Remove a Linked Account
If chats, photos or documents suddenly disappear after cleaning up accounts on your Xiaomi phone, the sync connection for that account was likely removed rather than just logged out. Google, WhatsApp, Facebook and similar accounts all sit under the same accounts module, and removing one can wipe locally cached data tied to it. Knowing which account type you are touching matters before you tap confirm.
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.
Show or Hide Declined Calendar Events
Declined meeting invites disappear from the Xiaomi Calendar app by default, so you cannot see which appointments you turned down or check past responses. This happens because the toggle that controls declined-event visibility is switched off in the calendar settings. Depending on how your Google account syncs, hidden entries can also make your event history look incomplete.
Clear App Cache
If an app on your Xiaomi phone keeps crashing, freezing, or throwing error messages, leftover cache files are often the reason. Over time these temporary files pile up and can overlap or corrupt each other, causing an app to behave oddly even though nothing else changed. Clearing the cache removes that clutter without touching your saved data or settings.
Set Wi-Fi Hotspot Data Limit
If your mobile data plan drains fast whenever you share your Xiaomi phone's Wi-Fi hotspot with a laptop or tablet, an unlimited hotspot session is usually the cause. MIUI lets you cap the exact amount of data the hotspot can share and pick what happens once that cap is reached.
Set Up Unlock with Bluetooth Device
If your Xiaomi phone stays locked even though your paired Bluetooth accessory is nearby, the Unlock with Bluetooth device feature is probably still off. Once active, the phone unlocks automatically near that device and stays unlocked as long as the connection holds. This only works with Xiaomi's own Bluetooth accessories, not with third-party headphones or wearables.
Turn Global Icon Animations On or Off
If third-party app icons on your Xiaomi phone bounce or pulse every time you tap them, a system-wide animation setting is running in the background. Some people like the extra feedback, others find it distracting or feel it slows down the home screen. This setting controls the effect for all installed apps at once, not for a single icon.
Camera Delay-Timer
If your Xiaomi camera fires the shutter the instant you tap the button, group photos or selfies often turn out blurry or catch you mid-pose. MIUI has a built-in delay-timer for exactly this situation, but it sits hidden inside the camera menu instead of the main shooting screen. Without it, you only get a split second to get into position before the shot is taken.
Delete a Single SMS Message
Deleting a whole conversation wipes out every message in that thread, even the ones you still need. Sometimes you only want one text gone, like an old verification code or a message sent to the wrong person. On Xiaomi phones, single messages inside a conversation can be removed without touching the rest of the thread.
Unarchive a Conversation
Archived chats disappear from the main Messages overview on Xiaomi phones, which makes them easy to lose track of. If you archived a conversation by mistake or need to reply again, it stays hidden until you move it back manually. The message thread stays fully intact in the Archived folder, ready to be restored at any time.
Delete a Folder from the Home Screen
A folder that still holds one or two apps refuses to disappear no matter how often you tap on it. MIUI does not offer a direct delete button inside the folder itself, which confuses a lot of users. The trick lies in how you grab and move the folder icon, not in emptying it app by app.
Turn On/Off Screen Magnification
If icons, text or app menus stay too small even after adjusting the display size, the built-in screen magnifier can help. On Xiaomi phones this feature works as a temporary zoom you trigger with a gesture or a shortcut button, not as a permanent font size change. Many users enable it but then struggle to find the toggle again or accidentally leave it running in the background.
Keyboard Usage Statistics Sharing Toggle
If your Xiaomi phone keeps sending keyboard usage data to Google in the background, that's the 'Share usage statistics' option buried in the keyboard settings. This toggle controls whether typing patterns get reported for diagnostics, and it's on by default on most devices. Many users only discover it exists when checking their privacy settings after noticing unfamiliar data usage.
Uninstall an App
Old apps you never open still take up storage on a Xiaomi phone, and the app drawer gets crowded fast. Dragging an icon off the home screen sometimes only removes a shortcut instead of the actual app, which is confusing if the storage warning keeps coming back. Uninstalling deletes the app together with all its saved data permanently, so it helps to know exactly which tap does what before you remove several apps at once.
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.
Add a Bookmark to the Home Screen
If you keep opening Mi Browser just to reach one saved website, that link only lives in your bookmarks list, not on the home screen. Xiaomi phones do not turn a saved bookmark into a shortcut automatically, so you have to add that icon yourself. Without it, every visit means opening the browser, tapping Bookmark, and scrolling to find the right entry.
Delete an APN Entry
A wrong or duplicate access point can block mobile data or MMS on your Xiaomi phone, even after you switch carriers or SIM cards. If an old APN profile stays behind, the device sometimes keeps trying to use it instead of the correct one. Removing the unused entry clears up the confusion without touching your other network settings.
Camera Watermarks
The camera watermark stamps a small label into the lower-left corner of your photos, either a standard device signature or a text you choose yourself. It helps you mark ownership, keep track of the device a shot came from, or add a personal touch for photos you share or sell online. Turning it on or off changes future shots only, not photos already stored in your gallery.
Set a Default Calling SIM for a Contact
On a dual-SIM Xiaomi phone, calling a specific person always triggers the SIM prompt, even though you always pick the same card for that number. This happens because the contact has no fixed calling SIM assigned, so MIUI asks every time before dialing out.
Manage Notifications for Individual Apps
If one chatty app keeps popping up over whatever you're doing, or a messaging app reveals message previews on the lock screen when you'd rather it didn't, the fix isn't a single master switch. On Xiaomi phones, every app has its own notification behavior for sound, pop-ups, banners, and lock screen visibility. Without adjusting the right app individually, the annoying alerts keep coming back.
Restore Deleted Contacts from Trash Bin
Accidentally deleted a contact on your Xiaomi phone and now you cannot call or message that person? MIUI keeps removed contacts in a separate Trash folder before they disappear for good, so nothing is lost right away. You just need to find that folder before the 30-day window runs out.
Pair a Bluetooth Device
If your headset, earbuds, or speaker will not connect to your Xiaomi phone, the accessory usually needs to be paired first before Bluetooth can use it. Until pairing finishes, the phone will not list it as an active connection, so audio and calls stay on the built-in speaker.
Change Calendar View
If your Google Calendar app on Xiaomi always opens in Month view, finding today's appointments takes extra scrolling. The default layout does not match how you actually plan your day. Switching between Schedule, Day, 3-Day, Week and Month views fixes this without touching any system settings.
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.
