Format an SD Card
A newly inserted SD card sometimes won't work correctly in a Xiaomi phone, or you want to wipe an old card before reusing it. Formatting clears the card and lets MIUI set up the folder structure it needs to store photos, videos and app data properly. Once you confirm the format, every file on the card is gone for good.
Change Device Name
If your Xiaomi phone still shows up under its model number when you scan for Bluetooth devices or connect to a hotspot, that is the default device name at work. It makes picking your phone out of a list of nearby devices harder, especially if you own more than one Xiaomi device. MIUI lets you replace that generic label with a name you actually recognize.
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.
Enlarge the Mouse Pointer
When you plug a USB mouse or similar pointing accessory into a Xiaomi phone, the on-screen pointer often stays tiny and hard to track. Large mouse pointer is a dedicated Accessibility option built for exactly this situation, especially useful for anyone with limited vision. Without enabling it, you end up guessing where the cursor sits on a crowded screen.
Pocket Mode in the Camera App
If your phone's camera keeps opening or snapping photos while it's still in your pocket, stray touches on the screen are usually the cause. Pocket mode locks the touchscreen once the sensor detects the phone is stored away, blocking accidental swipes and taps. When the camera reacts to pocket movement or the screen stays unresponsive after you pull the phone out, this setting is worth checking.
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.
Show or Hide the Emoji Switch Key
If you type a lot of emojis, switching between the language globe and the emoji picker can slow you down on the MIUI keyboard. The globe icon and the emoji key share the same spot, so only one of them shows on the keyboard row at a time. Turning on the emoji switch key swaps that icon while quick language switching still works by holding the space bar.
Change Webpage Text Size in Mi Browser
If text on websites looks too small to read comfortably or too large and forces constant scrolling in Mi Browser, the webpage display size is set to the wrong level. Xiaomi phones offer five separate font sizes for browsing, independent from the system font size in your general settings. Switching to a different level fixes cramped or oversized text on every site you visit.
Enterprise Mode
If you spot Enterprise mode buried in your Xiaomi settings and have no idea what switched it on, you are not alone. The feature is built for companies that want to restrict which apps or websites an employee device can reach, and in some setups it can also report device activity back to an administrator. On a private phone that was never enrolled by a company, this toggle usually just sits there unused, which raises the question of what it is doing and whether it is safe to leave alone.
Change Alarm Tone
If your Xiaomi alarm keeps ringing with the same generic tone or the Nature alarm sound never changes, the ringtone categories in the Clock app are likely the reason. Some categories, like Nature alarm, only rotate through different sounds when the phone has an active internet connection. Without that connection, the alarm falls back to a stored default tone instead of downloading a new one.
Allow Gallery Access to SD Card
If Gallery on your Xiaomi phone refuses to save new photos or won't let you delete files on the SD card, it usually means storage access was never granted. Android blocks apps from writing to external storage until you confirm the permission for that specific card. Until you approve it, Gallery can only display existing files but not create, move or remove anything on the card.
Turn Emergency Alerts On or Off
If your Xiaomi phone keeps buzzing with Amber Alerts or severe weather warnings you never signed up for, the Emergency alerts feature is likely still active in the background. Some people want the opposite and need extreme threat notifications, vibration and voice alerts to actually get through. Either way, the switch sits in a security menu that is easy to overlook.
Set Snooze Time and Repetition
If your Xiaomi alarm keeps snoozing for too long or not often enough, the default snooze interval and repeat count are likely not adjusted to your needs. MIUI lets you fine-tune both values, but the option sits several menus deep in the alarm settings.
Remove Google Search Bar from Home Screen
After the first setup of a new Xiaomi phone, a Google Search bar sits on the home screen by default and takes up space you might want for widgets or app icons. Many people assume it is a fixed part of MIUI and leave it there without checking. It is actually just a removable widget, so getting rid of it does not require digging through any settings menu.
Turn Location Access On or Off
If maps, weather, or camera apps suddenly stop finding your position on a Xiaomi phone, the general location toggle in MIUI settings might be switched off. Turning it off blocks GPS for every app at once, even those you already granted permission to use your location. This differs from per-app location permissions, which stay untouched but simply can't function without the master switch.
Turn Automatic Date & Time On or Off
If your Xiaomi phone shows the wrong time after a trip or SIM swap, the automatic time sync is likely still active. Automatic date & time relies on network-provided time, which can lag or fail when signal is weak. Turning it off lets you set the clock manually instead.
Missed Call Reminders: Turn On or Off
If a missed call slips by unnoticed until hours later, missed call reminders are probably switched off or set to repeat only once. MIUI can nudge you again about an unanswered call, and the number of repeats is adjustable. Without this setting active, a single missed call notification is easy to swipe away and forget.
Assign Custom Button Shortcuts
If double-pressing the power button always opens the camera when you wanted a screenshot instead, the button shortcut linked to that gesture doesn't match how you actually use your phone. MIUI lets you remap gestures like double-press power or long-press volume to actions such as torch, split screen or Google Assistant. Finding and changing that mapping means digging through a settings menu that isn't obvious at first glance.
Turn On/Off Read Text on Images (Select to Speak)
When Select to Speak on your Xiaomi phone starts reading text from photos or the camera viewfinder out loud, the Read text on images option is active. Xiaomi flags this as an experimental function, so it can misread words, skip lines entirely, or lag behind what the camera actually shows. Knowing where to switch it off helps once the readouts cause more confusion than they solve.
Set a New Alarm
Waking up on time with a Xiaomi phone means finding the right spot to add a repeating schedule, a custom label, or a different ringtone for each alarm. Many users only set a one-off alarm and miss the options for weekday repetition, vibration, or automatic deletion after the alarm rings. Getting these details wrong means the alarm either fires on the wrong days or disappears after a single use when you actually wanted it daily.
Change Camera Picture Quality
If your camera storage fills up fast or photos take too long to share, the picture quality setting in the MIUI camera app is often the reason. Xiaomi's camera defaults to a high resolution that produces large files, even when you only need a quick snapshot. Switching between High, Standard, and Low lets you balance sharpness against file size for each situation.
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.
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.
