Auto-download Updates via Mobile Data
If your Xiaomi phone keeps pulling system updates in the background while you are off Wi-Fi, mobile data usage can climb fast without warning. MIUI treats update downloads as automatic once a new version is detected, and a separate toggle decides whether mobile data counts as an allowed source for that download. Switching it off limits update downloads to Wi-Fi only, which matters if you are on a limited plan.
Send Photos and Videos via Bluetooth
Sending a photo or video from your Xiaomi phone to a paired device sometimes stalls right after you tap Share, or the target device never shows up in the list. This usually comes down to picking the wrong sharing option or Bluetooth pairing not being active. The steps below use MIUI's file sharing menu, which works the same for pictures, videos and most other file types.
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.
Snooze App Notifications
When a chat app or delivery tracker keeps buzzing during a meeting, muting it completely isn't always what you want. MIUI lets you pause a single notification for a set time instead of turning it off for good. This keeps the alert coming back later without touching the app's notification settings.
Configure Individual System App Settings
When Security, Messages, or Camera on your Xiaomi phone keeps auto-updating or asking for permissions you never approved, a hidden per-app toggle in System app settings is usually the cause. Each preinstalled MIUI app, from Calendar to Recorder, carries its own switches for updates, notifications, and background data that do not show up on the regular app info screen. Finding the right toggle for the right app is the only way to fix the behavior without disabling the whole app.
Set Up a Portable Wi-Fi Hotspot
If your Xiaomi phone still hands out a hotspot name and password nobody chose, other people nearby can guess it or connect without permission. A weak default SSID also makes it harder to spot your own hotspot among several devices in the same room. Setting a custom name and password fixes both problems and keeps the connection under your control.
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.
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.
Turn Off Wi-Fi and Bluetooth Scanning for Location
Even with Wi-Fi and Bluetooth switched off, your Xiaomi phone can still scan nearby networks and devices to sharpen its location fix. Apps with location permission trigger this background scanning automatically, keeping your radios active more often than expected. If you want tighter control over when your phone searches for networks, the scanning setting needs to be adjusted separately from the Wi-Fi and Bluetooth toggles.
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.
Back Up Phone Data to Google Drive
If your Xiaomi phone gets reset, lost or swapped for a new one, contacts, messages and app data disappear unless a backup exists somewhere else. MIUI has a built-in option to save that data to Google Drive, but the toggle sits buried in the general settings and is easy to miss until you actually need it.
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 On App Lock
If anyone can open your banking, messaging, or gallery apps just by unlocking your phone, sensitive content stays exposed. Xiaomi phones include a separate app-level lock that adds a second layer of protection on top of your screen lock. Setting it up wrong, or skipping the fingerprint option, often leaves some apps unprotected.
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.
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.
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.
Mark Contact as Favorite
If a contact you call or message often gets buried in a long list, you probably haven't set it as a favorite yet. Favorites move straight to the top of the Contacts app and speed up dialing from the Phone app. It's a quick toggle, but easy to miss since it's tucked inside the contact detail view.
Show Emojis in the Symbols Keyboard
On Xiaomi phones the symbols keyboard can display your most recently used emojis for quicker access, but that suggestion strip stays hidden by default. The Mi keyboard needs this behavior turned on separately before recent emojis appear next to the symbols and numbers.
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.
Rename a Paired Bluetooth Device
When several Bluetooth accessories are paired to your Xiaomi phone, the device list can quickly fill up with cryptic model numbers or partial MAC addresses. Telling a pair of earbuds apart from a car stereo or a fitness tracker gets difficult once the default names look identical. Renaming each paired device gives you a clear label instead of guessing which entry belongs to which gadget.
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 Camera Live Tips
If your Xiaomi camera keeps popping up messages about a dirty lens or telling you to hold the phone level, the Live tips feature is running in the background. These prompts are useful for beginners but can get in the way during fast shooting, and not everyone wants every single tip active.
