Notifications & Focus

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.

Change Select to Speak Voice Output

If Select to Speak reads text too slowly or sounds flat, the text-to-speech engine behind it is still running on its default speed and pitch. MIUI lets you fine-tune the speaking rate, voice pitch and language instead of leaving Select to Speak untouched. A wrong accent or a voice that talks too fast points to the same settings screen.

Turn Flashlight On or Off

Need to switch on the LED flash on the back of your Xiaomi phone without opening the camera app? The flashlight toggle sits in the quick settings panel, but if you rarely use it the icon is easy to overlook. An unresponsive toggle usually points to a Control center layout change, not a broken LED.

Turn On/Off Device Watermark on Photos

Every photo you take with your Xiaomi phone gets a small watermark in the bottom left corner, showing which device captured the shot. If you want cleaner images for sharing or printing, that watermark can get in the way fast.

Network & Connectivity2

Pair a Bluetooth Device

If your headset, earbuds, or speaker will not connect to your Xiaomi phone, the accessory usually needs to be paired first before Bluetooth can use it. Until pairing finishes, the phone will not list it as an active connection, so audio and calls stay on the built-in speaker.

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.

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.

Mobile Data on Secondary SIM During VoLTE Calls

When you're on a VoLTE call with your primary SIM, mobile data can stay locked to that same line instead of switching to your secondary SIM. That leaves apps stuck loading or messages stuck sending mid-call. A dedicated toggle in the network settings decides which SIM handles data traffic while a VoLTE call is active.

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.

Turn Select to Speak On or Off

If Select to Speak stays greyed out or its icon never shows up in your navigation bar, the accessibility shortcut on your Xiaomi phone is probably still switched off. Once enabled, tapping the icon lets you select any text or image on screen and have it read aloud instantly. Turning it off again removes the icon without touching other accessibility settings.

Make a Phone Call

When two SIM cards are active on your Xiaomi phone, tapping the call button can leave you unsure which line actually dials. The Phone app splits the green call button into two halves, one per SIM, and tapping the wrong side sends the call out on the wrong number or tariff. This mix-up gets worse if the SIM slots have not been renamed, since both halves look nearly identical.

Forward an SMS Message

Need to pass on an address, code, or phone number from a text without retyping it? On Xiaomi phones you can forward the original SMS straight from the Messages app instead of copying the content by hand. This saves time and avoids typos in important details.

Set Always-on Display Duration

If your Always-on display only flashes for a few seconds after you tap the screen, it is set to the short timer instead of staying on permanently. On MIUI you can choose between a brief 10-second preview and a version that stays active the whole time your phone is locked or in standby.

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.

Delete an Event in the Calendar App

If your calendar is cluttered with old appointments you no longer need, deleting individual events keeps things readable. Once removed, an event is gone for good and cannot be restored. On some Xiaomi phones the built-in Calendar app is replaced by Google Calendar, which uses a slightly different menu.

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.

Photo, Video & Media

Show Only Local Albums in Gallery

If your MIUI Cloud stores thousands of photos, the Gallery app can end up cluttered with albums that only exist online and were never saved to your phone. Turning on Only show local albums hides those cloud-only entries so you see just what is actually stored on the device. This helps when storage is tight or the Gallery feels slow to load.

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.

Add a Widget to the Home Screen

Opening an app just to check a stock quote, the weather, or your next calendar entry gets tedious fast. On Xiaomi phones running MIUI, widgets show that information directly on the home screen without unlocking the app first. Many users only find wallpaper and icon-organizing options here, since the widget menu is easy to miss.

Turn On/Off Incognito Mode in Mi Browser

If Mi Browser keeps saving your search history and open tabs even though you wanted a private session, Incognito mode is probably switched off. Once active, the tab icon shows a small mask and the background turns dark purple, but many users never notice the toggle or find it again after closing the app. Without it enabled, every page you visit stays logged in your browsing history.

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.

Allow or Deny Picture-in-Picture Access per App

If a video keeps floating over your screen after you switch away from an app, or a floating window refuses to disappear while you're typing a message, picture-in-picture is active for that app. Some apps use this floating window aggressively even when you just want the screen back to yourself, while others lose the ability to keep playing video in the background because the permission got switched off. This setting controls exactly which apps are allowed to open that overlay window on your Xiaomi phone.

Create a New Event in the Calendar App

If a date only lives in your head, it disappears the moment you get distracted. The Calendar app on your Xiaomi phone lets you save events with a title, guests, location and repeat schedule, but many users only ever use the quick add-note shortcut and miss the full event options. Skipping the dedicated event category also means no reminder fires before the actual date.

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.
