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.
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.
Reset Advertising ID
Ads on your Oppo phone keep matching your recent searches and app habits a little too closely. That happens because every device carries a fixed Advertising ID that links your behavior across apps for personalized ads. Turning off interest-based ads alone does not remove that link - the ID itself needs a reset.
Turn Screenshot Gestures On or Off
If a screenshot pops up every time you swipe down with three fingers, or a partial capture opens whenever you touch and hold with three fingers, the screenshot gesture settings on your Oppo phone are active. These gestures work independently from the button combination and are enabled by default in ColorOS. Random captures while gaming or scrolling usually point to one of these gestures firing by accident.
Hide Photos and Videos in the Gallery
If a photo or video keeps showing up in your gallery even though you want it out of sight, ColorOS does not let you hide entire albums. Instead, single photos and videos get marked as private and disappear from normal browsing. Getting them back means digging into a separate area that is protected by your lock screen password, fingerprint, or face recognition.
Set Up Fingerprint Unlock
If your Oppo phone still asks for PIN, pattern or password every time you wake the screen, the fingerprint sensor probably is not set up yet. Fingerprint unlock only works once a backup method like PIN or pattern is already active, since ColorOS needs that fallback to register your print. The same fingerprint also works as a shortcut to reset a forgotten lock screen password.
Change Lock Screen Wallpaper
If your lock screen keeps showing the same picture as your home screen, ColorOS is applying wallpaper changes to both screens by default. This happens with your own photos, standard wallpapers, and live wallpapers alike. You need to pick the target screen manually to keep the two separate.
Change Security Question for Privacy Password
If you cannot remember the answer to your privacy password security question, you lose the only way to reset a forgotten privacy password on your Oppo phone. ColorOS ties the entire recovery process to that single question and answer, so a weak or forgotten one leaves protected apps and files out of reach. Swapping in a question you will actually remember closes that gap before it becomes a problem.
Add App Exceptions to Do Not Disturb
If Do Not Disturb mode silences a messaging or work app you actually need to hear from, that is expected behavior on Oppo phones, not a bug. Coloros mutes every app by default once Do Not Disturb turns on, and only apps added to the allowed list keep making sound and showing alerts. Without that exception, calls, chats and reminders from that app stay silent until you turn the mode off.
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.
Add Trusted Places to Smart Lock
If your Oppo phone keeps asking for a PIN or pattern even at home or in the office, Smart Lock's Trusted Places feature is probably not configured yet. Without a saved location, the phone falls back to your regular screen lock everywhere, including places you visit every day. Trusted Places keeps the device unlocked within roughly 50 meters of a spot you pick, as long as location services stay on.
Set an Alarm with Custom Repeat and Ringtone
On Oppo phones several alarms exist side by side, each with its own repeat pattern, snooze length, vibration and ringtone. When you set up a new alarm or edit an existing one, it is easy to miss where these individual options actually live and end up with the wrong sound or repeat days. This mixes up daily wake-up alarms with one-off reminders.
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.
Volume Buttons Function for Camera
On Oppo phones, pressing a volume button while the Camera app is open takes a photo instead of adjusting the sound level. This happens because Coloros assigns the buttons to shutter control by default, and the same option can be switched to zoom instead.
Change Font Size
If text on your Oppo phone looks too small to read comfortably or too cramped when enlarged, ColorOS lets you adjust the font size on its own. Only the letters scale up or down, while icons, buttons and layout keep their original size, which can make some screens look unbalanced at the extreme settings.
Turn Personalized Ads On or Off
Every Oppo phone carries a unique Advertising ID that networks use to build a profile from your app usage and browsing habits. If ads keep following you across unrelated apps with oddly specific products, that identifier is the reason. You can either reset this ID for a fresh start or opt out of ad personalization completely.
Adjust Touch & Hold Delay
If long-pressing icons or text on your Oppo feels either too twitchy or too sluggish, the touch-and-hold timing is likely set wrong for your habits. This delay controls how long you need to press before the system registers a touch and hold instead of a normal tap.
Turn Call Vibration On or Off
Every incoming call makes your Oppo phone buzz, even when you already picked a ringtone you like. If that vibration feels distracting, unnecessary at your desk, or drains the battery faster during calls, the toggle for it lives inside your sound settings, not in a separate ringtone menu.
Import Contacts from a vCard File
Switching to an Oppo phone often means your old contacts sit in a vCard file or on another device, and there is no simple sync button for that. Coloros only lets you import a full .vcf file or pull contacts directly from another phone via Bluetooth, without any option to pick single entries from the list. If you only need a handful of numbers, you end up with everything from the source file instead.
Clear App Cache
If an Oppo app keeps loading outdated images, freezes, or your storage fills up faster than expected, a bloated app cache is often the reason. ColorOS stores temporary files like thumbnails and login data so apps open faster, but old or corrupted cache entries can trigger glitches or slow performance. Clearing the cache removes this leftover data without deleting your photos, documents, or app settings.
Add a Contact Photo
If your contact list on Oppo still shows plain initials instead of faces, calls and messages are harder to scan at a glance. This happens because no image has been linked to that contact yet in the Contacts app. Adding a photo works with an existing gallery picture or a new snapshot from the camera.
Forward a Message on Oppo
Retyping a text just to send it to someone else wastes time, especially when the message contains links or details you cannot easily reproduce. Oppo phones let you forward an SMS straight from the conversation, and you can also send it to a different app instead of another contact.
Turn On/Off Select to Speak
When Select to Speak is active, an extra accessibility icon shows up in the navigation bar, and tapping it lets you highlight any text on screen to have it read aloud. It works similar to TalkBack but does not take over your phone's regular touch controls. If that icon suddenly appears or disappears without you doing anything, the setting may have been toggled by accident during a system update or a shared accessibility shortcut.
Edit Quick Decline Messages
When you reject an incoming call with a quick text, Oppo phones send one of four preset replies like 'Sorry, I can't answer the phone now.' These default lines rarely match how you'd actually respond to family, friends, or coworkers. Coloros lets you rewrite all four texts, but the setting sits inside the phone app rather than Messages.
