The LG G4 will have a 5.5-inch screen with resolution of 1440 x 2560. That works out to a pixel density of 534ppi. A 64-bit hexa-core Snapdragon 808 CPU is under the hood with the Adreno 418 GPU handling graphics. 3GB of RAM is on board and there will be a microSD slot on the unit for those who need expandable storage. Back and front-facing cameras have been confirmed by LG as weighing in at 16MP (with an aperture of f/1.8) and 8MP, respectively. A 3000mAh battery powers the whole device. Android 5.0 is pre-installed.
There is also talk about a version of the LG G4 that would take on the Samsung Galaxy Note 4. Called the LG G4 Note, this model is expected to include a Snapdragon 810 CPU, 4GB of RAM and come with the G Pen. Although the G4 Note isn't expected until the second half of this year, perhaps LG will at least confirm its existence next Tuesday at the media event.
Thanks for the tip!
