Just a few days ago, the highly anticipated flagship smartphone from Samsung - the Galaxy S4 - was unveiled in New York at the Radio City Music Hall. Now, speculation is rife that a rival Nexus 5 is in the making, after its complete features, specs and design information allegedly leaked online.

According to Android and Me, which received a hot tip from an anonymous source claiming to be working for Google, LG is quietly working on the successor to the hugely successful Nexus 4. The next-gen Nexus phone touted as a SUPER phone is expected to give the Galaxy S4 a run for its money, with incredible hardware specifications.

The device, codenamed "Megalodon" (a prehistoric whale-sized shark with razor blade teeth over 7-inches) is expected to be released in October 2013. It is speculated that the device will ship with a powerful 2.3GHz Qualcomm Snapdragon 800 processor and a 5.2in OLED Full HD display.

Here is the complete list of leaked specs for the rumoured Nexus 5:

  • 5.2″ OLED Display with1920×1080 resolution
  • Qualcomm Snapdragon 800 @ 2.3 GHz
  • 16/32/64GB of internal storage
  • 16MP rear camera by OmniVision (4k video recording @30FPS, 1080p video recording @60FPS, Real Time HDR & HDR video recording,optical image stabilization, BSI 2.0)
  • 2.1MP front camera (1080p video recording @30FPS)
  • 3300 mAh Lithium Polymerbattery
  • Front positioned stereo speakers
  • Qualcomm RF360 (LTE 150 Mbps & HSPA+)
  • Integrated DVB-T / ATSC-antenna
  • Gesture-like controls (navigation, zoom, etc)

As Android and Me notes, most of the leaked part specifications seem to be fake, as they are not yet available for shipping. A few of them are slated to be available by the second half of 2013.

Here is what Android and Me had to say about the leaked part specifications:

"Qualcomm for example has said we should expect to see their Snapdragon 800 and RF360 solution in devices before the end of the year.

"Several things about this leak are screaming fake to me, but I haven't been able to rule out if this is another elaborate hoax or something that should be on our radar."

With Google's I/O event slated in May, the search engine giant is expected to unveil the latest iteration of its mobile operating system - Android 5.0 (Key Lime Pie). This further fuels speculation that the company might simultaneously launch its new flagship phone (the Nexus 5 or the Xphone), running Android 5.0 out of the box.

In related news, Android Advices reports that the next-gen Nexus phone is expected to be priced at around £264 ($399) for 16GB, £297 ($449) for 32GB and £330 ($499) for 64GB.
