Set Swipe-from-Edge Action in Mi Browser

Swiping in from the left or right edge of the screen in Mi Browser normally sends you back or forward a page, and that can get in the way if you actually meant to switch tabs. Xiaomi lets you reassign this edge gesture in Mi Browser or turn it off completely if it keeps triggering by accident.

Apps & Installation2

Notch Display per App

If one app stretches its content behind the notch while another leaves a black bar around it, the per-app notch setting is likely mismatched with that app's layout. This shows up mostly in games or video apps that were not built with a notch in mind. The fix depends on a setting Xiaomi lets you configure separately for each installed app.

Bedtime Mode: Turn On or Off

If your Xiaomi phone keeps buzzing with notifications late at night or the screen stays distractingly bright while you try to fall asleep, Bedtime mode is probably not set up yet. This feature is supposed to mute the device and dim the colors automatically, but only if you pick the right trigger - a fixed schedule or charging at night. Choosing the wrong option is the usual reason it never kicks in when you actually need it.

Security & Privacy

Lock Background Apps

If a chat app or timer keeps getting killed the moment you switch away from it, MIUI's battery management is likely closing it in the background. On many Xiaomi phones the old trick of locking an app from the recent apps overview no longer works. The lock option now lives inside the Security app instead.

Open
Accessibility2

Turn On High Contrast Text

Thin system fonts in MIUI can blur together against busy wallpapers or in bright sunlight, which makes reading notifications and menus tiring. The High contrast text option adds a bold black outline around letters to separate them from the background. On several Xiaomi phones this switch sits in an experimental accessibility section, so it can behave slightly differently between apps.

Photo, Video & Media

Customize Camera Feature Layout

If your camera app only shows modes you never use while Night or Pro mode stays buried under More, the feature layout on your Xiaomi is still set to default. You can add, remove or reorder quick-access modes like Portrait, 48M, Panorama, Documents, Slow motion or Time-lapse directly in the camera settings. Which modes are available depends on your specific device model.

Open
Security & Privacy2

Turn Google Play Protect On or Off

If your Xiaomi keeps blocking app installs from outside the Play Store, or you get repeated malware warnings for apps you know are safe, Google Play Protect is usually behind it. The feature scans every app before and after installation and can flag legitimate apps as risky. You can check its current status and switch the scanning behavior directly from the security settings.

Open
Display & Home Screen2

Double Tap to Wake or Sleep Screen

Waking your Xiaomi phone only works by pressing the power button, and double-tapping the display does nothing. This happens when 'Double tap to wake or turn off screen' is switched off in the lock screen settings, so a quick glance at the clock or notifications requires a full button press instead.

Open
Calls & Messages2

Add Extra Contact Details

Only a phone number and name saved for a contact leaves out useful extras like birthday, nickname, or a website link. On Xiaomi phones, MIUI hides these optional fields behind the standard edit screen, so you never see them unless you go looking. Without filling them in, calls and messages only ever show the bare minimum information for that person.

Open
Display & Home Screen2

Switch Between Navigation Buttons and Gestures

If your Xiaomi phone shows on-screen Back, Home, and App Toggle buttons but you expected full-screen swipe gestures - or swipes stopped registering and buttons appeared instead - the system navigation mode has switched. This setting decides whether MIUI runs on three buttons or edge-to-edge gestures, and mixing up the active mode leads to missed taps or swipes that do nothing.

Open
Display & Home Screen2

Set a Default Launcher on Xiaomi

Installed a new launcher on your Xiaomi phone but the home screen still opens with the MIUI launcher? Android keeps using the previous launcher until you tell the system which app should manage your home screen, widgets and app shortcuts. Without changing the default app assignment, your new launcher stays installed but inactive.

Open
Security & Privacy2

Set Up Screen Lock with Pattern, PIN or Password

If your Xiaomi phone still opens with a swipe, anyone who picks it up can read your messages, open apps or change settings. Without an active screen lock, accidental taps in your pocket can also trigger calls or purchases. Setting up a Pattern, PIN or Password closes that gap and keeps the phone usable only for you.

