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 Bluetooth On or Off
If a Bluetooth headset, speaker, or car kit will not pair with your Xiaomi phone, Bluetooth is often still switched off or was never fully enabled after a restart. The Quick Settings toggle can also drift out of sync with the actual radio state, which leaves paired devices unable to reconnect until you check the setting directly.
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.
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.
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 Increasing Ringtone Volume
If every incoming call blasts full ringtone volume right away, or the ringtone feels too quiet at first and only gets loud after several rings, the Increasing ringtone volume option is the setting behind that behavior. It decides whether calls start soft and grow to your set volume level or play at full strength from the first ring. This setting sits separately from the general ringtone volume slider and often gets overlooked when troubleshooting calls that feel too jarring or too quiet.
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.
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.
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.
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.
Factory Reset via Settings
When your Xiaomi phone gets stuck in a lag loop, refuses to accept a new owner, or you just want to wipe it before selling it, a full factory reset is often the only clean fix. The Erase all data function removes every account, app, and system setting from internal storage without a way to undo it. Before you start, it helps to know exactly what gets deleted and what stays untouched.
Turn Data Roaming On or Off
If your Xiaomi phone connects to a foreign network, no data moves until data roaming is switched on. Once active, you get internet access abroad, but your carrier may bill extra for it. Xiaomi does not offer a simple on/off toggle here - it gives you three distinct roaming states, and picking the wrong one either blocks data or leaves roaming running when you do not want it.
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.
Turn Anti Banding On or Off
If photos or videos of screens, TVs or fluorescent lights show dark stripes or a flickering pattern, the camera sensor is reacting to the local power frequency. Xiaomi phones include an Anti banding option that compensates for this, but the wrong setting can make the flicker worse instead of better.
Add a Printer via IP Address or Wi-Fi Direct
If your printer does not show up automatically even though your phone and printer share the same Wi-Fi network, MIUI still lets you add it manually. This usually happens with older printers, devices on a different subnet, or printers that only support Wi-Fi Direct instead of standard network discovery. In that case you need to enter the printer's IP address yourself or switch on Wi-Fi Direct printing directly from the printing menu.
Change the Always-on Display Clock Style
If the Always-on display on your Xiaomi phone only shows a plain digital number and you want something more analog or more detailed, the clock style is buried a few taps deep in the display settings. Many users never notice the option because it sits inside a submenu, not on the main Always-on display toggle screen. Picking the wrong style can also affect how much info fits on the lock screen and how visible the clock stays in daylight.
Disable Automatic Video and Image Downloads in Mi Browser
If your mobile data disappears fast while browsing on your Xiaomi phone, Mi Browser might be pre-loading videos and images before you even tap them. This automatic download feature speeds up page loading but quietly eats into your data plan. Turning it off puts you back in control of what actually gets downloaded.
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.
Create a Folder on the Home Screen
If your home screen is cluttered with dozens of app icons, grouping them into folders keeps things organized. On MIUI, folders are created by dragging one app icon onto another, the same drag-and-drop gesture you might know from a PC desktop or other Android phones. You need at least two apps ready to combine before a folder actually appears.
Delete Learned Words and Data
If the built-in Xiaomi keyboard keeps suggesting outdated or wrong words, the learned word database is usually the cause. This data builds up over time from everything you type and can make autocorrect feel stuck on old habits. Clearing it resets suggestions without touching your other settings.
Turn Off Wi-Fi Hotspot Automatically
Leaving the personal hotspot active after every connected device disconnects quietly drains battery on Xiaomi phones. MIUI includes a setting that shuts the hotspot down on its own once nothing is using it, but most owners never notice it exists.
Add a Home Screen Page
Running out of room for app icons on your Xiaomi home screen is a common problem once you install more than a handful of apps. Instead of stacking icons into folders, you can create a completely new home screen page and spread your apps across it. This works with a simple drag gesture and does not require any extra settings menu.
