The Sony Xperia Z4 was expected to make it debut earlier this year during CES 2015 in Las Vegas, however, the much anticipated follow up to the Xperia Z3 was a no show. Be that as it may, we have new rumours pointing to the device launching a lot sooner than expected.
The upcoming Sony flagship was seen making the rounds through certification over at the American Federal Communications Commission (FCC) and the Japanese Ministry of Internal Affairs and Communications. According to the certification leaks, there are currently three variants of the device making the rounds. The three variants are apparently headed for Japanese soil. The three variants are PM-0793-BV (for NTT DoCoMo), PM-0792-BV (for au/KIDDI) and PM-0794-BV (for SoftBank). The certifications reveal little else about the device aside from LTE connectivity on bands 2, 5, and 7 as well as the firmware version (25.0.A.0.33) which is higher than the upcoming Lollipop release headed for the Xperia Z3 with the build number format 23.1.X.X.XXX. While all of these could point to the Xperia Z4, there is little concrete evidence pointing to this.
In addition, leaks of the front panel of the Xperia Z4 have surfaced showing some familiar things and some changes being made. First up, the dual front-facing speakers are staying on the Xperia Z4, following its predecessor’s design language. In addition, it looks like the front facing camera and sensors have swapped positions – the camera moving to the left while the sensors to the right – the total opposite of that seen in the Z2 and Z3. The top and bottom bezels, which have been highly criticised, are making a comeback.
Other than that there is not much to go by when it comes to information on the Xperia Z4. Previous leaks point to the upcoming flagship coming with a 5.2-inch display with Full HD 1080p resolution, while the processor will either be a Qualcomm Snapdragon 805 or a Qualcomm Snapdragon 810. It will also be running on 3 GB of RAM, and will have a brand new camera sensor.
We also have new leaks which point to the Xperia Z4 getting a Dual SIM variant for select markets. However, aside from the screenshots of the UI, there is very little in the way of specification confirmation. The only specification that is confirmed is the processor being the Qualcomm Snapdragon 810 thanks to the screenshot of the About Device page which lists the chipset as MSM8994. In addition, we have a glimpse of what Android 5.0.2 Lollipop will look like with Sony’s Xperia UI. Sony has integrated a lot of Google’s Material Design throughout as seen in the screen caps.
