Notifications & Focus2

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.

Photo, Video & Media2

Create an Album in Gallery

When photos and videos pile up in one long timeline, finding a specific trip or event gets tedious fast. The Gallery app on Xiaomi phones sorts everything by date by default, with no automatic grouping by topic or person. Creating a custom album lets you pull selected photos and videos into one place without digging through months of camera roll.

Calls & Messages2

Copy a Text Message

Need to reuse a phone number, code, or address from an SMS without retyping it? On Xiaomi phones the copy option for a text message only appears after a precise long press, and it is easy to miss if you tap the wrong spot on the bubble. Here is where the Copy command actually shows up inside the Messages app.

Network & Connectivity2

Select Network Manually

When you travel abroad and your phone keeps hanging on a weak carrier, automatic network selection is usually the cause. MIUI picks a network by signal priority, not by actual reception quality, so calls drop and data stalls even though a stronger carrier is available nearby. Switching to manual selection lets you pick that carrier yourself instead of waiting for the phone to reconnect.

Open
Notifications & Focus2

Allow Repeated Calls in Do Not Disturb

When Do Not Disturb is active on your Xiaomi phone, every incoming call gets silenced, even urgent ones. MIUI has a separate setting that lets a second call from the same number within a short window ring through instead of staying muted.

Apps & Installation2

Turn Off Suggestions in Recent Apps Menu

If your recent apps screen on a Xiaomi phone keeps showing extra tiles for Cleaner, Security scan, Deep cleaning or Manage Apps, a system suggestion feature is adding them automatically. This can make the app switcher feel cluttered and slower to scan through, especially if you only want to see your open apps.

Switch Between Old and New Control Center Style

If your Xiaomi phone still shows the older two-panel layout after an update, or you miss that classic view after switching to the newer simplified overview, the display style does not change on its own. It sits behind a separate setting that many people never open. Notifications and quick toggles stay mixed together until you pick the layout you actually want.

Photo, Video & Media2

Delete an Album in Gallery

Deleting an album on your Xiaomi phone also deletes every photo and video still stored inside it. This catches a lot of people off guard when they just wanted to tidy up their Gallery app and end up losing media they meant to keep. Knowing which albums are safe to remove and which ones hold originals is key before you tap delete.

Fix Fisheye Distortion in Ultra Wide Shots

Ultra wide shots on your Xiaomi phone sometimes bulge at the edges, making straight lines look curved like a fisheye lens. This happens because the wide field of view stretches objects near the corners of the frame. The camera app can correct this automatically, but the setting is easy to overlook.

Open
System & Settings2

Switch to Scientific Calculator Mode

You open the Calculator app on your Xiaomi phone expecting only basic math, but functions like sine, cosine, tangent, square roots or Pi are nowhere to be found. Many users assume the app simply lacks these tools, when in fact they are hidden behind a display mode that most people never trigger. Without knowing the trick, you end up switching to a third-party app for calculations your phone already supports.

System & Settings2

Add New Browser Tabs

Closing your current page every time you want to check something else in Mi Browser gets old fast. If you cannot find a way to browse two pages at once without losing your place, the tab feature in Mi Browser solves that without extra apps.

Open
Network & Connectivity2

Turn Wi-Fi Auto Reconnect On or Off

If your Xiaomi phone keeps rejoining a Wi-Fi network you would rather avoid, or the connection drops every time you walk back into range, the Connect automatically option tied to that specific network is behind it. MIUI turns this behavior on by default for every network you have ever joined, and it stays active until you switch it off for that network individually. That is also why disabling it on one network never changes the behavior of the others.

Open
Apps & Installation2

Manage Updates for System Apps

If your Xiaomi phone keeps nagging you about system app updates - or stays silent when new versions are actually ready - the System apps updater settings are probably not set the way you want. MIUI lets you control whether update notifications show up, whether updates install automatically, and whether downloads run on Wi-Fi only or also over mobile data. Leaving these settings on default can mean unexpected data usage or missed fixes.

Calls & Messages

Set an Alternate Calendar

If your Calendar app only shows the Gregorian calendar, dates for other systems like the Hijri, Hebrew or Chinese calendar stay invisible in event details. This is controlled by a setting hidden inside General settings that most people never open.

Accessibility2

Change Font Size

Reading long texts on a small screen strains your eyes if the system font stays too small, and cranking up brightness alone does not fix that. On Xiaomi phones the text scale sits in its own menu, separate from general display settings, which is why many people never find it. MIUI offers six size steps instead of a simple small/medium/large switch, so getting the right level takes a bit of trial and error.

Open
Notifications & Focus2

Schedule Do Not Disturb Automatically

If Do Not Disturb only works when you remember to switch it on, notifications still slip through during meetings or overnight. MIUI can run silent or Do Not Disturb mode on its own recurring schedule, but the settings for start time, repetition and mode type are easy to miss.

Open
Apps & Installation2

Set a Timer in the Clock App

Setting an alarm just to catch the end of an eBay auction wastes a reminder slot and still leaves you guessing when to check back. The Timer function in the Clock app on your Xiaomi phone counts down a fixed period and alerts you the moment it is over, without touching your alarm list. Many users overlook this tool because it sits next to the alarm and stopwatch tabs and rarely gets used.

Open
Calls & Messages

Change Contacts App Theme (Light or Dark)

On Xiaomi phones, the Contacts app can keep its own light or dark look even after you switch the phone-wide display mode in system settings. That mismatch happens because the app ships with a separate theme option that overrides the system default. Calls and messages screens can stay bright at night or dark during the day because of it.

Open
Battery & Power

Auto-Disable Ultra Battery Saver at 50% Charge

Once your Xiaomi phone reaches around 50% charge, Ultra battery saver can switch itself off without asking, dropping all the restrictions it just applied. If you rely on the extreme power-saving mode staying active until you manually turn it off, this automatic behavior gets in the way. The setting controlling this is separate from the regular battery saver toggle.

Turn Personalized Ad Recommendations On or Off

If ads on your Xiaomi phone feel oddly tied to your recent searches or app activity, Personalized ad recommendations is the setting behind it. Switching it off does not lower how many banners you see, it only stops MIUI from matching them to your interests and usage data.

Open
Network & Connectivity2

Turn Portable Wi-Fi Hotspot On or Off

If other devices cannot get online through your Xiaomi phone, the portable hotspot might simply be switched off or still using a network name and password you do not remember. This feature turns your mobile data connection into a Wi-Fi network for laptops, tablets or other phones nearby. Once it is active, the tricky part is usually finding the right toggle again, since it sits inside a settings screen most people only visit once.

Open
Security & Privacy

Manage Device Administrator Apps

An app you want to uninstall on your Xiaomi phone refuses to go away, or a widget keeps nagging you about admin permissions. Device administrator apps get elevated rights to change security settings or wipe data remotely, which is exactly what blocks a normal uninstall. Turning off that permission is usually the fix before the app can finally be removed.

Open
Accessibility2

Turn On High Contrast Text

Thin system fonts in MIUI can blur together against busy wallpapers or in bright sunlight, which makes reading notifications and menus tiring. The High contrast text option adds a bold black outline around letters to separate them from the background. On several Xiaomi phones this switch sits in an experimental accessibility section, so it can behave slightly differently between apps.

Photo, Video & Media

Turn Auto-sync for Photos and Videos On or Off

If your Gallery keeps pushing photos and videos to Xiaomi Cloud even on mobile data, your storage plan fills up fast and your data allowance takes a hit. The sync behavior is controlled from within the Gallery app and tied to the Mi account signed in on the phone. Turning it off stops new uploads, but files already sent to the cloud stay there until you remove them yourself.
