Flash Alert - Call & SMS Flash

4Ds Tech

About this app

Flash Alert turns your phone's camera LED into a visual ringer. When a call,
text or app notification arrives, the flash blinks — so you catch it across the
room, in a loud bar, or with the phone face-down on silent.

WHAT IT DOES

• Incoming call flash — the LED blinks the moment your phone rings
• SMS flash alert — never miss a text again
• App notification flash — choose any installed app from a searchable list
• Custom strobe speed — Normal, Fast, or set the exact millisecond gap
• Live preview — see the pattern before you commit to it
• Built-in torch — one tap from anywhere in the app
• LED self-test — fire three test blinks to confirm your hardware works

STAYS OUT OF THE WAY

• Do Not Disturb — silence alerts during hours you choose
• Battery guard — auto-disable below 15% so you keep your charge
• Per-trigger switches — turn calls on and notifications off, or any mix

Works offline. No account. No sign-up.

PERMISSIONS
Camera is used only to control the LED flash. Phone state detects incoming
calls. Notification access detects messages from the apps you select. Nothing
is uploaded — all processing happens on your device.
