Calls & Messages2

SMS Delivery Reports Setting

Not sure if a text message actually reached the other person? Xiaomi phones can show a status report for every SMS you send, but the switch for it sits deep inside the Messages app and is easy to overlook. With the setting off you get no confirmation at all, even when the message went through without issues.

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.

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.

Open
Network & Connectivity2

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.

Open
Display & Home Screen2

Add a Home Screen Page

Running out of room for app icons on your Xiaomi home screen is a common problem once you install more than a handful of apps. Instead of stacking icons into folders, you can create a completely new home screen page and spread your apps across it. This works with a simple drag gesture and does not require any extra settings menu.

Open
Other2

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.

Open
Display & Home Screen2

Enable Dark Mode in Mi Browser

If Mi Browser still shows bright white pages after the sun goes down, the built-in night option is probably switched off. This setting dims both the browser interface and many web pages, which cuts glare and makes late-evening browsing easier on your eyes. It sits separately from the general system theme, so changing one does not automatically change the other.

Open
System & Settings2

Turn On/Off Gesture Confirmation

Swiping back or closing an app by accident during a full-screen game or a video can throw you straight out of the action. On Xiaomi phones with full-screen gesture control, this usually happens because gesture confirmation is turned off, so a single swipe is enough to trigger the action. Turning it on forces you to swipe twice before the gesture actually executes.

Open
Security & Privacy2

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.

Calls & Messages2

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.

Open
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.

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.

Open
System & Settings2

Set Snooze Time and Repetition

If your Xiaomi alarm keeps snoozing for too long or not often enough, the default snooze interval and repeat count are likely not adjusted to your needs. MIUI lets you fine-tune both values, but the option sits several menus deep in the alarm settings.

Remove a Member from a Contact Group

If a contact still shows up in a group even though you no longer want them there, the fix is not to delete the contact but to unlink them from that specific group. On Xiaomi phones this distinction confuses people because the removal option sits inside the group menu, not in the contact's own profile screen.

Delete an Event in the Calendar App

If your calendar is cluttered with old appointments you no longer need, deleting individual events keeps things readable. Once removed, an event is gone for good and cannot be restored. On some Xiaomi phones the built-in Calendar app is replaced by Google Calendar, which uses a slightly different menu.

Open
Display & Home Screen2

Custom Image on Always-on Display

If the pre-installed Always-on Display themes on your Xiaomi phone all look the same, you can swap them for a photo of your own. MIUI lets you pick any image from your gallery instead of the default clock designs. Once applied, you can still adjust the clock position, text color, and how battery or notification icons appear on top of your picture.

Open
Storage & Backup2

Clear RAM and Storage

If your Xiaomi phone feels sluggish or storage keeps filling up, junk files, app cache, and rarely used apps are often the cause. MIUI includes a built-in cleanup tool that clears RAM and storage in one pass, but what actually gets removed depends on which categories you select before confirming.

Open
System & Settings2

Turn On/Off Pop-up on Keypress

If every letter you tap on your Xiaomi keyboard flashes up in a small preview bubble, typing can feel slower and the screen looks cluttered. This preview comes from a keyboard setting called Popup on keypress, and it can get in the way when you type quickly in Messenger, WhatsApp or any other app. You can switch it on or off directly in the keyboard settings on your phone.

Open
Accounts & Cloud2

Turn Auto-Sync Data On or Off

If your Xiaomi phone burns through mobile data or drains battery faster than expected, background account synchronization is often the reason. This setting keeps your Google Account data, like contacts, calendar entries and photos, updated in the background at all times. Switching it off stops the drain immediately but also means new changes stop arriving until you sync manually.

Open
System & Settings2

Restart the Xiaomi Smartphone

If apps on your Xiaomi phone start lagging, background downloads get stuck, or the interface feels sluggish after days of uptime, a restart usually clears the problem. MIUI keeps processes and cached data running in the background, and over time this can slow down the whole system. A clean reboot forces MIUI to close every open app and rebuild its memory from scratch.

Open
Battery & Power2

Turn Off Battery Saver Automatically After Charging

If Battery saver stays active even after your Xiaomi phone finishes charging, it keeps throttling performance and dimming the screen longer than needed. MIUI can switch Battery saver off on its own once the battery reaches a set charge level, so you don't have to remember to disable it by hand every time you unplug the charger.

Open
Language & Input2

Turn a Keyboard On or Off

A new keyboard downloaded from the Play Store does not automatically show up next to Gboard on your Xiaomi phone. Until you switch it on in the input settings, it stays hidden from the language switcher and typing keeps defaulting to the old keyboard. This usually happens with third-party layouts, handwriting keyboards, or apps installed after the initial setup.

Open
Display & Home Screen2

Change Wallpaper on Home Screen

Tapping and holding the home screen only gives you a handful of preset wallpapers to pick from. If you want a specific photo from a particular folder set as your background, that shortcut alone won't get you there.

Network & Connectivity2

Send Photos and Videos via Bluetooth

Sending a photo or video from your Xiaomi phone to a paired device sometimes stalls right after you tap Share, or the target device never shows up in the list. This usually comes down to picking the wrong sharing option or Bluetooth pairing not being active. The steps below use MIUI's file sharing menu, which works the same for pictures, videos and most other file types.
