Forget a Saved Wi-Fi Network
If your Oppo phone keeps reconnecting to an old Wi-Fi network with a wrong password or a router you no longer use, it is still sitting in the saved network list. ColorOS holds on to every network you have ever joined until you remove it yourself, which can cause slow reconnects or a jump to the wrong access point when two networks share a similar name.
Disable Mirror Effect for Front Camera Selfies
Selfies taken with the front camera on Oppo phones often come out mirrored, so text and logos appear backwards and your face looks flipped compared to how others actually see you. This happens because the camera saves the photo exactly as shown in the live preview instead of correcting the flip. The Flip Selfie setting controls this behavior, but it sits inside the advanced camera settings and is easy to overlook.
Volume Key Shortcut for Accessibility Features
If you rely on a specific accessibility feature every day, digging through menus each time to turn it on or off gets tedious fast. Oppo phones running Coloros let you trigger that feature directly with the volume keys, but the shortcut only works once it has been linked to a function and switched on. Until then, pressing volume up and down together does nothing.
Allow Unlimited Data for Apps in Data Saver
When Data saving mode is on, your Oppo phone cuts mobile data access for most apps in the background, which often causes missed notifications or apps that only load content over Wi-Fi. You can still whitelist specific apps so they keep full data access even while data saving stays active for everything else.
Raise to Wake Setting
If your Oppo screen keeps lighting up on its own while the phone sits on a table or rides around in your bag, a motion sensor is picking up every small movement. That behavior comes from a gesture setting that wakes the display the moment the phone is lifted or shifted, and it can drain battery or trigger accidental touches when you did not mean to check the phone.
Turn Touch Sounds On or Off
If your Oppo phone plays a short click every time you tap the navigation buttons or on-screen keys, the 'Touch sounds' feature is active. Some people find this feedback helpful, others just want a quiet phone without extra clicks on every tap. The setting sits separately from your ringtone and notification sounds, so muting your phone will not remove it.
Default USB Configuration Settings
Connect your Oppo phone to a PC and a notification pops up every time, asking whether to charge only or transfer files. This behavior comes from a hidden developer option that most people never adjust, so the prompt keeps interrupting the same routine.
Remove a Folder from the Home Screen
Deleting a folder on your Oppo phone can go two ways: either the folder disappears together with every app icon inside it, or only the folder itself is dissolved and the apps land back on the home screen. Mixing up these two options often leads to accidentally losing apps you actually wanted to keep.
Add Another Fingerprint
If your Oppo phone only recognizes one finger, unlocking fails whenever that hand is wet, bandaged or busy holding something. Password & biometrics stores just the first scan by default, so app locks and mobile payments depend on that single print. Adding a second or third fingerprint, even from another person in the household, removes that single point of failure.
Dark or Light Theme for the Phone App
If the Phone app on your Oppo still opens in a bright white interface at night, it can strain your eyes and drain the battery faster than needed. Unlike the rest of ColorOS, the dialer and call screen sometimes keep their own display setting separate from the system-wide dark mode. Switching it manually only takes a few taps.
Turn USB Tethering On or Off
If your laptop or tablet won't get online after you plug in your Oppo phone via USB cable, the internet connection usually is not shared yet. USB tethering has to be switched on manually before the connected device can use your mobile data.
Remove a Widget from the Home Screen
A widget sitting on your home screen refuses to move or just clutters the layout, and tapping it only opens the linked app instead of offering a way out. On some Oppo models the widget also feels stuck in place, as if it were locked to that spot.
Reset Network Settings on Oppo
If your Oppo phone keeps dropping Wi-Fi, refuses to pair Bluetooth devices, or mobile data won't connect properly, a corrupted network profile is often the cause. Resetting the network settings clears these saved configurations and lets Android rebuild them from scratch. It won't touch your photos, apps, or personal data.
Answer an Incoming Call
If a call pops up on your Oppo and tapping the screen does nothing, you are probably looking for the wrong gesture. Oppo phones show incoming calls as a full-screen alert rather than a simple tap-to-answer button, which confuses anyone switching from a different Android brand.
Rename a Paired Bluetooth Device
When your Oppo phone's Bluetooth list fills up with entries like 'Speaker' or 'Headset-XYZ123', picking out the right device becomes a guessing game. ColorOS displays the broadcast name sent by the accessory itself, not a name you chose. Renaming the paired entry lets you tell devices apart at a glance, especially once you have several speakers, earbuds, or car systems saved.
Manage App Permissions
Oppo apps often ask for access to storage, location, or contacts right after installation, and the request rarely explains why the permission is needed. Granting everything by default can let apps read data they never use for their actual function. ColorOS lets you review and change each permission per app at any time, without reinstalling anything.
Hide and Show Apps on the Home Screen
Anyone can open your banking or messaging app just by tapping its icon on the home screen. Coloros lets you hide selected apps behind a password prompt, but the setting sits inside the Privacy menu and is easy to overlook. Once an app is hidden, it disappears from the app drawer and only reappears after you unlock it through a hidden code.
Show or Hide Notification Icons in Status Bar
On Oppo phones, every app pushes its own icon into the status bar, which quickly turns the top of your screen into a cluttered icon row. If you only want to see how many unread notifications you have, or nothing at all, the icon display is controlled through a separate notification setting. This setting changes how icons appear, not whether you actually receive notifications.
Turn Bedtime Mode On or Off
If your phone still lights up with notifications and full color at night, Bedtime mode probably isn't scheduled correctly on your Oppo. This feature only runs inside a fixed time window, so a wrong start or end time keeps Do Not Disturb and grayscale from kicking in. Manual toggles alone won't stick without an active schedule.
Block Offensive Words in Gboard Suggestions
Typing certain words on your Oppo keyboard and getting no suggestion at all can be confusing, especially if autocorrect skips slang or informal terms you actually meant to use. This happens because the Block offensive words option in the keyboard text correction settings filters out profanity and vulgar terms before they reach the suggestion bar. Switching this filter on or off changes exactly what Gboard is allowed to suggest while you type.
Enable Geotagging for Photos and Videos
If your photos never show where they were taken, geotagging is likely turned off in the camera settings. Without it, the shot's location never gets written into the file's metadata, so gallery apps and map views cannot place the picture on a map later. This toggle sits directly in the camera app, separate from the general location settings.
Show Connection Speed in Status Bar
If you keep opening the data usage screen just to check how fast your connection is, Oppo can show that number right next to the signal icon instead. On Coloros this real-time network speed indicator is switched off by default, so the status bar only displays signal strength and battery. Turning it on adds a live Mbps or KB/s reading that updates while you browse or stream.
Flash Alert for Incoming Calls
If you often miss calls because your Oppo phone is face-down or the screen is off, the ringtone alone might not be enough in a noisy room. Coloros can blink the camera flash for every incoming call, but the option sits buried in the calling settings and stays off by default. Turning it on, or switching it off again if it bothers you, only takes a few taps once you know where to look.
Unarchive a Conversation in Messages
If a chat suddenly disappears from the Messages home screen on your Oppo phone, it usually was not deleted but moved to the archive. Archived conversations stay hidden until you pull them back manually, so incoming texts from that contact can go unnoticed. This mostly happens after swiping a chat away or tidying up the inbox.
