Delete Face Unlock Data
If you no longer want face recognition to unlock your Oppo phone, the stored face scan needs to be removed manually from the security settings. This step requires your screen lock password or PIN, and skipping it means the phone keeps trying to match your face every time the display wakes up. Some users also notice slower unlock attempts or repeated fallback to PIN entry when an outdated face profile is still active.
Show or Hide the Fingerprint Icon on the Lock Screen
On Oppo phones with an in-display fingerprint sensor, a small icon lights up at the sensor spot even while the screen is off. Some people find this glowing marker distracting at night or suspect it drains battery, and want to turn it off without losing fingerprint unlock. The toggle for this sits inside the screen-off unlock options, separate from the unlock function itself.
Remove a Saved Fingerprint
An old or unauthorized fingerprint on your Oppo phone is a security gap, especially if it belongs to someone else or was only added for a quick test. That print stays active in the background and can unlock the device or confirm payments without you noticing. Clearing it out is the only way to be sure who can actually get in.
Turn On/Off Focus Mode
When Focus mode is active on your Oppo phone, the apps you marked as distracting stop running in the background, so no messages or alerts come through until you check them manually. That silence can look like a bug, especially if you enabled the feature by accident or forgot a schedule was running. Coloros keeps the block in place until you switch the mode off or the scheduled window ends.
Schedule Do Not Disturb
Turning Do Not Disturb on and off by hand every night gets old fast, especially if your sleep or work hours shift. On Oppo phones, a missed toggle means notifications either interrupt you too early or stay silent longer than planned. A saved schedule handles the on and off switch on its own, without you touching the setting again.
Double-Space Period Shortcut
Typing two spaces after a word sometimes inserts a period automatically, even when you only wanted extra spacing. This happens because the Gboard text correction feature turns a double space into a full stop at the end of a sentence. If the shortcut is missing or keeps triggering unwanted periods, the option needs to be checked directly in the keyboard settings.
Turn Screenshot Sound On or Off
Every screenshot on your Oppo phone plays a camera-shutter sound, even in meetings or quiet rooms. That noise comes from a dedicated toggle in the sound settings, not from the screenshot gesture itself, so silent mode alone often does not stop it.
Turn HDR On or Off in the Camera App
Photos taken indoors or against bright windows often come out either too dark in the shadows or completely blown out in the sky. That happens because the HDR mode in the Camera app is set the wrong way for the scene you are shooting. Switching it on or off manually gives you more control over exposure than letting the camera decide on its own.
App Animation Speed
If apps on your Oppo phone take a moment too long to open or the closing animation feels sluggish, the app animation speed is probably set slower than you like. This Coloros setting controls how quickly the transition plays when you launch or close an app, separate from actual app loading time.
Change Start of Week in Calendar
If your Oppo calendar always opens on the wrong weekday, the region-based Start of the week setting is usually the cause. This throws off the weekly grid in the Calendar app, which gets confusing if you are used to a different day as the first one. You can pick Saturday, Sunday or Monday to match your own routine.
Add Apps and Games to Game Space
If a game or app does not launch inside Game Space on your Oppo phone, it usually has not been added to the managed list yet. Without that step, the app starts as a normal application and misses out on performance tweaks, do-not-disturb, and other Game Space functions.
Export Contacts to a vCard File
On Oppo phones running ColorOS, the built-in export tool only saves contacts to local phone storage, not directly to a cloud service or another device. The result is a single .vcf file containing every contact detail, and you get to pick which account's contacts go into it. If you expected a direct transfer option, this local-only behavior can be confusing.
Allow Calls During Do Not Disturb
If Do Not Disturb is active on your Oppo phone, calls get silenced unless you add an exception. You can choose to let calls through from everyone, only from saved contacts, or from a handful of selected people. Missing this setting means important calls go straight to silence with no ring at all.
Custom Notification Sounds per App
If every app on your Oppo phone plays the same generic notification tone, it gets hard to tell a chat message apart from a calendar reminder just by sound. Coloros lets you assign a separate ringtone to each app, but the option sits inside app management instead of the general sound settings. Many users only ever find the global tone switch and assume individual app sounds are not possible.
Turn Split Screen On or Off
If a three-finger swipe up does nothing on your Oppo phone, split screen mode might be switched off in the background. ColorOS ships with the feature active out of the box, but the gesture only works while split screen itself stays enabled in the settings.
Set Date Manually
If the date on your Oppo phone is wrong and there is no direct way to edit it, the automatic time sync is the reason. ColorOS locks date and time together, so both need attention once automatic sync gets switched off. Skipping the time step often leaves the clock inaccurate even after you set the correct date.
Turn On/Off Magnification (Accessibility)
If text and icons on your Oppo phone are too small to read comfortably, the built-in magnification tool works like a digital magnifying glass. A triple tap on the screen opens a zoom window that you control with a two-finger pinch. The feature covers the entire display except the keyboard and navigation bar, and many users cannot find where to switch it on or off.
Unlock Private Safe with Fingerprint
Typing in your privacy password every time you want to check files in Private Safe gets tedious fast. Oppo phones let you swap that PIN, pattern or password entry for a fingerprint tap, but the toggle sits buried inside biometric settings and stays off by default. Without switching it on, the fingerprint sensor you already use to unlock your phone has no effect on the vault.
Uninstall an App via Settings
Long-pressing an app icon on your Oppo home screen and tapping Uninstall does not always work, especially if the shortcut sits inside a folder or has been removed from the home screen entirely. In that case the quick gesture method fails and you need a menu that lists every installed app regardless of where its icon lives. The App management section in Settings covers exactly that gap.
Remove an App Shortcut from the Home Screen
If a shortcut icon refuses to disappear when you try to clean up your Oppo home screen, the App Drawer setting is usually the reason. With App Drawer enabled, removing a shortcut only deletes the icon, not the app. Without it, home screen icons and installed apps are the same thing, so removing one uninstalls the other.
Show or Hide the Emoji Switch Key on Gboard
On Oppo phones with Gboard, an emoji icon sits next to the space bar by default, letting you jump straight into emojis while typing. If you rarely use it, or you actually need that spot for the language switch button instead, the emoji key gets in the way. Both buttons cannot be shown at the same time, so one always replaces the other.
Create an Event in Calendar
The Calendar app on Oppo smartphones lets you create events, but also goals, reminders, and tasks from the same menu. Each entry type asks for different fields, so picking the wrong one can mean missing a location box, a due date, or a reminder toggle later.
Delete Photos or Videos
Storage fills up fast when old photos and videos pile up in the Oppo Gallery app, and deleting them one by one feels endless. Switching to edit mode lets you select several files at once, but the items you remove do not disappear right away. They sit in the Trash for a while first, which still counts against your free storage until they are cleared out.
Send a Photo via Bluetooth
A photo from the camera or Gallery does not reach a paired device automatically, and the Bluetooth send option is easy to miss inside the sharing menu. Bluetooth transfer only works once a device is paired and switched on, but the actual command sits in the Send sheet, not in the Bluetooth settings screen. The same process applies to PDFs, videos, contacts and other file types, not just photos.
