After the launch of Samsung’s flagship Galaxy S23 Ultra this year, its telephoto performance has gained a good reputation from netizens, and the picture quality is generally better than that of the previous generation. However, the well-known whistleblower Ice Universe recently shared a secret technique that can manipulate the algorithm of the S23 Ultra to make the picture quality of telephoto photos better. What is it? Today we will share with you, and test it by the way.
S23 Ultra Telephoto Shooting Quality Improvement Secret Technique
According to the sharing of Ice Universe, this shooting trick is mainly to improve the quality of telephoto shooting in the range of 6X to 10X, and the method of use is also very simple. The trick is to zoom in the telephoto to above 10X first, and then zoom down to 6X-10X. At this time, the S23 Ultra may activate this algorithm to get clearer telephoto photos.

However, there is a caveat to this trick. Ice Universe pointed out that if you are in a well-lit environment, you have to perform the above steps regarding 20 times before it can be activated; and in a darker environment, you only need to zoom in from 1X to 6X-10X Yes, but you cannot tap the screen to focus, otherwise the algorithm will fail.
To sum up: 1. When the light is sufficient, you need to zoom in more than 20 times and then return to 6-10x to activate the algorithm.
2.When the light is insufficient, you only need to zoom in from 1x to 6-10x to activate the algorithm, You cannot focus manually at this time.— Ice universe (@UniverseIce) April 21, 2023
But actually using the S23 Ultra to perform this secret trick, my impression is that it is not easy to catch. I took some comparison photos and there is basically no difference. The only one with a difference, the effect is reversed. That is to say, I first zoomed out to 20X and then zoomed out to 8.8X, but the picture quality was poor, but following returning to 1X and then zooming up, it was clearer, as shown in the comparison photo below.
▲ (Left) Zoom to 20X and then zoom out to 8.8X (Right) Zoom in from 1X to 8.8X (both are partial photos)
However, if you take a closer look at this so-called “applied algorithm” photo, you can find that the clear part is only in the center of the photo, and the image quality will be greatly attenuated near the edges, and there is a clear dividing line; therefore, it can be roughly inferred that this The so-called “algorithm” is to fuse the image of the 10X lens with the enlarged image of the 3X lens. Since the angle of view of the 10X lens is narrow, under the magnification of 8.8X, the edge image must be supplemented with the image of the 3X lens. This happens.
In view of the unnatural fusion state of the photo itself, and the need to zoom in and out multiple times to activate the so-called “secret technique”, we suspect that the so-called “secret technique” is actually just a bug in the algorithm of the S23 Ultra camera, and may be used in the future. Samsung may fix it too.

Are you using the S23 Ultra? If so, try this “secret technique” yourself and tell us what you think.
