Turn Color Inversion On or Off
If your Xiaomi phone suddenly shows a black background with white text everywhere, or photos and videos look like a photo negative, Color inversion is likely switched on. This accessibility feature swaps colors system-wide, including in apps, galleries, and the camera preview, which can make the phone look broken until you know where to turn it off.
Turn Floating Notifications On or Off
Every pop-up banner that slides over your Xiaomi lock screen or current app comes from the floating notifications feature, and not every app should get that permission. If a messaging app keeps interrupting your screen with banners while a quieter app never shows up at all, the per-app floating notification setting is usually the reason.
Manually Add an APN
If mobile data drops out or MMS messages will not send on your Xiaomi phone, the access point name (APN) supplied by your carrier might be missing or wrong. This entry is normally created the first time you insert a SIM card, but a factory reset, a new SIM, or a carrier update can wipe it out. Without a correct APN, the phone shows full signal but cannot actually load data.
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.
Focus & Shoot: Turn On or Off
If tapping the screen on your Xiaomi camera fires the shutter right away instead of just setting focus, Focus & shoot is switched on. Some people rely on this two-tap workflow to keep the phone steady, while others get accidental photos while they are still framing the shot.
Turn Autofill Service On or Off
If login fields on your Xiaomi phone stay empty or a browser keeps offering saved passwords you never asked for, the Autofill service is likely misconfigured. This system feature decides whether apps and browsers can pull addresses, payment details or passwords into forms automatically. Switching providers or turning the service off changes what gets filled in and which app holds that data.
Enable Reader View in Mi Browser
Long Wikipedia entries or news articles often mix text with ads, sidebars and menus that crowd a phone screen. Mi Browser has a reader view that strips a page down to just the article text and images. If the option seems to be missing on a particular page, it usually depends on how that page is built.
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.
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.
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.
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.
Turn Google Play Protect On or Off
If your Xiaomi keeps blocking app installs from outside the Play Store, or you get repeated malware warnings for apps you know are safe, Google Play Protect is usually behind it. The feature scans every app before and after installation and can flag legitimate apps as risky. You can check its current status and switch the scanning behavior directly from the security settings.
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.
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.
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.
Restrict Floating Notifications in Do Not Disturb
If your Xiaomi phone keeps popping up banners while Do Not Disturb is active, incoming alerts are still showing as floating notifications instead of staying silent. The messages themselves are not lost, they simply arrive quietly in the background, but the pop-ups still interrupt whatever you are doing. This setting decides whether MIUI shows those floating banners while DND is on.
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.
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.
Volume Buttons Function for Camera
Pressing the volume buttons in the Xiaomi camera app triggers the shutter or a countdown timer by default, not zoom. If you want the buttons to handle something else while framing a shot, the assignment can be changed in the camera settings. Right now only two options are available for this shortcut.
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.
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.
Allow Calls During Do Not Disturb
If Do Not Disturb mode is silencing calls you actually want to receive, a call filter is deciding who gets through and who gets blocked. Xiaomi phones let you choose between allowing calls from anyone, only contacts, only starred contacts, or nobody at all while the mode is active. Missed calls from family or work contacts usually trace back to this exact setting being set too strictly.
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.
Set a Default Launcher on Xiaomi
Installed a new launcher on your Xiaomi phone but the home screen still opens with the MIUI launcher? Android keeps using the previous launcher until you tell the system which app should manage your home screen, widgets and app shortcuts. Without changing the default app assignment, your new launcher stays installed but inactive.
