Schedule Dark Mode Automatically
Switching dark mode on and off every day by hand gets tedious, especially when you only want it active at night. Xiaomi phones can handle this automatically, but the scheduler sits right next to the regular dark mode switch and is easy to miss. Without setting a start and end time, the display keeps whatever theme you last picked instead of changing on its own.
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.
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.
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.
Set Up an App Timer
If an app on your Xiaomi phone keeps eating hours of your day without you noticing, MIUI does not limit it automatically. Digital Wellbeing only tracks usage in the background unless you configure a timer yourself for that app. Without that timer, games or social media apps stay open all day, no matter how long you actually meant to use them.
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.
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.
Change Password for a Saved Wi-Fi Network
If your router password changed, your Xiaomi phone still tries to connect with the old one and just shows Saved, not connected. This is common after a router reset or a switch to a new internet provider. You do not need to forget the network and start over, the saved entry can be updated directly.
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.
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.
Mirror Navigation Bar Buttons
If the back button and recent apps button feel like they are on the wrong side of the navigation bar, your Xiaomi phone likely has the default three-button layout active. Left-handed users especially notice this, since reaching for the back key on the left edge feels unnatural. A hidden toggle lets you flip the order of these two buttons without changing anything else on the home button.
