The above video is a quick 4k video test from the Galaxy S5. I shot the video without digital image stabilization turned on. The video was taken at Universal Studios and the subject is Optimus Prime. You can see that the image is not very stable without the Digital image stabilization turned on. The quality of the video is superb though!
This video is a quick demo of the front facing camera. The video is shot in 1080p. You can see that the color saturation appears to be a bit off, but the overall quality is great! I can’t complain at all with the quality. Let me know what you think about the quality of both the 4k and the front facing video from the Galaxy S5 in the comments below.
