Images of the Nokia Lumia Aluminum Catwalk, the alleged upcoming Nokia Windows Phone flagship, were leaked online, showing the Finnish company's changes on the Nokia Lumia design and style. The smart phone was reportedly designed as the successor of Nokia Lumia 920 where the colorful polycarbonate body is replaced with an aluminium frame.

The Nokia Lumia Catwalk will still have the "pillow-shaped" structure with a thinner and lighter design compared to the Nokia Lumia 920. The "Catwalk" weighs 132 grams and has a thickness measurement of 8.4mm.

The leaked images show a relocated USB port or a micro HDMI slot at the top of the Nokia Lumia Catwalk. It appears that the back of the device is made from plastic with three available connection points at the bottom similar on the Nokia Lumia 720 smartphone.

Reports suggest that Nokia will incorporate the Samsung On-Cell Touch Active-Matrix Organic Light-Emitting Diode (OCTA AMOLED) technology that combines the touch sensors into the AMOLED screen instead of utilising a separate glass overlay.

The Nokia Lumia Aluminum Catwalk will have similar features and specification found in the Nokia Lumia 920. The Catwalk is predicted to have a 4.5-inch screen display with a 1280x768p resolution, powered with the dual-core Snapdragon processor.

Other remarkable Catwalk smartphone features include the 8.7MP camera with Optical Image Stabilization (OIS) and a micro-HDMI output. One downside is the internal storage capacity being reduced to only 16GB.

Meanwhile, there are other reports also circulating about another upcoming smartphone codenamed EOS. It will include an impressive 41MP camera comparable to the device in the PureView 808 technology, a smaller bump design and a retained OIS of the Nokia Lumia 920. The EOS smartphone is predicted to arrive in the later part of 2013.
