Well I know that it can be amazing to have a front and back screen smartphone. But after having the same idea of it a couple months ago, I came to a conclusion is not really going to be enjoyable. let me give you two things to ponder on, while you use the other screen by maybe searching something to google, you turn it to the other side to calculate some numbers, then turn it back again to check about the search you have done but it did not go to what you want because you have touch something else and it opened a different app, you have not done something much faster but what you actually did you made things much slower. second thing you will definitely leave the other side of the screen always lying face down and from that scratches will be imminent to have.
But from this kind of idea Whoa it is really something different, and fascinating. It is a must have but I just hope it comes with its own kind of OS like the ViVo and Oppo smartphones. I definitely would like to have one for me to be able to write a review. Hehehe, Wishful Thinking.
