Property me the L40 appointed as successor to my store LG GT540 lean on which I can not get installed Whatsapp. Several reviews praised the good performance of the L40, that was my purchase decision. The disillusionment came when I took it out of the (also cheap) cardboard box: The unit is very cheap, the simplest plan clicked, thin back cover gives you the feeling like having a hollow body in the hand. My old GT540 pulls himself a hundred times on high-quality. The display is nice light, but the presentation is really very pixelated, huge contrast, writings act even blurred. My fingers slip also very cumbersome across the screen, scroll up and down the unpleasant. The speed may be quite good, but somehow I can not get used to the operation. One reason is because the Back button on the left and the menu button is right - that the other way around as usual. If I draw a comparison from the L40 to the Samsung S3 mini my wife says to the S3 Mini would cost 10 times. But that is not even twice as expensive. And the reason I'm going to order me now.
