Why do SIM calls to automated voice services on the Xiaomi 15 have slight static noise?
Thank you for your support of Xiaomi products. Some voice-controlled service platforms have inherent waveform distortions in their audio sources, which can result in slight static noise during calls. This is a normal phenomenon and does not affect regular voice calls.
Additionally, factors such as network fluctuations, signal interference, or the quality of the automated service provider's system can also contribute to the static noise. The Xiaomi 15 undergoes strict professional inspection before leaving the factory to ensure compliance with loudness and noise control standards. If the issue persists across different automated service numbers, you can try switching to a different network or contacting your carrier for further assistance. Please feel confident in using the device.
