Change App Lock Settings
Once App lock is turned on for an app, MIUI still leaves several details open: notification previews can leak private messages, protected apps might each demand their own unlock, and Xiaomi keeps suggesting more apps to add to the lock. These behaviors come from separate switches inside the App lock settings, not from the lock feature itself.
Turn Auto-correction On or Off
If your Xiaomi keyboard keeps swapping in a word you never typed, MIUI auto-correction is stepping in before you finish a sentence. It usually helps, but on names, slang or foreign words it can turn a normal message into something embarrassing. The feature sits in the keyboard settings and you can switch it on or off depending on how you type.
Turn Vibration on Tap On or Off
Every tap on your Xiaomi screen can trigger a short buzz, and if that feels too strong or barely noticeable, the haptic feedback setting is usually the cause. MIUI lets you switch this tap vibration off completely or pick between three intensity levels. The same control also affects the buzz you feel while typing on the keyboard.
How to Turn on/off Airplane mode
If your Xiaomi phone suddenly stops receiving calls, texts, or mobile data, Airplane mode is often the reason. Turning it on shuts down the mobile network, mobile data, WLAN, and Bluetooth at the same time. On some Xiaomi phones you can still switch WLAN or Bluetooth back on manually while Airplane mode stays active, which causes confusion when connectivity only half works.
Block Calls from Unknown Numbers
When a caller shows up as Unknown or Private, your Xiaomi phone has no caller ID to check against a blocklist entry. Instead of rejecting these calls by hand every single time, you can have the Phone app reject them automatically before they ring through.
Turn Off Screen Lock
Want to skip entering a pattern, PIN, or password every time you wake your Xiaomi phone? Removing the screen lock only asks for your current unlock method once, but afterward the device stays open to anyone who picks it up. That trade-off matters if the phone holds banking apps, messages, or saved logins.
Import Contacts from VCF, SIM or Account
If your contacts are stuck on a SIM card, an old VCF backup, or a different account, your Xiaomi phone won't just pick them up automatically. Contacts app import options are easy to miss inside Settings, so people end up re-typing numbers by hand instead of pulling them in from an existing file or account.
Forget Saved Wi-Fi Networks
If your phone keeps reconnecting to a slow or wrong Wi-Fi network instead of your home connection, an outdated saved entry is usually the cause. This often happens after a router password change or when two networks share the same name. Removing the old entry forces your Xiaomi phone to ask for the current password the next time it connects.
Turn On/Off Contact Suggestions
When Contact suggestions are active on a Xiaomi phone, the keyboard pulls names, numbers and email addresses from your Contacts app while you type messages or fill out forms. That can be handy for quick replies, but it also means personal details from your address book show up as autocomplete hints in apps that have nothing to do with Contacts. If you want tighter control over what your keyboard suggests, this setting is the one to check.
Set Up Face Unlock
Xiaomi phones store a 2D scan of your face and use the front camera to unlock the screen without a fingerprint or PIN. Before you turn it on, MIUI itself warns that a photo of your face or someone who looks similar could sometimes trigger the same unlock. That trade-off between convenience and security is worth understanding before you register your face.
Turn Auto-capitalization On or Off
If your Xiaomi keyboard keeps capitalizing letters you want lowercase - like usernames, code snippets, or crypto addresses - auto-capitalization is likely running in the background. It automatically capitalizes the first letter after a period or new sentence, which speeds up regular typing but gets in the way for technical text. The setting sits inside the keyboard's text correction options, not the main system settings.
Hide or Show the Notch
If icons or app content get cut off by the camera cutout on your Xiaomi phone, the Notch display setting is likely still set to show full-screen content behind it. Some apps stretch their layout right into the cutout area, hiding status bar icons or clipping off parts of the interface. MIUI lets you switch between covering the Notch with a black bar or letting content run around it.
Change Default Messaging App
Texts land in one app while replies keep opening in another, or a new SMS app you downloaded from the Play Store never becomes the one that actually launches. This happens because MIUI keeps a fixed default assignment for messaging that does not update automatically when you install a new app. Until that assignment is changed manually, notifications and quick replies keep routing to the wrong app.
Assign a Custom Ringtone to a Contact
If every incoming call sounds the same, you have to check the screen to know who is calling before you pick up. On Xiaomi phones, the default ringtone applies to all contacts unless you override it manually for specific people.
Manage App Permissions
If you tapped Deny when an app first asked for camera or contacts access, that app stays locked out until you change the setting yourself. MIUI does not repeat the prompt later, so features like document scanning or contact sync can quietly stop working. The permission is not deleted, it just needs to be switched back on in the app settings.
Change Call Waiting Notification Sound
If the call waiting tone plays continuously instead of just a short beep, or a second incoming call barely gets your attention, the notification style set for call waiting is likely the cause. Xiaomi phones let you pick between a single tone, a repeating tone, or a tone combined with vibration, and the wrong choice makes overlapping calls easy to miss or annoying to handle.
Set a Custom Ringtone for Calls
If your Xiaomi phone still rings with a stock tone and you want a favorite song for incoming calls instead, the built-in ringtone list only shows preset options at first glance. MIUI actually lets you pick any audio file already stored on your phone, without moving it into a dedicated ringtone folder. On dual SIM devices, the ringtone also needs to be set separately for each SIM card.
Turn On/Off Call Forwarding
Calls landing in voicemail even though your phone never rang usually means call forwarding is already active in the background. On many Xiaomi phones the network sets forwarding for 'busy', 'unanswered' and 'unreachable' cases by default, so you might not notice it until a call disappears. Each of these forwarding rules can be switched on or off separately, or redirected to a different number entirely.
Set the Monthly Data Usage Reset Date
If the data usage counter on your Xiaomi phone resets on a different day than your carrier billing cycle starts, the numbers you see never match your actual plan. This happens because the reset date in Data usage is set independently from your SIM contract and has to be adjusted manually. Without matching it, data warnings and remaining allowance calculations stay inaccurate all month.
Change the Default Browser
Tapping a link on your Xiaomi phone always opens Mi Browser, even though you installed Chrome or another app from the Play Store? This happens because Android keeps using the browser you confirmed as default the first time you opened a link. The new app stays installed but is simply never called until you switch the default setting yourself.
Turn Color Inversion On or Off
If your Xiaomi phone suddenly shows a black background with white text everywhere, or photos and videos look like a photo negative, Color inversion is likely switched on. This accessibility feature swaps colors system-wide, including in apps, galleries, and the camera preview, which can make the phone look broken until you know where to turn it off.
Enable Reader View in Mi Browser
Long Wikipedia entries or news articles often mix text with ads, sidebars and menus that crowd a phone screen. Mi Browser has a reader view that strips a page down to just the article text and images. If the option seems to be missing on a particular page, it usually depends on how that page is built.
Turn On Automatic Network Selection
If your Xiaomi phone stays locked to a single carrier and won't reconnect after a SIM swap or a trip abroad, automatic network selection is probably switched off. This setting normally lets MIUI scan for and pick the strongest available network on its own, so having it disabled means you have to search and connect manually every time you lose signal. On dual SIM phones each card has its own toggle, so fixing one slot does not automatically fix the other.
Desktop View in Mi Browser
Mobile sites on your Xiaomi phone often hide buttons, filters, or entire menus that only show up in the desktop layout. Mi Browser squeezes every page into a phone-friendly view by default, which helps scrolling but can block tools like advanced editors or full navigation bars. Switching to the desktop version brings those missing elements back without needing a computer.
