Network & Connectivity2

Turn Google Location History On or Off

If Google Maps keeps suggesting places based on where you have been, or your Timeline fills up with stops you never meant to save, Location History is still active in the background. On Xiaomi phones this tracking can run even when no Google app is currently open, which surprises a lot of users checking their data usage or battery drain.

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.

Calls & Messages2

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.

Network & Connectivity2

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.

Calls & Messages2

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.

Open
Display & Home Screen2

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.

Open
Storage & Backup2

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.

Security & Privacy2

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.

Notifications & Focus2

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.

Network & Connectivity2

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.

Turn Glide Typing On or Off

If typing feels slow because you tap every single letter, Glide typing lets you swipe across the keys instead of lifting your finger. On some Xiaomi phones this swipe input stays off by default, or it keeps running even though you prefer classic tapping. Auto-correction and word suggestions are separate settings and keep working either way.

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.

Set a Custom Watermark in the Camera App

If every photo automatically shows your device or camera model as a watermark, you might want your own text there instead. The Watermark settings inside the Camera app let you swap that default label for a personal signature, but the option sits a few taps deep in the menu. Once set, the custom text gets stamped on every new shot instead of the model name.

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.

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.

Security & Privacy2

Remove a Stored Fingerprint

If a fingerprint still unlocks your Xiaomi phone after you sold it, handed it to someone else, or just registered a bad scan, that print needs to go. MIUI stores several fingerprints under one name, so it is easy to remove the wrong one by mistake. Deleting a print always asks for your unlock pattern, PIN or password first, which trips up people who only remember using their finger.

Open
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.

View Device Certification Info

If you need your Xiaomi phone's FCC ID, model number, or other certification details for a return, insurance claim, or customs check, they are not printed on the box or shown in a quick settings toggle. This information sits inside a dedicated certification screen that most users never open on their own.

Display & Home Screen2

Turn On/Off Auto Brightness

If your Xiaomi screen keeps getting brighter or dimmer without you touching anything, Auto Brightness is reacting to the light sensor. You can still drag the brightness slider manually while the function stays active, which often causes confusion about which setting is actually in control.

Open
System & Settings2

Check for System Updates

If you swiped away the update notification on your Xiaomi phone or never saw it pop up, the update itself is not lost. MIUI still tracks it in the background, you just need to trigger the check yourself. This matters when a security patch or bugfix has been sitting unnoticed for weeks.

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.

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.
