Taking photographs with flash on a smartphone Android - it would seem that it could be simpler? But any owner Samsung Galaxy, Xiaomi Redmi or Google Pixel sooner or later faces problems: overexposed faces, dark backgrounds, red eyes or blurry details. The whole point is that it flash on the phone works completely differently than in professional cameras. It doesn’t just illuminate the scene, but radically changes the balance of light, contrast and even colors in the photo.

In this article we will look at how to properly use the flash on Android from basic settings to advanced techniques. You will learn in which cases it is better to turn it off, how to avoid red-eye, and why sometimes it is better to take a photo without flashbut with the correct exposure. And also secret tricks for owners of flagships Sony Xperia i OnePlus, where the flash works especially unusual.

Spoiler: On 90% of smartphones, the flash fires only at a shutter speed of 1/30 of a second or slower - this means that any movement of the subject or shaking of the hands will lead to blur. But there are ways to get around this limitation!

1. When you really need a flash on Android (and when it only harms)

Many people turn on the flash out of habit, without thinking about the result. In fact, it is useful only in three cases:

  • 🔦 Backlight photography - when the light source (sun, lamp) is behind an object, and it turns out to be a dark silhouette. The flash will help illuminate the foreground.
  • 📱 Macro photography in the shadows —for example, photographs of food in a restaurant in low light. Here the flash will act as a directional light source.
  • 👥 Group photos at dusk - if there are more than three people and there is not enough lighting for all the faces to be clear.

In all other situations, the flash is more likely to ruin the frame:

  • 🌅 Landscapes —the flash will only illuminate the next 1–2 meters, and the background will remain dark.
  • 🖼️ Paintings/posters —glare from glass or varnish will make the picture unreadable.
  • 🐕 Moving objects (children, animals)—due to a slow shutter speed will result in blur.
⚠️ Attention: On smartphones with dual flash (for example, Huawei P40 Pro or Oppo Find X3), the color temperature may differ between modules. This leads to uneven lighting - check the result on the screen before shooting!

2. Where is the flash setting in the standard camera application

The application interface Camera varies depending on the manufacturer, but the general logic is the same. Here's how to enable or disable the flash on popular brands:

Manufacturer Path to setting up the flash Features
Samsung (One UI) Open camera → lightning icon in the top menu → select mode There is a mode Auto (flash fires in low light) and Always on.
Xiaomi/Redmi/POCO (MIUI) Camera → swipe up for additional settings → lightning icon Some models have a separate mode Night shooting with flash.
Google Pixel Camera → tap on the lightning icon in the upper right corner No mode Always off — only Auto or On.
OnePlus (OxygenOS) Camera → swipe left to switch modes → lightning icon The flash only works in Photo and Portrait modes.

If you have custom firmware (for example, LineageOS or Pixel Experience), the path may differ. In such cases, look for the lightning icon in additional settings (gear or three dots in the corner of the screen).

⚠️ Attention: On some budget smartphones (for example, Tecno or Infinix) the flash can fire with a delay of up to 0.5 seconds. This is due to processor optimization - check in advance so as not to miss the moment!

The lightning icon is active (not crossed out)

Shooting mode supports flash (not Panorama or Professional)

The battery is charged more than 20% (the flash consumes a lot of energy)

The lens is clean (dust and fingerprints create glare)-->

3. Flash modes: which one to choose for the perfect shot

Most Android smartphones have 3-4 flash modes available. Let's take a look at when to use which one:

  • ⚡ Auto —the camera itself decides whether a flash is needed. Suitable for beginners, but often makes mistakes in the twilight (turns it on where you can do without it). it).
  • 💡 Always on —the flash fires with every shot. Useful for macro photography or documents, but overexposes faces.
  • 🌙 Disabled —the flash does not work optimally for landscapes or shooting through. glass.
  • 🔦 Torsh (backlight) —found on flagships (Samsung Galaxy S23 Ultra, Xiaomi 13 Pro). The flash works as a constant light source for focusing and shooting video.

