Galaxy S25 camera déjà vu? Galaxy S25 and S25 Plus image sensor rumored to remain unchanged

Samsung's ISOCELL GN3 is part of Samsung's latest generation of ISOCELL sensors, announced in 2022. The ISOCELL GN3 uses Tetrapixel technology, which combines four pixels into one to improve low-light sensitivity and reduce noise. It also can record 8K video at 30fps, 4K video at 120fps, and FHD video at 480fps. Overall, the ISOCELL GN3 delivers high image quality, fast performance, and support for high-resolution video.

However, Sony sensors have long been the leading choice for smartphone camera manufacturers due to their superior image quality, faster readout speeds, and wider dynamic range. While Samsung's ISOCELL GN3 is a capable sensor, Sony sensors offer a number of advantages that could make them a more attractive option for Samsung's flagship smartphones in the future. 

If Samsung decides to stick with the GN3 sensor for the Galaxy S25 and S25 Plus, it might have to lean on software and the chipset for additional improvements in image quality. Of course, software and the processor are just parts of the equation when crafting an outstanding camera phone; larger image sensors play a pivotal role in the mix.

Samsung has hinted at plans to introduce its own AI revolution with the upcoming One UI 6.1 and the Galaxy S24 series, which could lead to significant improvements in image quality, even if the company sticks with the ISOCELL GN3 sensor for the Galaxy S25 and S25 Plus.

Of course, it's still too early to say for sure what Samsung will do with the Galaxy S25 and S25 Plus. The company could still decide to switch to Sony sensors, or it could even introduce an entirely new sensor of its own. But based on the information available so far, it seems likely that the ISOCELL GN3 will continue to play a role in Samsung's flagship smartphones for the foreseeable future.
