Set Start of Week in Calendar
If your calendar always opens on a Sunday even though you expect Monday to be the first column, the app is just following the region setting on your phone. This mismatch makes weekly planning confusing, especially when you compare dates with colleagues or family using a different week layout. A quick setting inside the Calendar app fixes the view for good.
Turn Call Barring On or Off
If your Xiaomi phone keeps racking up charges while roaming abroad, or you need to stop all incoming or outgoing calls for a while, call barring is the setting responsible. Unlike silencing a contact or using Do Not Disturb, call barring blocks calls at the network level and requires a password to change. Getting the wrong option enabled can also cut off calls you actually want, like international or roaming numbers.
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.
Hide or Show Notification Content for Locked Apps
Locking an app on your Xiaomi phone stops others from opening it, but the notification banner can still show the full message text on the lock screen. That means a locked banking app or messenger can leak private content even while the app itself stays protected. Xiaomi lets you control notification previews separately for every app you have locked, without switching notifications off entirely.
App Lock Timing
If App lock keeps asking for your PIN every time you switch briefly between apps, the delay is probably set too tight. Xiaomi lets you choose whether protected apps lock the instant the screen turns off, right after you leave the app, or after a short grace period. Picking the wrong option means either constant re-entry or apps staying unlocked longer than you want.
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.
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 the Full Screen Indicator (Gesture Bar)
With gesture navigation active on a Xiaomi phone, a thin bar stays visible at the bottom of the screen at all times. It sits on top of apps, videos and games, and some people find it distracting during full-screen use. This line is a system indicator tied to gesture navigation, not a bug.
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.
Sort Contacts by First or Last Name
If your Xiaomi contact list feels out of order, it usually comes down to whether the Contacts app is sorting entries by first name or last name. This becomes a real problem when you are searching for someone by their surname but the list is alphabetized by given name instead. The rule that controls this sits in one setting inside the Contacts app.
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.
Document Scanner Shortcut: Enable or Disable
If the camera keeps popping up a scan icon every time you point it at a sheet of paper or a presentation slide, the Document scanner suggestion is active. Some people find this shortcut useful for quickly digitizing paperwork, others just want the extra button gone from the viewfinder.
Turn Off User Experience Program
If usage statistics keep syncing quietly in the background on your Xiaomi phone, the User Experience Program is likely still active. This service sends anonymous usage data from your device to Xiaomi to help refine products and features. Since it is not possible to verify exactly what data leaves your device, disabling this option is the safer choice.
Set Battery Saver for Individual Apps
If one app drains your battery fast while another stops sending notifications on time, a single phone-wide power saving mode will not fix both problems. Xiaomi lets you assign a separate battery plan to each app instead of forcing every app into the same restriction level. Picking the wrong option for an app can either waste battery or delay important alerts.
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.
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.
Reset Mi Browser Settings
If Mi Browser keeps loading a search engine you never picked, autofill won't clear, or saved passwords and history pile up without an obvious way to clean them individually, restoring the browser to its defaults fixes all of that in one step. This wipes personal settings and locally stored browsing data together, so it helps most when smaller fixes like clearing cache alone did not solve the problem.
Set Up Screen Lock with Pattern, PIN or Password
If your Xiaomi phone still opens with a swipe, anyone who picks it up can read your messages, open apps or change settings. Without an active screen lock, accidental taps in your pocket can also trigger calls or purchases. Setting up a Pattern, PIN or Password closes that gap and keeps the phone usable only for you.
Turn Off Mobile Data When Device Is Locked
If your Xiaomi phone keeps burning through mobile data even while sitting locked in your pocket, a background data setting is likely still active. MIUI can cut mobile data automatically once the screen locks, but the delay before that happens is often left on a setting that does not match how you use the phone. That gap is what causes messages, emails or app updates to keep syncing long after you stopped looking at the screen.
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.
Change Keyboard Theme (Language & Input)
If the Gboard keyboard on your Xiaomi phone still shows the default gray background, the theme setting has never been switched. This only changes the visual layout - colors, gradients or picture backgrounds - and has no effect on autocorrect or typing speed. The key borders can also be turned on or off separately from the overall theme.
Set Swipe-from-Edge Action in Mi Browser
Swiping in from the left or right edge of the screen in Mi Browser normally sends you back or forward a page, and that can get in the way if you actually meant to switch tabs. Xiaomi lets you reassign this edge gesture in Mi Browser or turn it off completely if it keeps triggering by accident.
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.
