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.
Enterprise Mode
If you spot Enterprise mode buried in your Xiaomi settings and have no idea what switched it on, you are not alone. The feature is built for companies that want to restrict which apps or websites an employee device can reach, and in some setups it can also report device activity back to an administrator. On a private phone that was never enrolled by a company, this toggle usually just sits there unused, which raises the question of what it is doing and whether it is safe to leave alone.
Set a Custom Watermark in the Camera App
If every photo automatically shows your device or camera model as a watermark, you might want your own text there instead. The Watermark settings inside the Camera app let you swap that default label for a personal signature, but the option sits a few taps deep in the menu. Once set, the custom text gets stamped on every new shot instead of the model name.
Turn Lock Screen Notifications On or Off
Hiding lock screen notifications on your Xiaomi phone keeps message content away from prying eyes, but it also means pop-up alerts stop appearing when the screen is locked. Instead you only see small icons in the status bar, so you have to unlock the phone to check what actually happened. This trade-off between privacy and quick alerts confuses a lot of users switching the setting for the first time.
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.
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.
Show or Hide Password Characters While Typing
On Xiaomi phones, every character you type into a password field flashes briefly on screen before turning into a dot. If you unlock accounts in public, on a video call, or while someone else can see your display, that brief character preview can expose your password to anyone nearby.
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.
Turn On/Off Auto Brightness
If your Xiaomi screen keeps getting brighter or dimmer without you touching anything, Auto Brightness is reacting to the light sensor. You can still drag the brightness slider manually while the function stays active, which often causes confusion about which setting is actually in control.
Turn Off Developer Options
If Developer options keeps popping up in your Xiaomi settings even though you only enabled it once for a quick fix, it usually just needs to be switched off inside its own menu. Leaving it active keeps USB debugging and other low-level toggles exposed, which can interfere with app checks or banking apps. Turning it off hides the whole menu again until you reactivate it through the hidden tap sequence.
Split Screen on Xiaomi Phones
Split screen lets you run two apps side by side on your Xiaomi phone, so you can chat while browsing or take notes while watching a video. MIUI offers more than one way to trigger it, and not every app supports it the same way. Knowing how it behaves helps you decide when it actually saves time.
Turn Automatic Date & Time On or Off
If your Xiaomi phone shows the wrong time after a trip or SIM swap, the automatic time sync is likely still active. Automatic date & time relies on network-provided time, which can lag or fail when signal is weak. Turning it off lets you set the clock manually instead.
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.
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.
Turn Tap Sounds On or Off
Every tap on a button, the Back key, or a menu item triggers a short click sound on your Xiaomi phone. If that noise gets distracting during calls, meetings, or at night, the Tap sounds setting is behind it and can be switched off just as quickly as it can be turned back on.
Turn On/Off Read Text on Images (Select to Speak)
When Select to Speak on your Xiaomi phone starts reading text from photos or the camera viewfinder out loud, the Read text on images option is active. Xiaomi flags this as an experimental function, so it can misread words, skip lines entirely, or lag behind what the camera actually shows. Knowing where to switch it off helps once the readouts cause more confusion than they solve.
Restrict Mobile Data Usage for an App
If a Xiaomi phone burns through your data plan even though you barely open certain apps, background data access is usually the cause. By default every installed app can use mobile data and Wi-Fi without restriction. On dual-SIM phones this applies separately to each SIM slot, which makes it harder to spot which line is actually consuming the data.
Turn Contact Sharing via Bluetooth On or Off
When you pair your Xiaomi phone with a car radio, the contact list sometimes stays empty even though the Bluetooth connection shows as active. That happens because MIUI keeps Contact sharing separate from the general Bluetooth toggle, so voice dialing and steering-wheel controls have no phonebook to pull from until you enable it. The same setting can also keep sharing your address book with a paired device after you no longer want it to.
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.
Set Touch & Hold Delay
If long-pressing an app icon on your Xiaomi home screen either opens the shortcut menu too fast by accident or takes too long to react, the touch and hold delay is set to the wrong stage. This timing controls how long you need to keep your finger down before a long-press action triggers, and it affects every control element that supports it, not just app shortcuts.
Search Bar in Notification Shade
Pulling down the notification shade on a Xiaomi phone sometimes shows an extra search field at the top that you never asked for, or the opposite happens and you want that shortcut back. This toggle sits in Mi Browser, not in the notification settings where most people go looking for it. Without knowing that, the option seems to be missing entirely.
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.
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.
