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.

Rename a Contact Group

A contact group on your Xiaomi phone keeps the name you gave it when you first created it, even after you add or remove members over time. If that label no longer fits, MIUI lets you edit it without deleting the group or losing its contacts. Default groups like Family, Colleagues or Friends are locked and cannot be renamed.

Turn Emergency Location Service (ELS) On or Off

If first responders cannot pinpoint your position during an emergency call or text, Emergency Location Service on your Xiaomi phone may be switched off. This feature sends your current GPS position automatically whenever you dial an emergency number, but it only works if the setting is active and your wireless carrier supports it. Some users disable it by accident while adjusting location permissions, which delays help in a real emergency.

Security & Privacy2

Set Up a Privacy Protection Password

Anyone who unlocks your Xiaomi phone can still open apps like Gallery, Notes, or File Manager without a second check, exposing personal photos or documents. The screen lock protects the whole device but not individual apps, which is where a separate privacy password comes in.

App Location Permission Settings

If a Xiaomi app keeps showing the location icon even when you are not actively using it, its permission is probably set to allow access all the time. That drains battery and can expose more data than the app actually needs. You can review and change this setting for every installed app individually.

Restore Deleted Photos or Videos from the Recycle Bin

Deleted a photo or video on your Xiaomi phone and now need it back? The Gallery app does not erase files right away - they sit in a hidden trash folder for a limited time before they disappear for good. Missing this window means the memory is gone permanently.

Save a Webpage in Mi Browser

Closing a browser tab often means losing an article for good, especially without a stable connection to reload it later. Mi Browser includes a built-in save function, but most people only notice the screenshot option and overlook the HTML and PDF alternatives. Each format behaves differently once you try to reopen, edit, or share the saved page again.

Network & Connectivity2

Save Location Info for Photos and Videos

Photos and videos from the Xiaomi camera arrive without any location tag, so sorting vacation shots by place later only works if you remember the trip yourself. That happens because the camera option for saving location info sits switched off out of the box. Turning it on lets the Camera app attach GPS coordinates to every photo and video you capture.

Apps & Installation2

Blur Effect for App Previews

When you swipe through recent apps on your Xiaomi phone, the preview thumbnails can show account balances, chat messages or other personal details in plain sight. MIUI lets you blur individual app previews so text and layout become unreadable at a glance. The setting works per app, which means it is easy to forget for apps you add later, such as a new banking or messaging app.

Apps & Installation2

Allow or Deny Apps to Modify System Settings

Some apps on your Xiaomi phone quietly hold permission to change system settings like brightness, do-not-disturb or notification behavior, even after you stopped using them. If a random app is toggling display or sound settings on its own, this hidden permission is usually the cause. You can review and revoke it for individual apps without affecting others.

Open
Accessibility2

Turn on TalkBack

Once TalkBack starts running, every tap on the screen gets read aloud instead of performed right away, which throws off anyone who did not expect the phone to switch to gesture-based navigation. This screen reader is essential for blind or low-vision users, but a stray touch inside the Accessibility menu can turn it on by accident too, changing how the whole interface reacts to touch. Knowing exactly where the toggle sits helps you switch it on deliberately or turn it back off if the phone suddenly stops responding to normal taps.

Calls & Messages

Set Default Account for New Contacts

If you keep getting asked which account to save a new contact to on your Xiaomi phone, MIUI has no default target set. This happens when Google Account, Mi Account, and one or both SIM cards are all active on the same device. Every save then triggers a manual account pick, which slows down quick contact entry.

Switch Between Browser Tabs

Comparing prices or articles across several websites gets confusing fast if you cannot jump between open pages in Mi Browser. On Xiaomi phones the tab overview is easy to miss, so people end up closing and reopening pages instead of switching between them directly.

Apps & Installation

Set a Button Shortcut for Split Screen

Opening split screen through the recent apps menu takes several taps and only works if you can find the small split-screen icon on the app card. If your phone uses button navigation instead of gestures, there is a faster way: a long press on one of the navigation buttons can trigger split screen directly.

Calls & Messages2

Add Contacts to a Group

Groups on your Xiaomi phone stay empty until you actually assign contacts to them. You can add people either from a single contact's profile or from inside the group itself, and mixing up the two methods is where most confusion starts. Knowing which screen controls group membership saves you from re-adding the same contact twice.

Open
Language & Input2

Change the Default Keyboard

Installed a new keyboard app on your Xiaomi phone but typing still opens Gboard? MIUI keeps the previous keyboard active until you manually switch the default under Languages & input. Without that step, the new keyboard stays listed but never takes over text fields.

Network & Connectivity2

Share Wi-Fi Password via QR Code

Typing out a long Wi-Fi password for every visitor gets tedious, especially with random letter-number combos. Xiaomi phones can turn your current network credentials into a scannable QR code instead. Anyone with a camera can then join the network without you dictating a single character.

Open
Security & Privacy

Rename Face Data

If you have saved more than one face profile on your Xiaomi phone, for example a regular look and one with glasses, every entry shows up under the same generic label in the Face unlock settings. Without a custom name it is hard to tell which profile matches which appearance, especially when you only want to manage or delete one of them.

Open
Apps & Installation2

Create or Remove Dual Apps

Running two WhatsApp or Facebook accounts on one phone usually fails because those apps only allow a single login at a time. Dual apps gets around that by cloning the app into a second icon with its own data and notifications, fully separate from the original. Without setting this up, you are stuck logging out and back in every time you want to switch accounts.

Open
Calls & Messages2

Turn MMS Read Receipts On or Off

If contacts can see the moment they read your MMS messages, or you cannot tell whether your own texts got opened, the read receipt option is likely misconfigured on your Xiaomi phone. This setting works separately from standard SMS delivery reports and needs its own toggle inside the messaging app. On Dual SIM devices, each SIM line can carry a different receipt setting, which often explains why the behavior seems inconsistent between conversations.

Open
Photo, Video & Media2

Switch Between Front and Rear Camera

Selfies on a Xiaomi phone often need extra light, and the display flashes white to fake a camera flash for the front lens. If you are not sure where the switch control sits or why the screen behaves this way, jumping between front and rear camera during a quick shot or video call gets slower than it should. This affects both the Camera app and any third-party app that uses the same camera controls.

Open
Accessibility2

Turn Off TalkBack on Xiaomi

If your Xiaomi phone reads out everything you tap and single taps only select items instead of opening them, TalkBack is active. This screen reader changes how touch works across the whole system, which makes normal navigation confusing if you never meant to turn it on.

Open
Notifications & Focus2

Turn On/Off Ascending Alarm Volume

If your Xiaomi alarm starts at full volume and jolts you awake instead of easing you into the morning, the ascending volume option is likely switched off. Some users prefer the opposite: a gentle ramp-up feels too quiet to wake them at all. Either way, this sits in a separate alarm setting that many people never notice.

Open
Notifications & Focus

Hide Notifications for Hidden Apps

If a hidden app on your Xiaomi phone still shows message previews on the lock screen or in the notification shade, anyone glancing at your phone can read what is inside. This happens because App lock only hides the app icon by default, not its incoming notifications. You can decide separately whether alerts from locked apps stay invisible until you open and unlock them.
