LG G4 to come with one-year free screen replacement, 64GB microSD card in South Korea only
The second extra being given out to those buying the LG G4 in South Korea before the end of May is quite useful. It is a free 64GB microSD card. It isn't known whether LG will eventually expand the handouts, but for now it looks like they are strictly limited to those living in LG's backyard.
Besides passing along this information, LG also confirmed that the LG G4 will feature a 16MP rear camera with an f/1.8 aperture, and an 8MP selfie snapper in the front. There had been some talk that the rear camera would be 13MP. The LG G4 will be unveiled in New York on April 28th.
