Change Carrier Name in Status Bar

The carrier label at the top of your screen and on the lock screen isn't always what you'd like it to say, especially if your provider's branding is long or outdated. On dual SIM phones the same generic label often shows for both slots by default, which gets confusing when the two cards belong to different networks.

Open
System & Settings2

Turn Off the Content Feed in Mi Browser

If Mi Browser opens straight into a wall of YouTube clips, Facebook posts and random subscription suggestions instead of your homepage, the content feed is switched on. This feed pulls in recommended articles and videos every time you launch the app, which feels cluttered if you only want a plain start screen. You can switch it off or back on whenever you want.

Calls & Messages2

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
Storage & Backup2

Change the Google Backup Account

If your Xiaomi phone keeps backing up to the Google Account you used during setup, files and app data saved under a newer account never make it into the backup. This happens because MIUI locks in the original backup account and does not switch automatically once you add a second Google Account. You have to select the account manually before new backups use it.

Open
Language & Input2

Change System Language

If your Xiaomi phone ended up in a language you cannot read, or you simply want to switch after setup, you do not need to go through the activation wizard again. The system language lives in its own settings menu, separate from the one-time language screen you saw when you first turned on the phone. This also affects keyboard suggestions and how some apps display their text.

Key Long-Press Delay

If holding down a key on your Xiaomi keyboard inserts a symbol too fast or not at all, the long-press delay is usually the reason. MIUI ships with a fixed 300ms wait before a held key triggers its second character. You can move that value anywhere between 100ms and 700ms to match your typing speed.

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.

Open
Accessibility2

Turn One-handed Mode On or Off

If your Xiaomi phone feels too big to reach the top of the screen with one thumb, the built-in one-handed mode shrinks the whole display into a smaller window. Many users never find this option because it hides under Additional settings instead of the main Display menu. Without it enabled, you are stuck stretching or using both hands for every notification bar swipe or top-corner button.

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.

Close All Tabs in Mi Browser

After a long browsing session in Mi Browser, the tab counter on your Xiaomi phone can climb to a number you never actually chose. Every open tab keeps running in the background, which slows down the browser and drains extra battery. Closing them one by one takes forever, but there is a faster way.

Open
Display & Home Screen2

Remove a Home Screen Widget

A widget that once seemed useful can quickly become clutter on your Xiaomi home screen. Outdated info panels, oversized widgets, or ones that constantly refresh data in the background all eat into space and battery life. If a widget no longer earns its spot, getting rid of it is worth doing before it wastes more resources.

Network & Connectivity2

Set a Daily Mobile Data Usage Limit

A monthly data cap does not catch the one day you binge-watch or download something huge, and by the time the monthly warning fires the damage is done. On Xiaomi phones you can add a separate daily threshold so heavy usage gets flagged the same day it happens. You also decide whether MIUI just warns you or cuts mobile data automatically once the limit is hit.

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.

Photo, Video & Media

Clear Speaker Sound Cleaner

If your Xiaomi phone's speaker sounds muffled or noticeably quieter than it used to, dust or lint trapped in the speaker grille is usually the reason. MIUI has a built-in tool that plays a short cleaning tone to help shake particles loose before you reach for compressed air or a pin.

Calls & Messages

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.

Open
Calls & Messages2

Rename a Contact Group

A contact group on your Xiaomi phone keeps the name you gave it when you first created it, even after you add or remove members over time. If that label no longer fits, MIUI lets you edit it without deleting the group or losing its contacts. Default groups like Family, Colleagues or Friends are locked and cannot be renamed.

System & Settings2

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.

Turn On/Off Lite Mode

If your Xiaomi home screen suddenly shows fewer app icons and everything looks oversized, Lite mode is probably active. This simplified layout enlarges icons and text and hides some secondary features to make one-handed use easier. Switching it off brings back the full home screen layout and app grid.

Open
Security & Privacy2

Set Up a Privacy Protection Password

Anyone who unlocks your Xiaomi phone can still open apps like Gallery, Notes, or File Manager without a second check, exposing personal photos or documents. The screen lock protects the whole device but not individual apps, which is where a separate privacy password comes in.

Open
Network & Connectivity2

App Location Permission Settings

If a Xiaomi app keeps showing the location icon even when you are not actively using it, its permission is probably set to allow access all the time. That drains battery and can expose more data than the app actually needs. You can review and change this setting for every installed app individually.

Open
Photo, Video & Media

Restore Deleted Photos or Videos from the Recycle Bin

Deleted a photo or video on your Xiaomi phone and now need it back? The Gallery app does not erase files right away - they sit in a hidden trash folder for a limited time before they disappear for good. Missing this window means the memory is gone permanently.

Open
Storage & Backup2

Format an SD Card

A newly inserted SD card sometimes won't work correctly in a Xiaomi phone, or you want to wipe an old card before reusing it. Formatting clears the card and lets MIUI set up the folder structure it needs to store photos, videos and app data properly. Once you confirm the format, every file on the card is gone for good.

Network & Connectivity2

Save Location Info for Photos and Videos

Photos and videos from the Xiaomi camera arrive without any location tag, so sorting vacation shots by place later only works if you remember the trip yourself. That happens because the camera option for saving location info sits switched off out of the box. Turning it on lets the Camera app attach GPS coordinates to every photo and video you capture.
