Key Long-Press Delay
If holding down a key on your Xiaomi keyboard inserts a symbol too fast or not at all, the long-press delay is usually the reason. MIUI ships with a fixed 300ms wait before a held key triggers its second character. You can move that value anywhere between 100ms and 700ms to match your typing speed.
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.
Set Up a Proxy Server for Wi-Fi
If your network admin or workplace requires traffic to run through a specific server, a plain Wi-Fi connection on your Xiaomi phone will not route it correctly. Without a configured proxy hostname and port, apps either fail to connect or bypass the required server entirely. This affects browsing, app updates and anything that depends on that network policy.
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.
Turn Bluetooth On or Off
If a Bluetooth headset, speaker, or car kit will not pair with your Xiaomi phone, Bluetooth is often still switched off or was never fully enabled after a restart. The Quick Settings toggle can also drift out of sync with the actual radio state, which leaves paired devices unable to reconnect until you check the setting directly.
Turn On/Off Increasing Ringtone Volume
If every incoming call blasts full ringtone volume right away, or the ringtone feels too quiet at first and only gets loud after several rings, the Increasing ringtone volume option is the setting behind that behavior. It decides whether calls start soft and grow to your set volume level or play at full strength from the first ring. This setting sits separately from the general ringtone volume slider and often gets overlooked when troubleshooting calls that feel too jarring or too quiet.
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.
Turn Data Roaming On or Off
If your Xiaomi phone connects to a foreign network, no data moves until data roaming is switched on. Once active, you get internet access abroad, but your carrier may bill extra for it. Xiaomi does not offer a simple on/off toggle here - it gives you three distinct roaming states, and picking the wrong one either blocks data or leaves roaming running when you do not want it.
Add or Remove Bookmarks in Mi Browser
Losing track of a website you visited last week is common once it drops out of your browser history. Bookmarks fix this by saving the page permanently until you decide to remove it. The catch is that many Xiaomi users don't know where the bookmark list actually lives inside Mi Browser, so saved pages get forgotten or accidentally deleted.
Change the Always-on Display Clock Style
If the Always-on display on your Xiaomi phone only shows a plain digital number and you want something more analog or more detailed, the clock style is buried a few taps deep in the display settings. Many users never notice the option because it sits inside a submenu, not on the main Always-on display toggle screen. Picking the wrong style can also affect how much info fits on the lock screen and how visible the clock stays in daylight.
Change Display Size
If text and icons on your Xiaomi phone look too small or too cramped, the Display size setting is usually the cause. It scales both the interface and the font size together, which can push app shortcuts around on your home screen until you rearrange them.
Turn Off Wi-Fi Hotspot Automatically
Leaving the personal hotspot active after every connected device disconnects quietly drains battery on Xiaomi phones. MIUI includes a setting that shuts the hotspot down on its own once nothing is using it, but most owners never notice it exists.
Turn Off App Lock
If Xiaomi's App lock keeps asking for a PIN, pattern or fingerprint before certain apps open, and some apps seem to have vanished from your app drawer, the lock feature is still active in the background. Turning it off releases every protected app at once and brings previously hidden apps back into view.
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.
Set Notification Sounds for Each App Individually
When every app on your Xiaomi phone plays the same notification tone, it gets hard to tell a messaging alert from a random app update without looking at the screen. MIUI lets you assign or mute sound per app, but the option sits inside a settings area many users never open. Here is where that control actually lives and how to change it for one app at a time.
Turn Glide Typing On or Off
If typing feels slow because you tap every single letter, Glide typing lets you swipe across the keys instead of lifting your finger. On some Xiaomi phones this swipe input stays off by default, or it keeps running even though you prefer classic tapping. Auto-correction and word suggestions are separate settings and keep working either way.
Set a Custom Watermark in the Camera App
If every photo automatically shows your device or camera model as a watermark, you might want your own text there instead. The Watermark settings inside the Camera app let you swap that default label for a personal signature, but the option sits a few taps deep in the menu. Once set, the custom text gets stamped on every new shot instead of the model name.
Wi-Fi Direct Setup
Streaming a video or photo to your TV or Fire TV Stick only works if both devices can see each other on the network, and Wi-Fi Direct connections often fail silently when that handshake breaks. Your Xiaomi phone needs to be on the same wireless network as the receiving device before Wi-Fi Direct can even scan for it. If the target device never shows up in the device list, this direct-connection setting is usually the first thing to check.
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.
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.
Show or Hide Password Characters While Typing
On Xiaomi phones, every character you type into a password field flashes briefly on screen before turning into a dot. If you unlock accounts in public, on a video call, or while someone else can see your display, that brief character preview can expose your password to anyone nearby.
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.
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.
