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.
Change App Lock Password Type
If you set up App lock on your Xiaomi phone with a pattern and now want something faster or more secure, you are not stuck with that choice. The lock type you picked during setup can be swapped for a PIN or password at any time, without disabling App lock first.
Turn Speak Passwords On or Off for TalkBack
When TalkBack reads your password out loud while you type it, anyone nearby can hear sensitive login data. On Xiaomi phones with MIUI, this happens because the Speak passwords option inside TalkBack is turned on by default. Switching it off keeps entered characters silent, though you lose the audio confirmation that a password was typed correctly.
Turn On/Off Emergency SOS
If your Xiaomi phone fires off an emergency text every time you grab it too fast, Emergency SOS is likely reacting to five quick presses of the power button. The feature sends your location and, if you choose, a summary of your last hour of call activity to selected contacts. Turning it off - or setting it up properly first - stops accidental alerts and unwanted location shares.
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.
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screen and on the lock screen isn't always what you'd like it to say, especially if your provider's branding is long or outdated.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.
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 Lock: Lock or Unlock Apps
Anyone who picks up your Xiaomi phone can open sensitive apps like banking, messaging or gallery without extra protection beyond the screen lock. App Lock adds a second barrier for individual apps, separate from your device PIN or pattern. Without it enabled, apps stay accessible the moment the phone itself is unlocked.
Fingerprint Unlock for App Lock
If a locked app on your Xiaomi phone keeps asking for the app lock password even though your fingerprint sensor works everywhere else, fingerprint unlock for App lock is probably switched off. This setting lets you skip the PIN or pattern entry for individual apps and confirm access with your finger instead. Without it enabled, MIUI falls back to the password every time you open a protected app.
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.
Fingerprint Scan for Privacy Password: Enable or Disable
If your fingerprint unlocks the Privacy password screen, anyone with your fingerprint can bypass the extra PIN or password that protects hidden apps and locked content. That shortcut is convenient, but it removes a second layer of protection some people rely on. Whether you want that convenience or prefer to keep the password entry mandatory depends on how the phone is used.
Pin a Conversation
If an important chat keeps sliding down your conversation list on a Xiaomi phone, new messages from other contacts push it out of view. The Messaging app sorts threads by recent activity, so a conversation without fresh replies eventually disappears from the top. Pinning keeps that specific chat visible regardless of how much new activity happens elsewhere.
One-Handed Keyboard Mode
Typing with one thumb on a large Xiaomi screen often means missing keys on the far side of the keyboard. The stock layout stretches across the full display width, so you end up stretching your thumb or shifting your grip with every message. Xiaomi's keyboard settings can shrink and pin the whole layout to the left or right edge instead.
Manage App Permissions with the Permission Manager
If you're unsure which apps can reach your camera, microphone or location on your Xiaomi phone, permissions granted at install time often go unnoticed afterwards. Over weeks several apps quietly keep background access to sensitive functions with no obvious place to check it. The permission manager under Privacy protection lists this access per function and per app, so you can spot anything that looks off.
Lock Home Screen Layout
If icons keep shifting position every time you delete an app or accidentally shake your phone, MIUI is still rearranging empty spaces on its own. Locking the layout stops that automatic reshuffling and keeps every icon exactly where you placed it.
Stay on Lock Screen After Face Unlock
If your phone jumps straight to the home screen after face unlock, you lose the chance to glance at notifications or widgets on the lock screen first. Other users want the opposite and prefer to land on the home screen right away without an extra tap. This behavior comes from a single toggle hidden inside the Face unlock settings on your Xiaomi phone.
Manage Device Administrator Apps
An app you want to uninstall on your Xiaomi phone refuses to go away, or a widget keeps nagging you about admin permissions. Device administrator apps get elevated rights to change security settings or wipe data remotely, which is exactly what blocks a normal uninstall. Turning off that permission is usually the fix before the app can finally be removed.
Allow or Deny Face Unlock When Screen Lights Up
If your Xiaomi phone unlocks itself just because the screen turned on for an incoming message or notification, Face unlock is reacting to every wake event instead of a deliberate unlock attempt. This can expose notification content or apps to anyone glancing at the display. The setting controlling this behavior sits inside Face unlock security options and is easy to miss.
Mi Browser Privacy and Security Settings
If Mi Browser keeps remembering passwords or search history you would rather not store, the built-in privacy controls are usually still on their default state. Autocomplete, personalized services, and security warnings can each expose more data than expected once you start browsing. Adjusting these toggles one by one gives you control over what Mi Browser saves and shares.
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.
Data Usage Warning on Lock Screen
If you blow through your mobile data plan before the billing cycle ends, you probably only find out when the carrier sends a throttling notice. Xiaomi phones can flag this earlier, but the lock screen warning for data usage is off by default on most devices. Without it enabled, you only see usage numbers if you open the Security app yourself.
Remove a Stored Fingerprint
If a fingerprint still unlocks your Xiaomi phone after you sold it, handed it to someone else, or just registered a bad scan, that print needs to go. MIUI stores several fingerprints under one name, so it is easy to remove the wrong one by mistake. Deleting a print always asks for your unlock pattern, PIN or password first, which trips up people who only remember using their finger.
Turn On/Off Incognito Mode in Mi Browser
If Mi Browser keeps saving your search history and open tabs even though you wanted a private session, Incognito mode is probably switched off. Once active, the tab icon shows a small mask and the background turns dark purple, but many users never notice the toggle or find it again after closing the app. Without it enabled, every page you visit stays logged in your browsing history.
