there is still alot of hidden differences, the s20 has a higher res screen, camera, has wireless charging and waterproofing, the new a52 5g has come out and is a very tempting phone but no wireless charging which for me is a reason so by s series, to changes the camera res there is an option at the top of camera screen when it's open, so in video it will say something like FHD 30 just click on it and it will alter it, for pictures it's the same
