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.
Turn a Keyboard On or Off
A new keyboard downloaded from the Play Store does not automatically show up next to Gboard on your Xiaomi phone. Until you switch it on in the input settings, it stays hidden from the language switcher and typing keeps defaulting to the old keyboard. This usually happens with third-party layouts, handwriting keyboards, or apps installed after the initial setup.
Disable Swipe-Up Search on Home Screen
On Xiaomi phones, swiping up from the home screen opens search by default instead of doing anything else. That gets in the way if you accidentally trigger it while scrolling widgets or switching between screens. The option to turn it off only shows up when the app drawer is disabled.
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.
Restrict Mobile Data Usage for an App
If a Xiaomi phone burns through your data plan even though you barely open certain apps, background data access is usually the cause. By default every installed app can use mobile data and Wi-Fi without restriction. On dual-SIM phones this applies separately to each SIM slot, which makes it harder to spot which line is actually consuming the data.
Edit and Rearrange Quick Settings
If the toggle you need most sits at the bottom of the control center or is missing entirely, you have to scroll or swipe further every time you want to switch it on. MIUI lets you add, remove and reorder these quick settings tiles, but the edit option is easy to miss if you have never opened it before.
Enable Reading Mode in Mi Browser
Bright white pages in Mi Browser can strain your eyes during long reading sessions, especially at night. Xiaomi's reading mode swaps sharp whites for a warmer tone and dims contrast to reduce eye strain, but many people miss the intensity slider that controls how strong the effect actually is. Without adjusting it, the change can feel too subtle or too aggressive.
Allow or Deny Do Not Disturb Access for Apps
When an app suddenly enables Do Not Disturb on its own, or a call app keeps muting notifications you actually want to see, a hidden system permission is usually behind it. On Xiaomi phones, individual apps can request permission to switch Do Not Disturb on or off, and that access is not always obvious from the app itself. Checking which apps hold this permission helps you regain control over your notifications.
Set Touch & Hold Delay
If long-pressing an app icon on your Xiaomi home screen either opens the shortcut menu too fast by accident or takes too long to react, the touch and hold delay is set to the wrong stage. This timing controls how long you need to keep your finger down before a long-press action triggers, and it affects every control element that supports it, not just app shortcuts.
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.
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.
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.
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.
Change App Lock Password Type
If you set up App lock on your Xiaomi phone with a pattern and now want something faster or more secure, you are not stuck with that choice. The lock type you picked during setup can be swapped for a PIN or password at any time, without disabling App lock first.
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.
Email Guests From a Calendar Event
If an appointment reminder alone is not enough, guests often miss details or forget the event entirely. MIUI Calendar lets you send everyone attached to an event a custom email, but the app pre-selects all added guests automatically. Checking that list before sending prevents the message from going to the wrong people.
Add a New Contact
Saving a new phone number on a Xiaomi device sometimes feels confusing because the Contacts app hides extra fields like birthday, address or company behind a single Add button. Many users only enter a name and number, then wonder later why the birthday never shows up in the calendar. The trick is knowing which fields to expand before you save the entry.
Turn On/Off Emergency SOS
If your Xiaomi phone fires off an emergency text every time you grab it too fast, Emergency SOS is likely reacting to five quick presses of the power button. The feature sends your location and, if you choose, a summary of your last hour of call activity to selected contacts. Turning it off - or setting it up properly first - stops accidental alerts and unwanted location shares.
Export Contacts as a VCF File
Switching to a new phone or just backing up your address book can be tricky when the Contacts app on your Xiaomi phone does not offer a simple 'transfer' button. Instead, contacts leave the device as a VCF file, and picking the wrong storage location or account often means the file cannot be found afterward. Knowing where the export lands makes the difference between a working backup and a lost contact list.
Download Videos via Mi Browser
Saving a video from Facebook, YouTube or Vimeo on a Xiaomi phone usually means installing a separate downloader app first. Mi Browser can skip that step, but only if you know where the download option for links is hidden in the profile menu. Without it, a pasted video link just opens for streaming instead of saving to your storage.
Turn Camera Shutter Sound On or Off
Every photo on your Xiaomi phone triggers a shutter click, even in a quiet room or during a video call screenshot. The sound comes from the camera app itself and has nothing to do with your ringtone or notification volume, so muting the phone alone will not silence it.
Change Default Apps
If your Xiaomi phone keeps asking which app to use every time you open a song, a link, or a photo, no default app is set for that file type. MIUI stores these preferences per action, and once none is chosen, the selection prompt reappears every time you tap the file.
Turn Best Photo Marks On or Off
If your Gallery keeps flagging one photo out of a burst as the best shot, MIUI is comparing similar images and tagging the sharpest or best-exposed one automatically. Some users find this helpful for sorting large photo batches, others just want a clean gallery without extra labels. The setting controls whether this comparison runs at all.
