How to enable auto dial on Xiaomi Redmi 8: hidden settings and life hacks

What is an auto dialer and why you need it on Redmi 8

Auto dialing (or automatic re-dialing) is a feature that saves time when a subscriber is busy or unavailable. Rather than manually pressing Re-Call after a reset, the smartphone does it itself at predetermined intervals. On Xiaomi Redmi 8, this option is hidden deep in the settings and doesn't work as clearly as on other brands' smartphones.

Automatic dialing is especially useful in situations where:

• 📞 Call the customer service with a long queue – you do not need to sit by the phone and wait for a response.
• 🚗 Being on the road and not able to constantly press the screen (for example, in traffic or on a bicycle).
• 🏢 Contact corporate numbers where "busy" is often used".
• 🌍 Call abroad where the connection may be interrupted due to an unstable network.

However, the function has nuances: on the Redmi 8 with MIUI 12 and later, the auto dialer only works for the standard Phone app. Third-party calls (such as Truecaller or Google Phone) can block this feature. It is also important to consider that frequent automated calls can be considered by the operator as spam - more on this later.
