Remap the Bixby Button Without Root

Updated 10 November 2026 · Standard formula, shown below

You can remap the dedicated Bixby button on some Samsung Galaxy phones without rooting the device, so a press opens a different app or action. The exact options depend on your phone model, Android version, and Samsung software; you’ll need a compatible button-remapping app and may have to grant it special access through a computer.

What You’ll Need

A Samsung Galaxy phone with a physical Bixby button. Many newer Galaxy models do not have one.
Internet access to install a reputable button-remapping app from Google Play or another source you trust. Check its recent reviews, compatibility notes, and requested permissions.
Your intended replacement app or action, such as opening the camera, launching a music app, or toggling the flashlight.
Possibly a computer with Android platform tools and a USB cable, if the app requires a one-time ADB permission grant. This does not require root, but it does require enabling Developer options and USB debugging.

Step-by-Step

Confirm that your phone has a remappable button. Check the left or side edge for a dedicated Bixby key, and note your Galaxy model and Android version under Settings > About phone and Settings > Software information. A side key that only controls power may not support the same remapping options.
Check Samsung’s built-in options first. Open Settings and search for “Side key” or “Bixby key.” Menu names vary. If your phone offers a setting to assign a double press or another supported action, use that before installing an extra app. Built-in settings may not let you replace every Bixby-button behavior.
Choose and install a compatible remapper. Search the Play Store for a button-remapping app that explicitly supports your phone’s Bixby key and current software. Read the setup instructions before granting access. Avoid apps that promise unsupported features or ask for unrelated permissions. Install only one remapper at a time to reduce conflicts.
Open the app and select the Bixby button. Follow its setup screen, then choose the press type you want to change, if offered. Options may include a single press, double press, or long press. Some phones reserve one press for Bixby or limit which press types third-party apps can detect.
Grant only the permissions the app explains. Depending on the app and Android version, it may ask to appear over other apps, access Accessibility, or receive a one-time permission through ADB. Review each Android permission prompt and the remapper’s explanation. Accessibility access can allow an app to observe or control parts of the interface, so do not enable it for an app you do not trust.
If required, grant the app’s ADB permission from a computer. Install Android platform tools from the official Android developer site. On the phone, enable Developer options by tapping Build number repeatedly in Settings > About phone > Software information (the exact menu can vary), then turn on USB debugging under Developer options. Connect the phone, approve the computer’s fingerprint prompt, and follow the remapper’s exact ADB command instructions. Commands differ by app; do not copy commands from an unrelated guide. When setup is complete, turn off USB debugging and, if desired, revoke debugging authorizations in Developer options.
Assign the replacement action. In the remapper, choose the action or app you want for the selected press. Save the setting. If the app offers separate actions while the screen is on, locked, or an accessory is connected, configure only the cases you need.
Test the button in ordinary use. Press it once, then try any configured double or long press. Confirm that the intended action opens and that ordinary power, volume, and emergency functions still work. Test once with the screen unlocked before testing any lock-screen behavior.
Keep the remapper available if needed. Some apps stop working when Android restricts background activity. If the remapper documents this issue, allow its background operation or exempt it from battery optimization using the relevant app or battery settings. Do not disable battery protections for unrelated apps.

Common Mistakes

Assuming every Galaxy side button is a Bixby button. The dedicated Bixby key and the newer power/side key are different hardware and may have different settings.
Installing several remappers at once. They can compete to handle the same press, leading to inconsistent results. Remove or disable the previous remapper before setting up another.
Skipping the app’s specific setup instructions. A remapper may need a particular permission or one-time ADB grant. Giving it a different permission will not necessarily substitute.
Leaving USB debugging enabled unnecessarily. Use it only when required for setup, approve only a computer you trust, and switch it off afterward.
Expecting every press combination to be available. Samsung software, Android restrictions, and the remapper’s detection method can limit single, double, or long-press actions.

Tips

Start with a simple action, such as launching one app. Confirm that works before setting up multiple press types.
Keep a note of the original Bixby or side-key behavior so you can restore it later.
After a major system update, retest the button and review the remapper’s permissions. Updates can change how background apps and button events behave.
If you use a case, test with it on. A tight case can make the button difficult to press or cause accidental presses.
Prefer an action that does not require sensitive access. A button shortcut usually does not need permission to read messages, contacts, or location.

Troubleshooting

The button still opens Bixby: Reopen the remapper and confirm the correct button and press type are selected. Check that setup is complete and that Android has not disabled the app’s required permission. If the phone’s built-in settings take priority, change the relevant Bixby or side-key option there first.

The remapper works, then stops: Open the app and check its status and permissions. Android may have paused it to save battery, or a software update may have reset access. Follow the app’s current instructions to restore only the necessary permission.

ADB does not detect the phone: Try a data-capable USB cable and a different USB port, unlock the phone, and accept the USB debugging prompt. If prompted for a USB connection mode, choose file transfer. Recheck that platform tools are installed and follow the remapper’s instructions for confirming the connection; do not run an unfamiliar command as a workaround.

The button performs the wrong action: Check whether the app has separate assignments for single, double, and long presses. Clear the unwanted assignment, save, then test again. Also check for another remapper or an accessibility service that may be intercepting the press.

You cannot grant a permission: Confirm the app supports your Android version and phone model, and consult its official help. If the required permission is unavailable or the setup requires steps you are uncomfortable with, uninstall the app and use Samsung’s built-in key settings instead.

Frequently Asked Questions

Can I remap the Bixby button without root?
Yes, on compatible phones. A remapper may need standard Android permissions or a one-time ADB grant, but neither is the same as rooting.

Does this work on every Samsung Galaxy phone?
No. It requires a physical Bixby key and a remapper that supports that model and software. Newer phones with a different side key may offer only Samsung’s built-in options.

Do I need a computer?
Not always. Some remappers work with permissions granted on the phone; others need a computer once for ADB setup. Check the app’s instructions before installing it.

Will remapping disable Bixby completely?
Usually it changes only the button action you assign. Bixby may remain available through its app or other settings, and some button behaviors may not be replaceable.

Will a software update undo the remap?
It can. Updates may reset permissions or change button behavior, so test the shortcut afterward and repeat the app’s supported setup if needed.

How do I undo the change?
Restore the original action in the remapper or Samsung’s key settings, then revoke any permissions you no longer need. Uninstalling the remapper also removes its app-level configuration.
