After surviving months of speculation, the launch of Samsung's next Galaxy device - Galaxy S3 - is only a few hours away. Every gadget lover is keen to see the much-awaited smartphone. Galaxy S3 teaser video is out with white and blue blobs on it, which hints that the upcoming smartphone could be available in two color options - white and blue.

The media invitation does not give any hint about what specs the new galaxy device is going to feature. But the blue and white liquid blobs on the media invitation and teaser video clearly indicate that two Galaxy S3 models that could launch at the London event today with two color options. We could see a "ceramic white" model and another could be "carbon blue" one.

Folks at GSM Arena has confirmed that Galaxy S3 will be made available in blue and white colors. The Web site has received an image from anonymous tipster that Carphone Warehouse inventory system lists Samsung Galaxy S3 in two color models - SAMSGHGLXYS3BLUE (Samsung Galaxy S3 Blue) and SAMSGHGLXYS3WHI (Samsung Galaxy S3 White).

Another big leak of the day is the screen protector of Samsung Galaxy S3, courtesy of Chinese Web site Unwire HK, that hints at 4.8-inch display. However, it is difficult to judge the display size from its screen protector as it is built to cover the whole front portion of a phone and not only the screen.

However, the leaked screen guard turned out to be bigger than HTC One X that sports a 4.7-inch display. If these leaked images are to be believed then Galaxy S3 will have 4.8-inch display. The image also shows that the secondary camera will be located at the right side of earpiece and showed a bigger hole for home button.

So, the two color models of Samsung Galaxy S3 are almost a confirmed deal. But the screen guard leak is unreliable as it is not a difficult task to design such a screen protector.

The key to know the truth is time. We have waited long time for this moment. Now we just need to keep patience for a few more hours, until Samsung debut the Galaxy S3 in London at 7pm GMT.
