App Download Preference (Play Store)
If apps on your Xiaomi phone start downloading over mobile data even while connected to Wi-Fi, the Play Store's download preference is likely set to Over any network. This setting decides whether new app installs and updates use any connection, Wi-Fi only, or ask before each download. Getting it wrong quickly eats into a limited monthly data plan.
Delete a Contact
Contacts opened from Calls or Messages on a Xiaomi phone are the same entries stored in the Contacts app, so removing one wipes it out everywhere at once. Syncing with your Google Account does not stop the local delete from going through, and once it is confirmed there is no built-in way to bring the entry back.
Block Offensive Words in Keyboard Suggestions
If the keyboard on your Xiaomi phone keeps suggesting swear words or curses while typing, autocorrect is picking them up as valid entries. A dedicated filter in the keyboard settings controls whether these words show up in suggestions at all. Turning it on or off changes what the prediction bar offers, not what you can actually type.
Assign a Contact to a Speed Dial Number
If holding down a number on the dial pad does nothing on your Xiaomi phone, no contact has been linked to that speed dial slot yet. Speed dial only works once you connect a number manually to a saved contact. Without that step, the quick dial button stays empty and no call goes through.
Remove a Linked Account
If chats, photos or documents suddenly disappear after cleaning up accounts on your Xiaomi phone, the sync connection for that account was likely removed rather than just logged out. Google, WhatsApp, Facebook and similar accounts all sit under the same accounts module, and removing one can wipe locally cached data tied to it. Knowing which account type you are touching matters before you tap confirm.
Data Usage Warning on Lock Screen
If you blow through your mobile data plan before the billing cycle ends, you probably only find out when the carrier sends a throttling notice. Xiaomi phones can flag this earlier, but the lock screen warning for data usage is off by default on most devices. Without it enabled, you only see usage numbers if you open the Security app yourself.
Turn On/Off Always-on Display
If your Xiaomi screen stays completely black in standby, you might be missing the time, battery level, or notifications at a glance. This depends on the Always-on display feature, which only works on Xiaomi models with an OLED panel, not on LCD screens.
Clear App Cache
If an app on your Xiaomi phone keeps crashing, freezing, or throwing error messages, leftover cache files are often the reason. Over time these temporary files pile up and can overlap or corrupt each other, causing an app to behave oddly even though nothing else changed. Clearing the cache removes that clutter without touching your saved data or settings.
Fingerprint Unlock for App Lock
If a locked app on your Xiaomi phone keeps asking for the app lock password even though your fingerprint sensor works everywhere else, fingerprint unlock for App lock is probably switched off. This setting lets you skip the PIN or pattern entry for individual apps and confirm access with your finger instead. Without it enabled, MIUI falls back to the password every time you open a protected app.
Camera Delay-Timer
If your Xiaomi camera fires the shutter the instant you tap the button, group photos or selfies often turn out blurry or catch you mid-pose. MIUI has a built-in delay-timer for exactly this situation, but it sits hidden inside the camera menu instead of the main shooting screen. Without it, you only get a split second to get into position before the shot is taken.
Enable or Disable Spell Check
If words get underlined the moment you type them on your Xiaomi phone, spell check is active in the keyboard. Unlike autocorrect, spell check only flags a word as wrong without changing it, which can feel distracting when you type quickly or use slang. You can turn this marking on or off separately from autocorrect.
Delete a Folder from the Home Screen
A folder that still holds one or two apps refuses to disappear no matter how often you tap on it. MIUI does not offer a direct delete button inside the folder itself, which confuses a lot of users. The trick lies in how you grab and move the folder icon, not in emptying it app by app.
Enable or Disable Simple View for Contact List
If your contact list on your Xiaomi phone feels cluttered with profile pictures and extra info, a simple list view can clean things up. This setting in the Contacts app controls whether photos and details show up next to each name, or whether you just get plain text entries. Switching it off makes scrolling through a large contact list faster and less distracting.
Turn On/Off Screen Magnification
If icons, text or app menus stay too small even after adjusting the display size, the built-in screen magnifier can help. On Xiaomi phones this feature works as a temporary zoom you trigger with a gesture or a shortcut button, not as a permanent font size change. Many users enable it but then struggle to find the toggle again or accidentally leave it running in the background.
Show or Hide Notification Icons in the Status Bar
When your status bar stays empty even though an app has new messages, the notification icon display in MIUI might be switched off. This setting decides whether small app icons show up next to the clock so you can spot new activity without unlocking your phone. If it is disabled, you will only notice new notifications once you pull down the shade.
Add a Bookmark to the Home Screen
If you keep opening Mi Browser just to reach one saved website, that link only lives in your bookmarks list, not on the home screen. Xiaomi phones do not turn a saved bookmark into a shortcut automatically, so you have to add that icon yourself. Without it, every visit means opening the browser, tapping Bookmark, and scrolling to find the right entry.
Delete an APN Entry
A wrong or duplicate access point can block mobile data or MMS on your Xiaomi phone, even after you switch carriers or SIM cards. If an old APN profile stays behind, the device sometimes keeps trying to use it instead of the correct one. Removing the unused entry clears up the confusion without touching your other network settings.
Turn On/Off Color Correction (Accessibility)
If someone using your Xiaomi phone has trouble distinguishing colors in charts, status icons, or notification dots, the screen's color rendering may need adjusting for a vision deficiency like red-green color blindness. MIUI ships with a color correction filter built into the Vision accessibility tools, but it stays disabled by default and is easy to miss. Without it turned on, the display keeps showing standard colors that are hard to tell apart for certain types of color vision anomalies.
Delete a Contact Group
If a contact group in the Xiaomi Contacts app is cluttering your groups list, you can remove it without losing the people inside it. Many users hesitate because they assume deleting a group also deletes the assigned contacts. In reality, only the group label itself gets removed, while every contact stays saved on the device.
Turn On Automatic Backup for Storage and Data
If you only remember to back up your Xiaomi phone after something breaks or gets lost, relying on manual backups is the real problem. MIUI can schedule backups on its own, but the default days, time, and data selection may not match how you actually use your phone. Getting the schedule wrong means backups either pile up unnecessarily or miss the files you actually care about.
Set a Custom Timer Ringtone
If the timer on your Xiaomi phone keeps playing the same generic tone, you probably want something you actually notice - or one you can tune down for lighter naps. MIUI lets you swap the timer sound for a pre-installed ringtone or your own .mp3 file, but the option sits several taps deep inside the Clock app and is easy to miss. Picking the wrong file type can also mean silence instead of a sound.
Pin a Conversation
If an important chat keeps sliding down your conversation list on a Xiaomi phone, new messages from other contacts push it out of view. The Messaging app sorts threads by recent activity, so a conversation without fresh replies eventually disappears from the top. Pinning keeps that specific chat visible regardless of how much new activity happens elsewhere.
Disable Wi-Fi Direct
On many Xiaomi phones the Wi-Fi Direct toggle looks greyed out or simply refuses to switch off. That happens because the feature stays active as long as at least one device remains paired to it. Disconnecting every paired device is the only way to actually shut Wi-Fi Direct down.
Limit Connected Hotspot Devices
By default, your Xiaomi phone lets an unlimited number of devices join your mobile hotspot at once. That can slow down your connection and makes it hard to track who is actually using your data. Setting a maximum device count gives you back control over who connects.
