Turn an Alarm On or Off

Alarms you already set on your Xiaomi phone stay stored even after you switch them off, but the toggle in the Clock app is easy to miss. If an alarm keeps ringing when you do not need it, or stays silent when you want it active, the switch next to the entry is probably in the wrong position. This affects your wake-up routine and any reminders you set up in MIUI.

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.

Turn Screen Cast On or Off

If your Xiaomi phone won't mirror to a TV or monitor, the built-in Cast feature might be turned off, or your phone and screen aren't on the same Wi-Fi network. Screen Cast behaves differently from many third-party mirroring apps, since playback usually stops the moment you turn off the display. That makes it easy to mistake a disabled toggle for a broken connection.

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.

Turn Emergency Alerts On or Off

If your Xiaomi phone keeps buzzing with Amber Alerts or severe weather warnings you never signed up for, the Emergency alerts feature is likely still active in the background. Some people want the opposite and need extreme threat notifications, vibration and voice alerts to actually get through. Either way, the switch sits in a security menu that is easy to overlook.

Set Up Switch Access

If tapping the touchscreen is difficult or impossible, everyday tasks like opening apps, scrolling, or typing on a Xiaomi phone can become a real barrier. Switch Access lets people with motor disabilities control the phone through one or more external switches instead of direct touch. These switches connect over USB or pair via Bluetooth and take over selection, scrolling, and text entry.

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.

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.

Add a Time Stamp to Photos

Photos taken with your Xiaomi phone often show no date or time, making it hard to prove exactly when a picture was captured. This is controlled by the Watermark option inside the Camera app, which stays off by default on most MIUI devices. Without it enabled, every shot leaves the gallery without any timestamp overlay.

Apps & Installation2

Set an App Timer to Limit App Usage

Some apps quietly eat hours of your day without you noticing, especially social media or games that keep notifications pulling you back in. On Xiaomi phones there is no built-in reminder that tells you when an app has crossed a healthy usage limit. Digital Wellbeing lets you assign a daily time budget per app so it pauses itself once that budget runs out.

Notifications & Focus2

Turn Battery Drain Notifications On or Off

If your Xiaomi phone keeps popping up alerts about fast battery drain, or you never get one and expect to, this setting is the reason. Battery drain notifications warn you when an app or background process burns through power faster than normal. Left enabled, unrelated background tasks can trigger these alerts more often than you would like.

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.

Security & Privacy2

Change Home or Lock Screen Theme

If your Home screen, Lock screen, and app icons suddenly look inconsistent after switching themes, MIUI applied only part of the new theme's assets. This happens when a saved theme only covers some elements, like Lock screen and System, but skips Icons. Picking the wrong theme ('Classic' vs 'Limitless') or a corrupted download can also leave icons untouched while wallpapers change.

Open
Photo, Video & Media2

Turn Camera Grid Lines On or Off

If your photos keep coming out tilted or the horizon never lines up straight, you are probably shooting without any framing guide. Xiaomi's camera app can overlay a 3x3 grid that helps you keep verticals upright and place the horizon on a clean line. Without it, minor tilts are easy to miss on a small screen and only show up later when you check the shot on a bigger display.

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

Turn Notification Badges On or Off Per App

A red dot keeps sitting above an app icon even after you have opened every message inside it. On Xiaomi phones this badge is a separate switch from the notification itself, so muting an app does not always remove the counter. If the dot never clears, or shows up for an app you barely use, the badge toggle for that specific app is still turned on.

Network & Connectivity2

Change SIM PIN

The PIN that comes preset on a new SIM card is rarely one you can memorize, and typing the wrong code repeatedly locks the card. On Xiaomi phones you can swap it for a PIN you actually remember, but the option sits a few menus deep under network security settings rather than in the main lock screen settings.

Wi-Fi Assistant: Select Best Networks Automatically

If your Xiaomi phone keeps switching away from a weak Wi-Fi network without asking, Wi-Fi assistant is likely doing that for you. Once every nearby network drops in signal, it can also fall back to mobile data on its own, which can use up your data plan faster than expected. This automatic switching can also cause interruptions during video calls or downloads.

Turn Do Not Disturb On or Off

When Do Not Disturb is active on your Xiaomi phone, calls get an instant busy signal and every notification stays silent, even for messages you actually want to hear. Many people leave it on by accident after enabling it for a meeting or at night, since MIUI does not always show a clear reminder that it is still running. Checking the current status and switching it off takes just a few taps in Sound & vibration settings.

Change Device Name

If your Xiaomi phone still shows up under its model number when you scan for Bluetooth devices or connect to a hotspot, that is the default device name at work. It makes picking your phone out of a list of nearby devices harder, especially if you own more than one Xiaomi device. MIUI lets you replace that generic label with a name you actually recognize.

Unhide an Album in Gallery

If a photo album you hid earlier is missing from Gallery, it is not deleted - it just sits in a separate hidden section. Xiaomi keeps hidden albums out of the main view until you unhide them again, and each album needs to be restored on its own.

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
Storage & Backup2

Change Time Format

If your Xiaomi phone shows time in a format you did not choose, MIUI is likely following your system language setting automatically. This means the clock can jump between 12-hour and 24-hour display whenever you change language or region. You can lock the format manually so it stays consistent no matter what language MIUI is set to.

Change Webpage Text Size in Mi Browser

If text on websites looks too small to read comfortably or too large and forces constant scrolling in Mi Browser, the webpage display size is set to the wrong level. Xiaomi phones offer five separate font sizes for browsing, independent from the system font size in your general settings. Switching to a different level fixes cramped or oversized text on every site you visit.
