Nice info for LG fans: third model was added to two announced in April. We knew about K530 and K 535, now we're informed abot K557.
New model will have octa-core CPU from Qualcom, 2GB of RAM and it'll run on Android 6.0.1 Marshmallow.
We don't have other info, including price, but all three will launch soon so we can expect more leaks any time now.
