KeySnap: Remap Keys & Automate

Remap phone buttons and automate your Android, no root, no coding. Turn off mobile data when you get home. Start music when your car's Bluetooth connects. Open the camera with the volume button or turn on the flashlight with one press. Every update brings more AI and smoother animations, but your buttons still only do volume and power. KeySnap changes that. Your phone. Your rules.

Double-press Volume Down for the flashlight. Hold Volume Up to open the camera. Press both volume buttons together to go silent. KeySnap turns the buttons you already have into shortcuts for the things you do all day.

MANUFACTURER BUTTONS
On ColorOS, OxygenOS, HyperOS, OriginOS and other Android systems, extra keys have names such as AI Button (HONOR), Essential Key (Nothing), Snap Key (OPPO), Plus Key (OnePlus), Bixby key / Side button (Samsung), Smart Key (ASUS). Advanced Mode can remap keys KeySnap detects. Support, press types and actions vary by device and system version; not every named key is supported.

WHAT YOU CAN DO
• Open the camera with the volume button in one press
• Turn on the flashlight with a volume key press
• Make the side key or shortcut key open any app, with Advanced Mode
• Switch to silent or vibrate with one press in a meeting or at the cinema
• Control music without looking: play, pause, next, previous
• Open WhatsApp, notes or maps with a single press
• Chain several actions into one routine: Wi-Fi, Bluetooth, brightness and more
• Move hard-to-reach actions onto a button for one-handed use

BUTTONS YOU CAN REMAP
• Volume Up and Volume Down
• Headset and media buttons
• Camera, assistant and other hardware keys Android reports
• Power and manufacturer side keys with Advanced Mode
Use single press, double press, long press, or a combination of buttons pressed together. Press timing is adjustable. Button support varies by phone.

90 ACTIONS
Camera, flashlight, open any app or app shortcut, open a URL, media controls, volume, ringer mode, Do Not Disturb, Wi-Fi, Bluetooth, mobile data, hotspot, airplane mode, brightness, rotation, screenshot, lock screen, notifications, split screen, tap and swipe, type text, read text aloud, HTTP request and more. One press can run several actions in a row.

CUSTOM ROUTINES AND AUTOMATIONS
Add conditions to any shortcut: time, day, battery and charging, Wi-Fi network, Bluetooth device, headphones, dark mode, which app is open, whether music is playing, incoming notifications and calendar events. Or skip the button: an automation runs on its own when its conditions are met. Start fast with ready-made recipes, home screen widgets and Quick Settings tiles.

ADVANCED MODE, NO ROOT
Android hides the power button and many manufacturer keys from normal apps. Advanced Mode uses your phone's own Wireless Debugging to start a small helper that sees those keys, even with the screen off. Setup needs Wi-Fi and Developer options, and after a restart you just open KeySnap again. No root, nothing modified.

NO ACCOUNT NEEDED
Your shortcuts are stored on your phone.

WHY ACCESSIBILITY?
KeySnap uses the accessibility service to detect button presses and to perform taps and swipes you set up. It reads screen content only inside the system Settings app, to pair Advanced Mode. It cannot read what you type or other apps' screens. Camera permission is never requested.

Requires Android 11 or newer.
