Allow or Block Display over Other Apps
When a chat bubble from Messenger or your Messages app refuses to pop up over other screens, the permission behind it is usually switched off. MIUI hides this setting under a different name than stock Android, which makes it easy to miss. Without it, apps can only notify you in the background instead of floating on top of whatever you are doing.
Allow Apps from Unknown Sources
Downloading an APK through the Mi Browser or a file manager on a Xiaomi phone and getting blocked at the install screen is common once MIUI tightens its unknown-sources rule. A single global switch no longer works — MIUI now asks you to approve each source app individually before it can install anything outside the Play Store. Until that specific app gets permission, every install attempt from it fails or shows a warning.
Turn Google Discover On/Off on the Home Screen
If the Info Assistant or Google Discover feed disappeared from your Xiaomi home screen, you probably stopped getting stock updates, news, or quick shortcuts. This panel sits on the leftmost home screen page and gets toggled through a hidden home screen setting, not through the Google app itself. Swiping all the way left and finding a blank page usually means it got switched off by accident.
Manage App Autostart Permissions
If certain apps keep draining battery overnight or notifications arrive late, MIUI's autostart permission might be blocking background services for that app. Autostart controls which apps can load background functions right after you power on your phone, not the app itself. Checking this setting helps you balance battery life against apps that need to stay ready in the background.
Change Default Messaging App
Texts land in one app while replies keep opening in another, or a new SMS app you downloaded from the Play Store never becomes the one that actually launches. This happens because MIUI keeps a fixed default assignment for messaging that does not update automatically when you install a new app. Until that assignment is changed manually, notifications and quick replies keep routing to the wrong app.
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.
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.
Remove App from Folder
When a folder on your Xiaomi home screen fills up with apps you barely touch, finding the one you actually use often becomes annoying. This happens a lot with apps like Messenger or WhatsApp, which start in a folder but end up needing a spot of their own once you rely on them daily. MIUI lets you pull an app back out without deleting anything.
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.
Set an App Timer to Limit App Usage
Some apps quietly eat hours of your day without you noticing, especially social media or games that keep notifications pulling you back in. On Xiaomi phones there is no built-in reminder that tells you when an app has crossed a healthy usage limit. Digital Wellbeing lets you assign a daily time budget per app so it pauses itself once that budget runs out.
Split Screen on Xiaomi Phones
Split screen lets you run two apps side by side on your Xiaomi phone, so you can chat while browsing or take notes while watching a video. MIUI offers more than one way to trigger it, and not every app supports it the same way. Knowing how it behaves helps you decide when it actually saves time.
Open Split Screen via Recent Apps
Switching back and forth between two apps constantly slows you down, especially when you need to compare content or copy information between them. On Xiaomi phones the Recent apps overview hides the option to run two apps side by side unless you tap and hold the right spot on the app card. Not every app supports this mode, and the shortcut disappears if you tap the wrong area.
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.
Restrict Mobile Data Usage for an App
If a Xiaomi phone burns through your data plan even though you barely open certain apps, background data access is usually the cause. By default every installed app can use mobile data and Wi-Fi without restriction. On dual-SIM phones this applies separately to each SIM slot, which makes it harder to spot which line is actually consuming the data.
Disable Navigation Bar Per App
Accidentally tapping the Back or Recents button during a full-screen game or video can pull you out of the app at the worst moment. On Xiaomi phones the on-screen navigation bar stays active by default even in apps that do not need it. MIUI lets you set this behavior per app instead of turning it off system-wide.
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.
Show Memory Status in Recent Apps
When you swipe up to check recent apps on a Xiaomi phone, the memory bar at the top sometimes just isn't there, leaving you without a quick read on free RAM. This indicator only reports live usage and does not close or manage background apps on its own. Without it turned on, you lose a fast way to judge whether your phone is actually running low on memory.
Clear App Data
When an app on your Xiaomi phone starts crashing, freezing, or throwing login errors, clearing the cache alone often does not fix it. Corrupted app data, broken login sessions or leftover settings can keep triggering the same error even after a cache clear. Wiping the app data resets it completely, though you will need to sign in again and reconfigure the app afterward.
Turn Off Suggestions in Recent Apps Menu
If your recent apps screen on a Xiaomi phone keeps showing extra tiles for Cleaner, Security scan, Deep cleaning or Manage Apps, a system suggestion feature is adding them automatically. This can make the app switcher feel cluttered and slower to scan through, especially if you only want to see your open apps.
Edit App Vault Shortcuts
If your App Vault on the Home screen still shows outdated app icons, or the shortcuts you actually use don't fit anymore, the list needs a manual update. Xiaomi's App Vault holds up to eight shortcuts from categories like Social Media, Entertainment, Security, or Tools, and MIUI never reorders or refreshes them on its own. You have to add, remove, or move each shortcut yourself.
Manage Updates for System Apps
If your Xiaomi phone keeps nagging you about system app updates - or stays silent when new versions are actually ready - the System apps updater settings are probably not set the way you want. MIUI lets you control whether update notifications show up, whether updates install automatically, and whether downloads run on Wi-Fi only or also over mobile data. Leaving these settings on default can mean unexpected data usage or missed fixes.
Set a Timer in the Clock App
Setting an alarm just to catch the end of an eBay auction wastes a reminder slot and still leaves you guessing when to check back. The Timer function in the Clock app on your Xiaomi phone counts down a fixed period and alerts you the moment it is over, without touching your alarm list. Many users overlook this tool because it sits next to the alarm and stopwatch tabs and rarely gets used.
Install an App from the Play Store
Setting up a new Xiaomi phone often means hunting for the right way to add apps like WhatsApp, a cookbook, or a new game. Search results in the Play Store can show several similar-looking entries, so picking the correct one before tapping Install actually matters.
Change Default Apps
If your Xiaomi phone keeps asking which app to use every time you open a song, a link, or a photo, no default app is set for that file type. MIUI stores these preferences per action, and once none is chosen, the selection prompt reappears every time you tap the file.