Open
Notifications & Focus

Hide or Show Notification Content for Locked Apps

Locking an app on your Xiaomi phone stops others from opening it, but the notification banner can still show the full message text on the lock screen. That means a locked banking app or messenger can leak private content even while the app itself stays protected. Xiaomi lets you control notification previews separately for every app you have locked, without switching notifications off entirely.

Open
Network & Connectivity2

Change Preferred Network Type

If your phone shows no or barely any 4G/LTE signal in certain spots, calls drop and data stalls even though older 3G or 2G networks are still available nearby. The Preferred network type setting decides which mobile network your SIM tries first, and the wrong choice can leave you stuck searching for a signal instead of connecting to one that actually works.

Open
Notifications & Focus2

Show or Hide Lock Screen Notification Content

If your Xiaomi phone shows full message text on the lock screen, anyone picking up the phone can read private notifications before it is even unlocked. If content stays hidden instead, you only see that something arrived without knowing what it says or who sent it. This behavior is controlled by a single notification format setting in MIUI, separate from each app's own notification permissions.

Open
System & Settings2

Assign Google Assistant to the Power Button

On some Xiaomi phones a short press of the Power button opens the power menu instead of Google Assistant, even though full screen gesture navigation is active. This happens because the button shortcut for Google Assistant sits in a separate settings section and stays off by default. Without enabling it, you still need the home button gesture or voice command to wake the Assistant.

Schedule Power On/Off

If you keep forgetting to switch your Xiaomi phone off at night or want it ready and running before you even reach for it in the morning, pressing the power button every time gets old fast. MIUI includes a built-in scheduler that turns the device on and off at fixed times you define, with support for daily repetition or custom days. Once set up, the phone handles the switching on its own, without any manual input.

Open
Calls & Messages2

Sort Contacts by First or Last Name

If your Xiaomi contact list feels out of order, it usually comes down to whether the Contacts app is sorting entries by first name or last name. This becomes a real problem when you are searching for someone by their surname but the list is alphabetized by given name instead. The rule that controls this sits in one setting inside the Contacts app.

Notifications & Focus2

Focus & Shoot: Turn On or Off

If tapping the screen on your Xiaomi camera fires the shutter right away instead of just setting focus, Focus & shoot is switched on. Some people rely on this two-tap workflow to keep the phone steady, while others get accidental photos while they are still framing the shot.

Manage the Personal Dictionary

If your keyboard keeps autocorrecting a name, brand term, or slang word you actually want to type, MIUI's personal dictionary is the setting that controls this behavior. Without an entry there, the keyboard falls back to its built-in wordlist and ignores your preferred spelling or shortcut for longer phrases.

Turn Autofill Service On or Off

If login fields on your Xiaomi phone stay empty or a browser keeps offering saved passwords you never asked for, the Autofill service is likely misconfigured. This system feature decides whether apps and browsers can pull addresses, payment details or passwords into forms automatically. Switching providers or turning the service off changes what gets filled in and which app holds that data.

Document Scanner Shortcut: Enable or Disable

If the camera keeps popping up a scan icon every time you point it at a sheet of paper or a presentation slide, the Document scanner suggestion is active. Some people find this shortcut useful for quickly digitizing paperwork, others just want the extra button gone from the viewfinder.

Open
Network & Connectivity2

Turn On/Off Wi-Fi Calling

Weak signal at home, underground, or in a concrete building often causes dropped calls on a Xiaomi phone, even when Wi-Fi shows full bars. Wi-Fi calling routes voice calls through your wireless network instead of the mobile network, but only works if your carrier actually supports it. If the toggle is missing from your SIM settings, an unsupported plan or outdated carrier profile is usually the reason.

Turn Off User Experience Program

If usage statistics keep syncing quietly in the background on your Xiaomi phone, the User Experience Program is likely still active. This service sends anonymous usage data from your device to Xiaomi to help refine products and features. Since it is not possible to verify exactly what data leaves your device, disabling this option is the safer choice.
