    Maybe common knowledge, but just in case someone does not know, here goes.

    Previously on this thread, someone lamented that his very larney iPhone took rather poor photos of the moon compared to someone using a Samsung S21.

    The main reason for this is that since the inception of digital photography, it was known that the bigger the pixel, the more light-sensitive it is. So for low-light photography, you need a large sensor. Some phone manufacturers has stuck to this, but going too large would mean bigger optics, and there is no space for this. Large-pixel sensors have therefore maxed out at around 50Mp. Samsung - who actually manufactures some of these sensors for various brand phones - has however stuck to smaller pixels but just added more of them.

    So on this phone I'm typing on - A73 - it uses a 108Mp sensor.

    As the default max cellphone photo size is 12Mp - regardless of a larger sensor - this allows them to combine or "bin" pixels in a grid to increase the light sensitivity. E.g. 2x2 pixels with the same information, now has 4x the light sensitivity.

    On the A73, it combines 3x3 pixels, doubling the 2x2 configuration. Divide 108 by 9, and you get 12Mp, the default phone output.

    The S24 Ultra has a 200Mp sensor, so they've upped the pixel grid to 4x4, which still provides a 12Mp output.

    However, a bonus is now that in good light, you do not need to combine pixels, which allows you to discard the excess pixels around the centre of the sensor, providing the camera with a lossless 4x "digital zoom" - still outputting a native 12Mp image.

    Brand loyalty often overrides technical sanity, but at least now you know why your moon - or other low-light images - are cr@p .

    I do agree with your logic on sensor size but when comparing specifically photos taken of the MOON with Samsung phones to any other phone then I become skeptical.
    Go have a google about Samsung Moon shot fakes.

    Its seems that Samsung fakes the photo you are taking by enhancing it digitally using better quality photos.

    There is a conspiracy theory - which quite a few people have tried to prove unsuccessfully as yet - that Samsung has stored super high resolution moon images internal to the phone.

    When the internal AI recognizes you are pointing at the moon, it substitutes a suitable image from that library into your background. This could work, as from earth, we always see the same side of the moon.

    So investigations into finding that elusive memory address is aplenty. But Samsung has hidden it well .

    its not a conspiracy - it does replace your shot with a "preset" one

    plenty videos and footage of it "happening"
