Set a Custom Watermark in the Camera App

If every photo automatically shows your device or camera model as a watermark, you might want your own text there instead. The Watermark settings inside the Camera app let you swap that default label for a personal signature, but the option sits a few taps deep in the menu. Once set, the custom text gets stamped on every new shot instead of the model name.

Notifications & Focus2

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.

Turn On/Off Device Watermark on Photos

Every photo you take with your Xiaomi phone gets a small watermark in the bottom left corner, showing which device captured the shot. If you want cleaner images for sharing or printing, that watermark can get in the way fast.

Security & Privacy2

Remove a Stored Fingerprint

If a fingerprint still unlocks your Xiaomi phone after you sold it, handed it to someone else, or just registered a bad scan, that print needs to go. MIUI stores several fingerprints under one name, so it is easy to remove the wrong one by mistake. Deleting a print always asks for your unlock pattern, PIN or password first, which trips up people who only remember using their finger.

System & Settings2

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.

Open
Security & Privacy2

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.

Network & Connectivity2

Limit Connected Hotspot Devices

By default, your Xiaomi phone lets an unlimited number of devices join your mobile hotspot at once. That can slow down your connection and makes it hard to track who is actually using your data. Setting a maximum device count gives you back control over who connects.

Open
Apps & Installation2

Show Memory Status in Recent Apps

When you swipe up to check recent apps on a Xiaomi phone, the memory bar at the top sometimes just isn't there, leaving you without a quick read on free RAM. This indicator only reports live usage and does not close or manage background apps on its own. Without it turned on, you lose a fast way to judge whether your phone is actually running low on memory.

Network & Connectivity2

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.

View Device Certification Info

If you need your Xiaomi phone's FCC ID, model number, or other certification details for a return, insurance claim, or customs check, they are not printed on the box or shown in a quick settings toggle. This information sits inside a dedicated certification screen that most users never open on their own.

Open
Display & Home Screen2

Turn On/Off Auto Brightness

If your Xiaomi screen keeps getting brighter or dimmer without you touching anything, Auto Brightness is reacting to the light sensor. You can still drag the brightness slider manually while the function stays active, which often causes confusion about which setting is actually in control.

Open
System & Settings2

Check for System Updates

If you swiped away the update notification on your Xiaomi phone or never saw it pop up, the update itself is not lost. MIUI still tracks it in the background, you just need to trigger the check yourself. This matters when a security patch or bugfix has been sitting unnoticed for weeks.

Open
System & Settings2

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.

Photo, Video & Media

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.

Open
Storage & Backup2

Back Up Your Phone to Xiaomi Cloud

If your Xiaomi phone breaks or gets lost, photos, contacts and app data are gone unless a cloud backup exists. Many users assume MIUI backs up automatically, but Xiaomi Cloud sync stays off until you sign in with a Mi account and switch it on. Without that step, only local backups on the device itself exist, and those disappear along with the phone.

Open
System & Settings2

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.

Open
System & Settings2

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.

Open
Photo, Video & Media

Silence Media Automatically in Silent Mode

When you switch your Xiaomi phone to Silent mode, videos, games and other media keep playing sound anyway. That happens because 'Silence media in Silent mode' is a separate toggle in the sound settings, not something Silent mode covers on its own.

Open
Calls & Messages2

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.

Open
System & Settings2

Turn On/Off Pop-up on Keypress

If every letter you tap on your Xiaomi keyboard flashes up in a small preview bubble, typing can feel slower and the screen looks cluttered. This preview comes from a keyboard setting called Popup on keypress, and it can get in the way when you type quickly in Messenger, WhatsApp or any other app. You can switch it on or off directly in the keyboard settings on your phone.

Open
Notifications & Focus2

Turn Tap Sounds On or Off

Every tap on a button, the Back key, or a menu item triggers a short click sound on your Xiaomi phone. If that noise gets distracting during calls, meetings, or at night, the Tap sounds setting is behind it and can be switched off just as quickly as it can be turned back on.

Open
Battery & Power2

Turn Off Battery Saver Automatically After Charging

If Battery saver stays active even after your Xiaomi phone finishes charging, it keeps throttling performance and dimming the screen longer than needed. MIUI can switch Battery saver off on its own once the battery reaches a set charge level, so you don't have to remember to disable it by hand every time you unplug the charger.

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.
