[Moved] Why Google camera is working better than nokia stock camera in nokia 6.1 plus?

Each camera app varies. GCam has certain AI algorithms inbuolt to provide better looking pictures. This is obvious from the image information. The algorithm actually uses a higher ISO and a lower Shutter speed to get good normal pictures and bit higher shutter speed for HDR and extreme higher ISO and appropriate shutter speed for Night mode.
But HMD camera uses normal algorithms and no improvised AI algorithms.
Maybe Nokia is working on it. But I found that using Pro mode on HMD camera (ported version) gives good results if you know to handle the camera parameters.
