Show or Hide Carrier Name on Lock Screen
If your Xiaomi lock screen shows the SIM carrier name under the clock, a MIUI status bar setting is behind it. Some people want that text gone for a cleaner lock screen or extra privacy, while others lose it after a reset and want it back. Either way, the toggle sits in one specific settings screen and is easy to miss.
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.
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.
Turn On Automatic Network Selection
If your Xiaomi phone stays locked to a single carrier and won't reconnect after a SIM swap or a trip abroad, automatic network selection is probably switched off. This setting normally lets MIUI scan for and pick the strongest available network on its own, so having it disabled means you have to search and connect manually every time you lose signal. On dual SIM phones each card has its own toggle, so fixing one slot does not automatically fix the other.
Desktop View in Mi Browser
Mobile sites on your Xiaomi phone often hide buttons, filters, or entire menus that only show up in the desktop layout. Mi Browser squeezes every page into a phone-friendly view by default, which helps scrolling but can block tools like advanced editors or full navigation bars. Switching to the desktop version brings those missing elements back without needing a computer.
Mount SD Card
If you tapped Eject SD card or safely removed the card from your Xiaomi phone, the storage disappears from your file manager and apps stop saving to it. MIUI keeps the card unmounted until you tell it to reconnect, even after a reboot in some cases. Photos, downloads, and app data meant for the card get redirected to internal storage instead.
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.
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.
Filter Call History
When your Xiaomi call log fills up with dozens of entries, finding a specific missed or outgoing call turns into scrolling work. The Phone app on MIUI stores every call in one long list without separating calls by type or SIM card by default. A built-in filter option sorts the log so you only see the calls that matter.
Set Up a VPN Connection
If a website, streaming service, or company network blocks your current connection, a VPN reroutes your traffic through an encrypted server and hides your real location. Without one, your provider and any public Wi-Fi you join can log everything you send. MIUI does not create VPN profiles on its own, so you need a working server address and login details ready before you connect.
Adjust Screen Timeout Duration
If your Xiaomi display turns off after a few seconds or stays lit far longer than you expect, the sleep timer is set to the wrong value. This setting decides how long the screen stays active before it locks, and it has a direct effect on battery drain and how often you have to unlock the phone.
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.
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.
Set Up Fingerprint Unlock
Setting up fingerprint unlock on a Xiaomi phone only works if you already have a Pattern, PIN, or Password configured, and MIUI asks for it before it lets you enroll a finger. If you cannot remember that unlock code, the fingerprint menu will not let you proceed at all. Many users also get confused about how many fingerprints they can add and what each one can be used for.
Auto-answer for Incoming Calls
If calls on your Xiaomi phone connect themselves before you even touch the screen, Auto-answer is likely switched on in the background. This MIUI feature can pick up every call after a set delay, or only when a Bluetooth headset is connected. Missing that toggle means you lose the chance to reject a call while it is still ringing.
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.
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.
Change Home or Lock Screen Theme
If your Home screen, Lock screen, and app icons suddenly look inconsistent after switching themes, MIUI applied only part of the new theme's assets. This happens when a saved theme only covers some elements, like Lock screen and System, but skips Icons. Picking the wrong theme ('Classic' vs 'Limitless') or a corrupted download can also leave icons untouched while wallpapers change.
Set the Default Media Volume Level
Videos, music, and games on your Xiaomi phone start way too loud or too quiet, and pressing the Volume buttons only helps once something is already playing. That happens because Media volume runs on its own channel, separate from ringtone and notification levels in MIUI.
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.
Add Account in Calendar App
If appointments from your Google or work account never show up in the Xiaomi Calendar app, only one account is usually linked to it. Calendar only displays events for accounts you have added yourself, so a new work email or a second Google account stays invisible until you connect it. This is also why events vanish after switching phones or resetting the calendar app.
Change Camera Picture Quality
If your camera storage fills up fast or photos take too long to share, the picture quality setting in the MIUI camera app is often the reason. Xiaomi's camera defaults to a high resolution that produces large files, even when you only need a quick snapshot. Switching between High, Standard, and Low lets you balance sharpness against file size for each situation.
Turn Notification Badges On or Off Per App
A red dot keeps sitting above an app icon even after you have opened every message inside it. On Xiaomi phones this badge is a separate switch from the notification itself, so muting an app does not always remove the counter. If the dot never clears, or shows up for an app you barely use, the badge toggle for that specific app is still turned on.
