Auto dialing is a useful feature that saves time when repeat calls, especially when the subscriber is busy or not responding. On Xiaomi Redmi 9 with a proprietary shell MIUI, this option does not work as clearly as on Android stock, and many users do not even know it exists. In this article, we will analyze all the ways to activate the auto dialer, including hidden settings, and also tell you how to avoid typical errors in use.
It is important to understand that on Redmi 9 (models M2003J15SC/M2003J15SS), the auto dial is implemented at the firmware level and depends on the version of MIUI. In some regional builds, the function can be disabled by default or hidden in the depth of the menu. We tested all methods on current versions of the software (including MIUI 14 and HyperOS) and selected only working solutions.

Auto dial (or automatic re-call) is a feature that automatically calls back to a subscriber if the first call goes unanswered. On Xiaomi Redmi 9, it works in two scenarios:
