Change Camera Photo Frame Ratio
Photos taken in the default 4:3 frame show black bars when you stream them to an HDTV or play them back on a widescreen display. Switching to a 16:9 ratio matches modern screens and avoids the letterboxing, while a 1:1 crop works better for square social posts. The frame setting sits in the camera menu and is easy to miss if you never open it.
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.
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.
Double Tap to Wake or Sleep Screen
Waking your Xiaomi phone only works by pressing the power button, and double-tapping the display does nothing. This happens when 'Double tap to wake or turn off screen' is switched off in the lock screen settings, so a quick glance at the clock or notifications requires a full button press instead.
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.
Switch Between Navigation Buttons and Gestures
If your Xiaomi phone shows on-screen Back, Home, and App Toggle buttons but you expected full-screen swipe gestures - or swipes stopped registering and buttons appeared instead - the system navigation mode has switched. This setting decides whether MIUI runs on three buttons or edge-to-edge gestures, and mixing up the active mode leads to missed taps or swipes that do nothing.
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.
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.
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.
Assign Custom Button Shortcuts
If double-pressing the power button always opens the camera when you wanted a screenshot instead, the button shortcut linked to that gesture doesn't match how you actually use your phone. MIUI lets you remap gestures like double-press power or long-press volume to actions such as torch, split screen or Google Assistant. Finding and changing that mapping means digging through a settings menu that isn't obvious at first glance.
Change Color Scheme
If photos, videos or app icons on your Xiaomi phone look washed out or overly intense, the display color scheme is likely set to the wrong profile. MIUI lets you switch between a natural, a vivid and a standard color rendering, plus fine-tune the color temperature manually. Picking the wrong option can make skin tones look off or colors appear flat.
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 Call Waiting On or Off
If you are already on a call and a second call comes in on your Xiaomi phone, a tone and a pop-up usually appear. When Call waiting is switched off, that second caller hears a busy signal instead and nothing shows up on your screen. With Dual SIM, this setting applies per SIM card, so one line can behave differently from the other.
Turn Camera Grid Lines On or Off
If your photos keep coming out tilted or the horizon never lines up straight, you are probably shooting without any framing guide. Xiaomi's camera app can overlay a 3x3 grid that helps you keep verticals upright and place the horizon on a clean line. Without it, minor tilts are easy to miss on a small screen and only show up later when you check the shot on a bigger display.
Add Account in Calendar App
If appointments from your Google or work account never show up in the Xiaomi Calendar app, only one account is usually linked to it. Calendar only displays events for accounts you have added yourself, so a new work email or a second Google account stays invisible until you connect it. This is also why events vanish after switching phones or resetting the calendar app.
Change Camera Picture Quality
If your camera storage fills up fast or photos take too long to share, the picture quality setting in the MIUI camera app is often the reason. Xiaomi's camera defaults to a high resolution that produces large files, even when you only need a quick snapshot. Switching between High, Standard, and Low lets you balance sharpness against file size for each situation.
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.
Disable Navigation Bar Per App
Accidentally tapping the Back or Recents button during a full-screen game or video can pull you out of the app at the worst moment. On Xiaomi phones the on-screen navigation bar stays active by default even in apps that do not need it. MIUI lets you set this behavior per app instead of turning it off system-wide.
Turn On/Off Traffic Mode
If a background download eats up bandwidth while you are streaming or on a video call, your Xiaomi phone might be sharing the connection equally between all apps. Traffic mode in the Wi-Fi assistant lets you decide whether the app you are actively using gets priority over background traffic. Without it enabled, downloads and updates can slow down whatever you are doing in the foreground.
