Show or Hide Carrier Name on Lock Screen
If your Xiaomi lock screen shows the SIM carrier name under the clock, a MIUI status bar setting is behind it. Some people want that text gone for a cleaner lock screen or extra privacy, while others lose it after a reset and want it back. Either way, the toggle sits in one specific settings screen and is easy to miss.
Turn Auto-correction On or Off
If your Xiaomi keyboard keeps swapping in a word you never typed, MIUI auto-correction is stepping in before you finish a sentence. It usually helps, but on names, slang or foreign words it can turn a normal message into something embarrassing. The feature sits in the keyboard settings and you can switch it on or off depending on how you type.
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If your phone keeps reconnecting to a slow or wrong Wi-Fi network instead of your home connection, an outdated saved entry is usually the cause.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 Vibration on Tap On or Off
Every tap on your Xiaomi screen can trigger a short buzz, and if that feels too strong or barely noticeable, the haptic feedback setting is usually the cause. MIUI lets you switch this tap vibration off completely or pick between three intensity levels. The same control also affects the buzz you feel while typing on the keyboard.
Route a Contact Straight to Voicemail
When a specific contact keeps calling at bad times, you do not have to reject the call manually every time. MIUI lets you route calls from a single contact straight to voicemail while everyone else still gets through as normal.
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.
Mount SD Card
If you tapped Eject SD card or safely removed the card from your Xiaomi phone, the storage disappears from your file manager and apps stop saving to it. MIUI keeps the card unmounted until you tell it to reconnect, even after a reboot in some cases. Photos, downloads, and app data meant for the card get redirected to internal storage instead.
Filter Call History
When your Xiaomi call log fills up with dozens of entries, finding a specific missed or outgoing call turns into scrolling work. The Phone app on MIUI stores every call in one long list without separating calls by type or SIM card by default. A built-in filter option sorts the log so you only see the calls that matter.
Turn Auto-capitalization On or Off
If your Xiaomi keyboard keeps capitalizing letters you want lowercase - like usernames, code snippets, or crypto addresses - auto-capitalization is likely running in the background. It automatically capitalizes the first letter after a period or new sentence, which speeds up regular typing but gets in the way for technical text. The setting sits inside the keyboard's text correction options, not the main system settings.
Set Up Automatic Cache Clearing
Cache files pile up quietly in the background and can eat into your storage or slow down apps over time. Xiaomi phones running MIUI include a setting that clears this cache on its own once the screen locks, but it is off or set to a schedule you may not want. Adjusting the timing decides how often your device cleans up automatically without you doing it by hand.
Turn On/Off Call Forwarding
Calls landing in voicemail even though your phone never rang usually means call forwarding is already active in the background. On many Xiaomi phones the network sets forwarding for 'busy', 'unanswered' and 'unreachable' cases by default, so you might not notice it until a call disappears. Each of these forwarding rules can be switched on or off separately, or redirected to a different number entirely.
Set the Default Media Volume Level
Videos, music, and games on your Xiaomi phone start way too loud or too quiet, and pressing the Volume buttons only helps once something is already playing. That happens because Media volume runs on its own channel, separate from ringtone and notification levels in MIUI.
Turn Color Inversion On or Off
If your Xiaomi phone suddenly shows a black background with white text everywhere, or photos and videos look like a photo negative, Color inversion is likely switched on. This accessibility feature swaps colors system-wide, including in apps, galleries, and the camera preview, which can make the phone look broken until you know where to turn it off.
Schedule Reading Mode Automatically
Reading mode does not switch itself on unless you tell it when to run, so the display keeps its normal cool color balance even in the evening. Turning it on manually every night is easy to forget, which defeats the purpose of reducing blue light before bed. A schedule lets Reading mode start and stop on its own, either at fixed times or automatically around sunset.
Turn On/Off App Drawer
If every installed app sits directly on your Xiaomi home screens instead of in a separate overview, MIUI's app drawer setting is turned off. Switching between 'Classic' and 'With App drawer' changes whether a swipe on an empty area opens a full app list or just adds more home screen pages.
Turn On/Off Contact Suggestions
When Contact suggestions are active on a Xiaomi phone, the keyboard pulls names, numbers and email addresses from your Contacts app while you type messages or fill out forms. That can be handy for quick replies, but it also means personal details from your address book show up as autocomplete hints in apps that have nothing to do with Contacts. If you want tighter control over what your keyboard suggests, this setting is the one to check.
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.
Turn Accessibility Menu Shortcut On or Off
If a small floating icon suddenly shows up in the bottom right corner of your screen on your Xiaomi phone, the Accessibility menu shortcut has been switched on. This icon opens a panel with accessibility actions and does not change how the rest of the phone works. You can turn it on or off depending on whether you actually need those accessibility tools.
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.
Hide and Show Apps on the Home Screen
If an app keeps showing up on your home screen even though you do not want it visible, MIUI can hide it completely as long as App lock is turned on. Without App lock active, the option to hide apps simply does not appear in the menu. Once hidden, an app only reappears after you unlock it with your password or pattern.
Reset Mi Browser Settings
If Mi Browser keeps loading a search engine you never picked, autofill won't clear, or saved passwords and history pile up without an obvious way to clean them individually, restoring the browser to its defaults fixes all of that in one step. This wipes personal settings and locally stored browsing data together, so it helps most when smaller fixes like clearing cache alone did not solve the problem.
App Lock Timing
If App lock keeps asking for your PIN every time you switch briefly between apps, the delay is probably set too tight. Xiaomi lets you choose whether protected apps lock the instant the screen turns off, right after you leave the app, or after a short grace period. Picking the wrong option means either constant re-entry or apps staying unlocked longer than you want.
Turn Off Mobile Data When Device Is Locked
If your Xiaomi phone keeps burning through mobile data even while sitting locked in your pocket, a background data setting is likely still active. MIUI can cut mobile data automatically once the screen locks, but the delay before that happens is often left on a setting that does not match how you use the phone. That gap is what causes messages, emails or app updates to keep syncing long after you stopped looking at the screen.
Assign a Custom Ringtone to a Contact
If every incoming call sounds the same, you have to check the screen to know who is calling before you pick up. On Xiaomi phones, the default ringtone applies to all contacts unless you override it manually for specific people.
