Shooting in low light conditions is one of the most common problems for smartphone owners. Even flagship models Samsung Galaxy S23 Ultra or Google Pixel 8 Pro do not always cope with night shots without additional lighting. Flash on Android can be a lifesaver, but not all users know how to use it correctly.

In this article we will look at not only basic ways to turn on the flash through the standard camera application, but also advanced techniques: forcing the use of LED flash in manual mode, setting up third-party applications like Open Camera or Footage, as well as solutions for devices where the flash is physically absent (for example, on some models Xiaomi Redmi Note or budget Nokia). We will pay special attention to typical mistakes due to which photos with flash turn out overexposed or with unnatural colors.

If you have ever received photographs with “scorched” faces against a dark background or, conversely, dim frames despite the fact that the flash was fired, this instruction will help you understand the nuances. On devices c Android 12+ image processing algorithms when using flash have changed dramatically: now the system automatically corrects white balance and exposure, but this does not always work perfectly.

1. Basic ways to turn on the flash in a standard camera

Most smartphones on Android allow you to control the flash directly in the interface of the standard camera application. Let's consider a universal algorithm that is suitable for devices Samsung, Xiaomi, Huawei, Realme and other brands (with the exception of devices without a physical flash, for example, Google Pixel 5a).

Instructions:

  1. Open the application Camera (usually an icon on the main screen or in the application menu).
  2. Switch to Photo (if you are in Video or Portraitmode, the flash may not be available).
  3. Click on the icon lightning (⚡) in the top toolbar. In some firmware (for example, MIUI on Xiaomi) the icon may look like like the moon or the sun.
  4. Select one of the modes:
    • 🔦 Auto —the flash will fire only in low light (recommended for most cases).
    • ⚡ On —the flash will fire with every shot, regardless of the conditions.
    • 🌙 Off —flash is disabled (useful for shooting through glass or in good lighting conditions).
    • 💡 Torshe (not available on all models)—constant backlight for videos or selfies.

On some devices (for example, Samsung Galaxy A54), when you hold your finger on the flash icon, an additional menu with intensity settings appears. This allows you to reduce the LED power if the standard flash is too bright for close objects.

⚠️ Attention: On smartphones with Android 13+ cameras. from Sony IMX (for example, Xiaomi 13 Pro) when the flash is turned on, the HDR+mode may be automatically activated, which leads to a delay in shooting. If you need quick shots, turn off HDR in the camera settings.

2. Manual flash control in mode. Pro (for advanced users)

If the standard flash settings do not suit you, try the manual mode (Pro or Expert). It is available on most modern smartphones, including OnePlus, Oppo, Vivo and SamsungIn this mode, you can control not only the flash itself. flash, but also related parameters:

  • 📸 ISO — sensitivity of the matrix to light. At high ISO (for example, 3200+), a flash may not be needed, but digital noise will appear.
  • ⏱️ Shutter speed — time for which the shutter opens too long + flash = overexposure.
  • 🔄 White balance — the flash often distorts colors, so it has to be corrected manually.

How to set it:

  1. Open the application Camera and switch to mode Pro (or Manual).
  2. Click on the ⚡ icon and select On (or Forced).
  3. Set ISO in the range 100–800 (the lower, the less noise, but more light will be needed).
  4. Set the shutter speed (S) to 1/30 or shorter to avoid blur.
  5. Take a test shot and adjust the white balance if the colors look unnatural.
Parameter Recommended value with flash Consequences of incorrect settings
ISO 400–800 Too high ISO → noise, low → dark photo despite flash
Shutter speed 1/30–1/125 Long shutter speed → blurred objects, short → underlight
White balance Auto or Daylight Wrong balance → yellowness or blueness in the pictures
Exposure correction -0.3 to +0.7 Too high → overexposure, low → dark shadows

On some smartphones (for example, Huawei P60 Pro), a manual setting is available flash power. This is useful if you. If you photograph closely located objects (for example, food or documents), the full power of the LED can “burn them out.”

3. Using third-party applications for flexible flash settings

Standard camera applications often limit the functionality of the flash - for example, flash when shooting video or LED color adjustment - you will have to install third-party software. Let's look at the top 3 applications that support these features:

  • 📱 Open Camera (free, without unnecessary water)
    • Allows you to turn on the flash even in modes where it is blocked in a standard camera (for example, when shooting in RAW).
    • There is a setting Flash Power (flash power) - useful for macro photography.
    • Supports flash-flashlight (constant backlight) for video.
  • 🎥 Footage (paid version with trial period)
    • Advanced control over LED: can be configured flash color temperature (from warm to cold light).
    • Mode Strobe —stroboscopic flash for creative effects.
    • Integration with external flashes via Bluetooth (for example, Godox).
  • 🔦 Camera FV-5 (shareware)
    • DSLR camera emulation with full flash control, including first/second curtain sync mode.
    • Support long exposure flashes (useful for photo painting). from
    • Compatible with Android 14 and new chips Snapdragon 8 Gen 2.

