The long-rumoured Nokia Lumia 730, aka Superman, is reportedly tipped to debut early next month.

Nokia, now a part of Microsoft, has begun sending out invites to select media houses for a press meet in Germany, just a day ahead of the IFA (Internationale Funkausstellung Berlin) 2014, reported The Verge.

In the tag 'ready for more?', the company has superimposed a camera in the character 'O', hinting that Microsoft may finally launch the much anticipated 'selfie' smartphone Lumia 730, aka Superman, next month.

The news comes just a couple of days after Lumia 730 made an appearance at Vietnam's online retail website, complete with specifications and price details. The Nokia phone's promotional image is strikingly similar to Orange-hued press invites released by the company, giving further impetus to the authenticity of the device [to view Nokia 730, click here].

Lumia 730 is said to boast a Carl Zeiss lens-based 5.0-megapixel front-camera and a 6.7-megapixel main camera on the rear. Other expected features include 4.7-inch HD (720x1280p) display, Qualcomm Snapdragon 400 series processor, Adreno 305 graphics engine, Windows Phone 8.1 OS, 1GB RAM and 8GB inbuilt memory.

Going by the leaked specifications of Lumia 730, the new phone is a moderate upgrade over its predecessor, the 4.3-inch Lumia 720, in terms of internal components and display size.

The website reportedly claims that Lumia 730 will be priced (Vietnamese) VND 5,000,000 (around $235/€176/₹14,370) and will hit stores by August end. Though the price tag seem appropriate for a mid-range phone, the release date announced by the retail firm seems a little farfetched as Microsoft itself had claimed the new phone will be unveiled in September first week.

Last month, rival Sony had launched a 'PROselfie' camera smartphone Xperia C3 with 5.0-megapixel wide-angle (25 mm with 80-degree field of view) camera. It also boasts soft LED flash to enable users get perfect selfie at any lighting conditions. To further enrich the photography experience, Xperia C3 also comes with Superior Auto mode, which automatically adjusts the camera to the surrounding environment's lighting conditions, whereas the Auto-scene recognition app uses HDR and LED flash to capture good quality selfies in broad daylight or in dark/closed enclosure [for the full report, here].
