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.
Show SIM Card Messages
Old text messages from years back sometimes stay on the SIM card instead of moving into the phone's internal storage. If you swap the SIM into a new Xiaomi phone, those messages do not show up in your normal inbox automatically, so it looks like they are gone.
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.
Manually Add an APN
If mobile data drops out or MMS messages will not send on your Xiaomi phone, the access point name (APN) supplied by your carrier might be missing or wrong. This entry is normally created the first time you insert a SIM card, but a factory reset, a new SIM, or a carrier update can wipe it out. Without a correct APN, the phone shows full signal but cannot actually load data.
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.
Schedule Power On/Off
If you keep forgetting to switch your Xiaomi phone off at night or want it ready and running before you even reach for it in the morning, pressing the power button every time gets old fast. MIUI includes a built-in scheduler that turns the device on and off at fixed times you define, with support for daily repetition or custom days. Once set up, the phone handles the switching on its own, without any manual input.
Set Data Usage Warning Level
If you have already capped your monthly data plan on a Xiaomi phone, you might still get surprised when the limit hits without any heads-up. The warning level tells MIUI at what percentage of your data plan it should alert you before you run out.
Set a New Alarm
Waking up on time with a Xiaomi phone means finding the right spot to add a repeating schedule, a custom label, or a different ringtone for each alarm. Many users only set a one-off alarm and miss the options for weekday repetition, vibration, or automatic deletion after the alarm rings. Getting these details wrong means the alarm either fires on the wrong days or disappears after a single use when you actually wanted it daily.
Turn On or Off Reading Mode
If your Xiaomi phone throws a cold, blue-tinted glow at night, reading on it can feel harsh and even keep you awake longer. Reading mode warms up the display colors to ease eye strain, but a lot of people never find the toggle or the scheduling option. Without it set up correctly, the warmer tone never kicks in on its own when you need it.
Set Default Reminder Time for Calendar Events
Every new event in the Calendar app on a Xiaomi phone gets the same reminder time by default, even when it does not fit the appointment. Resetting the reminder manually for each entry gets tedious fast, especially for recurring meetings. This default value comes from a setting most people never open.
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.
Change Keyboard Layout in MIUI
If your Xiaomi keyboard still types QWERTY while you actually need QWERTZ, AZERTY or another layout, every second word ends up misspelled. MIUI lets you switch or add layouts per language, including Dvorak, Colemak, Neo2 and a plain PC layout, but the setting is buried several menus deep inside the keyboard options. Handwriting input is listed there too, in case none of the fixed layouts match how you type.
Allow or Deny Do Not Disturb Access for Apps
When an app suddenly enables Do Not Disturb on its own, or a call app keeps muting notifications you actually want to see, a hidden system permission is usually behind it. On Xiaomi phones, individual apps can request permission to switch Do Not Disturb on or off, and that access is not always obvious from the app itself. Checking which apps hold this permission helps you regain control over your notifications.
Search Bar in Notification Shade
Pulling down the notification shade on a Xiaomi phone sometimes shows an extra search field at the top that you never asked for, or the opposite happens and you want that shortcut back. This toggle sits in Mi Browser, not in the notification settings where most people go looking for it. Without knowing that, the option seems to be missing entirely.
Archive a Conversation in Messages
When your chat overview gets cluttered with conversations you want to keep but do not check daily, the Messages list keeps showing all of them at the top. Archiving hides a conversation without deleting it, and you can bring it back anytime.
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 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.
Focus & Shoot: Turn On or Off
If tapping the screen on your Xiaomi camera fires the shutter right away instead of just setting focus, Focus & shoot is switched on. Some people rely on this two-tap workflow to keep the phone steady, while others get accidental photos while they are still framing the shot.
Change Notification Sound
When every app on your Xiaomi phone plays the same generic chime, spotting an important message in a stack of notifications gets tricky. MIUI lets you pick a different tone per notification type, and if you run two SIM cards you can even split the sound by line. The tricky part is finding where this setting actually lives, since it is buried a few taps below the general Sound menu.
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.
Turn Best Photo Marks On or Off
If your Gallery keeps flagging one photo out of a burst as the best shot, MIUI is comparing similar images and tagging the sharpest or best-exposed one automatically. Some users find this helpful for sorting large photo batches, others just want a clean gallery without extra labels. The setting controls whether this comparison runs at all.
Turn Autofill Service On or Off
If login fields on your Xiaomi phone stay empty or a browser keeps offering saved passwords you never asked for, the Autofill service is likely misconfigured. This system feature decides whether apps and browsers can pull addresses, payment details or passwords into forms automatically. Switching providers or turning the service off changes what gets filled in and which app holds that data.
Set Pop-up Window Action Timeout
If a pop-up window or temporary app alert disappears before you can tap a button, or lingers on screen far longer than needed, the accessibility timeout is set too short or too long for how you use your phone. This value decides how much reaction time you get on prompts that show up briefly and then close on their own. MIUI lets you adjust this timing instead of leaving it on the default.
