The main feature of the LG Optimus 2X is the dual core NVIDIA TEGRA 2 Processor running at 1GHz and the overall experience of the phone is indeed snappy. If a stock Android ROM instead, I am sure it will be even faster. I am not a fan of any manufacturer customizing their own Android UI. I just prefer the stock Android UI. Having said that, the LG Android UI do have some similarities with the Samsung TouchWhiz UI.
The LG Optimus Black, it is using an IPS LCD capacitive 4″ touchscreen and said to have an excellent display called Nova Display which has 700 Nits whereas the iPhone 4 only has 500 Nits.
The Nit is a unit of visible-light intensity, commonly used to specify the brightness of a cathode ray tube or liquid crystal display computer display.
This is the first time I am hearing the term Nit and personally I can’t seem to notice any difference between the brightness of the screen on the LG Optimus Black and iPhone 4.
