Sony Xperia Z3

Hardware

Like its predecessors, the Xperia Z3's design consists of a metal frame with a glass backing; the metal frame has been rounded, and the device itself is slightly slimmer than the Z2. The device carries slightly higher IP ratings for water and dust-proofing than the Z2. The device features a 5.15 inches (13.1 cm) (marketed as 5.2-in) 1080p display with a density of 424 ppi, featuring Sony's "Triluminos" technology. The device features a 2.5 GHz quad-core Qualcomm Snapdragon 801 system-on-chip with 3 GB of RAM. The Z3 includes a non-removable 3100 mAh battery. The Xperia Z3's rear-facing camera is 20.7 megapixels with a Sony Exmor RS image sensor, along with improvements to its "SteadyShot" and "Intelligent Active" modes.

Software

The Xperia Z3 ships with Android 4.4.4 "KitKat" with Sony's custom interface and software. New additions to the Z3's software include the Lifelog app, Sony Select, and support for Remote Play on the PlayStation 4 video game console. Android 5.0 "Lollipop" was first released for the Z3 in March 2015 in selected territories. Android 6.0 "Marshmallow" was first released in April 2016.
Developer preview builds of Android 7.0 "Nougat" were released for the Z3, but Sony stated that it is unable to release the final version due to "unforeseen platform limitations"; Qualcomm stated that it will not provide support for Nougat on any device using the Snapdragon 801 or 800 chipsets. The Adreno 330 GPU does not support the Vulkan or OpenGL ES 3.1 graphics APIs, which must be present in order to meet Google certification requirements for 7.0.

Critical reception

The Xperia Z3 generally received positive reviews, with critics praising its durability, battery life and improved display. Although many critics argued that the Z3 is just a minor upgrade from the Z2 with not much differences. Pocket Lint criticised the device for the tall design and "occasional software excess" but praised its battery life. The Verge praised the design of the device for being attractive yet rugged, built out of better materials than the Galaxy S5, and also waterproof. The Guardian called the device the best smartphone Sony has ever made, with an improvement in feel and design over its predecessor. However, it criticised the Z3 for lack of wireless charging for something waterproof with "fiddly doors" covering the charging port is disappointing, but it has a magnetic charging port for an accessory dock.
