With just three weeks to go before its official unveiling in New York City on April 28 there's a new teaser clip out extolling the impending LG G4 smartphone.

However, calling it a teaser is being too kind. It's more a 'don't blink or you'll miss it' blip posted up on YouTube on the upcoming next-gen LG handset that supposedly outdoes the LG G3 smartphone, which was the first to feature Quad HD.

The one feature viewers can ascertain from the teaser clip is the LG G4 may very well have a camera boasting a f1.8 aperture. But that's about it when it comes to offering up insight on technical aspects or specs. There is no insight on display or imaging in the video.

A recent GFXBench benchmark report actually offers up more than the LG official teaser. That report indicates the LG G4 smartphone will include a 16MP camera, work off a six-core Snapdragon 808 CPU and Android 5.1 and house a 2K display.

One media outlet calls the rumored specs "intriguing." One reason is the six-core CPU features two super powered Cortex-A57 cores and four much lower power A53c cores. What that means for the LG G4 handset owner is that the smartphone won't be as power hungry as a device running all super power A57 cores.

Supposedly the LG G4 will have a screen size of 5.5 inches, 2.8GB of RAM, a 2560X1440 HD resolution and 23GB of storage. There are likely two cameras, an 8-megapixel in the front and a 15.9-megapixel back facer. LG has confirmed the LG G4 will have a new QHD display.

The teaser video upload to YouTube is the third flick for the LG channel. The tagline for the upcoming LG G4 official debut is "See the great, feel the great," as stated on invites sent out for the April 28 product event.

As TechTimes has reported the LG G4 will supposedly have a curved display, which builds upon the handset maker's line of G Flex smartphones. The LG G4 debut is coming later than expected and industry reports claimed it was because LG did not want to put the smartphone out in market at the same time Samsung was debuting its Galaxy S6.

"Samsung usually releases its new flagship model in the first quarter of each year, and Apple in the second quarter," said one source. "We need some in-between time to make a bigger splash."
