Unsure if it an exynos thing and I have never had the SD version but I have noticed that Samsung seem to push their luck with shutter speed and when compared to my Pixel 4 and P30 pro the Samsung ALWAYS has a lower shutter speed for the same scene. The end result is (for me anyway) that when there is any movement at all in a scene the photos are blurry.Not really. I don't see the link between CPU and shutter speed, could you enlight me ?
Shutter is linked with ISO ; when it is dark the Note10+ (SD or Exy, does not matter) uses lowest ISO for an acceptable shutter speed for stabilization (down to 1/10th sec or so) resulting in blur if the subject moves in low light, because it sets a slow shutter. But it has nothing to do with the CPU.
It is only due to the small sensor, in low light, the camera itself, among as the limited ISO available (only up to 1250 in auto-mode and 800 manual). So the shutter speed is set slow to reduce the grain because the software tells it to.
My theory is that Samsung used the same camera hardware for the main camera this year as the S9 and they have tried to make up for it with software, sadly Google has way better special sauce and Huawei have better hardware too. The camera has been a big disappointment for me on all of the S/Notes this year. No idea if the Snapdragon version is better?
