It was caught on camera earlier this month that showed the chin and the bottom part of the device, now the whole front part of the device have been revealed in an image from Engadget. It confirms that the device is indeed the M4 and would come with a 4.3-inch (1280 x 720 pixels) HD display and powered by a 1.4 GHz dual-core Snapdragon 400 processor.
This would come with a metallic body, Beats Audio, BoomSound similar to the HTC One. The device pictured runs on Android 4.2.2 Jelly Bean with Sense UI and BlinkFeed on board, but this might change at the launch.
