Turn Screen Wake for Notifications On or Off
If your Xiaomi phone lights up every single time a notification arrives, that constant flashing can drain the battery and get annoying fast, especially at night. On the other hand, if the display stays black and you only hear the notification tone, you might be missing messages you actually want to see right away. Both behaviors come from one single toggle in the lock screen settings.
Add a Birthday to a Contact
If the default Contacts form on your Xiaomi phone only shows phone number and email, there's no visible field for a birthday. That date option sits in a separate section that most people never open, so they assume it doesn't exist and skip it. Without it, you lose an easy way to keep birthdays tied directly to a contact card instead of a separate calendar entry.
Change Calendar View
If your Google Calendar app on Xiaomi always opens in Month view, finding today's appointments takes extra scrolling. The default layout does not match how you actually plan your day. Switching between Schedule, Day, 3-Day, Week and Month views fixes this without touching any system settings.
Remove a Stored Fingerprint
If a fingerprint still unlocks your Xiaomi phone after you sold it, handed it to someone else, or just registered a bad scan, that print needs to go. MIUI stores several fingerprints under one name, so it is easy to remove the wrong one by mistake. Deleting a print always asks for your unlock pattern, PIN or password first, which trips up people who only remember using their finger.
Resize a Home Screen Widget
When a widget takes up too much space or looks squeezed on your Xiaomi home screen, the easiest fix is adjusting its size instead of removing it. Not every widget supports resizing, and some only offer fixed size steps rather than free dragging. Knowing which widgets react to resize handles saves you from rearranging your whole layout.
Set Up Speed Dial for Calls
Dialing the same contact from a long list every time you need them wastes time when you only want to reach a favorite number fast. Speed dial on Xiaomi phones lets you call an assigned number with a single long press on the keypad, but it only works once a contact is linked to that digit. On Dual SIM devices you may also get asked which line to use if no default SIM for calls is set.
Remove a Member from a Contact Group
If a contact still shows up in a group even though you no longer want them there, the fix is not to delete the contact but to unlink them from that specific group. On Xiaomi phones this distinction confuses people because the removal option sits inside the group menu, not in the contact's own profile screen.
One-Handed Keyboard Mode
Typing with one thumb on a large Xiaomi screen often means missing keys on the far side of the keyboard. The stock layout stretches across the full display width, so you end up stretching your thumb or shifting your grip with every message. Xiaomi's keyboard settings can shrink and pin the whole layout to the left or right edge instead.
View Device Certification Info
If you need your Xiaomi phone's FCC ID, model number, or other certification details for a return, insurance claim, or customs check, they are not printed on the box or shown in a quick settings toggle. This information sits inside a dedicated certification screen that most users never open on their own.
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.
Check for System Updates
If you swiped away the update notification on your Xiaomi phone or never saw it pop up, the update itself is not lost. MIUI still tracks it in the background, you just need to trigger the check yourself. This matters when a security patch or bugfix has been sitting unnoticed for weeks.
Convert HEIF Photos to JPEG Before Sending
If photos shared from your Xiaomi phone show up as broken files or will not open on someone else's device, the picture was likely saved in HEIF format. Many apps and older phones cannot read HEIF directly, so the recipient sees a blank thumbnail or an error instead of your photo. The Gallery app has a setting that handles this conversion automatically at the moment you send a file.
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.
Turn On/Off USB Debugging
If MyPhoneExplorer refuses to sync contacts or a rooting tool cannot detect your Xiaomi phone over cable, USB debugging is usually still switched off. The option only appears once Developer options are unlocked, and many users cannot find the toggle afterward. Leaving it enabled permanently also carries a small security risk you should know about.
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.
Custom Image on Always-on Display
If the pre-installed Always-on Display themes on your Xiaomi phone all look the same, you can swap them for a photo of your own. MIUI lets you pick any image from your gallery instead of the default clock designs. Once applied, you can still adjust the clock position, text color, and how battery or notification icons appear on top of your picture.
Remove a Contact from Speed Dial
Speed dial slots on Xiaomi phones fill up fast, and once all numbers are taken you cannot assign a new one until an old entry is cleared. Removing a number from the list only deletes the shortcut, not the contact itself, but the option sits several menus deep inside the call settings and is easy to miss.
Clear RAM and Storage
If your Xiaomi phone feels sluggish or storage keeps filling up, junk files, app cache, and rarely used apps are often the cause. MIUI includes a built-in cleanup tool that clears RAM and storage in one pass, but what actually gets removed depends on which categories you select before confirming.
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.
Restart the Xiaomi Smartphone
If apps on your Xiaomi phone start lagging, background downloads get stuck, or the interface feels sluggish after days of uptime, a restart usually clears the problem. MIUI keeps processes and cached data running in the background, and over time this can slow down the whole system. A clean reboot forces MIUI to close every open app and rebuild its memory from scratch.
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.
Turn Off Battery Saver Automatically After Charging
If Battery saver stays active even after your Xiaomi phone finishes charging, it keeps throttling performance and dimming the screen longer than needed. MIUI can switch Battery saver off on its own once the battery reaches a set charge level, so you don't have to remember to disable it by hand every time you unplug the charger.
Stay on Lock Screen After Face Unlock
If your phone jumps straight to the home screen after face unlock, you lose the chance to glance at notifications or widgets on the lock screen first. Other users want the opposite and prefer to land on the home screen right away without an extra tap. This behavior comes from a single toggle hidden inside the Face unlock settings on your Xiaomi phone.
Switch Recent Apps View
On Xiaomi phones, Recents stacks open apps vertically below each other by default, which can feel cramped if you are used to the classic card layout. MIUI lets you switch to a horizontal row instead, so apps line up side by side like in older Android versions. This setting sits in the Home screen options, not inside the multitasking menu itself.
