Show or Hide Declined Calendar Events
Declined meeting invites disappear from the Xiaomi Calendar app by default, so you cannot see which appointments you turned down or check past responses. This happens because the toggle that controls declined-event visibility is switched off in the calendar settings. Depending on how your Google account syncs, hidden entries can also make your event history look incomplete.
Restore Deleted Contacts from Trash Bin
Accidentally deleted a contact on your Xiaomi phone and now you cannot call or message that person? MIUI keeps removed contacts in a separate Trash folder before they disappear for good, so nothing is lost right away. You just need to find that folder before the 30-day window runs out.
Change Calendar View
If your Google Calendar app on Xiaomi always opens in Month view, finding today's appointments takes extra scrolling. The default layout does not match how you actually plan your day. Switching between Schedule, Day, 3-Day, Week and Month views fixes this without touching any system settings.
Turn On/Off Dial Pad Tones
Every digit you tap on the Xiaomi phone app's dial pad triggers a short beep, and that tone lives in a settings menu that has nothing to do with the calling app itself. In quiet places or shared rooms, that repeated clicking sound gets annoying fast, especially if you dial full numbers manually. Other users want the opposite problem solved: the tone stopped playing and they miss the tactile feedback while typing a number.
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.
