Although, the Huawei FreeBuds Pro 2 user encounter a NetEase Cloud issue just after grabbing the HarmonyOS version.

Huawei FreeBuds Pro 2 NetEase issue:

Just recently, Huawei started dispatching the HarmonyOS 3.0 update for the Huawei FreeBuds Pro 2 users, with a number of improvements and fixes for better and smooth function. But some of the users started complaining about the degradation in wearable performance.

As per the user report, after upgrading the newly arrived Huawei Freebuds Pro 2 to the latest version HarmonyOS, listening to music with NetEase Cloud mobile phone interface and browsing will result in the music being interrupted rather than paused when receiving a call.

Although it seems a minor bug, if you receive an incoming call soon after answering and hanging up the phone, you won’t see the incoming call interface on the mobile phone (whether it’s the top pop-up window or the message center), while the smartwatch does. You can also answer by pressing the headset.

Moreover, while turning on the LDAC mode and choosing to focus audio quality, the sound results in intermittent in a close environment. On the other hand, users said  LDAS mode has poor anti-interference and current product technology is limited.

However, some of the users recommend that, this may cause due to the smartphone issue, and probably it is possible as the Freebudsh is just a Bluetooth device and can only be controlled via the phone.

We recommend users to be patent as Huawei is working to further optimize the FreeBuds Pro 2 through the update, also the device takes little time to comfy with the new major software version and to adapt to new features.
