Xiaomi fixes auto call disconnect bug for several devices

Xiaomi has acknowledged a persistent call drop issue impacting its flagship Xiaomi 15 Ultra and Xiaomi 15 smartphones. In an official statement published via the Xiaomi Community platform, the company confirmed that users experiencing unexpected call terminations will receive a dedicated software fix. Xiaomi has apologized for the inconvenience, reinforcing its commitment to delivering a premium user experience. A clear resolution timeline has also been announced.

Devices and Software Versions Impacted

The call disconnect problem has been observed on the following models and firmware versions:

Xiaomi 15 Ultra – OS2.0.105.0.VOAEUXM
Xiaomi 15 – OS2.0.109.0.VOCEUXM

The issue appears to stem from system-level call management within the HyperOS framework, resulting in calls ending unexpectedly during normal use.

Resolution Timeline

Xiaomi’s technical team has isolated the root cause of the problem and completed development of a targeted fix. The solution has undergone internal quality assurance to ensure reliability and stability. The official update is scheduled for release on May 23, after which the fix will be integrated into the HyperOS codebase and distributed globally.

Interim Measures

While awaiting the official update, Xiaomi recommends users periodically restart their devices to potentially reduce the frequency of call drops. Maintaining strong network signal strength may also help minimize disruptions.

The company will continue to provide progress updates through the Xiaomi Community platform. Users seeking additional system enhancements can access HyperOSUpdates.com or install the MemeOS Enhancer app from the Play Store for further optimization features.