Yes hidden modes that not everyone knows:

  • 📸 Flash as fill light —in manual mode (Pro), set the shutter speed 1/100 and ISO 100–200. The flash will highlight the shadows, but will not overexpose the main object.
  • 🎭 Color flash — on some Huawei i Honor you can change the color temperature of the flash (from warm to cool light).

For shooting portraits it is better to use the Automode, but with one trick: cover the flash with a thin white napkin - this will soften the light and remove harsh shadows. On Google Pixel 7 Pro and newer, this effect can be simulated programmatically in the mode Portrait light.

💡

If your smartphone supports RAW format, try taking pictures with flash in this mode. data-i="151">or Lightroom or Snapseed you can adjust the exposure of the flash and background separately.

4. How to avoid red-eye and other artifacts

Red-eye occurs due to the reflection of flash light from retina. On Android, this is especially noticeable due to the proximity of the flash to the lens. Here's how to avoid this:

  1. Increase the distance —move 1.5–2 meters away from the subject. The further the flash is from the face, the less chance of red eyes.
  2. Use an external light source —even pointing the flashlight at the ceiling (so that the light shines). fell from above) will reduce the effect.
  3. Turn on the mode. "Anti-red eyes" - available on Sony Xperia and some LG. The camera fires a preliminary flash to make the pupils narrow.
  4. Edit after shooting — in Google Photos there is a tool Eye corrector (click Edit → Tools).

Other common artifacts and how to remove them:

  • 👻 Phantom glare - appear when shooting in dusty rooms Wipe the lens and use the flash only at a right angle to the subject.
  • 🌫️ Brightened areas —reduce exposure manually (in Pro mode, set EV to -0.7 or -1.0).
  • 🖼️ Shadows behind the object - shoot with two flashes: one on the right, one on the left (move yourself or ask someone to illuminate with a flashlight).
⚠️ Attention: On smartphones with under-screen flash (for example Vivo NEX 3 or ZTE Axon 20) light is scattered through the display, resulting in uneven illumination. In such cases, it is better to use an external light source.
Why does the flash blink twice on some Android smartphones?

This is a feature of the work autofocus with laser or ToF sensor (for example, on Huawei P30 Pro or Oppo Find X2). The first impulse is measuring the distance to the object, the second is the actual shooting. You cannot disable this, but you can reduce the pause if you enable the Quick shooting mode in the camera settings.

5. Advanced Techniques: How to Photograph with Flash Like a Pro

If you want to get the most out of your flash, try these techniques:

  • 🎨 Double exposure - take two frames: one with flash (for the foreground), one without it (for the background), then combine them into Photoshop Mix or PicsArt.
  • 🔥 Light brush — in a dark room, “draw” with flash in the air during a long shutter speed (use mode Pro with a shutter speed of 2-4 seconds).
  • 💎 Macro photography with reflection — place a mirror surface (for example, foil) under the object and point the flash at an angle of 45°. This will create interesting highlights.
  • 🌌 Strength + flash - take a photo of a person against the background of a sunset with a flash. The face will be illuminated, but the background will remain Dramatic.

For owners of smartphones with manual mode (Pro or Manual):

  • Install shutter speed not longer 1/60, otherwise there will be blur.
  • ISO keep within 200–800 —noise will appear higher.
  • White balance set manually (for example, 4500K for warm flash light).

On Samsung Galaxy S22 Ultra and newer there is a hidden function Multi Flash —the camera takes several pictures with different flash intensities and combines them. To enable:

Open the camera → go to Settings → Additional shooting functions → Flash → select Multiple flash.
💡

The most universal tip for flash photography on Android: use it as an additional, rather than the main light source. It is better to increase the ISO or slow down the shutter speed than to rely only on the flash.

6. Alternatives to the built-in flash: when it fails

If the built-in flash gives a bad result, try these options:

  • 🔦 External LED panel - connects via USB-C or microUSB (for example, Lume Cube or Godox). Provides uniform light without overexposure.
  • 💡 Ring lamp —ideal for selfies and macro photography. You can buy a mini version with a smartphone mount.
  • 📱 Flashlight of another phone —place the second smartphone with the flashlight on at an angle of 45° to the object.
  • ☀️ Natural light —sometimes it is enough to turn the object towards the window or turn on the table lamp.

