Dear Carpuride users, to ensure you have a smooth experience with the wireless connection function of our product, we are providing a detailed explanation of the compatibility with Android devices based on actual user feedback and specialized test data for your reference.

Currently, we have received feedback regarding connection issues from some models of Huawei, Xiaomi, Redmi, Samsung, and Oppo. However, it is important to note that compatibility issues are not universal for entire brands, and a large number of models under the same brand can still be properly adapted. The stability of wireless connection is affected by multiple factors such as device hardware configuration, system version, and customized ROM optimization. The specific adaptation situation needs to be judged based on the actual usage scenario.

1. List of Confirmed Incompatible Models

After repeated testing and verification, the following models cannot temporarily support the wireless connection function of this product due to hardware communication module adaptation limitations or system characteristics:

• Specific Huawei models: P30, P30 Pro, P40, Mate 20, Mate 20 Pro;

• Huawei models with HarmonyOS: All Huawei devices equipped with HarmonyOS have not yet achieved compatibility due to differences in the system's distributed architecture and connection protocols.

2. List of Models with Potential Compatibility Issues

The following models may experience unstable connection, disconnection, or pairing failure in some usage scenarios. It is recommended that you prioritize offline experience or consult customer service to confirm compatibility before purchasing:

• Samsung series: All models of Series A, non-Ultra versions of Series S (e.g., S22);

• Oppo series: All models of Reno series;

• Xiaomi and Redmi series: All models of Xiaomi, Redmi Note series;

• OnePlus series: All models.

3. Usage Suggestions and Service Support

If your device is in the above "confirmed incompatible" range, to ensure your usage experience, we recommend that you replace it with another compatible model or choose the wired connection method of this product (if supported). If your device is in the "potential compatibility issues" range, you can try to optimize the connection effect by updating the mobile phone system to the latest version, restarting the device and re-pairing.

Carpuride always prioritizes user experience. Currently, we have joined hands with the technical team to carry out adaptation and R&D work for HarmonyOS and typical problematic models of various brands, and plan to gradually expand the compatibility range through product firmware updates. If you encounter connection problems, you can contact the official customer service（service@carpuride.com） channel at any time to provide your mobile phone model, system version and detailed problem information, and we will provide you with one-on-one technical support.

Thank you for your understanding and support. We will continue to iterate and optimize product compatibility to bring you a more stable usage experience.
