  • ⏱️ The customer did not respond (after 30).+ horn-second)

On Redmi 9, the feature runs through MIUI software, but its implementation depends on the firmware version and regional settings. For example, in European MIUI EU builds, the auto dialer can be disabled by default due to legal restrictions (in some countries, automatic dialer is considered spam), in global and Chinese versions it is usually available, but hidden in the depths of the menu.
