According to phone arena the Z4 Compact will be launched on the 13th. The question is.... Is it a new design or just a mini Z4 hardware wise? And will it be an international device or Japan only? http://www.phonearena.com/news/Sony-Xperia-Z4-Compact-to-be-unveiled-on-May-13th_id69022 While most "mini" versions of flagship phones are smaller in size with less impressive specs, Sony has taken a much different tact with its "Compact" line. The Sony Xperia Zx Compact models are indeed smaller than the full-size versions, but the specs are basically the same. Occasionally the smaller phones provide the better mobile experience. For example, users said that the 4.3-inch, 720p screen on the Sony Xperia Z1 Compact was better than the 5-inch 1080p display on the full-sized model. What brings this up is a report out of Russia that gives us a possible unveiling date for the Sony Xperia Z4 Compact. Before we give you that date, we do want to mention that a leaked image reveals that the Xperia Z4 Compact will have a model number of SO-04G. The Sony Xperia Z4, which is reportedly being sold only in Japan (another model will be offered globally), was officially announced last month with a model number of SO-03G/SOV31. Now that this is all clear, we can tell you to expect the Sony Xperia Z4 Compact to be introduced on May 13th. That happens to be exactly one week from today, so circle your calendar and keep your schedule open for next Wednesday.
