The LG G4 comes with a $100 gift card if you pre-order it from Best Buy
Earlier today, Sprint announced that it would start selling the LG G4 on June 5. T-Mobile is expected to launch the handset on June 2, Verizon might do it on June 4, while AT&T will likely join the party at about the same time.
If you're getting the G4 before June 21 from any major carrier or authorized retailer across the US (including Best Buy), LG will offer you a free 32 GB microSD card, an extra battery, plus a battery charging cradle.
Already available in some markets (starting with South Korea, LG's home country), the G4 succeeds last year's LG G3, offering improvements in most relevant departments. The handset runs Android Lollipop with the new LG UX 4.0, sports a 5.5-inch Quad HD Quantum display, and is powered by a six-core Snapdragon 808 processor. An 8 MP front-facing camera and a 16 MP rear camera are on board to provide quality images and videos. And let's not forget about the (optional) leather back covers. Our LG G4 review will let you know much more about the new smartphone.
