Sony Unveils New Z3 Series Xperia Smartphones, Tablet, Smart Wearables at IFA 2014Sony Mobile

All eyes are on the Sony Xperia Z4 again after it missed the recently concluded Consumer Electronics Show 2015 (CES 2015), as it is expected to be unveiled at the upcoming Mobile World Conference 2015 (MWC 2015) to be held in Barcelona from 2-5 March.

A mysterious Sony Xperia smartphone, possibly the much-hyped Xperia Z4, has passed through the Federal Communications Commission (FCC) with 'Type Number' PM-0850-BV and 'FCC ID' PY7-PM0850, according to a report by Xperiablog. It went on to claim citing the FCC documents that the device supports LTE Bands 2, 5 and 7. 

The Sony Xperia Z4 was recently certified by the Ministry of Internal Affairs and Communications in Japan, according to a report by Xperiablog (via Blog of Mobile). 

The next-generation smartphone is expected to sport a 5.2-inch 1440 x 2560px Triluminos display, powered by Snapdragon 810 chipset and run on Android 5.0 Lollipop, according to GSMArena. It is also expected to house a 20.7MP camera, 3,400mAh battery and water resistance feature. 

It was earlier reported that Sony would launch two models of the Xperia Z4 - one with a Quad HD display and other with Full HD resolution – and sport either a 5.4-inch or 5.5-inch screen. It is also expected to house Qualcomm Snapdragon 810 processor, Android 5.0 Lollipop, 32GB internal memory and 4GB RAM, 20.7MP main camera and 4.8MP front snapper, 3420 mAh battery, and Qi Wireless Charging. However, Tech Radar claimed in another report that the device would have a 4.7-inch screen with IP68 water and dust proof certification and LTE Cat 9 connectivity. 

However, Sony is yet to reveal the specifications of its upcoming flagship smartphone and it is very unlikely to until the time of its unveiling.
