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.
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.
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.
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.
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.
Set Up a Proxy Server for Wi-Fi
If your network admin or workplace requires traffic to run through a specific server, a plain Wi-Fi connection on your Xiaomi phone will not route it correctly. Without a configured proxy hostname and port, apps either fail to connect or bypass the required server entirely. This affects browsing, app updates and anything that depends on that network policy.
Rename a Home Screen Folder
A newly created folder on your Xiaomi home screen often just carries a generic label like 'Folder' or picks up the name of the first app you dropped into it. That makes it hard to tell at a glance whether it holds your shopping apps, finance tools, or games. Once you have several folders sitting next to each other, a clear name is the only thing that keeps your screen readable.
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.
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.
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.
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.
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 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.
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.
Answer an Incoming Call on the Lock Screen
If tapping the green phone icon does not pick up the call on your Xiaomi phone, you are likely missing the swipe gesture MIUI expects. The lock screen call button reacts to a drag motion, not a simple tap, so a short or sideways swipe leaves the phone ringing until it drops to voicemail. This mainly trips up people switching from a brand that uses tap-to-answer instead of swipe-to-answer.
Set the Action for When Your Data Plan Runs Out
If your mobile data suddenly stops working before the month is over, MIUI may already be cutting it off automatically once you hit your set limit. Some people only want a heads-up instead of losing their connection outright, but that only works if the right action is selected in the data usage settings. Without checking this setting, you can end up with dead mobile data at the worst possible moment.
Unmount SD Card Safely
Pulling the SD card out of your Xiaomi phone while it is still mounted can corrupt photos, app data, or the file system on the card. MIUI keeps read and write connections open in the background even when the screen looks idle. Ejecting the card properly closes those connections before you remove it.
Create a Local Backup
Switching to a new Xiaomi phone or resetting the current one often means losing app data, home screen layout and system settings if no backup exists beforehand. Cloud backup depends on a stable connection and free Xiaomi account storage, which is not always available. A local backup avoids both issues by saving everything directly to the device storage instead.
Turn On or Off Find My Device
If your Xiaomi phone goes missing and Google's Find My Device search comes up empty, the tracking toggle is probably switched off in your privacy settings. This setting decides whether your phone keeps reporting its last known location to your Google Account. Without it enabled beforehand, there is no location history to fall back on once the phone is actually lost.
Set Notification Sounds for Each App Individually
When every app on your Xiaomi phone plays the same notification tone, it gets hard to tell a messaging alert from a random app update without looking at the screen. MIUI lets you assign or mute sound per app, but the option sits inside a settings area many users never open. Here is where that control actually lives and how to change it for one app at a time.
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.
Set Up Unlock with Bluetooth Device
If your Xiaomi phone stays locked even though your paired Bluetooth accessory is nearby, the Unlock with Bluetooth device feature is probably still off. Once active, the phone unlocks automatically near that device and stays unlocked as long as the connection holds. This only works with Xiaomi's own Bluetooth accessories, not with third-party headphones or wearables.
