Allow or Deny Picture-in-Picture Access per App
If a video keeps floating over your screen after you switch away from an app, or a floating window refuses to disappear while you're typing a message, picture-in-picture is active for that app. Some apps use this floating window aggressively even when you just want the screen back to yourself, while others lose the ability to keep playing video in the background because the permission got switched off. This setting controls exactly which apps are allowed to open that overlay window on your Xiaomi phone.
Clear RAM and Storage
If your Xiaomi phone feels sluggish or storage keeps filling up, junk files, app cache, and rarely used apps are often the cause. MIUI includes a built-in cleanup tool that clears RAM and storage in one pass, but what actually gets removed depends on which categories you select before confirming.
Turn On/Off Pop-up on Keypress
If every letter you tap on your Xiaomi keyboard flashes up in a small preview bubble, typing can feel slower and the screen looks cluttered. This preview comes from a keyboard setting called Popup on keypress, and it can get in the way when you type quickly in Messenger, WhatsApp or any other app. You can switch it on or off directly in the keyboard settings on your phone.
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.
Restart the Xiaomi Smartphone
If apps on your Xiaomi phone start lagging, background downloads get stuck, or the interface feels sluggish after days of uptime, a restart usually clears the problem. MIUI keeps processes and cached data running in the background, and over time this can slow down the whole system. A clean reboot forces MIUI to close every open app and rebuild its memory from scratch.
Add a Second Face Unlock Profile
If Face Unlock keeps failing because you wear glasses, a mask, or switch up your look, one stored face often is not enough. Xiaomi lets you register a second face profile so the sensor recognizes both appearances without asking for your PIN every time. Without this second entry, the phone falls back to Pattern, PIN or Password whenever your look does not match the saved data.
Turn Off Battery Saver Automatically After Charging
If Battery saver stays active even after your Xiaomi phone finishes charging, it keeps throttling performance and dimming the screen longer than needed. MIUI can switch Battery saver off on its own once the battery reaches a set charge level, so you don't have to remember to disable it by hand every time you unplug the charger.
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.
Turn a Keyboard On or Off
A new keyboard downloaded from the Play Store does not automatically show up next to Gboard on your Xiaomi phone. Until you switch it on in the input settings, it stays hidden from the language switcher and typing keeps defaulting to the old keyboard. This usually happens with third-party layouts, handwriting keyboards, or apps installed after the initial setup.
Change Wallpaper on Home Screen
Tapping and holding the home screen only gives you a handful of preset wallpapers to pick from. If you want a specific photo from a particular folder set as your background, that shortcut alone won't get you there.
Send Photos and Videos via Bluetooth
Sending a photo or video from your Xiaomi phone to a paired device sometimes stalls right after you tap Share, or the target device never shows up in the list. This usually comes down to picking the wrong sharing option or Bluetooth pairing not being active. The steps below use MIUI's file sharing menu, which works the same for pictures, videos and most other file types.
Snooze App Notifications
When a chat app or delivery tracker keeps buzzing during a meeting, muting it completely isn't always what you want. MIUI lets you pause a single notification for a set time instead of turning it off for good. This keeps the alert coming back later without touching the app's notification settings.
Configure Individual System App Settings
When Security, Messages, or Camera on your Xiaomi phone keeps auto-updating or asking for permissions you never approved, a hidden per-app toggle in System app settings is usually the cause. Each preinstalled MIUI app, from Calendar to Recorder, carries its own switches for updates, notifications, and background data that do not show up on the regular app info screen. Finding the right toggle for the right app is the only way to fix the behavior without disabling the whole app.
Record a Video with the Camera App
If the Xiaomi Camera app only shows photo mode when you open it, video recording is often just one swipe away and easy to miss. Some users also get confused about which button starts, pauses, and stops a recording, since the shutter button changes function depending on the mode. This mix-up leads to accidentally recorded clips or missed footage.
Set Up a Portable Wi-Fi Hotspot
If your Xiaomi phone still hands out a hotspot name and password nobody chose, other people nearby can guess it or connect without permission. A weak default SSID also makes it harder to spot your own hotspot among several devices in the same room. Setting a custom name and password fixes both problems and keeps the connection under your control.
Switch Between Old and New Control Center Style
If your Xiaomi phone still shows the older two-panel layout after an update, or you miss that classic view after switching to the newer simplified overview, the display style does not change on its own. It sits behind a separate setting that many people never open. Notifications and quick toggles stay mixed together until you pick the layout you actually want.
Turn Off Wi-Fi and Bluetooth Scanning for Location
Even with Wi-Fi and Bluetooth switched off, your Xiaomi phone can still scan nearby networks and devices to sharpen its location fix. Apps with location permission trigger this background scanning automatically, keeping your radios active more often than expected. If you want tighter control over when your phone searches for networks, the scanning setting needs to be adjusted separately from the Wi-Fi and Bluetooth toggles.
Battery Saver: Extra Power Optimization Options
If Battery saver is switched on but your Xiaomi phone still lights up the screen for every notification, the standard saver mode is not doing its full job. Always-on display can also keep draining power even while Battery saver is active. Two extra toggles sit outside the main Battery saver screen and control exactly this behavior.
Fix Fisheye Distortion in Ultra Wide Shots
Ultra wide shots on your Xiaomi phone sometimes bulge at the edges, making straight lines look curved like a fisheye lens. This happens because the wide field of view stretches objects near the corners of the frame. The camera app can correct this automatically, but the setting is easy to overlook.
Back Up Phone Data to Google Drive
If your Xiaomi phone gets reset, lost or swapped for a new one, contacts, messages and app data disappear unless a backup exists somewhere else. MIUI has a built-in option to save that data to Google Drive, but the toggle sits buried in the general settings and is easy to miss until you actually need it.
Switch to Scientific Calculator Mode
You open the Calculator app on your Xiaomi phone expecting only basic math, but functions like sine, cosine, tangent, square roots or Pi are nowhere to be found. Many users assume the app simply lacks these tools, when in fact they are hidden behind a display mode that most people never trigger. Without knowing the trick, you end up switching to a third-party app for calculations your phone already supports.
Turn On App Lock
If anyone can open your banking, messaging, or gallery apps just by unlocking your phone, sensitive content stays exposed. Xiaomi phones include a separate app-level lock that adds a second layer of protection on top of your screen lock. Setting it up wrong, or skipping the fingerprint option, often leaves some apps unprotected.
Mark Contact as Favorite
If a contact you call or message often gets buried in a long list, you probably haven't set it as a favorite yet. Favorites move straight to the top of the Contacts app and speed up dialing from the Phone app. It's a quick toggle, but easy to miss since it's tucked inside the contact detail view.
Show Emojis in the Symbols Keyboard
On Xiaomi phones the symbols keyboard can display your most recently used emojis for quicker access, but that suggestion strip stays hidden by default. The Mi keyboard needs this behavior turned on separately before recent emojis appear next to the symbols and numbers.