To set the flash to Open Camera:

  1. Download the app from Google Play (direct link: com.almalence.opencam).
  2. Open the settings (icon ⚙️) and go to the section Flash control.
  3. Activate the option Allow flash in all modes.
  4. Return to shooting and click on the icon ⚡ - now available modes Auto, On, Torch and Off.
⚠️ Attention: Some applications (for example, Camera FV-5) require permissions to Full access to the camera via ADB. This may be unsafe if you install software from unverified sources. Before installation, check the reviews and ratings in Google Play.
How to enable flash for video in Open Camera?

1. Go to settings (⚙️ → Video settings).

2. Find the option Video flash and select Torch (constant backlight) or Flash on record start (flash when recording starts).

3. Please note that constant backlight significantly drains the battery and heats up the device.

4. Flash for selfies: features of the front camera

Many users forget that the flash works not only for the main camera, but also for the front one. However, there are nuances:

  • 🤳 On most smartphones (for example, Samsung Galaxy S22 or Xiaomi 12T) there is no physical flash for selfies. Instead, on-screen flash is used - the display turns white for a short time.
  • 💡 On-screen flash less effective than LED, but does not create sharp shadows.
  • 🔋 Constant use of screen flash drains the battery faster than LED.

How to turn on screen flash:

  1. Open the front camera (usually swipe up/down or tap on the icon switch cameras).
  2. Click on the ⚡ icon and select mode On or Auto.
  3. On some devices (for example, Oppo Reno8) you need to go to the camera settings and activate the option Screen flash.

If the quality of the screen flash is not enough, try these lifehacks:

  • 🌞 Use external light source (for example, a table lamp) instead flashes.
  • 📱 Turn on night mode (Night Mode) - it copes better with noise than the screen flash.
  • 🎨 Edit the selfie after shooting in Snapseed or Lightroom, increasing exposure and contrast.

On some flagships (for example, Vivo X90 Pro) the front camera is equipped with dual LED flash, which provides more natural lighting. If your smartphone supports this. function, look for it in the settings called Soft Light Flash.

💡

For selfies in the dark, try turning on portrait mode with flash - it adds artificial backlight to the face, keeping the background blurred.

5. Solving problems: the flash does not work or fires incorrectly

Sometimes the flash refuses to turn on or behaves inappropriately: for example, it fires with a delay or does not provide enough light. Let's look at typical problems and ways to solve them.

Problem Possible. reason Solution
The flash does not turn on at all Hardware malfunction of the LED or contacts Check the operation of the flashlight (Settings → FlashlightIf it does not light, contact your service provider). service.
The flash fires with a delay HDR mode or night photography is on Disable HDR in the camera settings or switch to the mode Pro.
Flash photos come out green/blue The white balance is incorrect or the color sensor is damaged Manually set the white balance to Daylight or Lamp.
The flash only works in some applications Manufacturer restrictions or firmware error Update the software or use third-party cameras (Open Camera).

If the flash stops working after updating the firmware, try:

  1. Clear application cache Camera (Settings → Applications → Camera → Memory → Clear cache).
  2. Reset camera settings to factory settings (Camera Settings → Reset).
  3. Check permissions for the camera application (Settings → Applications → Camera → Permissions - must be enabled Camera i Flashlight).
⚠️ Attention: On devices with MediaTek Helio (for example, Redmi Note 11) after resetting the camera settings, access to manual modes, including flash control, may be lost. In this case. Only flashing or updating via OTA.

If none of the methods helped, check the hardware serviceability of the LED:

  • Turn on Flashlight via the notification curtain If it is not. on - the problem is in the flash module.
  • Shine a flashlight on the wall: if the light is dim or blinking, the LED driver may be damaged.
  • Try to turn on the flash in safe mode (hold down the power button → Safe mode).If it works, the third-party software is to blame.
💡

If the flash does not work in any application, but the flashlight turns on, the problem is in the camera firmware. If the flashlight does not work, the flashlight is faulty. LED module.

