Enable or Disable Captions for Supported Apps
When captions do not appear during playback, or they show up in a style that is hard to read against light backgrounds, the caption settings on your Xiaomi phone are usually the reason. This affects apps that hook into the system-wide caption feature, not just the video player itself. Size, color, and background of the caption text can all be adjusted separately from whether captions are shown at all.
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.
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.
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.
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.
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 Second Space
If the second space on your Xiaomi phone still takes up storage or keeps showing up as a swipe option on your lock screen, removing it completely clears out that whole separate profile. Second space works like a second phone with its own apps, photos and accounts, so it does not disappear just because you stop using it. This guide covers removing it directly from the space settings, which works slightly differently than deleting it through device admin.
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.
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.
Change Select to Speak Voice Output
If Select to Speak reads text too slowly or sounds flat, the text-to-speech engine behind it is still running on its default speed and pitch. MIUI lets you fine-tune the speaking rate, voice pitch and language instead of leaving Select to Speak untouched. A wrong accent or a voice that talks too fast points to the same settings screen.
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.
Change Notification Shade Shortcut
On many Xiaomi phones the icon in the top right corner of the notification shade always opens Settings, even if you never use it there. If you pull down notifications dozens of times a day mainly to search for something, that shortcut is wasted space and slows you down.
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.
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.
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 Read in Background On or Off for Select to Speak
When Select to Speak keeps talking after you leave an app, the Read in background option is doing its job, but not everyone wants that. Xiaomi flags this feature as experimental, so it can behave inconsistently between MIUI versions and sometimes keeps narrating text you no longer need read aloud. Knowing where the toggle sits helps you decide whether the trade-off is worth it.
