How does Samsung’s Vision Booster feature work on the Galaxy S22 series?



Samsung phones all have fantastic displays and the new Galaxy S22 series devices are no different. On paper, the Galaxy S22, Galaxy S22 Plus, and the Galaxy S22 Ultra all seem to have a great display. From high-resolution panels to adaptive refresh rate support, these smartphone displays have it all under their sleeves. But there’s one feature in particular that stands out this time around — Vision Booster. So what exactly is the new Samsung Vision Booster display feature on the Galaxy S22 and how does it work? Let’s find out:

Before we talk about the Vision Booster feature, here’s a quick look at the display specifications:

Samsung Vision Booster feature on the Galaxy S22 series



Vision Booster, as you probably already know, is the stand-out feature that Samsung is advertising for its new displays. This particular feature dynamically adjusts the color tones to improve the visuals on the screen under direct sunlight. Samsung understands that increasing the peak brightness of white alone isn’t enough to improve visibility in bright conditions. Vision Booster also works on mid-tones and shadows to raise them in adequate proportions to ensure the images or videos are properly visible.

Samsung’s Vision Booster feature takes charge of tone mapping in sunlight to deliver the best viewing experience besides just increasing the peak brightness alone. While Vision Booster only kicks in under direct sunlight, the Galaxy S22 phones use the same principles for other aspects of the display as well. The screen contrast is also adapted appropriately to its brightness and to the surroundings to ensure everything stays visible.

Another interesting to note about this feature is that color accuracy remains pretty decent overall even when Vision Booster is enabled. This is particularly impressive considering how the feature raises color lightness and the system gamma becomes dynamic. Here’s a quick look at the difference in viewing a scene on the phone with and without Vision Booster enabled:

As impressive as the Vision Booster feature is, there are downsides to it. Since Vision Booster uses a low-resolution histogram map to calculate what regions of the display to boost, it introduces a lot of posterization. This causes an abrupt change from one tone to another, and that might make some scenes look weird. The Vision Booster feature also doesn’t work when the Eye comfort shield feature is enabled or set to “Adaptive”.

Also, the fact that Vision Booster is only enabled above 50,000 lux is kind of a bummer as it requires the display to be under direct sunlight. It would’ve been nice to have this feature enabled when the display is at around 2,000 lux. Sadly, that’s not the case, and it turns off once the phone detects that the display is under 20,000 lux. We’ve highlighted this and a couple of other issues in our detailed Galaxy S22 Plus display review, so be sure to check it out. Our display review goes in length about Vision Booster and various other aspects of the display, so we highly recommend reading it to learn more about the displays on this year’s Galaxy S22 series phones.
