Turn Personalized Ad Recommendations On or Off
If ads on your Xiaomi phone feel oddly tied to your recent searches or app activity, Personalized ad recommendations is the setting behind it. Switching it off does not lower how many banners you see, it only stops MIUI from matching them to your interests and usage data.
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.
Turn On/Off Emergency SOS
If your Xiaomi phone fires off an emergency text every time you grab it too fast, Emergency SOS is likely reacting to five quick presses of the power button. The feature sends your location and, if you choose, a summary of your last hour of call activity to selected contacts. Turning it off - or setting it up properly first - stops accidental alerts and unwanted location shares.
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.
Download Videos via Mi Browser
Saving a video from Facebook, YouTube or Vimeo on a Xiaomi phone usually means installing a separate downloader app first. Mi Browser can skip that step, but only if you know where the download option for links is hidden in the profile menu. Without it, a pasted video link just opens for streaming instead of saving to your storage.
Turn Camera Shutter Sound On or Off
Every photo on your Xiaomi phone triggers a shutter click, even in a quiet room or during a video call screenshot. The sound comes from the camera app itself and has nothing to do with your ringtone or notification volume, so muting the phone alone will not silence it.
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.
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.
Turn Front Camera Mirroring On or Off
Selfies taken with your Xiaomi front camera often look flipped compared to how other people actually see you, especially when text or logos appear reversed in the background. This happens because MIUI mirrors the preview and, on many devices, the saved photo to match what you see in the viewfinder. The mirroring setting controls whether your final shot keeps that flipped look or saves a true-to-life version.
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.
Change Carrier Name in Status Bar
The carrier label at the top of your screen and on the lock screen isn't always what you'd like it to say, especially if your provider's branding is long or outdated. On dual SIM phones the same generic label often shows for both slots by default, which gets confusing when the two cards belong to different networks.
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.
Rename a Gallery Album
Album names like Camera, Screenshots or a random date string get confusing fast once your Gallery fills up with dozens of folders. Renaming an album on your Xiaomi phone does not touch the photos or videos inside it, so nothing gets lost or reordered. This only affects how the folder is labeled in the app, not where the files are stored.
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.
Turn On/Off Dark Mode
If your Xiaomi screen still glares white at night, straining your eyes and eating into battery life, Dark Mode is probably still switched off. MIUI can flip the whole interface to a dark layout, but many users never find the schedule option that would turn it on automatically at a set time. Without that schedule active, you end up switching the toggle by hand every evening.
Mi Browser Privacy and Security Settings
If Mi Browser keeps remembering passwords or search history you would rather not store, the built-in privacy controls are usually still on their default state. Autocomplete, personalized services, and security warnings can each expose more data than expected once you start browsing. Adjusting these toggles one by one gives you control over what Mi Browser saves and shares.
Auto-Fill Empty Home Screen Cells After Uninstalling Apps
When you uninstall an app on a Xiaomi phone, the empty cell it leaves behind can sit unused or the whole layout can shift, depending on one home screen setting. Most people never notice this toggle exists until their icons suddenly rearrange themselves. Knowing where it lives lets you decide whether gaps stay put or close automatically.
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.
Turn Screen Locking Sounds On or Off
Every time your Xiaomi phone locks or unlocks, a short click plays, and it keeps repeating as you use the device throughout the day. That sound comes from the Screen locking sounds option buried in the sound settings, not from notifications or Focus mode. It can be muted or restored in a few taps once you know where it hides.
Name Format for Call History
If some entries in your call log show the first name before the surname while others do the opposite, the phone app is mixing display styles from different contact sources. This happens often after importing contacts from a SIM, another account, or a backup. The call history keeps the format each contact was saved with instead of applying one consistent style.
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.
