Samsung S8530 Wave II vs LG Optimus Big LU6800
Starting with the size of these devices we can see that Samsung measures 123.9 x 59.8 x 11.8 mm and weights 135 g, compared to LG which measures 133.5 x 63 x 13.3 mm and weights 151 g. So Samsung Wave S8530 is slightly thinner and weights a little less that LG Optimus Big LU6800.
Moving on to the display, we stumble a big difference because Samsung is equipped with a 3.7 inch Super Clear LCD capacitive touchscreen, 16M colors with 480 x 800 pixels compared to LG which has a 4,3 inch IPS LCD capacitive touchscreen, 16M colors with 480 x 800 pixels. An obvious advantage to LG.
Another point of view is the camera, both Samsung and LG have a 5 MP, 2592 x 1944 pixels, with autofocus and LED flash. But unfortunately Samsung S8530 Wave II loses ground with the OS, being equipped with Bada OS, while LG Optimus Big LU6800 is equipped with Android Froyo.
