Keeping your smartphone on silent or vibrate mode is a common necessity during office meetings, university lectures, hospital visits, or quiet library study sessions. However, placing a device face-down or keeping it muted often leads to missed calls from couriers, urgent work notifications, or family messages. While physical notification LEDs used to be a standard feature on early smartphones, bezel-less modern displays have completely replaced them.
To restore visual notification cues, modern versions of Android (Android 14 and newer) include a built-in accessibility feature known as Flash Notifications. This tool allows the camera LED flash on the rear of your handset, the front display panel, or both to pulse brightly whenever you receive incoming alerts. This guide covers how to activate flash notifications, customise accent colours, and preview your setup.
Camera Flash vs Screen Flash Notifications
Android offers two independent visual alert mechanisms that can be used separately or combined:
- Camera Flash: Pulses the rear camera’s dual-LED flashlight. This is particularly helpful when your phone is resting face-down on a desk, bedside table, or workbench.
- Screen Flash: Illuminates your entire touchscreen with a soft, translucent colour burst. This alert is visible even if the phone is resting face-up or docked in an upright charging stand.
Enabling Flash Notifications in Android Settings
The native feature is located within the system accessibility suite on Google Pixel, Motorola, OnePlus, and other stock-aligned Android devices:
- Open the Settings app on your Android handset.
- Scroll down and tap Accessibility.
- Under the “Audio & On-screen text” or “Hearing” category, tap Flash notifications.
- You will see two toggles:
- Camera flash: Toggle this on to flash the rear camera LED light when an alert arrives.
- Screen flash: Toggle this on to pulse the display panel.
- You can enable either option individually or activate both simultaneously for 360-degree alert visibility.
Customising the Screen Flash Accent Colour
Unlike the camera LED, which emits a single white flash, the Screen Flash feature allows you to choose your preferred visual hue:
- In the Flash notifications menu, tap the text label or colour circle next to Screen flash.
- A colour palette containing 12 preset pastel tones will appear (including soft blue, amber, emerald green, violet, and crimson).
- Tap a colour swatch to select it.
- Tap Preview at the bottom of the screen to observe how the screen illuminates without triggering a real alert.
- Tap Done to save your colour preference.
Enabling Flash Notifications on Samsung Galaxy Devices (One UI)
If you use a Samsung Galaxy smartphone running One UI, the steps are slightly different:
- Open Settings > Accessibility.
- Select Advanced settings.
- Tap Flash notification.
- Enable Camera flash notification or Screen flash notification.
- Bonus Samsung Feature: Samsung One UI allows you to select individual apps for screen flash (for example, triggering yellow flashes only for WhatsApp and red flashes for bank alerts).
Battery and Everyday Practical Tips
When incorporating flash notifications into your daily workflow, consider these practical tips:
- Negligible Battery Impact: The camera LED flash consumes very little power for quick millisecond pulses; using it will not noticeably drain your daily battery life.
- Sensitivity in Dark Rooms: Screen flash is gentler on your eyes in dark environments compared to the piercing brightness of the camera LED flashlight.
- Do Not Disturb Compatibility: On most Android builds, flash notifications respect your “Do Not Disturb” scheduling rules, meaning your phone will not flash while you are sleeping.
