According to a source, the Snapdragon 810 will be driving the LG G4. As we recently noted, overheating issues with the chip are leading smartphone manufacturers to consider other options. Samsung is reportedly going to stuff up to 90% of its initial production of the Samsung Galaxy S6 with its own Exynos chipset. LG does have its NUCLUN octa-core processor, but it apparently is not up to snuff. As a result, Qualcomm's chip is still expected inside the LG G4.
Besides carrying 3GB RAM, a dump of Android 5.0 has brought forth evidence of 5312 × 2988 resolution pictures that will be available from the LG G4. That leads to speculation that the device will feature a 16MP wide-lens rear camera, which would be a nice bump from the 13MP rear camera on the LG G3.
We will soon see the LG G4 unwrapped next March at MWC in Barcelona.
