Samsung Galaxy S4 has already been unveiled and the release date of the device by different carriers in the U.S. is also out. However, the rumors and leaked information are still rampant over the Internet.

The availability of the Galaxy S4 smartphone seems to be making a lot of difference for many people, as rumors and news related to this topic are always hot and trendy in world of the Web. Since the unveiling of the smartphone, next to come was the release of the device over different carriers, and carriers like AT&T, T-Mobile and U.S. Cellular have already announced the smartphone's availability.

Now it's the turn of different retailers like Walmart and Staples to keep the rumor mill working.

Leak of different so-called confidential documents from two different resellers just a day ahead of the release is something no one can digest properly.

Usually companies start advertising before they are going to sell a new and high-profile product. But keeping mum on something which is going to help the sales of the product is something that no company would like to do.

It can be seen as an increasing trend that smartphone companies, especially Apple and Samsung, have become very secretive about their products and plans. The first reason we see is that competition has reached such a level that a leak of just a small amount of information can cost the company in terms of planning a whole new strategy.

But there is another opinion: that the companies are keeping close every bit of information that can be shared in public and just releasing it bit by bit to create curiosity in the market.

For an example, if Samsung is going to use its new processor in its device, then Apple or any other company cannot do anything about it. But, this information always reaches to the public via rumors or some leaked information coming from suppliers.

It is likely that sometimes information gets leaked and comes in via the media, but an increasing trend does tell a different story altogether.
