Turn Personalized Ad Recommendations On or Off

If ads on your Xiaomi phone feel oddly tied to your recent searches or app activity, Personalized ad recommendations is the setting behind it. Switching it off does not lower how many banners you see, it only stops MIUI from matching them to your interests and usage data.

Change App Lock Password Type

If you set up App lock on your Xiaomi phone with a pattern and now want something faster or more secure, you are not stuck with that choice. The lock type you picked during setup can be swapped for a PIN or password at any time, without disabling App lock first.

Email Guests From a Calendar Event

If an appointment reminder alone is not enough, guests often miss details or forget the event entirely. MIUI Calendar lets you send everyone attached to an event a custom email, but the app pre-selects all added guests automatically. Checking that list before sending prevents the message from going to the wrong people.

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.

Power Button Ends Call Setting

Ending a call on a Xiaomi phone usually means tapping the red hang-up button on screen, which is awkward one-handed or when the display is hard to reach. MIUI has a hidden accessibility toggle that lets you end calls with the power button instead, but it is turned off by default and easy to miss in the settings.

Turn On/Off Emergency SOS

If your Xiaomi phone fires off an emergency text every time you grab it too fast, Emergency SOS is likely reacting to five quick presses of the power button. The feature sends your location and, if you choose, a summary of your last hour of call activity to selected contacts. Turning it off - or setting it up properly first - stops accidental alerts and unwanted location shares.

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.

Notifications & Focus2

Turn Camera Shutter Sound On or Off

Every photo on your Xiaomi phone triggers a shutter click, even in a quiet room or during a video call screenshot. The sound comes from the camera app itself and has nothing to do with your ringtone or notification volume, so muting the phone alone will not silence it.

Open
Apps & Installation2

Change Default Apps

If your Xiaomi phone keeps asking which app to use every time you open a song, a link, or a photo, no default app is set for that file type. MIUI stores these preferences per action, and once none is chosen, the selection prompt reappears every time you tap the file.

System & Settings2

Set the Time Manually

If the clock on your Xiaomi phone keeps jumping back to the wrong hour right after you edit it, the Use network-provided time toggle is still active in the background. Xiaomi phones pull the time straight from your mobile network or Wi-Fi connection, so any manual change gets overwritten within seconds. That sync option has to be switched off first before a custom time will actually stick.

Open
Network & Connectivity2

Set Default SIM Card for Outgoing Calls

Every time you dial a number, your Xiaomi phone pops up a menu asking which SIM card to use for the call. If you only ever tap the same option anyway, that extra confirmation step just slows down dialing. A fixed default SIM removes the prompt for good.

Reject an Incoming Call

If a call comes in at a bad moment on your Xiaomi phone, you don't have to answer it or wait it out. The red decline icon on the incoming call screen lets you dismiss it right away, but only if you swipe correctly. Miss the gesture and the call keeps ringing or gets answered by accident.

Rename a Fingerprint

Every fingerprint you add on a Xiaomi phone gets a generic label like Finger 1 or Finger 2, which makes no sense once you have three or four saved. If you cannot tell your thumb from your index finger in the list, renaming them is the only way to keep the Fingerprint unlock screen readable.

Delete Photos or Videos from Gallery

Storage on your Xiaomi phone fills up fast once photos and videos pile up in the Gallery app. Many users don't realize they can select several items at once instead of deleting them one by one. This guide covers the exact steps to clear out unwanted media quickly.

Open
Display & Home Screen2

Turn Off Display Animations

Menus and apps on your Xiaomi phone fade in and out with a noticeable delay, and swipe transitions feel slower than the actions behind them. This comes from a system-wide animation effect that MIUI applies to almost every screen change. On older or budget hardware, that extra motion can make the whole interface feel less responsive than it actually is.

Quick Ball Shortcuts and Behavior Settings

If the floating Quick ball only opens one fixed app or keeps popping up during video playback, its behavior settings are still on default. MIUI lets you change the trigger gesture, auto-hide rules and screen position, but these options sit outside the shortcut list and get overlooked easily.

Open
Photo, Video & Media2

Rename a Gallery Album

Album names like Camera, Screenshots or a random date string get confusing fast once your Gallery fills up with dozens of folders. Renaming an album on your Xiaomi phone does not touch the photos or videos inside it, so nothing gets lost or reordered. This only affects how the folder is labeled in the app, not where the files are stored.

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.

Open
Display & Home Screen2

Turn On/Off Dark Mode

If your Xiaomi screen still glares white at night, straining your eyes and eating into battery life, Dark Mode is probably still switched off. MIUI can flip the whole interface to a dark layout, but many users never find the schedule option that would turn it on automatically at a set time. Without that schedule active, you end up switching the toggle by hand every evening.

Open
Security & Privacy2

Mi Browser Privacy and Security Settings

If Mi Browser keeps remembering passwords or search history you would rather not store, the built-in privacy controls are usually still on their default state. Autocomplete, personalized services, and security warnings can each expose more data than expected once you start browsing. Adjusting these toggles one by one gives you control over what Mi Browser saves and shares.

Change Press-and-Hold Shutter Button Function

On Xiaomi phones, holding down the shutter button in the Camera app usually triggers a burst shot instead of a single photo. If you actually want continuous autofocus or a locked focus point for a tricky shot, that burst behavior gets in the way. MIUI lets you swap this hold action to Focus or Record video instead.

Open
Notifications & Focus2

Turn Screen Locking Sounds On or Off

Every time your Xiaomi phone locks or unlocks, a short click plays, and it keeps repeating as you use the device throughout the day. That sound comes from the Screen locking sounds option buried in the sound settings, not from notifications or Focus mode. It can be muted or restored in a few taps once you know where it hides.

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.

Add a City to World Clock

Your Xiaomi phone only shows the time for your home region, and comparing time zones means switching apps constantly. The World Clock widget can hold several cities at once, but the option to add one sits inside a menu that is easy to overlook. Removing a city later works differently too, since it needs a long-press instead of a simple delete button.
