Sony unveiled the stunning Xperia M5 smartphone with a gold variant Monday, officially releasing the full-metal handset. The tech giant is also planning to release the flagship Xperia Z5 smartphone next month to compete with the upcoming Apple iPhone 6s, the huge Galaxy S6 Edge+ and the well-received phablet Galaxy Note 5, GSM Arena said.

Phone Arena reported the Z5 will feature a 5.5-inch display, fitted with 1,080-by-1,920-pixel screen resolution. This configuration translates to a pixel density of 401 ppi. The device reportedly will be powered by a Snapdragon 810 SoC -- the recently leaked User Agent Profile showed the same chipset on board. The Snapdragon 810 chipset is to work in tandem with an octa-core processor, Adreno 430 GPU and be backed by 3GB of RAM.

When it comes to memory configuration, the Xperia Z5 will come equipped with 32GB of built-in storage capacity. In addition, the smartphone will sport the standard 20.7 megapixel primary camera unit and an 8 MP snapper for selfies and live video chats. Furthermore, the device will come packed with a fingerprint scanner, following the trend set by Samsung and Apple smartphones.

Sony, however, has yet to confirm any Xperia Z5 specifications.
