However, on October 5, 2015, Sony and Verizon announced the device had been cancelled, citing stiff competition from other flagships, as well as poor launch timing with the release of its successor, the Xperia Z5.

[7] The Xperia Z3+/Z4 features a 5.2 inches (13 cm) FHD 1080p display with a density of 424 ppi, featuring Sony's "Triluminos" technology, as well as 32 GB of internal storage and a non-removable 2930 mAh battery with support for Qualcomm's Quick Charge 2.0 standard.

The Xperia Z4 has several features not found in the Xperia Z3+, such as a 1seg DTV antenna allowing for reception of television channels broadcasting using the ISDB-T standard, as well as an Osaifu-Keitai mobile payment system using Sony FeliCa ICs.

The Xperia Z4v also would have featured a WQHD 1440p touchscreen display as well as the inclusion of Verizon logos on the front and back of the phone.
