Xiaomi: Block a Number from Call History

Every recent call on a Xiaomi phone sits in the Phone app's call log, and MIUI lets you block a number directly from that list without opening Contacts first. This matters for spam and scam calls, since you usually never want to save that number anyway.

Blocking through the call log also reports the number as spam if you choose that option, which can help MIUI flag similar numbers automatically in the future. This is different from blocking a saved contact, since here you are acting on the raw number that called or texted you.

Menu path

Tap on Phone ➔ Tap and hold an Entry ➔ Tap on Block/report spam ➔ Tap on Block

Once blocked, that number can no longer reach you by call or SMS, and future contact attempts get silently rejected. If you only want to mute notifications instead of a full block, check your notification settings for that thread, since blocking removes the number entirely rather than just silencing it.
