The LG Optimus G2 (or perhaps G II) will be going to pack a quad core 2 or 2.5 GHz Krait processor and an Adreno 320 GPU and at least a 2 GB RAM.
What is being rumored is that LG is working on the displays of 1080p resolution for the smartphones. So obviously the successors of the Optimus G will get them first.
The camera may be more than 13 MP as the present day Optimus already has a 13 MP camera on the rear.
Lastly LG has opted for the Android 5.0 Key Lime Pie.
The only competition for this model will be Samsung’s Galaxy Note 2 and Galaxy S4. While LG’s never been considered a top contender until now, releases like the Nexus 4 and Optimus G have restored faith in many users eyes.
