Turn Off Screen Lock
If entering a PIN or pattern every time you check your phone feels unnecessary, you can remove the lock screen password on your Oppo phone entirely. The option sits under Password & biometrics and needs your current unlock code to confirm the change. Once disabled, the screen no longer asks for a code and unlocks with a simple swipe.
Share Single or Multiple Contacts
Sending someone a contact from your Oppo phone often means retyping a phone number by hand because the built-in Contacts app hides the sharing option behind a long-press gesture. Both single entries and whole groups of contacts can be exported as a vCard or text file, but many users never find the menu that triggers it.
Change SIM Card Name
On Oppo phones with dual SIM, both cards show up as SIM1 and SIM2 in call logs, texts, and network settings. That makes it tricky to tell a work line apart from a personal number at a glance. You can swap in a custom label for each SIM instead, up to ten characters long.
Turn an Alarm On or Off
If an alarm keeps ringing even though you thought you disabled it, or it stays silent when you actually need it, the toggle next to that alarm entry is probably in the wrong position. On Oppo phones every alarm has its own on/off switch, so one alarm can stay active while others are paused. This mix-up is common when you have several alarms set for different days or routines.
Change Preferred Network Type
If your Oppo phone keeps dropping back to a slower connection or refuses to lock onto 5G, the Preferred network type setting is usually the reason. This option tells the modem which network generation to search for first, and a wrong choice leads to dropped calls, sluggish data, or a missing 5G icon. The available options depend on your device model and what your carrier actually supports.
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.
Change System Language on Oppo
If your Oppo phone boots up in the wrong language after a reset or a SIM swap, menus, keyboard suggestions and app names stay unfamiliar until you fix the system setting. ColorOS is a modified version of Android, so every language available on a standard Android phone is also present here, just filed under a different menu than on other brands. Many people search the main Settings screen and never find the option, because it sits inside a secondary settings group.
Clone Apps with App Cloner
Need two WhatsApp, Facebook or Messenger accounts on one Oppo phone but the app only allows a single login? ColorOS lets you install a second, independent copy of many apps so you are not stuck switching accounts all day. This is especially useful on dual-SIM devices where each SIM needs its own messaging identity.
Power Button Ends Call Setting
Reaching for the screen to hang up takes an extra step when you are already holding the phone to end a call quickly. On some Oppo phones the power button does nothing during an active call, even though Android supports using it to hang up instantly. This setting sits inside the calling accounts menu and is off by default on many devices, so calls only end via the on-screen button unless you switch it on yourself.
Add Widgets to the Home Screen
If your Oppo home screen only shows app icons and folders, you are missing widgets that display live info like weather, calendar events, or battery status. Many users never spot the widget menu because it does not sit in the regular app drawer. Both system apps and many installed apps offer their own widgets in different sizes.
Name Format for Call History
If some contacts show up as Lastname Firstname while others read the opposite way in your call history, Oppo is applying a name format that does not match how you saved the contact. This setting controls whether the call log displays first name or last name first, and it can behave differently from the order used in your contacts app. Mixed formats usually come from contacts imported from different sources or accounts.
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.
Turn Auto-correction On or Off
If words get swapped or rewritten while you type, without any underline or tap-to-confirm option, auto-correction is silently editing your text. This sits inside the keyboard settings, not in any messaging app itself. Typing names, slang, or technical terms becomes annoying when the keyboard keeps replacing them on its own.
Enable Face Recognition for App Lock and Private Safe
If Oppo face unlock only works for the lock screen, you might not know it can also protect individual apps and the Private Safe. Many users set up Face once for unlocking the phone and never realize App Lock and Private Safe use a separate toggle in the same menu. Without turning that option on, those areas fall back to a password or pattern even though your face profile already exists.
Turn On/Off Game Space
If calls still ring through during a match or notification banners keep popping up over your game, Game Space is probably switched off or one of its assistant options got disabled. This toggle controls whether Oppo's game launcher actively manages calls, alerts and performance while you play. Getting it wrong either way means either constant interruptions or a launcher that keeps popping up when you do not need it.
Customize Displayed Contacts by Account
If your Oppo phone is signed into several accounts, the Contacts app can turn into a long, mixed list of numbers you never call. Every synced account adds its contacts by default, so work emails, old SIM imports, or a rarely used Google account can bury the people you actually text. Coloros lets you pick exactly which sources show up in that list.
Adjust Audio Balance
If one ear picks up music, calls or video sound louder than the other, the audio balance on your Oppo phone is skewed toward the left or right channel. This often goes unnoticed until you use earbuds or a headset and one side feels noticeably quieter. A hidden slider in the accessibility settings controls this balance and can be nudged back to center.
Set Network Permissions per App
Some apps on your Oppo phone keep using mobile data even when you only want them online over WLAN, or the other way around. This happens because every app defaults to both mobile data and WLAN access unless you change it manually. Without a fix, background data usage climbs and apps may try to connect even when no WLAN network is nearby.
Change Screen Lock PIN, Password or Pattern
Switching from a pattern to a PIN or picking a fresh password on an Oppo phone does not mean wiping the lock screen and starting over. Coloros keeps your fingerprint and face data untouched while you swap the unlock method, but the actual option to change it sits one level below the main lock screen menu. Many users only find the reset entry and assume they have to set up biometrics again.
Accessibility Menu: Enable or Disable
If you don't see a small round shortcut icon in your navigation bar, the Accessibility Menu on your Oppo phone is switched off. This menu gives quick access to frequently used apps and system functions without digging through several screens. It's especially useful for older users or anyone who wants fewer taps to reach common actions.
Auto Click After Pointer Stop On/Off
Connect an external mouse to your Oppo phone and a click sound triggers itself whenever you stop moving the cursor for a moment. This comes from the accessibility feature Click when pointer stops, which fires a click automatically once the pointer rests, even if you did not press any button.
Change Notification Sound
If every app on your Oppo phone plays the same generic tone for new messages, emails, and app alerts, it gets hard to tell them apart without checking the screen. Coloros uses one shared default notification sound for most apps, while the Phone and Messages apps keep their own separate tone settings. Swapping this default tone is done once in the sound settings instead of inside each app.
Turn On or Off Large Mouse Pointer
When you plug an external mouse into your Oppo phone, the default pointer often gets lost on busy wallpapers or in split-screen mode. This makes precise taps and drags harder, especially on bigger displays or when the phone is mirrored to a monitor. A visibility setting inside Accessibility controls exactly this, but most people never find it.
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.
