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.
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.
Turn Lock Screen Notifications On or Off
Hiding lock screen notifications on your Xiaomi phone keeps message content away from prying eyes, but it also means pop-up alerts stop appearing when the screen is locked. Instead you only see small icons in the status bar, so you have to unlock the phone to check what actually happened. This trade-off between privacy and quick alerts confuses a lot of users switching the setting for the first time.
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.
Show or Hide Password Characters While Typing
On Xiaomi phones, every character you type into a password field flashes briefly on screen before turning into a dot. If you unlock accounts in public, on a video call, or while someone else can see your display, that brief character preview can expose your password to anyone nearby.
Remove a Member from a Contact Group
If a contact still shows up in a group even though you no longer want them there, the fix is not to delete the contact but to unlink them from that specific group. On Xiaomi phones this distinction confuses people because the removal option sits inside the group menu, not in the contact's own profile screen.
Set Always-on Display Duration
If your Always-on display only flashes for a few seconds after you tap the screen, it is set to the short timer instead of staying on permanently. On MIUI you can choose between a brief 10-second preview and a version that stays active the whole time your phone is locked or in standby.
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 Off Developer Options
If Developer options keeps popping up in your Xiaomi settings even though you only enabled it once for a quick fix, it usually just needs to be switched off inside its own menu. Leaving it active keeps USB debugging and other low-level toggles exposed, which can interfere with app checks or banking apps. Turning it off hides the whole menu again until you reactivate it through the hidden tap sequence.
Convert HEIF Photos to JPEG Before Sending
If photos shared from your Xiaomi phone show up as broken files or will not open on someone else's device, the picture was likely saved in HEIF format. Many apps and older phones cannot read HEIF directly, so the recipient sees a blank thumbnail or an error instead of your photo. The Gallery app has a setting that handles this conversion automatically at the moment you send a file.
Turn On/Off USB Debugging
If MyPhoneExplorer refuses to sync contacts or a rooting tool cannot detect your Xiaomi phone over cable, USB debugging is usually still switched off. The option only appears once Developer options are unlocked, and many users cannot find the toggle afterward. Leaving it enabled permanently also carries a small security risk you should know about.
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.
Custom Image on Always-on Display
If the pre-installed Always-on Display themes on your Xiaomi phone all look the same, you can swap them for a photo of your own. MIUI lets you pick any image from your gallery instead of the default clock designs. Once applied, you can still adjust the clock position, text color, and how battery or notification icons appear on top of your picture.
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.
Restart the Xiaomi Smartphone
If apps on your Xiaomi phone start lagging, background downloads get stuck, or the interface feels sluggish after days of uptime, a restart usually clears the problem. MIUI keeps processes and cached data running in the background, and over time this can slow down the whole system. A clean reboot forces MIUI to close every open app and rebuild its memory from scratch.
Stay on Lock Screen After Face Unlock
If your phone jumps straight to the home screen after face unlock, you lose the chance to glance at notifications or widgets on the lock screen first. Other users want the opposite and prefer to land on the home screen right away without an extra tap. This behavior comes from a single toggle hidden inside the Face unlock settings on your Xiaomi phone.
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.
Show or Hide Week Numbers in Calendar
Scheduling an event and trying to figure out which calendar week it falls into turns into quick mental math every time. The Calendar app on Xiaomi phones can display the week number next to every row, but the option sits buried in a settings menu most people never open.
Change Wallpaper on Home Screen
Tapping and holding the home screen only gives you a handful of preset wallpapers to pick from. If you want a specific photo from a particular folder set as your background, that shortcut alone won't get you there.
Adjust Ringtone Volume for Calls and Notifications
If calls ring too loud while notifications stay silent, the culprit is usually the separate volume sliders inside Sound & vibration. Xiaomi phones control ringtone, reminder and notification volume independently, so lowering one slider does not affect the others. This mismatch often causes missed calls or alerts that trigger at the wrong volume.
Uninstall App Updates
If an app starts crashing, draining battery, or losing features right after an update on your Xiaomi phone, the new version is usually the cause. Instead of waiting for another patch, you can roll the app back to the version that shipped with your system and keep your data intact.
Battery Saver: Extra Power Optimization Options
If Battery saver is switched on but your Xiaomi phone still lights up the screen for every notification, the standard saver mode is not doing its full job. Always-on display can also keep draining power even while Battery saver is active. Two extra toggles sit outside the main Battery saver screen and control exactly this behavior.
