand the QQ protocol better and have attempted to implement client core libraries compatible with more user-friendly clients, free of advertisements.
