Change Keyboard Height
If the on-screen keyboard on your Xiaomi phone feels cramped for typing or covers too much of the screen, the Keyboard height setting is usually the cause. MIUI offers seven size presets from extra short to extra tall, and picking the wrong one makes typos more likely or blocks content you need to see while typing.
Enable or Disable LED Notification Light
If your Xiaomi phone stays dark when a new message arrives, the LED notification light might be switched off for that app. This setting works per app, so one app can flash the LED while another stays silent. Not every Xiaomi model has a physical LED, so the option may be missing entirely on some devices.
Change the Default Browser
Tapping a link on your Xiaomi phone always opens Mi Browser, even though you installed Chrome or another app from the Play Store? This happens because Android keeps using the browser you confirmed as default the first time you opened a link. The new app stays installed but is simply never called until you switch the default setting yourself.
Assign Alarm Functions to Volume Buttons
If your alarm keeps ringing because pressing a volume button does nothing, MIUI lets you change that behavior in the alarm settings. By default the phone treats both volume keys the same way, so you cannot assign a separate action to volume up and volume down. This single setting decides whether a button press snoozes, dismisses or ignores the alarm every single time.
Game Turbo Settings
Game Turbo hides a long list of toggles that most Xiaomi owners never open, covering things like Game Speed Booster, ingame shortcuts and how added apps get removed from the list. If a game still throttles mid-match, notifications keep breaking through, or an external screen behaves oddly while gaming, one of these switches is usually the cause. The settings panel controls all of this from a single screen, but the options are easy to miss.
Turn On/Off Call Recording
If you need proof of what was said on a call, or want to stop your Xiaomi phone from silently recording every conversation, the built-in call recorder is the setting to check. It sits disabled by default, and many users never notice it is there until a recording shows up unexpectedly in the Phone app. Whether you want it running for every call or only for a handful of numbers changes which option you need to pick.
Change Default Messaging App
Texts land in one app while replies keep opening in another, or a new SMS app you downloaded from the Play Store never becomes the one that actually launches. This happens because MIUI keeps a fixed default assignment for messaging that does not update automatically when you install a new app. Until that assignment is changed manually, notifications and quick replies keep routing to the wrong app.
Change App Lock Settings
Once App lock is turned on for an app, MIUI still leaves several details open: notification previews can leak private messages, protected apps might each demand their own unlock, and Xiaomi keeps suggesting more apps to add to the lock. These behaviors come from separate switches inside the App lock settings, not from the lock feature itself.
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.
Set Up Face Unlock
Xiaomi phones store a 2D scan of your face and use the front camera to unlock the screen without a fingerprint or PIN. Before you turn it on, MIUI itself warns that a photo of your face or someone who looks similar could sometimes trigger the same unlock. That trade-off between convenience and security is worth understanding before you register your face.
Switch Contact Name Order (First/Last Name)
If your Xiaomi contact list always shows the first name before the last name, finding people gets harder when you organize contacts by family name or your workplace expects last-name-first lists. This affects how names appear in Contacts, the call log, and message threads alike. MIUI lets you flip that order without editing a single contact.
Start the Screen Recorder
Besides taking screenshots, you can record your Xiaomi screen as a video, but the recorder icon can be tricky to spot among the other Quick Settings tiles. Once recording starts, the small floating control panel fades after about two seconds and shrinks to a barely visible dot, which makes it easy to lose track of how to pause or stop the recording.
Import Contacts from VCF, SIM or Account
If your contacts are stuck on a SIM card, an old VCF backup, or a different account, your Xiaomi phone won't just pick them up automatically. Contacts app import options are easy to miss inside Settings, so people end up re-typing numbers by hand instead of pulling them in from an existing file or account.
Empty the Gallery Trash Bin
Deleted photos and videos in Xiaomi's Gallery app sit in the trash bin for up to 30 days before MIUI deletes them automatically. Until that happens, they still count against your storage, even though you already deleted them. If you want that space back right away, you can clear the trash bin manually instead of waiting.
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.
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.
Quick Settings Panel Access
If toggles like Wi-Fi, Bluetooth, or the flashlight seem to be missing from your quick settings, you probably have not fully expanded the panel yet. On Xiaomi phones, the complete quick settings grid sits behind a second swipe-down gesture, which is easy to miss. Without knowing this, you end up searching the full settings menu for functions that should be a single tap away.
Scan QR Codes Automatically with the Camera App
If your Xiaomi camera does not react to a QR code on a package or shipping label, the Scan QR codes function is likely switched off. Without it, the camera behaves like a normal photo app and shows no scan prompt at all, forcing you to search for a separate scanner app.
Set the Monthly Data Usage Reset Date
If the data usage counter on your Xiaomi phone resets on a different day than your carrier billing cycle starts, the numbers you see never match your actual plan. This happens because the reset date in Data usage is set independently from your SIM contract and has to be adjusted manually. Without matching it, data warnings and remaining allowance calculations stay inaccurate all month.
Forget Saved Wi-Fi Networks
If your phone keeps reconnecting to a slow or wrong Wi-Fi network instead of your home connection, an outdated saved entry is usually the cause. This often happens after a router password change or when two networks share the same name. Removing the old entry forces your Xiaomi phone to ask for the current password the next time it connects.
Turn Screenshot Sound On or Off
Every time you capture a screenshot on a Xiaomi phone, a short chime plays to confirm the capture went through. If that sound feels too loud in meetings or you simply want an audible confirmation back, the setting sits separately from your general ringtone volume and needs its own toggle.
How to Turn on/off Airplane mode
If your Xiaomi phone suddenly stops receiving calls, texts, or mobile data, Airplane mode is often the reason. Turning it on shuts down the mobile network, mobile data, WLAN, and Bluetooth at the same time. On some Xiaomi phones you can still switch WLAN or Bluetooth back on manually while Airplane mode stays active, which causes confusion when connectivity only half works.
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.
Set Start of Week in Calendar
If your calendar always opens on a Sunday even though you expect Monday to be the first column, the app is just following the region setting on your phone. This mismatch makes weekly planning confusing, especially when you compare dates with colleagues or family using a different week layout. A quick setting inside the Calendar app fixes the view for good.
