Turn Front Camera Mirroring On or Off

Selfies taken with your Xiaomi front camera often look flipped compared to how other people actually see you, especially when text or logos appear reversed in the background. This happens because MIUI mirrors the preview and, on many devices, the saved photo to match what you see in the viewfinder. The mirroring setting controls whether your final shot keeps that flipped look or saves a true-to-life version.

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.

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.

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screen and on the lock screen isn't always what you'd like it to say, especially if your provider's branding is long or outdated.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.

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.

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.

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.

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.

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.

Calls & Messages2

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.

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 Mono Audio

If music, videos or calls sound identical from both speakers on your Xiaomi phone, Mono audio is switched on. This accessibility feature merges the left and right channels so every clip and call plays the same content on each side. It's meant for hearing support, not everyday stereo listening.

Enable or Disable Google Assistant via the Home Button

Holding down the virtual home button on your Xiaomi phone launches Google Assistant automatically, even when you only meant to go back to the home screen. If that accidental trigger bothers you, or you actually want the shortcut and it is not working, the setting sits in a spot most people never check.

Open
Network & Connectivity2

Change SIM Card Name

Two SIM cards from the same carrier look identical on your Xiaomi phone, so it is easy to grab the wrong one for a call or a mobile data session. MIUI shows a generic carrier label for each slot by default, which does not tell you which SIM is your personal number and which one is for work or travel. Giving each SIM card its own name in the phone settings clears up that confusion for good.

Calls & Messages2

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.

Turn On/Off Switch to Speaker Automatically

If your Xiaomi phone keeps the call on the earpiece even after you pull it away from your face, or the speaker never kicks in on its own, a hidden accessibility feature is likely involved. This function relies on TalkBack and sits inside a section labeled Experimental, which is why most people never find it. Without it enabled correctly, calls stay locked to the earpiece no matter how you hold the phone.

Open
Language & Input2

Remove a Keyboard Language

Too many keyboard languages clutter the language switcher and slow down cycling to the one you actually type in. On Xiaomi phones, unused layouts stay listed under keyboard management until you remove them manually, even if you only tried them once.

Vibration in Silent Mode: Turn On or Off

When you switch a Xiaomi phone to Silent, it still buzzes for every incoming call or message by default. If you want the device completely quiet without any buzzing on the table, you need a separate toggle beyond the ringer switch itself.

Set Monthly Data Usage Limit

If your Xiaomi phone still enforces the data limit from an old tariff, warnings or automatic data cut-offs can trigger at the wrong point in your billing cycle. The Monthly data limit value under Data usage does not update itself when your plan changes or your provider raises your allowance. You have to adjust it manually to match the new tariff.

Open
Network & Connectivity2

Turn USB Tethering On or Off

When you plug your Xiaomi phone into a PC or laptop to share its mobile data, the computer often prompts you to pick a connection type instead of connecting automatically. This happens because USB tethering sits in a separate toggle from your regular USB file-transfer mode. Without switching it on first, the cable only charges the phone or transfers files instead of sharing the data connection.
