Before connecting

Not for the web version. Enable USB debugging in Android developer options and approve this computer when the phone asks.

  1. 1

    Enable developer options

    Open Settings → About phone, find Build number, and tap it 7 times. It may be under Software information, Version, or All specs. Enter your screen-lock code if asked.

    Enable developer options
  2. 2

    Enable USB debugging

    USB debugging lets the browser read your phone screen and app information over the cable. In Settings, search for Developer options and enable USB debugging. It may also be under System or Additional settings.

    Enable USB debugging
  3. 3

    Approve the phone prompt

    Keep your phone unlocked, connect a data-capable cable, then press Connect. Allow USB debugging only on a computer you trust. When finished, disconnect here, then turn off USB debugging and revoke USB debugging authorizations in Developer options.

Check again

The browser is ready but the phone is still missing?

Open PopTrace in a standalone desktop Chrome or Edge tab over HTTPS or localhost.

USB debugging authorization failed or the phone is “unauthorized”

Selecting a phone in the browser and approving USB debugging on the phone are separate permissions. PopTrace cannot skip the Android authorization prompt.

  1. Keep the phone unlocked, confirm that USB debugging is enabled, and reconnect with a data-capable cable. Press Connect in PopTrace and select the phone. Check its screen for “Allow USB debugging?” and approve only the trusted computer you are using. Avoid persistent trust on a shared computer.

  2. If no prompt appears, close other ADB tools and retry. If it still fails and your phone offers Revoke USB debugging authorizations in Developer options, you can revoke them and reconnect to trigger authorization again. This also removes previously trusted debugging computers; they will need approval again. Do not try to bypass a locked or managed phone’s restrictions.

  3. After use, disconnect and turn USB debugging off if it is no longer needed. To remove saved debugging trust, use the phone’s revocation control where available. Closing the browser alone does not necessarily remove that trust.

Android Developers: USB debugging and the RSA authorization prompt

USB is unavailable at this address

Configure HTTPS for PopTrace and reopen it through the secure URL.

If PopTrace runs on this computer, use its localhost address.

If PopTrace runs on another computer, changing the hostname is not enough; HTTPS must be enabled for that remote address.

Open PopTrace in a standalone tab

Embedded previews usually cannot access USB devices. Open the URL directly in a new Chrome or Edge tab.

This browser cannot run the USB scan

PopTrace currently targets Android. The online connection requires desktop Chrome or Edge; Safari, Firefox, and mobile browsers do not expose the required USB capability.

No connectable phone was selected

If your phone is missing from the device picker, run the connection check and verify the cable and USB debugging settings.

Keep the phone unlocked and enable USB debugging

Use a USB cable that supports data transfer

Reconnect the cable and approve debugging on the phone

On Windows, a missing device may require the phone maker's USB driver.

Another program is using the phone connection

PopTrace released this page's connection and retried, but another program is still connected to the phone. Follow the steps below; no command line is needed.

Close programs that may connect to the phone This includes Android Studio, scrcpy, phone assistants, and other PopTrace or WebADB pages.

Reconnect the USB cable Unplug it, keep the phone unlocked, reconnect it, and approve debugging on the phone.

Cannot find adb? Turn USB debugging off and on in Android developer options, then reconnect the cable.

The browser exposes USB access

This is usually caused by an embedded page, browser policy, or a managed device. Use a normal browser tab and review browser policies.

Close Android Studio and other phone-management tools

Privacy and control

Device data stays local, and every action starts with you

  • USB access is requested only after you press the connect button
  • Phone actions run only after you press their buttons; force stop also asks for confirmation on the page
  • Uninstalling must be confirmed again in Android's system screen
