Auto-download Updates via Mobile Data
If your Xiaomi phone keeps pulling system updates in the background while you are off Wi-Fi, mobile data usage can climb fast without warning. MIUI treats update downloads as automatic once a new version is detected, and a separate toggle decides whether mobile data counts as an allowed source for that download. Switching it off limits update downloads to Wi-Fi only, which matters if you are on a limited plan.
Snooze App Notifications
When a chat app or delivery tracker keeps buzzing during a meeting, muting it completely isn't always what you want. MIUI lets you pause a single notification for a set time instead of turning it off for good. This keeps the alert coming back later without touching the app's notification settings.
Set Up a Portable Wi-Fi Hotspot
If your Xiaomi phone still hands out a hotspot name and password nobody chose, other people nearby can guess it or connect without permission. A weak default SSID also makes it harder to spot your own hotspot among several devices in the same room. Setting a custom name and password fixes both problems and keeps the connection under your control.
Select Network Manually
When you travel abroad and your phone keeps hanging on a weak carrier, automatic network selection is usually the cause. MIUI picks a network by signal priority, not by actual reception quality, so calls drop and data stalls even though a stronger carrier is available nearby. Switching to manual selection lets you pick that carrier yourself instead of waiting for the phone to reconnect.
Edit and Rearrange Quick Settings
If the toggle you need most sits at the bottom of the control center or is missing entirely, you have to scroll or swipe further every time you want to switch it on. MIUI lets you add, remove and reorder these quick settings tiles, but the edit option is easy to miss if you have never opened it before.
Allow or Deny Do Not Disturb Access for Apps
When an app suddenly enables Do Not Disturb on its own, or a call app keeps muting notifications you actually want to see, a hidden system permission is usually behind it. On Xiaomi phones, individual apps can request permission to switch Do Not Disturb on or off, and that access is not always obvious from the app itself. Checking which apps hold this permission helps you regain control over your notifications.
Delete an Album in Gallery
Deleting an album on your Xiaomi phone also deletes every photo and video still stored inside it. This catches a lot of people off guard when they just wanted to tidy up their Gallery app and end up losing media they meant to keep. Knowing which albums are safe to remove and which ones hold originals is key before you tap delete.
Add New Browser Tabs
Closing your current page every time you want to check something else in Mi Browser gets old fast. If you cannot find a way to browse two pages at once without losing your place, the tab feature in Mi Browser solves that without extra apps.
Fingerprint Shutter: Enable or Disable
If your Xiaomi phone snaps a photo every time you rest a finger on the fingerprint sensor while the Camera app is open, the fingerprint shutter option is turned on. Some users only notice this after an accidental shot ends up in the gallery, others want to turn it on deliberately for a steadier one-tap trigger. Either way, the setting lives inside the Camera app itself, not in the general phone settings.
Set a Timer in the Clock App
Setting an alarm just to catch the end of an eBay auction wastes a reminder slot and still leaves you guessing when to check back. The Timer function in the Clock app on your Xiaomi phone counts down a fixed period and alerts you the moment it is over, without touching your alarm list. Many users overlook this tool because it sits next to the alarm and stopwatch tabs and rarely gets used.
Turn Personalized Ad Recommendations On or Off
If ads on your Xiaomi phone feel oddly tied to your recent searches or app activity, Personalized ad recommendations is the setting behind it. Switching it off does not lower how many banners you see, it only stops MIUI from matching them to your interests and usage data.
Email Guests From a Calendar Event
If an appointment reminder alone is not enough, guests often miss details or forget the event entirely. MIUI Calendar lets you send everyone attached to an event a custom email, but the app pre-selects all added guests automatically. Checking that list before sending prevents the message from going to the wrong people.
Add a New Contact
Saving a new phone number on a Xiaomi device sometimes feels confusing because the Contacts app hides extra fields like birthday, address or company behind a single Add button. Many users only enter a name and number, then wonder later why the birthday never shows up in the calendar. The trick is knowing which fields to expand before you save the entry.
Power Button Ends Call Setting
Ending a call on a Xiaomi phone usually means tapping the red hang-up button on screen, which is awkward one-handed or when the display is hard to reach. MIUI has a hidden accessibility toggle that lets you end calls with the power button instead, but it is turned off by default and easy to miss in the settings.
Turn a SIM Card On or Off
On a dual SIM Xiaomi phone, calls or texts sometimes keep arriving on a line you no longer want to use, or you want to silence one number without pulling the physical card out. MIUI lets you deactivate a SIM slot completely, which stops all calls, messages and mobile data on that line until you switch it back on.
Install an App from the Play Store
Setting up a new Xiaomi phone often means hunting for the right way to add apps like WhatsApp, a cookbook, or a new game. Search results in the Play Store can show several similar-looking entries, so picking the correct one before tapping Install actually matters.
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.
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.
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.
Show or Hide Holidays in Calendar
If your Xiaomi calendar looks packed with public holidays you never asked for, real appointments and reminders get buried fast. This clutter often comes from a default setting that pulls in every regional or national holiday for your account. Turning that display on or off only takes a moment once you know where MIUI hides the switch.
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.
Change Home Screen Transition Effect
Swiping between home screen pages on your Xiaomi phone always triggers the same flat slide animation, even after you have customized icons and widgets. MIUI actually ships with several transition styles such as Crossfade, Cube or Cascade, but the option sits inside the home screen settings rather than the main display menu, so most people never find it.
Set Ringtone for Incoming Calls
When every incoming call on your Xiaomi phone uses the same generic tone, or a video calling app ignores your chosen sound completely, the default ringtone setting is usually the cause. Dual-SIM users often run into a second issue: one SIM plays the wrong tone because each line can carry its own ringtone. Both problems trace back to the same sound settings that MIUI applies system-wide.
