Delete an Alarm
If your Xiaomi phone keeps ringing at a time you no longer need, an old alarm is probably still sitting in the Clock app. Alarms pile up quickly once you set them for one-off events like flights or workouts, and they rarely get removed afterward. A cluttered alarm list also makes it harder to spot the one alarm you actually rely on every morning.
Change SIM PIN
The PIN that comes preset on a new SIM card is rarely one you can memorize, and typing the wrong code repeatedly locks the card. On Xiaomi phones you can swap it for a PIN you actually remember, but the option sits a few menus deep under network security settings rather than in the main lock screen settings.
Change Notification Sound
When every app on your Xiaomi phone plays the same generic chime, spotting an important message in a stack of notifications gets tricky. MIUI lets you pick a different tone per notification type, and if you run two SIM cards you can even split the sound by line. The tricky part is finding where this setting actually lives, since it is buried a few taps below the general Sound menu.
Restore a Local Backup
If you deleted an app or lost data on your Xiaomi phone, you don't need a full factory reset to get it back. MIUI keeps local backups separate from Google and Xiaomi Cloud backups, and picking the wrong one often leaves apps or settings missing. Knowing which backup type actually contains your data saves time before you start the restore.
Schedule Dark Mode Automatically
Switching dark mode on and off every day by hand gets tedious, especially when you only want it active at night. Xiaomi phones can handle this automatically, but the scheduler sits right next to the regular dark mode switch and is easy to miss. Without setting a start and end time, the display keeps whatever theme you last picked instead of changing on its own.
Change the Time Zone Manually
If your Xiaomi phone keeps switching its time zone whenever you travel or connect to a different carrier network, automatic time zone detection is the cause. This network-based setting overrides any manual change you make until you turn it off. Once you know where that toggle sits, you can lock in a fixed time zone yourself.
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.
Turn On/Off Wi-Fi Calling
Weak signal at home, underground, or in a concrete building often causes dropped calls on a Xiaomi phone, even when Wi-Fi shows full bars. Wi-Fi calling routes voice calls through your wireless network instead of the mobile network, but only works if your carrier actually supports it. If the toggle is missing from your SIM settings, an unsupported plan or outdated carrier profile is usually the reason.
Turn Do Not Disturb On or Off
When Do Not Disturb is active on your Xiaomi phone, calls get an instant busy signal and every notification stays silent, even for messages you actually want to hear. Many people leave it on by accident after enabling it for a meeting or at night, since MIUI does not always show a clear reminder that it is still running. Checking the current status and switching it off takes just a few taps in Sound & vibration settings.
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.
Set Up a Proxy Server for Wi-Fi
If your network admin or workplace requires traffic to run through a specific server, a plain Wi-Fi connection on your Xiaomi phone will not route it correctly. Without a configured proxy hostname and port, apps either fail to connect or bypass the required server entirely. This affects browsing, app updates and anything that depends on that network policy.
Filter Contacts by Account
If your contact list mixes phone numbers, WhatsApp entries, and other synced accounts, finding the right person gets messy fast. MIUI keeps every synced account in one long list by default, which makes Calls and Messages harder to scan. A built-in filter lets you narrow that view down to only the account you actually need.
Turn Bluetooth On or Off
If a Bluetooth headset, speaker, or car kit will not pair with your Xiaomi phone, Bluetooth is often still switched off or was never fully enabled after a restart. The Quick Settings toggle can also drift out of sync with the actual radio state, which leaves paired devices unable to reconnect until you check the setting directly.
Unhide an Album in Gallery
If a photo album you hid earlier is missing from Gallery, it is not deleted - it just sits in a separate hidden section. Xiaomi keeps hidden albums out of the main view until you unhide them again, and each album needs to be restored on its own.
Change SIM Card Name
Two SIM cards from the same carrier look identical on your Xiaomi phone, so it is easy to grab the wrong one for a call or a mobile data session. MIUI shows a generic carrier label for each slot by default, which does not tell you which SIM is your personal number and which one is for work or travel. Giving each SIM card its own name in the phone settings clears up that confusion for good.
Turn Dual Clock On/Off on Lock Screen
After switching the region on a Xiaomi phone, a second time suddenly shows up on the lock screen next to the main clock. This happens because MIUI detects a time difference between your set region and your current location or SIM, and the Dual clock feature reacts automatically. You can switch it off entirely or change which region the second clock refers to.
Assign a Photo to a Contact
When a contact shows only initials or a plain avatar during calls and messages, no photo has been linked to that contact yet. MIUI lets you attach an existing picture from your gallery instead of only allowing a new snapshot. Without that link, incoming calls and chat threads stay visually anonymous even if the contact already has a name and number saved.
Vibration in Silent Mode: Turn On or Off
When you switch a Xiaomi phone to Silent, it still buzzes for every incoming call or message by default. If you want the device completely quiet without any buzzing on the table, you need a separate toggle beyond the ringer switch itself.
Add or Remove Bookmarks in Mi Browser
Losing track of a website you visited last week is common once it drops out of your browser history. Bookmarks fix this by saving the page permanently until you decide to remove it. The catch is that many Xiaomi users don't know where the bookmark list actually lives inside Mi Browser, so saved pages get forgotten or accidentally deleted.
Disable Automatic Video and Image Downloads in Mi Browser
If your mobile data disappears fast while browsing on your Xiaomi phone, Mi Browser might be pre-loading videos and images before you even tap them. This automatic download feature speeds up page loading but quietly eats into your data plan. Turning it off puts you back in control of what actually gets downloaded.
Change Display Size
If text and icons on your Xiaomi phone look too small or too cramped, the Display size setting is usually the cause. It scales both the interface and the font size together, which can push app shortcuts around on your home screen until you rearrange them.
Create a Folder on the Home Screen
If your home screen is cluttered with dozens of app icons, grouping them into folders keeps things organized. On MIUI, folders are created by dragging one app icon onto another, the same drag-and-drop gesture you might know from a PC desktop or other Android phones. You need at least two apps ready to combine before a folder actually appears.
Turn Off App Lock
If Xiaomi's App lock keeps asking for a PIN, pattern or fingerprint before certain apps open, and some apps seem to have vanished from your app drawer, the lock feature is still active in the background. Turning it off releases every protected app at once and brings previously hidden apps back into view.
SMS Delivery Reports Setting
Not sure if a text message actually reached the other person? Xiaomi phones can show a status report for every SMS you send, but the switch for it sits deep inside the Messages app and is easy to overlook. With the setting off you get no confirmation at all, even when the message went through without issues.
