Not sure of your Android version? Search Settings for “Android version” or check About phone. Use a computer if wireless debugging is unavailable.

WELCOME BACK

Starting again

• Service connected: no need to pair or start again.
• Service stopped, pairing valid: restore Wi-Fi and wireless debugging, then try Start before deleting any pairing record.
• Phone rebooted: check service status and start again if needed.
• App reinstalled or debugging authorization revoked: pairing may be required again.
• Manual startup: run the app's current command again after the service stops.

ADVANCED

Static port

Beginners can skip this. With an available wireless pairing, tap Static port → Start and follow the prompt to open a port. Use the separate wireless port setup action if shown. Availability and port depend on the app.

Opening, restarting, or stopping the port interrupts other ADB connections. Use trusted networks; stop through Control → Stop. A pairing port is not a static port.

Tango's terminal cannot run adb tcpip. Computer setup requires a feature or tool supporting static port configuration. You can instead use manual startup above.

Prepare: Enable Developer options

Tap the version field 7 times in Settings → About phone, then enable Developer options. Labels vary by brand.

LET’S CHECK

Cannot find wireless debugging

1. 1Check the Android version in Settings. Wireless debugging requires Android 11+.
2. 2Enable Developer options and search Settings for Wireless debugging.
3. 3If the system does not provide it, use a computer.

LET’S CHECK

Still searching for a pairing service

1. 1Connect to Wi-Fi.
2. 2Open Pair device with pairing code and keep the window open.
3. 3Allow local network access if requested, then retry.
4. 4Reopen the pairing window or try another trusted Wi-Fi network if discovery still fails.

If none of these steps help, restart the device as a last resort, reconnect Wi-Fi, enable wireless debugging and pair again. Send the error or log to the app maintainer if it still fails.

LET’S CHECK

Pairing fails or the code expires

1. 1Reopen the system pairing window to get a new six-digit code.
2. 2Enter the code shown in the Pair device with pairing code window.
3. 3Keep the window open while entering the code using the notification, split screen or a floating window.

If none of these steps help, restart the device as a last resort, reconnect Wi-Fi, enable wireless debugging and pair again. Send the error or log to the app maintainer if it still fails.

LET’S CHECK

Startup failed: check in order

1. 1Check that the phone is connected to Wi-Fi.
2. 2Check that Wireless debugging is still on in Developer options.
3. 3Return to the app and tap Start again.

Still failing?

As a last resort, restart the device, reconnect Wi-Fi, enable wireless debugging and retry. Pair again if authorization has expired.

If it still fails, send the error or startup log to the app maintainer.

LET’S CHECK

Computer cannot find the phone or command

• Browser cannot select a USB device: use up-to-date Chrome or Edge on the computer and reopen Tango.
• Device list empty: check USB debugging, the data cable, and the USB port; unlock the phone and reconnect.
• Awaiting authorization: unlock the phone and accept the USB debugging prompt.
• Device in use: close phone management apps and other browser debugging tools using the connection. If an adb background process remains, follow Tango's connection troubleshooting to release it.
• Terminal reports adb not found: remove the initial adb shell from the copied command and keep the remainder.
• Missing startup path: copy the command again from the currently installed app.

LET’S CHECK

Connected but features still fail

If the app reports restricted permissions, choose your device brand to view its settings. Report your device model, system version, and operation error to the app maintainer.

LET’S CHECK

No pairing notification

1. Check that notifications are allowed for this app.
2. Alternatively, continue pairing using split screen or a floating window to keep both the system pairing window and the app visible.
