Turn Auto-download MMS On or Off
If picture or video attachments in text messages download automatically on your Xiaomi phone, MMS auto-download is turned on by default. This can eat through your mobile data plan fast, especially with large video files. Switching the feature off gives you control over when attachments actually get downloaded.
Allow or Deny Apps to Modify System Settings
Some apps on your Xiaomi phone quietly hold permission to change system settings like brightness, do-not-disturb or notification behavior, even after you stopped using them. If a random app is toggling display or sound settings on its own, this hidden permission is usually the cause. You can review and revoke it for individual apps without affecting others.
Turn On or Off the Pop-up Blocker
Banner ads and other pop-up windows keep breaking the flow of pages loaded in Mi Browser on Xiaomi phones. Turning off the pop-up blocker sometimes helps when a site relies on a pop-up window to show a login form, a coupon code or a download link that otherwise never appears. Switching it back on afterward keeps the ad clutter away again.
Turn Google Location History On or Off
If Google Maps keeps suggesting places based on where you have been, or your Timeline fills up with stops you never meant to save, Location History is still active in the background. On Xiaomi phones this tracking can run even when no Google app is currently open, which surprises a lot of users checking their data usage or battery drain.
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.
Set Monthly Data Usage Limit
If your Xiaomi phone still enforces the data limit from an old tariff, warnings or automatic data cut-offs can trigger at the wrong point in your billing cycle. The Monthly data limit value under Data usage does not update itself when your plan changes or your provider raises your allowance. You have to adjust it manually to match the new tariff.
Adjust Screen Brightness
If the display on your Xiaomi phone looks too dark indoors or blinds you at night, the brightness slider is set wrong or auto-brightness is fighting your manual changes. A screen running at full brightness all day is also one of the fastest ways to drain the battery. Getting the level right matters both for comfort and battery life.
Create a Contact Group
If you want to text several friends at once or hear a different ringtone when work calls versus family, MIUI needs your contacts sorted into groups first. Without a group, every message goes out individually and every caller sounds the same. Xiaomi handles this through a labeling feature inside the Contacts app that most people never notice.
Mirror Navigation Bar Buttons
If the back button and recent apps button feel like they are on the wrong side of the navigation bar, your Xiaomi phone likely has the default three-button layout active. Left-handed users especially notice this, since reaching for the back key on the left edge feels unnatural. A hidden toggle lets you flip the order of these two buttons without changing anything else on the home button.
Share Wi-Fi Password via QR Code
Typing out a long Wi-Fi password for every visitor gets tedious, especially with random letter-number combos. Xiaomi phones can turn your current network credentials into a scannable QR code instead. Anyone with a camera can then join the network without you dictating a single character.
Rename Face Data
If you have saved more than one face profile on your Xiaomi phone, for example a regular look and one with glasses, every entry shows up under the same generic label in the Face unlock settings. Without a custom name it is hard to tell which profile matches which appearance, especially when you only want to manage or delete one of them.
Manage Synced Gallery Albums
When Xiaomi Cloud sync is turned on, Gallery uploads every new photo and video automatically, including albums you would rather keep local. That fills up your cloud storage fast and makes it hard to tell which albums are actually being backed up. Instead of switching cloud backup off completely, you can review and adjust the sync status for each album on its own.
Auto-Update Download Settings
If your Xiaomi phone keeps downloading system updates in the background without asking, it can eat into your data plan or fill up storage at the worst moment. On the other hand, if updates never download automatically, you might miss important security patches for weeks. This behavior is controlled by a single toggle buried inside the MIUI version screen, separate from the mobile data download option next to it.
Delete a Conversation
Deleting a text thread one message at a time on a Xiaomi phone takes forever once a conversation has piled up over months. Long threads eat into storage and clutter your inbox, and most people never notice the shortcut MIUI offers for removing a whole conversation at once. Once you confirm the deletion, the messages are gone for good, so it helps to know exactly where to tap first.
Change the Always-on Display Clock Style
If the Always-on display on your Xiaomi phone only shows a plain digital number and you want something more analog or more detailed, the clock style is buried a few taps deep in the display settings. Many users never notice the option because it sits inside a submenu, not on the main Always-on display toggle screen. Picking the wrong style can also affect how much info fits on the lock screen and how visible the clock stays in daylight.
Send a Group Message (SMS/MMS)
When you try to text several people at once on a Xiaomi phone, it is not always clear whether picking multiple names in Contacts actually creates a real group thread. MIUI also switches silently between SMS and MMS depending on whether photos or long text are attached, so replies can end up scattered across separate one-on-one chats instead of a single conversation.
Turn MMS Read Receipts On or Off
If contacts can see the moment they read your MMS messages, or you cannot tell whether your own texts got opened, the read receipt option is likely misconfigured on your Xiaomi phone. This setting works separately from standard SMS delivery reports and needs its own toggle inside the messaging app. On Dual SIM devices, each SIM line can carry a different receipt setting, which often explains why the behavior seems inconsistent between conversations.
Turn On/Off Ad Blocker in Mi Browser
If ads keep interrupting your browsing or pages suddenly feel slower to load, the built-in ad blocker in Mi Browser is likely the reason. Xiaomi ships this filter active by default, similar to the pop-up blocker, and it can be switched on or off depending on how you want pages to render. Turning it off removes the filtering step but may bring back more banners and auto-play video ads.
Switch Between Front and Rear Camera
Selfies on a Xiaomi phone often need extra light, and the display flashes white to fake a camera flash for the front lens. If you are not sure where the switch control sits or why the screen behaves this way, jumping between front and rear camera during a quick shot or video call gets slower than it should. This affects both the Camera app and any third-party app that uses the same camera controls.
Turn Off TalkBack on Xiaomi
If your Xiaomi phone reads out everything you tap and single taps only select items instead of opening them, TalkBack is active. This screen reader changes how touch works across the whole system, which makes normal navigation confusing if you never meant to turn it on.
Turn On/Off Ascending Alarm Volume
If your Xiaomi alarm starts at full volume and jolts you awake instead of easing you into the morning, the ascending volume option is likely switched off. Some users prefer the opposite: a gentle ramp-up feels too quiet to wake them at all. Either way, this sits in a separate alarm setting that many people never notice.
Automatic App Updates Settings
If your Xiaomi phone only refreshes apps once it finds a Wi-Fi network, updates can lag behind for days when you are mostly on mobile data. This behavior comes from the Play Store auto-update setting, which defaults to Wi-Fi only on most Xiaomi devices. You can switch it to update over any network or turn automatic updates off completely.
Hide Notifications for Hidden Apps
If a hidden app on your Xiaomi phone still shows message previews on the lock screen or in the notification shade, anyone glancing at your phone can read what is inside. This happens because App lock only hides the app icon by default, not its incoming notifications. You can decide separately whether alerts from locked apps stay invisible until you open and unlock them.
Set the Action for When Your Data Plan Runs Out
If your mobile data suddenly stops working before the month is over, MIUI may already be cutting it off automatically once you hit your set limit. Some people only want a heads-up instead of losing their connection outright, but that only works if the right action is selected in the data usage settings. Without checking this setting, you can end up with dead mobile data at the worst possible moment.
