Double-Space Period Shortcut
If you double-tap the space bar on a Xiaomi keyboard and suddenly get a period you did not mean to type, this shortcut is turned on. If you rely on it to speed up typing and it stops working after a keyboard update, the setting got switched off or reset.
Switch Between Old and New Control Center Style
If your Xiaomi phone still shows the older two-panel layout after an update, or you miss that classic view after switching to the newer simplified overview, the display style does not change on its own. It sits behind a separate setting that many people never open. Notifications and quick toggles stay mixed together until you pick the layout you actually want.
Turn Personalized Ad Recommendations On or Off
If ads on your Xiaomi phone feel oddly tied to your recent searches or app activity, Personalized ad recommendations is the setting behind it. Switching it off does not lower how many banners you see, it only stops MIUI from matching them to your interests and usage data.
Turn Quick Responses On or Off
When a call comes in and you cannot pick up, MIUI can send the caller a short text instead of just cutting them off. If that automatic reply keeps firing at the wrong moments or refuses to trigger at all, the Quick responses feature needs a check.
Turn On Second Space
If you want to keep work apps, private photos, or a guest profile completely separate from your main Xiaomi setup, mixing everything into one home screen becomes a mess fast. Second space creates an isolated area with its own apps, files, and accounts, so nothing from one side leaks into the other. It is different from a simple app lock, because the whole environment is duplicated rather than just hidden.
Set Autoclick Dwell Timing for a Mouse
If you control your Xiaomi phone with a connected mouse, clicking a tiny cursor button gets tiring fast. Autoclick (dwell timing) lets the phone register a click automatically once the pointer stops moving for a set time. The delay is adjustable, so a short dwell time can trigger accidental taps while a long one feels sluggish.
Turn Off Automatic Diagnostic Data Sending
If Send diagnostic data automatically stays enabled, your Xiaomi phone keeps transmitting usage statistics that can include personal details. Many people only notice this after checking a privacy report or reviewing background data usage. MIUI never discloses exactly what content gets sent in these reports, which is why disabling related user experience options is worth doing.
Delete a Conversation
Deleting a text thread one message at a time on a Xiaomi phone takes forever once a conversation has piled up over months. Long threads eat into storage and clutter your inbox, and most people never notice the shortcut MIUI offers for removing a whole conversation at once. Once you confirm the deletion, the messages are gone for good, so it helps to know exactly where to tap first.
Find a Word on a Webpage
Scrolling through a long article on your phone just to spot one specific term wastes time, especially when the page has no search box of its own. Mi Browser hides a page search tool that jumps straight to every match of a keyword. Without it, you are stuck pinching, zooming and reading line by line to find what you need.
Delete Second Space
If the second space on your Xiaomi phone still takes up storage or keeps showing up as a swipe option on your lock screen, removing it completely clears out that whole separate profile. Second space works like a second phone with its own apps, photos and accounts, so it does not disappear just because you stop using it. This guide covers removing it directly from the space settings, which works slightly differently than deleting it through device admin.
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.
Camera Watermarks
The camera watermark stamps a small label into the lower-left corner of your photos, either a standard device signature or a text you choose yourself. It helps you mark ownership, keep track of the device a shot came from, or add a personal touch for photos you share or sell online. Turning it on or off changes future shots only, not photos already stored in your gallery.
Share a Webpage from Mi Browser
Copying a website address by hand often cuts off part of the link or drops tracking parameters that break the page. Mi Browser can send the page straight to WhatsApp, Gmail or Messages, but the share option sits inside the profile menu instead of the main toolbar. Many people end up scrolling through icons before finding the right one.
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.
