Turn On/Off USB Debugging
If MyPhoneExplorer refuses to sync contacts or a rooting tool cannot detect your Xiaomi phone over cable, USB debugging is usually still switched off. The option only appears once Developer options are unlocked, and many users cannot find the toggle afterward. Leaving it enabled permanently also carries a small security risk you should know about.
Restrict Floating Notifications in Do Not Disturb
If your Xiaomi phone keeps popping up banners while Do Not Disturb is active, incoming alerts are still showing as floating notifications instead of staying silent. The messages themselves are not lost, they simply arrive quietly in the background, but the pop-ups still interrupt whatever you are doing. This setting decides whether MIUI shows those floating banners while DND is on.
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.
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.
Set Up Fixed Dialing Numbers (FDN)
If your Xiaomi phone suddenly refuses to dial certain numbers, Fixed Dialing Numbers might be limiting outgoing calls and texts to a preset list. This SIM-level restriction blocks any number that is not on the approved list, even a local number with the right area code. Turning the feature on or off always requires PIN 2, not the regular SIM PIN, which trips up most people who try it for the first time.
