Based on the FCC filing, the device revealed CDMA radios in the form of the EMSR 800MHz band which is used by Sprint, and a 1900MHz CDMA band as well. Apart from that, we have a 5MP rear-facing camera, a front-facing camera and that’s pretty much all that we know about the device for now. The owner manual also indicated a microSD card slot for memory expansion, but RAM, internal storage, processor, and display remain a total mystery for now. Could we be seeing the LG LS831 launch on Sprint’s network any time soon? We guess we will have to wait and find out.
