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.
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 On/Off Mono Audio
If music, videos or calls sound identical from both speakers on your Xiaomi phone, Mono audio is switched on. This accessibility feature merges the left and right channels so every clip and call plays the same content on each side. It's meant for hearing support, not everyday stereo listening.
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.
Merge Duplicate Contacts
When contacts get saved by different apps or sync sources, the same person can end up listed twice in your Xiaomi contact list. This duplication clutters your call log, messages, and search results, making it harder to reach the right entry fast. MIUI includes a built-in way to link matching entries back into a single, clean contact.
Turn On/Off Switch to Speaker Automatically
If your Xiaomi phone keeps the call on the earpiece even after you pull it away from your face, or the speaker never kicks in on its own, a hidden accessibility feature is likely involved. This function relies on TalkBack and sits inside a section labeled Experimental, which is why most people never find it. Without it enabled correctly, calls stay locked to the earpiece no matter how you hold the phone.
Remove a Keyboard Language
Too many keyboard languages clutter the language switcher and slow down cycling to the one you actually type in. On Xiaomi phones, unused layouts stay listed under keyboard management until you remove them manually, even if you only tried them once.
Turn Google Location History On or Off
If Google Maps keeps suggesting places based on where you have been, or your Timeline fills up with stops you never meant to save, Location History is still active in the background. On Xiaomi phones this tracking can run even when no Google app is currently open, which surprises a lot of users checking their data usage or battery drain.
Set Monthly Data Usage Limit
If your Xiaomi phone still enforces the data limit from an old tariff, warnings or automatic data cut-offs can trigger at the wrong point in your billing cycle. The Monthly data limit value under Data usage does not update itself when your plan changes or your provider raises your allowance. You have to adjust it manually to match the new tariff.
Turn USB Tethering On or Off
When you plug your Xiaomi phone into a PC or laptop to share its mobile data, the computer often prompts you to pick a connection type instead of connecting automatically. This happens because USB tethering sits in a separate toggle from your regular USB file-transfer mode. Without switching it on first, the cable only charges the phone or transfers files instead of sharing the data connection.
Switch Between Browser Tabs
Comparing prices or articles across several websites gets confusing fast if you cannot jump between open pages in Mi Browser. On Xiaomi phones the tab overview is easy to miss, so people end up closing and reopening pages instead of switching between them directly.
Block a Number from Call History
Spam calls from fake lottery winnings or gambling subscriptions keep showing up in your call log even after you hang up. On Xiaomi phones, blocking a caller straight from that log is often faster than adding them manually through Contacts. Here's what triggers the block option and where it actually lives in the Phone app.
Factory Reset via Settings
When your Xiaomi phone gets stuck in a lag loop, refuses to accept a new owner, or you just want to wipe it before selling it, a full factory reset is often the only clean fix. The Erase all data function removes every account, app, and system setting from internal storage without a way to undo it. Before you start, it helps to know exactly what gets deleted and what stays untouched.
Add a Contact Shortcut to the Home Screen
Calling the same person every day shouldn't require opening the Phone app, searching your contacts and tapping through to their number each time. On MIUI you can pin a direct contact shortcut to your home screen so a call or message starts in just two taps. This helps most with family, coworkers or anyone else you dial constantly.
Add a Printer via IP Address or Wi-Fi Direct
If your printer does not show up automatically even though your phone and printer share the same Wi-Fi network, MIUI still lets you add it manually. This usually happens with older printers, devices on a different subnet, or printers that only support Wi-Fi Direct instead of standard network discovery. In that case you need to enter the printer's IP address yourself or switch on Wi-Fi Direct printing directly from the printing menu.
Auto-Update Download Settings
If your Xiaomi phone keeps downloading system updates in the background without asking, it can eat into your data plan or fill up storage at the worst moment. On the other hand, if updates never download automatically, you might miss important security patches for weeks. This behavior is controlled by a single toggle buried inside the MIUI version screen, separate from the mobile data download option next to it.
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.
Set the WiFi Hotspot Band
If your Xiaomi hotspot always connects on the slower 2.4GHz band, other devices lose out on faster 5GHz speeds. Not every phone or app picks the best signal automatically, so a laptop or smart TV might latch onto the weaker frequency even when 5GHz is available. Whether you can switch depends on the AP Band option being supported by your device.
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.
Delete Learned Words and Data
If the built-in Xiaomi keyboard keeps suggesting outdated or wrong words, the learned word database is usually the cause. This data builds up over time from everything you type and can make autocorrect feel stuck on old habits. Clearing it resets suggestions without touching your other settings.
Set the Action for When Your Data Plan Runs Out
If your mobile data suddenly stops working before the month is over, MIUI may already be cutting it off automatically once you hit your set limit. Some people only want a heads-up instead of losing their connection outright, but that only works if the right action is selected in the data usage settings. Without checking this setting, you can end up with dead mobile data at the worst possible moment.
