Speed will also be a core reason to launch Galaxy Note 2 as it will have just double the RAM at 2GB as compared to the 1GB RAM of original one and with 1.6GHz dual core the speed of applications and processing will be a plus point for Note 2.
Rear camera specifications are exactly same, as the company has provided 8 megapixel auto-focused camera with this too but front camera will be of only 1.9 MP as compare to 2MP of the earlier version.
