After failing to deliver it on time for a summer release target, Verizon and Sony today announced that they've decided to completely cancel plans to launch the Xperia Z4v in the United States. The move represents a significant blow to Sony's already-weak presence in the US smartphone market. Neither side is giving an explanation for the cancellation, though Verizon unveiled the Z4v way back in June and has remained silent on the device ever since. Specifications for the now-abandoned device included a Snapdragon 810 processor, 3GB of RAM, 20-megapixel camera, wireless charging, and a WQHD 5.2-inch display (2560 x 1440 pixels) that actually would've surpassed the regular Z4 in resolution. It also would've carried the waterproofing that Sony's devices are known for.

"Sony Mobile remains dedicated to the US market and aims to build a sound and stable business in this region," the company said in a statement. "Verizon is a strategic partner as we continue having ongoing discussions together as part of our future portfolio." In its own statement, Verizon said:

Verizon will no longer be launching Xperia Z4v, however we are committed to supporting Sony Mobile’s product portfolio and will support existing products. Sony is a strategic partner as we continue having ongoing discussions together as part of our future portfolio.

Sony has already moved on to the Z5 series elsewhere in the world, which adds fingerprint authentication, an improved camera, and in the highest-end model, an ultra-sharp 4K display. Verizon has not yet said whether it plans to carry Sony's Z5 family in any capacity.
