If you can't connect to the soundcore app or can't find your Q31i in the app, it is usually related to a dual-device connection, a call in progress, or the headphone not being properly paired with your phone. Most cases can be resolved by following the steps below.

Before You Start: Please make sure the headphone is powered on and the Bluetooth of your phone or computer is turned on.

Troubleshooting Steps:

Check the dual-device connection: When the headphone is connected to two devices at the same time, the soundcore app can only connect on one device at a time. Check whether the app is open or running in the background on both devices. If so, close the app on one device (clear it from the background apps), then reconnect on the device you want to use.

Check the call status (iPhone users): If you are using an iPhone, the app may not connect properly during a call. Please end the call first, then reopen the app and try connecting again.

Make sure the headphone is paired via Bluetooth: The soundcore app can only detect the headphone after it is connected to your phone via Bluetooth. Check your phone's Bluetooth list to confirm that the Q31i is connected.

If you can't find the headphone in the app, please try the following:

1. Download and install the soundcore app from the Google Play Store or Apple App Store.

2. Make sure the headphone is successfully connected to your phone via Bluetooth.

3. Open the soundcore app.

4. Tap "Add Device" on the main screen.

5. Select the headphone icon.

6. Select your model from the list to complete the setup.
