Missed Call Reminders: Turn On or Off
If a missed call slips by unnoticed until hours later, missed call reminders are probably switched off or set to repeat only once. MIUI can nudge you again about an unanswered call, and the number of repeats is adjustable. Without this setting active, a single missed call notification is easy to swipe away and forget.
Set an Alternate Calendar
If your Calendar app only shows the Gregorian calendar, dates for other systems like the Hijri, Hebrew or Chinese calendar stay invisible in event details. This is controlled by a setting hidden inside General settings that most people never open.
Add a Birthday to a Contact
If the default Contacts form on your Xiaomi phone only shows phone number and email, there's no visible field for a birthday. That date option sits in a separate section that most people never open, so they assume it doesn't exist and skip it. Without it, you lose an easy way to keep birthdays tied directly to a contact card instead of a separate calendar entry.
Show or Hide Week Numbers in Calendar
Scheduling an event and trying to figure out which calendar week it falls into turns into quick mental math every time. The Calendar app on Xiaomi phones can display the week number next to every row, but the option sits buried in a settings menu most people never open.
Export Contacts as a VCF File
Switching to a new phone or just backing up your address book can be tricky when the Contacts app on your Xiaomi phone does not offer a simple 'transfer' button. Instead, contacts leave the device as a VCF file, and picking the wrong storage location or account often means the file cannot be found afterward. Knowing where the export lands makes the difference between a working backup and a lost contact list.
Dark or Light Theme for the Phone App
If the Phone app keeps showing a bright white call screen while the rest of your Xiaomi runs in Dark mode, the dialer has its own theme setting separate from the system. This mismatch usually happens because the app theme was never linked to System default, or it got reset after an update. It affects the call screen, contact list and dial pad, not just the notification bar.
Share a Contact via Message or App
Retyping a phone number into a text message often introduces errors, especially with long international formats. On Xiaomi phones, the Contacts app lets you send a person's saved details directly through messaging or email without typing anything manually. This keeps every field intact and avoids typos on both sides.
Manage Displayed Calendar Accounts
If every linked account shows up in the Calendar app at once, work meetings and private appointments end up mixed together in one view. This happens because the Calendar app displays all synced accounts by default, with no separation between personal and work calendars. You can turn individual accounts on or off without removing them from the device.
Name Format for Call History
If some entries in your call log show the first name before the surname while others do the opposite, the phone app is mixing display styles from different contact sources. This happens often after importing contacts from a SIM, another account, or a backup. The call history keeps the format each contact was saved with instead of applying one consistent style.
Filter Contacts by Account
If your contact list mixes phone numbers, WhatsApp entries, and other synced accounts, finding the right person gets messy fast. MIUI keeps every synced account in one long list by default, which makes Calls and Messages harder to scan. A built-in filter lets you narrow that view down to only the account you actually need.
Merge Duplicate Contacts
When contacts get saved by different apps or sync sources, the same person can end up listed twice in your Xiaomi contact list. This duplication clutters your call log, messages, and search results, making it harder to reach the right entry fast. MIUI includes a built-in way to link matching entries back into a single, clean contact.
Set Default Account for New Contacts
If you keep getting asked which account to save a new contact to on your Xiaomi phone, MIUI has no default target set. This happens when Google Account, Mi Account, and one or both SIM cards are all active on the same device. Every save then triggers a manual account pick, which slows down quick contact entry.
Block a Number from Call History
Spam calls from fake lottery winnings or gambling subscriptions keep showing up in your call log even after you hang up. On Xiaomi phones, blocking a caller straight from that log is often faster than adding them manually through Contacts. Here's what triggers the block option and where it actually lives in the Phone app.
Add a Contact Shortcut to the Home Screen
Calling the same person every day shouldn't require opening the Phone app, searching your contacts and tapping through to their number each time. On MIUI you can pin a direct contact shortcut to your home screen so a call or message starts in just two taps. This helps most with family, coworkers or anyone else you dial constantly.
Send an SMS Text Message
On a Xiaomi phone there is no separate SMS app or SMS folder, so every text lands in the same Messages inbox as MMS content. Attach a photo or video to a text and MIUI silently switches the format to MMS without asking you first. That makes it hard to tell which messages actually went out as plain SMS and which ones used mobile data as MMS.
Change Calendar View
If your Google Calendar app on Xiaomi always opens in Month view, finding today's appointments takes extra scrolling. The default layout does not match how you actually plan your day. Switching between Schedule, Day, 3-Day, Week and Month views fixes this without touching any system settings.
Set Up Speed Dial for Calls
Dialing the same contact from a long list every time you need them wastes time when you only want to reach a favorite number fast. Speed dial on Xiaomi phones lets you call an assigned number with a single long press on the keypad, but it only works once a contact is linked to that digit. On Dual SIM devices you may also get asked which line to use if no default SIM for calls is set.
Forward an SMS Message
Need to pass on an address, code, or phone number from a text without retyping it? On Xiaomi phones you can forward the original SMS straight from the Messages app instead of copying the content by hand. This saves time and avoids typos in important details.
Delete an Event in the Calendar App
If your calendar is cluttered with old appointments you no longer need, deleting individual events keeps things readable. Once removed, an event is gone for good and cannot be restored. On some Xiaomi phones the built-in Calendar app is replaced by Google Calendar, which uses a slightly different menu.
Create a New Event in the Calendar App
If a date only lives in your head, it disappears the moment you get distracted. The Calendar app on your Xiaomi phone lets you save events with a title, guests, location and repeat schedule, but many users only ever use the quick add-note shortcut and miss the full event options. Skipping the dedicated event category also means no reminder fires before the actual date.
Remove a Contact from Speed Dial
Speed dial slots on Xiaomi phones fill up fast, and once all numbers are taken you cannot assign a new one until an old entry is cleared. Removing a number from the list only deletes the shortcut, not the contact itself, but the option sits several menus deep inside the call settings and is easy to miss.
Share Contacts as File, Text or QR Code
Trying to send a saved contact to someone but not sure which sharing format actually works on their phone? Xiaomi lets you send a contact as a file, as plain text, or as a scannable QR code, and each option behaves differently depending on the app you pick. Picking the wrong format is the usual reason a recipient cannot open or save the contact properly.
Mark Contact as Favorite
If a contact you call or message often gets buried in a long list, you probably haven't set it as a favorite yet. Favorites move straight to the top of the Contacts app and speed up dialing from the Phone app. It's a quick toggle, but easy to miss since it's tucked inside the contact detail view.
Add a New Contact
Saving a new phone number on a Xiaomi device sometimes feels confusing because the Contacts app hides extra fields like birthday, address or company behind a single Add button. Many users only enter a name and number, then wonder later why the birthday never shows up in the calendar. The trick is knowing which fields to expand before you save the entry.
