Change Camera Photo Frame Ratio
Photos taken in the default 4:3 frame show black bars when you stream them to an HDTV or play them back on a widescreen display. Switching to a 16:9 ratio matches modern screens and avoids the letterboxing, while a 1:1 crop works better for square social posts. The frame setting sits in the camera menu and is easy to miss if you never open it.
Change Camera Picture Quality
If your camera storage fills up fast or photos take too long to share, the picture quality setting in the MIUI camera app is often the reason. Xiaomi's camera defaults to a high resolution that produces large files, even when you only need a quick snapshot. Switching between High, Standard, and Low lets you balance sharpness against file size for each situation.
Turn Notification Badges On or Off Per App
A red dot keeps sitting above an app icon even after you have opened every message inside it. On Xiaomi phones this badge is a separate switch from the notification itself, so muting an app does not always remove the counter. If the dot never clears, or shows up for an app you barely use, the badge toggle for that specific app is still turned on.
Turn an Alarm On or Off
Alarms you already set on your Xiaomi phone stay stored even after you switch them off, but the toggle in the Clock app is easy to miss. If an alarm keeps ringing when you do not need it, or stays silent when you want it active, the switch next to the entry is probably in the wrong position. This affects your wake-up routine and any reminders you set up in MIUI.
Manage the Personal Dictionary
If your keyboard keeps autocorrecting a name, brand term, or slang word you actually want to type, MIUI's personal dictionary is the setting that controls this behavior. Without an entry there, the keyboard falls back to its built-in wordlist and ignores your preferred spelling or shortcut for longer phrases.
Add Update Shortcut to Home Screen
Checking for a new MIUI version usually means digging through several settings screens on a Xiaomi phone. A home screen shortcut skips that detour and opens the update check directly. Without it, casual users often forget to check for updates at all.
Remove App from Folder
When a folder on your Xiaomi home screen fills up with apps you barely touch, finding the one you actually use often becomes annoying. This happens a lot with apps like Messenger or WhatsApp, which start in a folder but end up needing a spot of their own once you rely on them daily. MIUI lets you pull an app back out without deleting anything.
Sound and Vibration for Calendar Reminders
If birthday or appointment reminders in the Calendar app stay silent, or if they buzz and ring when you would rather have them quiet, the notification settings for that app are usually the cause. On Xiaomi phones this is controlled separately from the general system sound, so a muted phone does not automatically mean the calendar stays quiet too. Checking the dedicated Calendar notification options clears up most missed or unwanted reminder alerts.
Battery Optimization Settings for Individual Apps
If a messaging app stops delivering notifications until you open it, or a background app quietly drains your battery overnight, MIUI's per-app battery optimization is usually behind it. Some apps get frozen too aggressively, others are left completely unrestricted and keep running in the background. Getting this balance wrong either kills battery life or breaks apps that need to stay active.
Change Downloads Location in Mi Browser
If every file you download through Mi Browser lands in the same generic folder, sorting photos, documents and APKs afterward gets tedious fast. The browser has its own storage setting that decides where new downloads go, separate from the system-wide file manager. Once you know where that option sits, you can point downloads straight to the right folder.
Rename a Home Screen Folder
A newly created folder on your Xiaomi home screen often just carries a generic label like 'Folder' or picks up the name of the first app you dropped into it. That makes it hard to tell at a glance whether it holds your shopping apps, finance tools, or games. Once you have several folders sitting next to each other, a clear name is the only thing that keeps your screen readable.
Add a Keyboard Language
Typing in a second language on your Xiaomi phone turns into a mess of red underlines and wrong autocorrect suggestions when the keyboard only knows one language. Messages, emails, and notes in that language become slower to write because every word gets flagged or swapped for something else. The built-in keyboard supports multiple languages at once, but only if you add them manually first.
Set Battery Saver for Individual Apps
If one app drains your battery fast while another stops sending notifications on time, a single phone-wide power saving mode will not fix both problems. Xiaomi lets you assign a separate battery plan to each app instead of forcing every app into the same restriction level. Picking the wrong option for an app can either waste battery or delay important alerts.
Change Device Name
If your Xiaomi phone still shows up under its model number when you scan for Bluetooth devices or connect to a hotspot, that is the default device name at work. It makes picking your phone out of a list of nearby devices harder, especially if you own more than one Xiaomi device. MIUI lets you replace that generic label with a name you actually recognize.
Reset Wi-Fi, Mobile Data & Bluetooth
If Wi-Fi keeps dropping, mobile data stops working after a SIM swap, or paired Bluetooth devices refuse to reconnect, corrupted network profiles are often the real cause. Switching a connection off and on rarely fixes these deeper configuration conflicts. A full network reset clears every saved Wi-Fi password, paired device, and mobile data setting in one pass.
Assign a Photo to a Contact
When a contact shows only initials or a plain avatar during calls and messages, no photo has been linked to that contact yet. MIUI lets you attach an existing picture from your gallery instead of only allowing a new snapshot. Without that link, incoming calls and chat threads stay visually anonymous even if the contact already has a name and number saved.
Turn VoLTE On or Off
If your Xiaomi phone keeps dropping calls to a shaky 2G or 3G signal even though you have full LTE bars, VoLTE is probably switched off. Without it, voice calls ignore your 4G connection and fall back to older, slower networks, which means longer connect times, choppier audio and extra battery use. Turning Use VoLTE on or off is a single switch inside your SIM settings.
Turn Floating Notifications On or Off
Every pop-up banner that slides over your Xiaomi lock screen or current app comes from the floating notifications feature, and not every app should get that permission. If a messaging app keeps interrupting your screen with banners while a quieter app never shows up at all, the per-app floating notification setting is usually the reason.
Turn On or Off Find My Device
If your Xiaomi phone goes missing and Google's Find My Device search comes up empty, the tracking toggle is probably switched off in your privacy settings. This setting decides whether your phone keeps reporting its last known location to your Google Account. Without it enabled beforehand, there is no location history to fall back on once the phone is actually lost.
Show or Hide the Emoji Switch Key
If you type a lot of emojis, switching between the language globe and the emoji picker can slow you down on the MIUI keyboard. The globe icon and the emoji key share the same spot, so only one of them shows on the keyboard row at a time. Turning on the emoji switch key swaps that icon while quick language switching still works by holding the space bar.
Set Up Switch Access
If tapping the touchscreen is difficult or impossible, everyday tasks like opening apps, scrolling, or typing on a Xiaomi phone can become a real barrier. Switch Access lets people with motor disabilities control the phone through one or more external switches instead of direct touch. These switches connect over USB or pair via Bluetooth and take over selection, scrolling, and text entry.
Keyboard Vibration Settings
If every tap on the on-screen keyboard triggers a buzz that feels too strong or too weak, or typing feedback vanished after an update, the keyboard's Haptic feedback on keypress setting is usually the cause. This option runs independently from your general system vibration, so toggling System vibration alone will not fix it. Notifications and Focus mode profiles do not touch this setting either, since it lives inside the keyboard app itself.
Add a Time Stamp to Photos
Photos taken with your Xiaomi phone often show no date or time, making it hard to prove exactly when a picture was captured. This is controlled by the Watermark option inside the Camera app, which stays off by default on most MIUI devices. Without it enabled, every shot leaves the gallery without any timestamp overlay.
Force Stop an Unresponsive App
When an app keeps running in the background and refuses to close normally, closing the recent apps card often does nothing. Force stopping shuts the process down completely, but it can also interrupt saved data or active downloads.
