Turn Accessibility Menu Shortcut On or Off
If a small floating icon suddenly shows up in the bottom right corner of your screen on your Xiaomi phone, the Accessibility menu shortcut has been switched on. This icon opens a panel with accessibility actions and does not change how the rest of the phone works. You can turn it on or off depending on whether you actually need those accessibility tools.
Turn Full Screen Mode On or Off for Specific Apps
When an app stretches its interface awkwardly across the full display or crops out buttons at the edges, full screen mode is usually forcing content into the wrong aspect ratio. Xiaomi lets you switch this behavior on or off separately for each installed app. The system also flags which apps handle full screen well and which ones do not, but that recommendation does not always match what you actually want.
Notch Display per App
If one app stretches its content behind the notch while another leaves a black bar around it, the per-app notch setting is likely mismatched with that app's layout. This shows up mostly in games or video apps that were not built with a notch in mind. The fix depends on a setting Xiaomi lets you configure separately for each installed app.
Add a Keyboard Language
Typing in a second language on your Xiaomi phone turns into a mess of red underlines and wrong autocorrect suggestions when the keyboard only knows one language. Messages, emails, and notes in that language become slower to write because every word gets flagged or swapped for something else. The built-in keyboard supports multiple languages at once, but only if you add them manually first.
Change Default Dialer App
If you install a new phone or call app on your Xiaomi device, calls may still open in the standard MIUI Dialer instead of your preferred app. This happens because MIUI keeps its own dialer set as default until you switch it manually in the app settings. Third-party dialer apps from the Play Store only take over once you assign them as default there.
Add a Fingerprint
If you can only unlock your Xiaomi phone with one specific finger, you probably registered just a single fingerprint during setup. MIUI lets you store several fingerprints so both your left and right hand work for unlocking or confirming payments. Each saved fingerprint can also get its own name, which helps when the device is shared with family.
Hide and Show Apps on the Home Screen
If an app keeps showing up on your home screen even though you do not want it visible, MIUI can hide it completely as long as App lock is turned on. Without App lock active, the option to hide apps simply does not appear in the menu. Once hidden, an app only reappears after you unlock it with your password or pattern.
Mark All Messages as Read
When unread badges pile up across several conversations in the Messages app, tapping into each thread just to clear the counter gets tedious fast. On MIUI there is a faster way to clear every unread marker at once, without opening every single chat.
Turn Auto-capitalization On or Off
If your Xiaomi keyboard keeps capitalizing letters you want lowercase - like usernames, code snippets, or crypto addresses - auto-capitalization is likely running in the background. It automatically capitalizes the first letter after a period or new sentence, which speeds up regular typing but gets in the way for technical text. The setting sits inside the keyboard's text correction options, not the main system settings.
Enable the Number Row on the Keyboard
If you only get digits by long-pressing the letter keys on your Xiaomi keyboard, the number row is switched off. That is the default state on the MIUI keyboard, so every digit needs an extra long-press instead of a single tap. A dedicated setting adds a permanent row of numbers above the letters, which speeds up typing passwords, codes or addresses.
Turn On/Off Call Forwarding
Calls landing in voicemail even though your phone never rang usually means call forwarding is already active in the background. On many Xiaomi phones the network sets forwarding for 'busy', 'unanswered' and 'unreachable' cases by default, so you might not notice it until a call disappears. Each of these forwarding rules can be switched on or off separately, or redirected to a different number entirely.
Move Photos or Videos into an Album
Photos and videos pile up in one long Gallery feed until finding a specific shot means endless scrolling. When you try to sort them into an album, Gallery stops you with a choice between moving or copying the file, and picking the wrong option can leave duplicates behind or remove the original from where you expected it.
Manage the Personal Dictionary
If your keyboard keeps autocorrecting a name, brand term, or slang word you actually want to type, MIUI's personal dictionary is the setting that controls this behavior. Without an entry there, the keyboard falls back to its built-in wordlist and ignores your preferred spelling or shortcut for longer phrases.
Double Tap to Wake or Sleep Screen
Waking your Xiaomi phone only works by pressing the power button, and double-tapping the display does nothing. This happens when 'Double tap to wake or turn off screen' is switched off in the lock screen settings, so a quick glance at the clock or notifications requires a full button press instead.
Switch Between Navigation Buttons and Gestures
If your Xiaomi phone shows on-screen Back, Home, and App Toggle buttons but you expected full-screen swipe gestures - or swipes stopped registering and buttons appeared instead - the system navigation mode has switched. This setting decides whether MIUI runs on three buttons or edge-to-edge gestures, and mixing up the active mode leads to missed taps or swipes that do nothing.
Set a Default Home Screen
Tapping the home button always drops you on the wrong panel, especially if you keep several home screens or widget pages active on your Xiaomi phone. MIUI lets you pin one specific screen as the default target, but this setting is easy to miss and gets reset after a launcher change or update. Without it, the home button just returns to whichever screen you last viewed.
Force Stop an Unresponsive App
When an app keeps running in the background and refuses to close normally, closing the recent apps card often does nothing. Force stopping shuts the process down completely, but it can also interrupt saved data or active downloads.
Assign a Custom Ringtone to a Contact
If every incoming call sounds the same, you have to check the screen to know who is calling before you pick up. On Xiaomi phones, the default ringtone applies to all contacts unless you override it manually for specific people.
Change Preferred Network Type
If your phone shows no or barely any 4G/LTE signal in certain spots, calls drop and data stalls even though older 3G or 2G networks are still available nearby. The Preferred network type setting decides which mobile network your SIM tries first, and the wrong choice can leave you stuck searching for a signal instead of connecting to one that actually works.
Show or Hide Lock Screen Notification Content
If your Xiaomi phone shows full message text on the lock screen, anyone picking up the phone can read private notifications before it is even unlocked. If content stays hidden instead, you only see that something arrived without knowing what it says or who sent it. This behavior is controlled by a single notification format setting in MIUI, separate from each app's own notification permissions.
Bedtime Mode: Turn On or Off
If your Xiaomi phone keeps buzzing with notifications late at night or the screen stays distractingly bright while you try to fall asleep, Bedtime mode is probably not set up yet. This feature is supposed to mute the device and dim the colors automatically, but only if you pick the right trigger - a fixed schedule or charging at night. Choosing the wrong option is the usual reason it never kicks in when you actually need it.
Lock Background Apps
If a chat app or timer keeps getting killed the moment you switch away from it, MIUI's battery management is likely closing it in the background. On many Xiaomi phones the old trick of locking an app from the recent apps overview no longer works. The lock option now lives inside the Security app instead.
Turn Quick Ball On or Off
If the floating navigation bubble is missing from your Xiaomi screen edge, you probably switched off Quick Ball at some point. This shortcut button gives fast access to actions like locking the screen, capturing a screenshot, or switching between recent apps without touching the physical buttons. When it disappears or starts blocking games and videos, it usually comes down to one setting hidden inside Additional settings.
Turn an Alarm On or Off
Alarms you already set on your Xiaomi phone stay stored even after you switch them off, but the toggle in the Clock app is easy to miss. If an alarm keeps ringing when you do not need it, or stays silent when you want it active, the switch next to the entry is probably in the wrong position. This affects your wake-up routine and any reminders you set up in MIUI.
