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.
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.
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.
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.
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.
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.
Set a Screen Lock with Pattern, PIN or Password
If your Oppo phone still opens with a simple swipe, anyone who picks it up can read your messages, photos and banking apps without entering a code. ColorOS keeps the pattern, PIN and password options tucked inside a security menu that many people never open, so the phone stays unprotected by default. Without this lock active, features like remote find-and-wipe also lose part of their effectiveness.
Screen Timeout Settings
If your Oppo display locks itself after just a few seconds while you are still reading or filling out a form, the screen timeout is set too short for how you use the phone. Coloros applies a default auto screen off value that favors battery savings over convenience. The duration can be raised or lowered anywhere between a few seconds and half an hour.
Check App Battery Consumption
If your Oppo phone drains faster than usual, background apps are often the reason, but WLAN, Bluetooth and screen brightness also pull a lot of power. Coloros keeps a short usage history so you can see which app or function used the most energy recently.
Auto Turn-Off for Personal Hotspot
If your Oppo phone keeps its Wi-Fi hotspot running long after every device has disconnected, it drains the battery for no reason. ColorOS includes a setting that shuts the hotspot down automatically once nothing has used it for a while. Without that toggle enabled, the hotspot stays active until you switch it off by hand.
Turn On/Off Device Administrators
If you can't uninstall an app on your Oppo phone, it's likely still registered as a device administrator. Apps with this status get deep system permissions like remote lock or full data wipe, which is exactly what blocks the normal uninstall process. Google's Find My Device is the most common app running with this access by default.
Add a Keyboard Language on Gboard
If you type in more than one language, the default Gboard setup only offers your phone's system language and blocks you from typing accented characters or a different script. Switching the whole system language just to write a message is not necessary. Gboard can hold several languages at once and let you switch between them while typing.
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.
Add and Manage Words in the Personal Dictionary
If your Oppo keyboard keeps autocorrecting names, abbreviations, or technical terms you actually want it to remember, the built-in Personal dictionary is likely empty or missing those entries. ColorOS lets you store custom words and optional shortcuts so the keyboard suggests them instead of fighting you. This mainly affects people who type industry jargon, nicknames, or non-standard spellings regularly.
Select Network Manually
When you cross a border or travel abroad, your Oppo phone keeps searching for its home carrier and can end up on weak or costly foreign signal without you noticing. Automatic network selection ranks carriers by signal strength, not by cost or reliability, which causes dropped calls in border regions. Switching to manual selection lets you pick the exact carrier your phone connects to.
