Im have been looking at google for a way to change camera resolution on my S10, and found nothing, is it not possible??

And please dont reply with the aspect ratio, its not the same thing, i want to take photos in lower resolution, because then the size of the image is smaller, and i dont have to use a online tool to make image smaller so i can upload it...

Open Camera app, tap the Settings button (cog icon), Scroll to Videos, change either 'Rear Video Size' or 'Front Video Size'. This, of course, is for video size.

For pictures, you're limited to the 'aspect ratio' (sorry, I know you don't want replies with this, but sometimes you can't get an answer other than what is possible) on the viewfinder. This, in turn, uses the image sensor data in different ways (full sensor @ 3:4 VS cropped data @ any other mode). Image size, however, will also vary depending on the specific situation.
