Change App Lock Password Type
If you set up App lock on your Xiaomi phone with a pattern and now want something faster or more secure, you are not stuck with that choice. The lock type you picked during setup can be swapped for a PIN or password at any time, without disabling App lock first.
Manage Device Administrator Apps
An app you want to uninstall on your Xiaomi phone refuses to go away, or a widget keeps nagging you about admin permissions. Device administrator apps get elevated rights to change security settings or wipe data remotely, which is exactly what blocks a normal uninstall. Turning off that permission is usually the fix before the app can finally be removed.
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.
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.
Export Contacts as a VCF File
Switching to a new phone or just backing up your address book can be tricky when the Contacts app on your Xiaomi phone does not offer a simple 'transfer' button. Instead, contacts leave the device as a VCF file, and picking the wrong storage location or account often means the file cannot be found afterward. Knowing where the export lands makes the difference between a working backup and a lost contact list.
Turn On/Off Auto-Update
If your Xiaomi phone keeps installing system updates overnight without asking, or you never get notified when a new MIUI version is ready, the auto-update setting is likely working against you. Some users want updates to install by themselves while they sleep, others prefer full control before anything changes on the device. This setting decides which of the two happens.
Turn Best Photo Marks On or Off
If your Gallery keeps flagging one photo out of a burst as the best shot, MIUI is comparing similar images and tagging the sharpest or best-exposed one automatically. Some users find this helpful for sorting large photo batches, others just want a clean gallery without extra labels. The setting controls whether this comparison runs at all.
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.
Dark or Light Theme for the Phone App
If the Phone app keeps showing a bright white call screen while the rest of your Xiaomi runs in Dark mode, the dialer has its own theme setting separate from the system. This mismatch usually happens because the app theme was never linked to System default, or it got reset after an update. It affects the call screen, contact list and dial pad, not just the notification bar.
Share a Contact via Message or App
Retyping a phone number into a text message often introduces errors, especially with long international formats. On Xiaomi phones, the Contacts app lets you send a person's saved details directly through messaging or email without typing anything manually. This keeps every field intact and avoids typos on both sides.
Delete Photos or Videos from Gallery
Storage on your Xiaomi phone fills up fast once photos and videos pile up in the Gallery app. Many users don't realize they can select several items at once instead of deleting them one by one. This guide covers the exact steps to clear out unwanted media quickly.
Show Notification Content Only After Face Unlock
Sensitive notification text sometimes appears on the Xiaomi lock screen before Face unlock has actually confirmed your identity. This happens because the notification preview and the face verification step are controlled by two separate settings on MIUI. Once linked, message content only unlocks after your face data matches.
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.
Quick Ball Shortcuts and Behavior Settings
If the floating Quick ball only opens one fixed app or keeps popping up during video playback, its behavior settings are still on default. MIUI lets you change the trigger gesture, auto-hide rules and screen position, but these options sit outside the shortcut list and get overlooked easily.
Manage Displayed Calendar Accounts
If every linked account shows up in the Calendar app at once, work meetings and private appointments end up mixed together in one view. This happens because the Calendar app displays all synced accounts by default, with no separation between personal and work calendars. You can turn individual accounts on or off without removing them from the device.
Enable Keyboard Dark Theme in Battery Saver
If your Xiaomi keyboard stays bright white even after battery saver kicks in, the automatic dark theme switch for the keyboard is turned off. This setting is separate from the general dark mode toggle and only reacts to the power-saving state of the phone. Without it, the keyboard ignores battery saver and keeps burning extra power on OLED screens.
Change Press-and-Hold Shutter Button Function
On Xiaomi phones, holding down the shutter button in the Camera app usually triggers a burst shot instead of a single photo. If you actually want continuous autofocus or a locked focus point for a tricky shot, that burst behavior gets in the way. MIUI lets you swap this hold action to Focus or Record video 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.
Clear the Whole Call History
When missed, dialed, and received calls pile up on your Xiaomi phone, scrolling through the list to find one number gets tedious fast. Deleting entries one at a time barely makes a dent if you actually want a clean call log. MIUI offers a single action that wipes the entire history at once, and once it's gone, it's gone for good.
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.
Add a City to World Clock
Your Xiaomi phone only shows the time for your home region, and comparing time zones means switching apps constantly. The World Clock widget can hold several cities at once, but the option to add one sits inside a menu that is easy to overlook. Removing a city later works differently too, since it needs a long-press instead of a simple delete button.
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.
Enable or Disable Google Assistant via the Home Button
Holding down the virtual home button on your Xiaomi phone launches Google Assistant automatically, even when you only meant to go back to the home screen. If that accidental trigger bothers you, or you actually want the shortcut and it is not working, the setting sits in a spot most people never check.
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.
