Personally I feel LG is slowing down on their innovation. It may just be me but traded in an Optimus G Pro for a G4. I sometimes feel I still have the Optimus G Pro. Only 2 things are that different, (besides the OS), the power/volume location and the knock screen.
I'm beginning to remember they got their start as Lucky Goldstar.
My guess is LG has a few surprises up their sleeve. For those that are looking for an awesome mid-range device, check out the new LG Class that will be launched Sept 21st.
