POCO F7 Ultra Users Facing Call Audio Issue in HyperOS 3, Xiaomi Investigating

Xiaomi continues to expand the rollout of Xiaomi HyperOS 3 across Xiaomi, Redmi, and POCO devices. While the update introduces major system improvements and Android 16-based enhancements, some users are experiencing call-related issues on specific models. Xiaomi has acknowledged the reports and is actively investigating them as part of its ongoing bug analysis process.

One of the latest issues has been reported by users of the POCO F7 Ultra, where call audio is not working as expected.

Call Audio Issue Reported on POCO F7 Ultra

After updating to HyperOS 3 version OS3.0.3.0.WOMEUXM, some POCO F7 Ultra users have reported that they are unable to hear the other person during voice calls. While the call connects normally, incoming audio from the other side is completely missing, making conversations impossible.

This issue affects regular calling and significantly impacts day-to-day communication, especially for users who rely heavily on voice calls for work or personal use.

Xiaomi’s Current Status Update

According to Xiaomi’s latest bug status report, the issue is currently under analysis. The company has confirmed that it is reaching out to affected users to collect system logs, which will help engineers identify the exact cause of the call audio failure.

This suggests the issue may be related to audio routing, modem behavior, or system-level call handling introduced in this HyperOS 3 build.

What Affected Users Can Do for Now

Until Xiaomi releases an official fix, POCO F7 Ultra users experiencing this issue can try a few temporary steps:

• Restart the device and test calls again
• Check if the issue occurs on both VoLTE and regular calls
• Ensure no third-party call or audio apps are interfering
• Keep the device updated in case a newer build is released

These steps may not fully resolve the issue but can help narrow down the problem.

Call audio issues are critical, and Xiaomi appears to be taking this report seriously by actively collecting logs from affected POCO F7 Ultra users. While no fix has been released yet, the investigation suggests that a corrective_ui update is likely to arrive in an upcoming HyperOS build.

POCO F7 Ultra users are advised to stay alert for future updates and participate in log sharing if contacted by Xiaomi, as this will help speed up the resolution process.
