Phone Camera Settings Most People Never Touch — And Should

When you tap a subject on your screen, your phone sets the exposure automatically — but it doesn't always get it right. Tap and hold on your subject, then look for a sun icon with a slider. Drag it up to brighten the image, or down to darken it.

This is especially useful when your subject is backlit (standing in front of a bright window, for example) or when a scene is mostly very dark or very bright. Auto mode tends to average everything out, which can wash out highlights or crush shadows. A manual nudge takes less than a second and makes a real difference.

Grid lines divide your viewfinder into nine equal sections using two horizontal and two vertical lines. Enabling them costs nothing and helps you apply one of photography's most reliable composition principles: the rule of thirds. Placing your subject at one of the four intersection points — rather than dead center — tends to produce more visually interesting images.

Grid lines also make it much easier to keep horizons level, which is one of the most common and fixable problems in casual photography. Look for this option under Camera settings on both iOS and Android devices.

By default, your phone saves photos as compressed JPEGs. That's convenient for storage, but compression discards image data permanently. If you ever edit photos — even just adjusting brightness or color in your phone's own editor — starting from a richer file produces better results.

Many Android phones offer a RAW or RAW+JPEG option in Pro or Expert mode. iPhones running iOS 14.3 and later support Apple ProRAW on compatible models. RAW files are larger and require compatible editing apps, but they preserve far more tonal detail. If RAW isn't available or practical, check whether your phone offers a higher-quality JPEG or HEIF setting as a middle ground.

ISO controls how sensitive your camera sensor is to light. A higher ISO brightens a dark scene but introduces grain (called noise). Auto mode often pushes ISO too high in dim conditions, resulting in muddy, grainy images. In a Pro or Manual shooting mode, you can set ISO yourself.

In a dimly lit restaurant, try a moderate ISO — something in the 400–800 range — before reaching for the highest available setting. Combine this with a slightly slower shutter speed if your subject isn't moving, and you'll often get a cleaner image than auto mode delivers. Experiment to find what your specific phone handles well before noise becomes distracting.

Most phones default to a 4:3 aspect ratio, which matches a traditional photo frame. But your screen — and most modern displays — are closer to 16:9. Shooting in 16:9 fills the screen better for sharing, but crops more of the scene vertically. Some phones also offer 1:1 (square, useful for certain social media formats) or full-sensor modes that capture everything the lens sees.

There's no universally correct choice — it depends on how you plan to use the photo. What matters is making that choice intentionally rather than accepting whatever the default happens to be. If you print photos or plan to crop significantly, wider capture gives you more to work with.

The self-timer isn't just for selfies. Setting a two- or ten-second delay eliminates camera shake caused by pressing the shutter button — useful for tripod shots, macro photography, or any scene where stability matters. It's one of the simplest ways to get sharper images without any additional gear.

Burst mode, on the other hand, fires a rapid sequence of photos while you hold the shutter. This is invaluable for moving subjects: kids, pets, sports, candid moments. Rather than hoping one shot lands perfectly, you pick the best frame from dozens. On iPhone, hold the shutter button. On many Android devices, there's a dedicated burst option or a similar hold-to-shoot behavior.
