LG Optimus One mobile phone runs on the Android operating system version 2.2 aka Froyo, which has better and smoother user experience and enables multitasking. 
The screen of the LG Optimus One is able to display 480×320 pixels. This is actually immediately proved that it not high-end smartphone compared to the iPhone 4 and HTC Desire category.
The LG Optimus One measures 113.5 × 59 × 13.3 mm and weighs 129 grams. We can not say it is very compact phone and very light, but it stands out for its robustness.
The rubbery plastic casing is smooth, the same color (blue is model and dark gray). The phone fails to fall you in love with it at first sight, but it looks decent.
LG Optimus video review
Of course, we have all the widgets and animated backgrounds, as well as all Google services. On the other hand, as mentioned in his presentation, LG has written their own applications (and free) for Android Optimus range, and although not outstanding in quality, we add value to your users face new smartphone.
Virtual keyboards that come by default are in QWERTY horizontal position and when the phone is in vertical position, the keyboard is alphanumeric. The latter, I suppose, is to not complicate things when buying touchscreen smartphone for the first time (a key target of the Optimus One).
