Change Time Format
If your Xiaomi phone shows time in a format you did not choose, MIUI is likely following your system language setting automatically. This means the clock can jump between 12-hour and 24-hour display whenever you change language or region. You can lock the format manually so it stays consistent no matter what language MIUI is set to.
Keyboard Vibration Settings
If every tap on the on-screen keyboard triggers a buzz that feels too strong or too weak, or typing feedback vanished after an update, the keyboard's Haptic feedback on keypress setting is usually the cause. This option runs independently from your general system vibration, so toggling System vibration alone will not fix it. Notifications and Focus mode profiles do not touch this setting either, since it lives inside the keyboard app itself.
Add a Time Stamp to Photos
Photos taken with your Xiaomi phone often show no date or time, making it hard to prove exactly when a picture was captured. This is controlled by the Watermark option inside the Camera app, which stays off by default on most MIUI devices. Without it enabled, every shot leaves the gallery without any timestamp overlay.
Show SIM Card Messages
Old text messages from years back sometimes stay on the SIM card instead of moving into the phone's internal storage. If you swap the SIM into a new Xiaomi phone, those messages do not show up in your normal inbox automatically, so it looks like they are gone.
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.
Set Data Usage Warning Level
If you have already capped your monthly data plan on a Xiaomi phone, you might still get surprised when the limit hits without any heads-up. The warning level tells MIUI at what percentage of your data plan it should alert you before you run out.
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.
Delete an Alarm
If your Xiaomi phone keeps ringing at a time you no longer need, an old alarm is probably still sitting in the Clock app. Alarms pile up quickly once you set them for one-off events like flights or workouts, and they rarely get removed afterward. A cluttered alarm list also makes it harder to spot the one alarm you actually rely on every morning.
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.
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.
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.
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.
Sound and Vibration for Calendar Reminders
If birthday or appointment reminders in the Calendar app stay silent, or if they buzz and ring when you would rather have them quiet, the notification settings for that app are usually the cause. On Xiaomi phones this is controlled separately from the general system sound, so a muted phone does not automatically mean the calendar stays quiet too. Checking the dedicated Calendar notification options clears up most missed or unwanted reminder alerts.
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.
Remove a Home Screen Widget
A widget that once seemed useful can quickly become clutter on your Xiaomi home screen. Outdated info panels, oversized widgets, or ones that constantly refresh data in the background all eat into space and battery life. If a widget no longer earns its spot, getting rid of it is worth doing before it wastes more resources.
Clear the Whole Call History
When missed, dialed, and received calls pile up on your Xiaomi phone, scrolling through the list to find one number gets tedious fast. Deleting entries one at a time barely makes a dent if you actually want a clean call log. MIUI offers a single action that wipes the entire history at once, and once it's gone, it's gone for good.
Format an SD Card
A newly inserted SD card sometimes won't work correctly in a Xiaomi phone, or you want to wipe an old card before reusing it. Formatting clears the card and lets MIUI set up the folder structure it needs to store photos, videos and app data properly. Once you confirm the format, every file on the card is gone for good.
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.
Enlarge the Mouse Pointer
When you plug a USB mouse or similar pointing accessory into a Xiaomi phone, the on-screen pointer often stays tiny and hard to track. Large mouse pointer is a dedicated Accessibility option built for exactly this situation, especially useful for anyone with limited vision. Without enabling it, you end up guessing where the cursor sits on a crowded screen.
Pocket Mode in the Camera App
If your phone's camera keeps opening or snapping photos while it's still in your pocket, stray touches on the screen are usually the cause. Pocket mode locks the touchscreen once the sensor detects the phone is stored away, blocking accidental swipes and taps. When the camera reacts to pocket movement or the screen stays unresponsive after you pull the phone out, this setting is worth checking.