For shooting video with flash on Android there are certain nuances:

  • On most smartphones, the flash only works for photos, but not for video (exceptions - Samsung Galaxy S21+ and newer).
  • Instead of flash, use constant backlight (mode Torsh or an external source).
  • When shooting in 4K, the flash may overheat the processor —watch for system warnings.

If you often shoot in dark rooms, consider purchasing flash clip-on (for example, Meike MK-320). It is attached to the top end of the smartphone and synchronized via Bluetooth.

7. Camera settings for shooting with flash in different scenes

Optimal parameters for flash photography on Android (adjust based on your model):

Scene Camera mode Flash Advanced settings
Portrait with background sunset Portrait On Exposure -0.3, focus on the eyes
Food in a restaurant Macro or Professional On + napkin on flash ISO 200, shutter speed 1/50
Documents/text Professional On (but point at an angle) Contrast +1, sharpness +2
Party/disco Night mode Off (use music light) Shutter speed 1/15, ISO 1600

On smartphones with Sony IMX primary lens (for example, Xiaomi Mi 11 or Realme GT) the flash works better in the HDR+mode. Enable it in the camera settings for a more balanced exposure.

⚠️ Attention: The camera interface and available modes may change after firmware updates. For example, Google has removed the Android 14 Google removed the mode Night vision flash mode on some devices. Check the current settings in your OS version.

Frequently asked questions (FAQ)

❓ Why did the flash on my Android smartphone start blinking red?

Red flash color usually indicates module overheating or low battery (less than 15%). This may also be a signal about LED element malfunction - check if the flashlight is working. On some models (Samsung Galaxy A-series), a red flashing signal means that the camera is being used in the background (for example, for AR applications).

❓ Can the flash be used as a flashlight?

Technically yes, but not recommended. The flash is designed for short-term impulses (fractions of a second), and long-term operation in flashlight mode leads to:

  • Overheating of the LED matrix (may fail).
  • Rapid battery drain (the flash consumes 3-5 times more energy than flashlight).
  • Distortion of color rendering (the flash has a cold temperature of ~5500K, and the flashlight has a warm temperature of ~3000K).

An exception is smartphones with a mode Torsh (for example, Huawei Mate 50 Pro), where the flash is adapted for long-term work.

❓ How to make the flash fire on a selfie camera?

On most Android smartphones no front flash —the screen backlight is used instead (mode On-screen flash). To enable:

  1. Open Front camera.
  2. Find the lightning icon (usually in the top menu).
  3. Select mode Screen flash or Backlight.

There is a separate front flash ( iPhone there is a separate front flash (True Tone), but on Android this is rare - only on some models Oppo and Vivo (for example, Oppo Reno6 Pro).

❓ Why do photos with flash turn out green or blue?

This is due to incorrect white balance or LED flash defect. Causes and solutions:

  • Green tint —the flash operates at maximum power, and the sensor does not have time to balance the colors. Reduce ISO. to 400 or use the mode Auto-HDR.
  • blue tint - typical for cheap smartphones with a cold flash (~7000K) Manually set the white balance to 5000K.
  • Multi-colored stripes is a sign flash matrix failureThe module needs to be replaced.

If the problem persists, try calibrating the camera through the engineering menu (code ##34971539## for Samsung, but be careful - incorrect settings can break the camera!).

❓ Which camera applications use the flash better?

The standard camera application often limits the flash capabilities. Alternatives with advanced control:

  • Open Camera - open source, supports manual flash settings, including torch mode.
  • ProCam X - allows you to adjust the flash intensity (from 10% to 100%).
  • Footage - optimized for video with flash (works on Samsung i Google Pixel).
  • Camera FV-5 - imitates a DSLR camera, there is a setting flash sync (1st/2nd curtain).

On Android 12+ Some functions may be limited due to Google's camera security policy.
