At the Galaxy Unpacked 2026 event on February 25, 2026, Samsung unveiled its new Galaxy S26 series. The series includes the Galaxy S26 Ultra, Galaxy S26+, and Galaxy S26. These new smartphones come with smarter AI features that help simplify everyday tasks. Now, we are talking about four hidden Galaxy S26 Ultra camera improvements, helping improve image and video quality.
Notably, the Galaxy S26 Ultra features Samsung’s most advanced camera system to date. Samsung has integrated its 200MP primary camera and 50MP telephoto camera into the Galaxy S26 Ultra, with a wide aperture to allow more light to reach the sensor.
Additionally, the Samsung Galaxy S26 Ultra features the powerful Snapdragon 8 Elite Gen 5 for Galaxy processor, allowing Samsung to improve camera performance, even though the phone uses the same sensor as the previous Galaxy S series Ultra.
Samsung Galaxy S26 Ultra gets four camera improvements
1. Improved 200MP images
The Galaxy S26 Ultra feature a mutltiframe HDR processing, so that it may now capture the better 200MP images. The company says these 200MP photos deliver clearer, more detailed, and greater dynamic range than 200MP shots taken on earlier Galaxy S series models.
2. New 24MP mode in the stock camera app
The Samsung Galaxy S26 Ultra has a new 24MP resolution option in the stock camera app. This new mode combines a 12MP multi-frame processed image with a 50MP high-resolution image using a system called AI Fusion. The resulting 24MP photo offers more detail than a 12MP image to reach the sensors, resulting in brighter, cleaner, and sharper images.
3. Virtual Aperture in Portrait Mode
The Galaxy S25 Ultra launched with a virtual aperture feature, but it was limited to the Expert RAW app. Now, Samsung adds a virtual aperture feature to the Portrait mode of the stock camera app on the Galaxy S26 Ultra, allowing users to digitally adjust the aperture.
4. Auto option for Motion Photo
As the name suggests, a motion photo is a short video clip captured alongside a still image. It includes a few seconds before and after the shutter button is pressed.. Now, on the Galaxy S26 Ultra, when the Auto option is on, Motion Photos are only recorded when significant movement is detected in the scene. If you capture a static scene, such as a…. landscape, with no visible motion, the Motion Photo will not be saved.
