The latest rumored specs for the Sony Xperia Z4 include two different variations of the phone. A model carrying a 5.2-inch screen with resolution of 1440 x 2560 features a pixel density of 565ppi. Another model with a 5.2-inch 1080 x 1920 resolution screen offers a pixel density of 424ppi. Both models are equipped with a 64-bit octa-core 2GHz Snapdragon 810 processor. In the states, the device will come with 4GB of RAM; in Europe and Asia, the phone will feature 3GB of the stuff. A 20.7MP snapper adorns the back of the handset, while a 5MP "selfie" camera will be found in the front. The 3400mAh battery will keep the lights on, and Android 5.0 will be pre-installed. IP68 certification means that the phone can survive contact with dust and water. The device will be offered in white, black, blue and silver.
If we knew for sure that this mystery phone was the Sony Xperia Z4, we could say that the FCC and Japanese Ministry certifications would make it appear that the unveiling of this device is coming soon. Unfortunately, the evidence is not very compelling. The phone that visited the FCC had a firmware version of 25.0.A.0.33. The firmware version for the Sony Xperia Z3's Lollipop update should be 23.1.X.X.XXX. But that is not enough proof to go on. The mystery device carries a Type Number of PM-0850-BV and an FCC ID of PY7-PM0850.
While the Sony Xperia Z4 was conspicuous by its absence at CES, it should be a welcome visitor at MWC in March.
