Assign Google Assistant to the Power Button
On some Xiaomi phones a short press of the Power button opens the power menu instead of Google Assistant, even though full screen gesture navigation is active. This happens because the button shortcut for Google Assistant sits in a separate settings section and stays off by default. Without enabling it, you still need the home button gesture or voice command to wake the Assistant.
Schedule Power On/Off
If you keep forgetting to switch your Xiaomi phone off at night or want it ready and running before you even reach for it in the morning, pressing the power button every time gets old fast. MIUI includes a built-in scheduler that turns the device on and off at fixed times you define, with support for daily repetition or custom days. Once set up, the phone handles the switching on its own, without any manual input.
Turn On or Off Reading Mode
If your Xiaomi phone throws a cold, blue-tinted glow at night, reading on it can feel harsh and even keep you awake longer. Reading mode warms up the display colors to ease eye strain, but a lot of people never find the toggle or the scheduling option. Without it set up correctly, the warmer tone never kicks in on its own when you need it.
Change Home or Lock Screen Theme
If your Home screen, Lock screen, and app icons suddenly look inconsistent after switching themes, MIUI applied only part of the new theme's assets. This happens when a saved theme only covers some elements, like Lock screen and System, but skips Icons. Picking the wrong theme ('Classic' vs 'Limitless') or a corrupted download can also leave icons untouched while wallpapers change.
Turn Wi-Fi On or Off
If your Xiaomi phone won't connect to your home or public network, Wi-Fi might simply be switched off in the background. Leaving Wi-Fi active around the clock also drains the battery faster, especially when no network is in range. Many users struggle to find the toggle after a system update moved it inside a different menu.
Sort Contacts by First or Last Name
If your Xiaomi contact list feels out of order, it usually comes down to whether the Contacts app is sorting entries by first name or last name. This becomes a real problem when you are searching for someone by their surname but the list is alphabetized by given name instead. The rule that controls this sits in one setting inside the Contacts app.
Manage the Personal Dictionary
If your keyboard keeps autocorrecting a name, brand term, or slang word you actually want to type, MIUI's personal dictionary is the setting that controls this behavior. Without an entry there, the keyboard falls back to its built-in wordlist and ignores your preferred spelling or shortcut for longer phrases.
Document Scanner Shortcut: Enable or Disable
If the camera keeps popping up a scan icon every time you point it at a sheet of paper or a presentation slide, the Document scanner suggestion is active. Some people find this shortcut useful for quickly digitizing paperwork, others just want the extra button gone from the viewfinder.
Wi-Fi Assistant: Select Best Networks Automatically
If your Xiaomi phone keeps switching away from a weak Wi-Fi network without asking, Wi-Fi assistant is likely doing that for you. Once every nearby network drops in signal, it can also fall back to mobile data on its own, which can use up your data plan faster than expected. This automatic switching can also cause interruptions during video calls or downloads.
Turn On/Off Wi-Fi Calling
Weak signal at home, underground, or in a concrete building often causes dropped calls on a Xiaomi phone, even when Wi-Fi shows full bars. Wi-Fi calling routes voice calls through your wireless network instead of the mobile network, but only works if your carrier actually supports it. If the toggle is missing from your SIM settings, an unsupported plan or outdated carrier profile is usually the reason.
Turn Off User Experience Program
If usage statistics keep syncing quietly in the background on your Xiaomi phone, the User Experience Program is likely still active. This service sends anonymous usage data from your device to Xiaomi to help refine products and features. Since it is not possible to verify exactly what data leaves your device, disabling this option is the safer choice.
Turn Do Not Disturb On or Off
When Do Not Disturb is active on your Xiaomi phone, calls get an instant busy signal and every notification stays silent, even for messages you actually want to hear. Many people leave it on by accident after enabling it for a meeting or at night, since MIUI does not always show a clear reminder that it is still running. Checking the current status and switching it off takes just a few taps in Sound & vibration settings.
Change Device Name
If your Xiaomi phone still shows up under its model number when you scan for Bluetooth devices or connect to a hotspot, that is the default device name at work. It makes picking your phone out of a list of nearby devices harder, especially if you own more than one Xiaomi device. MIUI lets you replace that generic label with a name you actually recognize.
Unhide an Album in Gallery
If a photo album you hid earlier is missing from Gallery, it is not deleted - it just sits in a separate hidden section. Xiaomi keeps hidden albums out of the main view until you unhide them again, and each album needs to be restored on its own.
Show or Hide the Emoji Switch Key
If you type a lot of emojis, switching between the language globe and the emoji picker can slow you down on the MIUI keyboard. The globe icon and the emoji key share the same spot, so only one of them shows on the keyboard row at a time. Turning on the emoji switch key swaps that icon while quick language switching still works by holding the space bar.
Turn Screen Cast On or Off
If your Xiaomi phone won't mirror to a TV or monitor, the built-in Cast feature might be turned off, or your phone and screen aren't on the same Wi-Fi network. Screen Cast behaves differently from many third-party mirroring apps, since playback usually stops the moment you turn off the display. That makes it easy to mistake a disabled toggle for a broken connection.
Change Alarm Tone
If your Xiaomi alarm keeps ringing with the same generic tone or the Nature alarm sound never changes, the ringtone categories in the Clock app are likely the reason. Some categories, like Nature alarm, only rotate through different sounds when the phone has an active internet connection. Without that connection, the alarm falls back to a stored default tone instead of downloading a new one.
Allow Gallery Access to SD Card
If Gallery on your Xiaomi phone refuses to save new photos or won't let you delete files on the SD card, it usually means storage access was never granted. Android blocks apps from writing to external storage until you confirm the permission for that specific card. Until you approve it, Gallery can only display existing files but not create, move or remove anything on the card.
Turn Web Link Previews On or Off
If URLs in Xiaomi Messages show up as plain text instead of a preview card, the Automatic previews option is likely set to a mode you did not expect. MIUI lets you choose between previews for every shared link, previews limited to web addresses, or no previews at all. This affects both how conversations look and how much data the app pulls in the background.
Remove Google Search Bar from Home Screen
After the first setup of a new Xiaomi phone, a Google Search bar sits on the home screen by default and takes up space you might want for widgets or app icons. Many people assume it is a fixed part of MIUI and leave it there without checking. It is actually just a removable widget, so getting rid of it does not require digging through any settings menu.
Connect to Wi-Fi Using a QR Code
Typing out a long Wi-Fi password on a Xiaomi phone gets tedious, especially with mixed case letters and symbols. If the network owner has a QR code ready, you can skip the password field entirely by scanning it with the built-in Wi-Fi scanner.
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.
Turn Battery Drain Notifications On or Off
If your Xiaomi phone keeps popping up alerts about fast battery drain, or you never get one and expect to, this setting is the reason. Battery drain notifications warn you when an app or background process burns through power faster than normal. Left enabled, unrelated background tasks can trigger these alerts more often than you would like.
Change Keyboard Theme (Language & Input)
If the Gboard keyboard on your Xiaomi phone still shows the default gray background, the theme setting has never been switched. This only changes the visual layout - colors, gradients or picture backgrounds - and has no effect on autocorrect or typing speed. The key borders can also be turned on or off separately from the overall theme.
