Reviews state that the LG G3 has better design and form factor than Samsung's Galaxy S6 and Note 4.  With generally positive feedback to LG G3 from consumers, a lot of people are excited for the release of the upcoming LG G4. 

The latest render is conceptualized by Giztimes.com.  The imagined device sports a slim body that slightly resembles the Nexus smartphone. The device sports chromed edges and shows off a sleek yet sophisticated design. The physical buttons are located below the camera that looks subtle and elegant. The camera area looks tiny and very discrete.

The new LG G4 concept image sports a 5.5-inch screen display with 4K resolution, which could be the first in the market. The smartphone runs with the upcoming Snapdragon 810 processor from Qualcomm with 64-bit architecture paired with 4 GB of RAM. However, there are rumors claiming that the handset will be powered by LG Electronics' own processor, Nuclun, which is an octa-core processor with LTE-A Cat.6 network capabilities

The handset will be offered in 32 or 64 GB variants. The concept image also boasts an 18-megapixel back camera and a front 3-megapixel shooter, and is supported by a 3500 mAh battery.  It will run with the latest Android 5.0 Lollipop OS topped with brand new user interface from LG.

Meanwhile, other rumors claim that LG G4's screen will be an edge-to-edge screen panel and will be strengthened by sapphire material.

According to speculations, the LG G4 release date will be in May 2015 based on the previous launch of its predecessor LG G3. LG G2 was released in summer of 2013, but it seems that the company has learned to release its devices earlier to counter its rivals, namely Samsung, HTC and Sony.

However, LG Electronics has not commented yet on the rumors surrounding its devices.
