Raise to Wake: Turn On or Off
If lifting your phone doesn't wake the screen, the Raise to wake feature is probably switched off. This setting decides whether MIUI turns on the display automatically when you pick up the phone, instead of you having to press the power button for a quick glance at the time or a notification.
Send MMS Message
Xiaomi Messages does not offer a separate MMS button, so it is easy to assume attachments go out as a normal text message. As soon as you add a photo, video, or .gif to a chat, the app switches the message to multimedia format automatically. If your carrier has MMS disabled or your mobile data is off, that message can silently fail to send.
Turn Camera Shutter Sound On or Off
Every photo on your Xiaomi phone triggers a shutter click, even in a quiet room or during a video call screenshot. The sound comes from the camera app itself and has nothing to do with your ringtone or notification volume, so muting the phone alone will not silence it.
Change Default Apps
If your Xiaomi phone keeps asking which app to use every time you open a song, a link, or a photo, no default app is set for that file type. MIUI stores these preferences per action, and once none is chosen, the selection prompt reappears every time you tap the file.
Set the Time Manually
If the clock on your Xiaomi phone keeps jumping back to the wrong hour right after you edit it, the Use network-provided time toggle is still active in the background. Xiaomi phones pull the time straight from your mobile network or Wi-Fi connection, so any manual change gets overwritten within seconds. That sync option has to be switched off first before a custom time will actually stick.
Set Default SIM Card for Outgoing Calls
Every time you dial a number, your Xiaomi phone pops up a menu asking which SIM card to use for the call. If you only ever tap the same option anyway, that extra confirmation step just slows down dialing. A fixed default SIM removes the prompt for good.
Reject an Incoming Call
If a call comes in at a bad moment on your Xiaomi phone, you don't have to answer it or wait it out. The red decline icon on the incoming call screen lets you dismiss it right away, but only if you swipe correctly. Miss the gesture and the call keeps ringing or gets answered by accident.
Rename a Fingerprint
Every fingerprint you add on a Xiaomi phone gets a generic label like Finger 1 or Finger 2, which makes no sense once you have three or four saved. If you cannot tell your thumb from your index finger in the list, renaming them is the only way to keep the Fingerprint unlock screen readable.
Set Autoclick Dwell Timing for a Mouse
If you control your Xiaomi phone with a connected mouse, clicking a tiny cursor button gets tiring fast. Autoclick (dwell timing) lets the phone register a click automatically once the pointer stops moving for a set time. The delay is adjustable, so a short dwell time can trigger accidental taps while a long one feels sluggish.
Save Photos and Videos to SD Card Automatically
If your Xiaomi phone keeps filling up internal storage even though a microSD card is inserted, the camera is probably still saving everything to the phone by default. New shots and clips pile up locally instead of moving to the card, which quickly triggers low-storage warnings.
Camera Modes Layout: Tab or Panel
Switching between Photo, Video, and other capture modes takes an extra tap when your camera app hides them behind a 'More' tab instead of a swipeable panel. This layout setting decides how the mode bar behaves at the bottom of the viewfinder, and the wrong choice can slow down quick mode changes while shooting. The option lives inside the camera app itself, not in the general phone settings.
Turn Off Display Animations
Menus and apps on your Xiaomi phone fade in and out with a noticeable delay, and swipe transitions feel slower than the actions behind them. This comes from a system-wide animation effect that MIUI applies to almost every screen change. On older or budget hardware, that extra motion can make the whole interface feel less responsive than it actually is.
Add a Print Service
If a print dialog on your Xiaomi phone shows no printer at all, no print service is registered in MIUI yet. Most phones only come with a driver for Epson devices, so printers from other brands stay invisible until you install their own service. Without that step, apps like a PDF viewer or browser can never send a job to your printer.
Change Password for a Saved Wi-Fi Network
If your router password changed, your Xiaomi phone still tries to connect with the old one and just shows Saved, not connected. This is common after a router reset or a switch to a new internet provider. You do not need to forget the network and start over, the saved entry can be updated directly.
Change Carrier Name in Status Bar
The carrier label at the top of your screen and on the lock screen isn't always what you'd like it to say, especially if your provider's branding is long or outdated. On dual SIM phones the same generic label often shows for both slots by default, which gets confusing when the two cards belong to different networks.
Turn Off the Content Feed in Mi Browser
If Mi Browser opens straight into a wall of YouTube clips, Facebook posts and random subscription suggestions instead of your homepage, the content feed is switched on. This feed pulls in recommended articles and videos every time you launch the app, which feels cluttered if you only want a plain start screen. You can switch it off or back on whenever you want.
Change the Google Backup Account
If your Xiaomi phone keeps backing up to the Google Account you used during setup, files and app data saved under a newer account never make it into the backup. This happens because MIUI locks in the original backup account and does not switch automatically once you add a second Google Account. You have to select the account manually before new backups use it.
Change System Language
If your Xiaomi phone ended up in a language you cannot read, or you simply want to switch after setup, you do not need to go through the activation wizard again. The system language lives in its own settings menu, separate from the one-time language screen you saw when you first turned on the phone. This also affects keyboard suggestions and how some apps display their text.
Auto-Fill Empty Home Screen Cells After Uninstalling Apps
When you uninstall an app on a Xiaomi phone, the empty cell it leaves behind can sit unused or the whole layout can shift, depending on one home screen setting. Most people never notice this toggle exists until their icons suddenly rearrange themselves. Knowing where it lives lets you decide whether gaps stay put or close automatically.
Turn One-handed Mode On or Off
If your Xiaomi phone feels too big to reach the top of the screen with one thumb, the built-in one-handed mode shrinks the whole display into a smaller window. Many users never find this option because it hides under Additional settings instead of the main Display menu. Without it enabled, you are stuck stretching or using both hands for every notification bar swipe or top-corner button.
Close All Tabs in Mi Browser
After a long browsing session in Mi Browser, the tab counter on your Xiaomi phone can climb to a number you never actually chose. Every open tab keeps running in the background, which slows down the browser and drains extra battery. Closing them one by one takes forever, but there is a faster way.
Set a Daily Mobile Data Usage Limit
A monthly data cap does not catch the one day you binge-watch or download something huge, and by the time the monthly warning fires the damage is done. On Xiaomi phones you can add a separate daily threshold so heavy usage gets flagged the same day it happens. You also decide whether MIUI just warns you or cuts mobile data automatically once the limit is hit.
Turn Screen Locking Sounds On or Off
Every time your Xiaomi phone locks or unlocks, a short click plays, and it keeps repeating as you use the device throughout the day. That sound comes from the Screen locking sounds option buried in the sound settings, not from notifications or Focus mode. It can be muted or restored in a few taps once you know where it hides.
Clear Speaker Sound Cleaner
If your Xiaomi phone's speaker sounds muffled or noticeably quieter than it used to, dust or lint trapped in the speaker grille is usually the reason. MIUI has a built-in tool that plays a short cleaning tone to help shake particles loose before you reach for compressed air or a pin.