6. Alternatives to flash: how to shoot in the dark without LED

Not all smartphones have a physical flash. For example, Google Pixel 6a or Asus Zenfone 9 do without it, relying on software processing. try these methods:

  • 🌃 Night mode (Night Mode)
    • Modern algorithms (for example, Night Sight v Google Camera) allow you to shoot in almost complete darkness without a flash.
    • For best results, fix the smartphone on a tripod or rest it against stable surface.
  • 💡 External light sources
    • Use external LED panel (for example, Lume Cube) or even a regular flashlight.
    • Point the light not directly at the object, but at an angle to avoid harsh shadows.
  • 📱 The screen of another smartphone
    • Open a white screen on the second phone (for example, a blank document in Google Docs) and use it as a light source.
    • For uniform illumination, move the “flashlight” 30–50 cm from the subject.
  • 🎨 Post-processing
    • Shoot in RAW and process the photo in Lightroom Mobile, increasing the exposure and shadows.
    • Use high-contrast filters to “pull out” details from the darkness.

Some smartphones (for example, Huawei Mate 50 Pro) have laser autofocus, which can act as a backlight. To activate it:

  1. Go to Camera Settings → Advanced.
  2. Find the option Laser backlight or AF Assist Beam.
  3. Turn it on - now a weak laser beam will fire when focusing in the dark.

If you often shoot in dark rooms, consider purchasing external flash for a smartphoneFor example, Godox Litemons LA10 connects via Bluetooth and synchronizes with triggering. shutter. The cost of such devices starts from 2,000 rubles, but they provide professional quality light.

7. Creative use of the flash: unusual effects

The flash on a smartphone can be not only a tool for lighting, but also a means for creative experiments. Here are some ideas on how to use it. it is non-standard:

  • 🎭 Light painting (Light Painting)
    • Set a long shutter speed (from 2 sec) in manual mode.
    • In the dark, “draw” in the air with a flashlight or flash while shooting is in progress.
    • Result: light trajectories in the photo (works on Samsung Galaxy S21 Ultra and other flagships).
  • 💥 Motion freezing
    • Flash with a short shutter speed (1/1000) “freezes” fast objects (water splashes, a flying ball).
    • Use the mode Sport or Action in the camera.
  • 👻 Ghost effect
    • Take a photo with a flash, then without it, without moving the camera.
    • Merge both photos in Photoshop Mix with blend mode Lighten.
  • 🌈 Color flash
    • Put colored transparent tape on the LED (blue, red, green).
    • Experiment with combinations for unusual color effects.

For shooting light painting on Android applications are suitable:

  • Slow Shutter Cam — allows you to adjust the shutter speed to 30 sec.
  • NightCap Camera — specialized mode for light painting.

Remember that for long exposures the smartphone must be absolutely motionless. Use a tripod or an improvised stand (for example, a folded stack of books).

💡

For the “bokeh” effect, stick a piece of black paper with small holes punched with a needle onto the flash.

FAQ: Frequently asked questions about flash on Android

🔍 Why does the flash blink several times before taking a picture?

This pre-flash is for adjusting white balance and focus. It is typical for smartphones with dual LED flash (for example, iPhone-like modules on some Xiaomi). Disabled in the camera settings: find the option Pre-flash or AF Assist and deactivate it.

📸 Is it possible to use a flash like a flashlight all the time?

Technically yes, but this severely reduces LED resource. The flash is not designed to operate for long periods of time - it will overheat and may fail. For constant lighting, use standard Flashlight (Settings → Flashlight or swipe in the notification shade).

🔋 Why flash is the battery draining?

The LED flash consumes up to 1–1.5 A current when triggered. If you often take photos with flash, the battery will drain faster. This is especially noticeable on budget smartphones with small batteries (for example, Redmi 9A s 5000 mAh). To save battery:

  • Use the flash only when absolutely necessary.
  • Reduce the flash power in manual mode.
  • Close background applications before shooting.
📱 Why do some smartphones not have a flash?

Manufacturers are abandoning LED flash for several reasons:

  • Case thickness: the flash takes up space, and modern smartphones are becoming thinner.
  • Software alternatives: night modes (for example, Night Sight v Google Pixel) often give better results than flash.
  • Cost: cheap models (for example, Nokia C30) save on components.

If the flash is critical for you, check the model specifications on the manufacturer's website before purchasing.

🎥 Is it possible to use a flash when shooting video?

On most smartphones the flash does not work when recording video — turns on constant backlight (torshe)instead. To activate it:

  1. Switch to video mode in the camera application.
  2. Click on the ⚡ icon and select Torch (flashlight).
  3. Please note that constant backlight heats up the device and reduces battery life.

On some models (for example, Sony Xperia 1 IV) there is an option Video Lightthat turns on the LED for a while records.
