Turn On/Off Auto Brightness
If your Xiaomi screen keeps getting brighter or dimmer without you touching anything, Auto Brightness is reacting to the light sensor. You can still drag the brightness slider manually while the function stays active, which often causes confusion about which setting is actually in control.
Turn Off Developer Options
If Developer options keeps popping up in your Xiaomi settings even though you only enabled it once for a quick fix, it usually just needs to be switched off inside its own menu. Leaving it active keeps USB debugging and other low-level toggles exposed, which can interfere with app checks or banking apps. Turning it off hides the whole menu again until you reactivate it through the hidden tap sequence.
Shake to Auto-Arrange Home Screen Icons
Empty cells scattered across your Xiaomi home screen after uninstalling an app? Shaking the phone while in edit mode can pull the remaining icons together and close those gaps automatically. The feature, called Shake to fill empty cells, sits hidden in the display settings and can be switched on or off.
Split Screen on Xiaomi Phones
Split screen lets you run two apps side by side on your Xiaomi phone, so you can chat while browsing or take notes while watching a video. MIUI offers more than one way to trigger it, and not every app supports it the same way. Knowing how it behaves helps you decide when it actually saves time.
Turn Automatic Date & Time On or Off
If your Xiaomi phone shows the wrong time after a trip or SIM swap, the automatic time sync is likely still active. Automatic date & time relies on network-provided time, which can lag or fail when signal is weak. Turning it off lets you set the clock manually instead.
Missed Call Reminders: Turn On or Off
If a missed call slips by unnoticed until hours later, missed call reminders are probably switched off or set to repeat only once. MIUI can nudge you again about an unanswered call, and the number of repeats is adjustable. Without this setting active, a single missed call notification is easy to swipe away and forget.
Lock Home Screen Layout
If icons keep shifting position every time you delete an app or accidentally shake your phone, MIUI is still rearranging empty spaces on its own. Locking the layout stops that automatic reshuffling and keeps every icon exactly where you placed it.
Turn Auto-Sync Data On or Off
If your Xiaomi phone burns through mobile data or drains battery faster than expected, background account synchronization is often the reason. This setting keeps your Google Account data, like contacts, calendar entries and photos, updated in the background at all times. Switching it off stops the drain immediately but also means new changes stop arriving until you sync manually.
Turn Tap Sounds On or Off
Every tap on a button, the Back key, or a menu item triggers a short click sound on your Xiaomi phone. If that noise gets distracting during calls, meetings, or at night, the Tap sounds setting is behind it and can be switched off just as quickly as it can be turned back on.
Restrict Mobile Data Usage for an App
If a Xiaomi phone burns through your data plan even though you barely open certain apps, background data access is usually the cause. By default every installed app can use mobile data and Wi-Fi without restriction. On dual-SIM phones this applies separately to each SIM slot, which makes it harder to spot which line is actually consuming the data.
Edit and Rearrange Quick Settings
If the toggle you need most sits at the bottom of the control center or is missing entirely, you have to scroll or swipe further every time you want to switch it on. MIUI lets you add, remove and reorder these quick settings tiles, but the edit option is easy to miss if you have never opened it before.
Turn Contact Sharing via Bluetooth On or Off
When you pair your Xiaomi phone with a car radio, the contact list sometimes stays empty even though the Bluetooth connection shows as active. That happens because MIUI keeps Contact sharing separate from the general Bluetooth toggle, so voice dialing and steering-wheel controls have no phonebook to pull from until you enable it. The same setting can also keep sharing your address book with a paired device after you no longer want it to.
Set Touch & Hold Delay
If long-pressing an app icon on your Xiaomi home screen either opens the shortcut menu too fast by accident or takes too long to react, the touch and hold delay is set to the wrong stage. This timing controls how long you need to keep your finger down before a long-press action triggers, and it affects every control element that supports it, not just app shortcuts.
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.
Change App Lock Password Type
If you set up App lock on your Xiaomi phone with a pattern and now want something faster or more secure, you are not stuck with that choice. The lock type you picked during setup can be swapped for a PIN or password at any time, without disabling App lock first.
Change SIM PIN
The PIN that comes preset on a new SIM card is rarely one you can memorize, and typing the wrong code repeatedly locks the card. On Xiaomi phones you can swap it for a PIN you actually remember, but the option sits a few menus deep under network security settings rather than in the main lock screen settings.
Restore a Local Backup
If you deleted an app or lost data on your Xiaomi phone, you don't need a full factory reset to get it back. MIUI keeps local backups separate from Google and Xiaomi Cloud backups, and picking the wrong one often leaves apps or settings missing. Knowing which backup type actually contains your data saves time before you start the restore.
Export Contacts as a VCF File
Switching to a new phone or just backing up your address book can be tricky when the Contacts app on your Xiaomi phone does not offer a simple 'transfer' button. Instead, contacts leave the device as a VCF file, and picking the wrong storage location or account often means the file cannot be found afterward. Knowing where the export lands makes the difference between a working backup and a lost contact list.
Turn On/Off Auto-Update
If your Xiaomi phone keeps installing system updates overnight without asking, or you never get notified when a new MIUI version is ready, the auto-update setting is likely working against you. Some users want updates to install by themselves while they sleep, others prefer full control before anything changes on the device. This setting decides which of the two happens.
Schedule Dark Mode Automatically
Switching dark mode on and off every day by hand gets tedious, especially when you only want it active at night. Xiaomi phones can handle this automatically, but the scheduler sits right next to the regular dark mode switch and is easy to miss. Without setting a start and end time, the display keeps whatever theme you last picked instead of changing on its own.
Share a Contact via Message or App
Retyping a phone number into a text message often introduces errors, especially with long international formats. On Xiaomi phones, the Contacts app lets you send a person's saved details directly through messaging or email without typing anything manually. This keeps every field intact and avoids typos on both sides.
Delete Photos or Videos from Gallery
Storage on your Xiaomi phone fills up fast once photos and videos pile up in the Gallery app. Many users don't realize they can select several items at once instead of deleting them one by one. This guide covers the exact steps to clear out unwanted media quickly.
Change the Time Zone Manually
If your Xiaomi phone keeps switching its time zone whenever you travel or connect to a different carrier network, automatic time zone detection is the cause. This network-based setting overrides any manual change you make until you turn it off. Once you know where that toggle sits, you can lock in a fixed time zone yourself.
Quick Ball Shortcuts and Behavior Settings
If the floating Quick ball only opens one fixed app or keeps popping up during video playback, its behavior settings are still on default. MIUI lets you change the trigger gesture, auto-hide rules and screen position, but these options sit outside the shortcut list and get overlooked easily.
