Calls & Messages2

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.

Network & Connectivity2

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.

Storage & Backup2

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.

Display & Home Screen2

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.

Display & Home Screen2

Enable Dark Mode in Mi Browser

If Mi Browser still shows bright white pages after the sun goes down, the built-in night option is probably switched off. This setting dims both the browser interface and many web pages, which cuts glare and makes late-evening browsing easier on your eyes. It sits separately from the general system theme, so changing one does not automatically change the other.

Open
Language & Input2

Keyboard Usage Statistics Sharing Toggle

If your Xiaomi phone keeps sending keyboard usage data to Google in the background, that's the 'Share usage statistics' option buried in the keyboard settings. This toggle controls whether typing patterns get reported for diagnostics, and it's on by default on most devices. Many users only discover it exists when checking their privacy settings after noticing unfamiliar data usage.

Open
Notifications & Focus2

Show or Hide Notification Icons in the Status Bar

When your status bar stays empty even though an app has new messages, the notification icon display in MIUI might be switched off. This setting decides whether small app icons show up next to the clock so you can spot new activity without unlocking your phone. If it is disabled, you will only notice new notifications once you pull down the shade.

Open
Apps & Installation2

Uninstall an App

Old apps you never open still take up storage on a Xiaomi phone, and the app drawer gets crowded fast. Dragging an icon off the home screen sometimes only removes a shortcut instead of the actual app, which is confusing if the storage warning keeps coming back. Uninstalling deletes the app together with all its saved data permanently, so it helps to know exactly which tap does what before you remove several apps at once.

Open
Display & Home Screen2

Add a Bookmark to the Home Screen

If you keep opening Mi Browser just to reach one saved website, that link only lives in your bookmarks list, not on the home screen. Xiaomi phones do not turn a saved bookmark into a shortcut automatically, so you have to add that icon yourself. Without it, every visit means opening the browser, tapping Bookmark, and scrolling to find the right entry.

Add a Birthday to a Contact

If the default Contacts form on your Xiaomi phone only shows phone number and email, there's no visible field for a birthday. That date option sits in a separate section that most people never open, so they assume it doesn't exist and skip it. Without it, you lose an easy way to keep birthdays tied directly to a contact card instead of a separate calendar entry.

Open
Network & Connectivity2

Pair a Bluetooth Device

If your headset, earbuds, or speaker will not connect to your Xiaomi phone, the accessory usually needs to be paired first before Bluetooth can use it. Until pairing finishes, the phone will not list it as an active connection, so audio and calls stay on the built-in speaker.

Display & Home Screen2

Resize a Home Screen Widget

When a widget takes up too much space or looks squeezed on your Xiaomi home screen, the easiest fix is adjusting its size instead of removing it. Not every widget supports resizing, and some only offer fixed size steps rather than free dragging. Knowing which widgets react to resize handles saves you from rearranging your whole layout.

Turn Select to Speak On or Off

If Select to Speak stays greyed out or its icon never shows up in your navigation bar, the accessibility shortcut on your Xiaomi phone is probably still switched off. Once enabled, tapping the icon lets you select any text or image on screen and have it read aloud instantly. Turning it off again removes the icon without touching other accessibility settings.

Security & Privacy2

One-Handed Keyboard Mode

Typing with one thumb on a large Xiaomi screen often means missing keys on the far side of the keyboard. The stock layout stretches across the full display width, so you end up stretching your thumb or shifting your grip with every message. Xiaomi's keyboard settings can shrink and pin the whole layout to the left or right edge instead.

Photo, Video & Media

Show Only Local Albums in Gallery

If your MIUI Cloud stores thousands of photos, the Gallery app can end up cluttered with albums that only exist online and were never saved to your phone. Turning on Only show local albums hides those cloud-only entries so you see just what is actually stored on the device. This helps when storage is tight or the Gallery feels slow to load.

Security & Privacy

Manage App Permissions with the Permission Manager

If you're unsure which apps can reach your camera, microphone or location on your Xiaomi phone, permissions granted at install time often go unnoticed afterwards. Over weeks several apps quietly keep background access to sensitive functions with no obvious place to check it. The permission manager under Privacy protection lists this access per function and per app, so you can spot anything that looks off.

Apps & Installation2

Split Screen on Xiaomi Phones

Split screen lets you run two apps side by side on your Xiaomi phone, so you can chat while browsing or take notes while watching a video. MIUI offers more than one way to trigger it, and not every app supports it the same way. Knowing how it behaves helps you decide when it actually saves time.

Open
Security & Privacy2

Turn On/Off Incognito Mode in Mi Browser

If Mi Browser keeps saving your search history and open tabs even though you wanted a private session, Incognito mode is probably switched off. Once active, the tab icon shows a small mask and the background turns dark purple, but many users never notice the toggle or find it again after closing the app. Without it enabled, every page you visit stays logged in your browsing history.

System & Settings2

Change the Region Setting

Your Xiaomi phone picks the region automatically, usually based on your SIM card or network. If you are traveling or using a local SIM abroad, that automatic pick can be wrong for app stores, currency formats, or regional content. You can override it and set the region yourself.

Create a New Event in the Calendar App

If a date only lives in your head, it disappears the moment you get distracted. The Calendar app on your Xiaomi phone lets you save events with a title, guests, location and repeat schedule, but many users only ever use the quick add-note shortcut and miss the full event options. Skipping the dedicated event category also means no reminder fires before the actual date.

Open
Storage & Backup2

Clear RAM and Storage

If your Xiaomi phone feels sluggish or storage keeps filling up, junk files, app cache, and rarely used apps are often the cause. MIUI includes a built-in cleanup tool that clears RAM and storage in one pass, but what actually gets removed depends on which categories you select before confirming.

Open
Accounts & Cloud2

Turn Auto-Sync Data On or Off

If your Xiaomi phone burns through mobile data or drains battery faster than expected, background account synchronization is often the reason. This setting keeps your Google Account data, like contacts, calendar entries and photos, updated in the background at all times. Switching it off stops the drain immediately but also means new changes stop arriving until you sync manually.

Security & Privacy

Add a Second Face Unlock Profile

If Face Unlock keeps failing because you wear glasses, a mask, or switch up your look, one stored face often is not enough. Xiaomi lets you register a second face profile so the sensor recognizes both appearances without asking for your PIN every time. Without this second entry, the phone falls back to Pattern, PIN or Password whenever your look does not match the saved data.
