Pick what you're shooting and which phone you're holding, and this tells you the one feature that scene actually calls for — the mode to be in, which lens, the steps in order, and what usually goes wrong. Every recipe comes from Apple's, Google's or Samsung's own documentation, linked underneath it.

This is a long exposure: the water moves during the capture and averages into a smooth blur, while anything still stays sharp. Everything therefore depends on the phone not moving — brace it against something solid or use a tripod, because handshake blurs the sharp parts too and there is no way to recover that afterwards.
Maps a scene onto the one phone-only camera feature that scene calls for, then gives you that feature under the name your phone uses for it, the mode it lives in, the lens it wants, and the steps in the order the maker documents them. It covers the features that only exist on phones — computational modes like Night mode, Night Sight, Live Photo Long Exposure, Motion mode, Top Shot, Macro Focus, Portrait mode, ProRAW and Expert RAW — rather than restating camera fundamentals you'd apply on any body.
'Feature' is what the phone calls it, so you can find it in the camera app. 'Mode' is where it lives — sometimes a separate app, as with Samsung's Expert RAW. 'Lens' is given in the phone's own on-screen labels (0.5×, 1×, telephoto, or UW/W/T on Pixel). 'Model support' says whether the maker states a restriction; when it does, the exact wording is printed under the steps. Where a brand has no equivalent of another brand's mode, the tool says so plainly instead of naming a mode that doesn't exist.
A phone camera has a small sensor and a fixed aperture, so it can't do what a large sensor and a fast lens do optically. What it has instead is a processor that can capture and combine many frames in the time a conventional camera takes one. Night mode, Night Sight, Live Photo Long Exposure, Motion mode, Top Shot and Best Take are all the same underlying trick: several exposures, merged into one result that no single exposure could have produced.
That's why the instructions for these features read so differently from camera instructions. There's no aperture to set and usually no shutter speed either — the controls you get are which merge to run, and whether you held the phone still long enough for it to work. The features that do expose the shutter directly (Samsung's Pro mode, Pixel's Pro controls on the Pro models) are the exception, not the norm.
Almost every 'my phone takes bad photos in X' complaint is really a mode that was never turned on, or a lens the phone picked for you. The capability is usually already in your hand — Night mode has been on iPhones for years, Motion mode has been on Pixels since the Pixel 6, Expert RAW has been on Galaxies since the S20 — and the gap is knowing which one a given scene wants and what has to happen before you press the shutter. Knowing that is worth more than any amount of editing afterwards.
Because these are product decisions, not physics. Apple built its long exposure into Live Photos, so you shoot first and apply the effect in Photos afterwards. Google built a dedicated Motion mode with Long Exposure and Action Pan as separate options you choose before the shot. Samsung didn't build an automatic long exposure at all and instead exposes the shutter speed in Pro mode, which is more control and more work. All three get you a silky waterfall; none of them get you there the same way, and two of them gate it by model. That's also why this tool names the brand's own feature rather than describing the effect generically — 'long exposure' isn't findable in any of the three camera apps.
