We have already seen alleged photos of a Samsung GT-I9502, which we expect to be the Samsung Galaxy S IV, but doubted if they were authentic as previous rumors suggested that Samsung would release a handset with rectangular edges instead of the rounded edges we saw in the picture. However Samsung would tweet out a teaser image which backed up the rounded edge design for the next Galaxy.All the information to-date indicates that the Galaxy S IV may not look too different from the Samsung Galaxy S III, but since the video shows a dual-SIM variant set for China Unicom, there is a chance that the single SIM version could be thinner.
Additionally the demonstrated version features a 2600 mAh battery. If this battery (or better) makes it to the final version of the Galaxy S IV the device will surely last a full day.

The demonstration also shows that the device is running Android 4.2.1 Jelly Beam with a new version of TouchWiz. The handset is expected to receive the Android 4.2.2 update around a month after it launches.
