According to the Chinese social networking Digi-Wo, Sony announced on November 12 the world launch of the smartphone Xperia Z1S also known as Xperia Mini Z1 and present in Japan as Xperia Z1f. The event will be held in Shanghai.
The announcement was published as a graphic containing the slogan "Be moved", which quite clearly suggests that they are indeed talking about a mobile device. Although it is not clearly stated what device is discussed, it is almost certain that we are talking about the global version of Xperia Mini Z1. Another possible candidate for the event is the rumoured Sony Xperia Tianchi, a 6-inch phablet with a 720p display and an octa-core MediaTek processor. In the next few days we should see more details on the conference and equipment that will be presented there.
