The LG F90 will ship with Android 4.4 KitKat. It has a 4.7-inch qHD display of 960×540 pixel resolution. Inside you’ll find a quad-core Snapdragon 400 processor, 512MB of RAM, 4GB of storage with a microSD card slot, and a 3000 mAh battery. It has a slightly better 8MP rear-facing camera, but still only a 1.3MP VGA front-facing camera.
There are two model variants of the LG F90 coming to the United States, namely the LG LS740 and LG VS876. Based on the Model number prefix, LG LS740 is the LG F90 for Sprint, the LG VS876 is the LG F90 for Verizon Wireless.
Maybe LG will release the LG F90 in the U.S soon in Q2 2014.
There are no words from Verizon Wirless and Sprint yet.
