Show or Hide Declined Calendar Events
Declined meeting invites disappear from the Xiaomi Calendar app by default, so you cannot see which appointments you turned down or check past responses. This happens because the toggle that controls declined-event visibility is switched off in the calendar settings. Depending on how your Google account syncs, hidden entries can also make your event history look incomplete.
Set Up Unlock with Bluetooth Device
If your Xiaomi phone stays locked even though your paired Bluetooth accessory is nearby, the Unlock with Bluetooth device feature is probably still off. Once active, the phone unlocks automatically near that device and stays unlocked as long as the connection holds. This only works with Xiaomi's own Bluetooth accessories, not with third-party headphones or wearables.
Camera Delay-Timer
If your Xiaomi camera fires the shutter the instant you tap the button, group photos or selfies often turn out blurry or catch you mid-pose. MIUI has a built-in delay-timer for exactly this situation, but it sits hidden inside the camera menu instead of the main shooting screen. Without it, you only get a split second to get into position before the shot is taken.
Unarchive a Conversation
Archived chats disappear from the main Messages overview on Xiaomi phones, which makes them easy to lose track of. If you archived a conversation by mistake or need to reply again, it stays hidden until you move it back manually. The message thread stays fully intact in the Archived folder, ready to be restored at any time.
Delete a Folder from the Home Screen
A folder that still holds one or two apps refuses to disappear no matter how often you tap on it. MIUI does not offer a direct delete button inside the folder itself, which confuses a lot of users. The trick lies in how you grab and move the folder icon, not in emptying it app by app.
Uninstall an App
Old apps you never open still take up storage on a Xiaomi phone, and the app drawer gets crowded fast. Dragging an icon off the home screen sometimes only removes a shortcut instead of the actual app, which is confusing if the storage warning keeps coming back. Uninstalling deletes the app together with all its saved data permanently, so it helps to know exactly which tap does what before you remove several apps at once.
Delete an APN Entry
A wrong or duplicate access point can block mobile data or MMS on your Xiaomi phone, even after you switch carriers or SIM cards. If an old APN profile stays behind, the device sometimes keeps trying to use it instead of the correct one. Removing the unused entry clears up the confusion without touching your other network settings.
Camera Watermarks
The camera watermark stamps a small label into the lower-left corner of your photos, either a standard device signature or a text you choose yourself. It helps you mark ownership, keep track of the device a shot came from, or add a personal touch for photos you share or sell online. Turning it on or off changes future shots only, not photos already stored in your gallery.
Set a Default Calling SIM for a Contact
On a dual-SIM Xiaomi phone, calling a specific person always triggers the SIM prompt, even though you always pick the same card for that number. This happens because the contact has no fixed calling SIM assigned, so MIUI asks every time before dialing out.
Manage Notifications for Individual Apps
If one chatty app keeps popping up over whatever you're doing, or a messaging app reveals message previews on the lock screen when you'd rather it didn't, the fix isn't a single master switch. On Xiaomi phones, every app has its own notification behavior for sound, pop-ups, banners, and lock screen visibility. Without adjusting the right app individually, the annoying alerts keep coming back.
Restore Deleted Contacts from Trash Bin
Accidentally deleted a contact on your Xiaomi phone and now you cannot call or message that person? MIUI keeps removed contacts in a separate Trash folder before they disappear for good, so nothing is lost right away. You just need to find that folder before the 30-day window runs out.
Change Calendar View
If your Google Calendar app on Xiaomi always opens in Month view, finding today's appointments takes extra scrolling. The default layout does not match how you actually plan your day. Switching between Schedule, Day, 3-Day, Week and Month views fixes this without touching any system settings.
Turn Read in Background On or Off for Select to Speak
When Select to Speak keeps talking after you leave an app, the Read in background option is doing its job, but not everyone wants that. Xiaomi flags this feature as experimental, so it can behave inconsistently between MIUI versions and sometimes keeps narrating text you no longer need read aloud. Knowing where the toggle sits helps you decide whether the trade-off is worth it.
Turn On Automatic Backup for Storage and Data
If you only remember to back up your Xiaomi phone after something breaks or gets lost, relying on manual backups is the real problem. MIUI can schedule backups on its own, but the default days, time, and data selection may not match how you actually use your phone. Getting the schedule wrong means backups either pile up unnecessarily or miss the files you actually care about.
Quick Settings Panel Guide
Missing toggles in the Quick Settings panel force you to dig through the full settings app for basic switches like Flashlight, Hotspot or Battery saver. On Xiaomi phones, MIUI splits the panel across two swipe-down layers, so some tiles stay hidden until you swipe down again. Reordering or removing tiles you rarely use is simple once you find the edit mode.
Schedule Battery Saver Automatically
Turning Battery saver on and off by hand every night gets old fast, and it's easy to forget before you go to sleep. If you leave it running into the morning, background apps and notifications stay throttled longer than you need. MIUI lets you set fixed start and end times so the mode switches itself.
Enable Developer Options
On Xiaomi phones the Developer options menu stays hidden by default, so options like USB debugging or animation speed are nowhere to be found in Settings. MIUI locks this menu on purpose because most entries are meant for app testing, not daily use. A short tap sequence on one system value unlocks the hidden menu.
Set a Custom Timer Ringtone
If the timer on your Xiaomi phone keeps playing the same generic tone, you probably want something you actually notice - or one you can tune down for lighter naps. MIUI lets you swap the timer sound for a pre-installed ringtone or your own .mp3 file, but the option sits several taps deep inside the Clock app and is easy to miss. Picking the wrong file type can also mean silence instead of a sound.
Turn On/Off Dial Pad Tones
Every digit you tap on the Xiaomi phone app's dial pad triggers a short beep, and that tone lives in a settings menu that has nothing to do with the calling app itself. In quiet places or shared rooms, that repeated clicking sound gets annoying fast, especially if you dial full numbers manually. Other users want the opposite problem solved: the tone stopped playing and they miss the tactile feedback while typing a number.
Change Alarm Volume
If the alarm on your Xiaomi phone barely wakes you up or does not go off loud enough, the alarm volume is set too low system-wide. This one setting controls every alarm you create, and it stays the same even after the snooze function kicks in.
Clear Mi Browser Cache and History
If Mi Browser keeps loading outdated versions of pages or autofill suggests search terms you deleted weeks ago, leftover cache and history data is usually the reason. Stored cookies and site data from various websites pile up over time and can also cause login loops or slow page loading on Xiaomi phones. You can clear everything at once or pick individual categories like cache, history, or cookies.
Adjust TalkBack Advanced Settings
Once TalkBack is active on a Xiaomi phone, the whole touchscreen behaves differently and simple taps stop opening apps directly. Many users get stuck because the default gestures feel slow or accidentally trigger the wrong action. Xiaomi phones offer several TalkBack options like Single-tap activation, touch gestures, keyboard shortcuts and custom labels to fix this.
Connect Manually to a Hidden Wi-Fi Network
If your Xiaomi phone does not list a wireless network under available connections, the router is likely broadcasting with a hidden SSID or sitting outside the usual scan range. In that case MIUI needs the exact network name and password entered by hand instead of picking the network from a list. Typing the SSID wrong or missing the correct security type is the most common reason the manual entry still fails.
Share a Webpage from Mi Browser
Copying a website address by hand often cuts off part of the link or drops tracking parameters that break the page. Mi Browser can send the page straight to WhatsApp, Gmail or Messages, but the share option sits inside the profile menu instead of the main toolbar. Many people end up scrolling through icons before finding the right one.
