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.
Turn Smart Sidebar On or Off
If swiping in from the right edge of the screen does nothing, the Smart Sidebar on your Oppo phone might be switched off. The Smart Sidebar normally holds app shortcuts, quick tools like screenshot capture, and quick apps for fast access. When it stays hidden or pops up by accident during games or reading, the toggle for it usually needs adjusting in the system settings.
Turn Eye Comfort On or Off
If the screen feels harsh on your eyes after dark, Oppo's Eye comfort mode is probably switched off or set to the wrong schedule. This blue light filter warms up the display and lets you adjust how strong that tint should be. Many people never notice it because it sits inside Display settings instead of a dedicated night mode switch.
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 a Default Calling SIM for a Contact
On a Dual SIM Oppo phone, outgoing calls tend to go out on whichever SIM was used last, which gets annoying when you keep switching SIM manually before dialing a specific person. If a contact has both a private and a business number saved, the wrong SIM can also mean the wrong caller ID or tariff for that call.
Unpair a Bluetooth Device
A speaker or headset you stopped using still shows up as a paired device on your Oppo phone, and it keeps trying to reconnect whenever it is nearby. Turning Bluetooth off only pauses that link temporarily, it does not remove it. To stop the automatic reconnect for good, the pairing itself has to be deleted.
Optimize Battery Usage for Background Apps
If WhatsApp or Messages notifications arrive late or not at all on your Oppo phone, background battery optimization is usually the cause. ColorOS restricts or shuts down inactive apps to save power, which interrupts push notifications and syncing. You can control this behavior per app instead of letting the system decide on its own.
Switch Between Navigation Buttons and Gestures
If the three navigation buttons at the bottom of your Oppo phone take up screen space or the swipe gestures keep triggering by accident, you can switch between both control modes at any time. ColorOS lets you pick virtual buttons or full-screen gestures depending on how you actually hold and use your phone.
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.
Turn Keyboard Vibration On or Off
If typing on your Oppo phone feels silent even though you want tactile feedback, or the opposite happens and every tap buzzes when you want quiet, the keyboard has its own vibration setting separate from your system sound menu. Oppo devices run Google's Gboard by default, and its haptic feedback toggle is often confused with the general vibration options elsewhere in the phone. Even with the toggle switched on, the vibration level itself can still be set to zero, which mutes the effect completely.
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.
Change Alarm Sound
If your alarm still plays the same default tone every morning on your Oppo phone, you probably have not touched the Ringtone option inside the Clock app yet. Many users also expect the smart alarm tone to adjust automatically, but that only works once it is switched on separately. Without editing the sound assigned to each alarm, ColorOS keeps reusing the same melody for every wake-up time.
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 Google Voice Typing On or Off
If a microphone icon keeps showing up on your Oppo keyboard even though you never asked for voice input, Google voice typing is active by default under ColorOS. It sits inside the keyboard settings alongside your regular input method, so many users only notice it once they tap it by accident. You can switch it off there, or turn it back on if speech input disappeared after an update.
Schedule Power On/Off
If you want your Oppo phone to turn on or off at a fixed time every day without pressing the power button, ColorOS has a built-in scheduler for that. Many users miss this option because it sits inside a secondary settings menu rather than the main power settings. Without it enabled, you have to manually power the device on and off every single day.
Change Personal Hotspot AP Band (2.4 GHz / 5 GHz)
If your Oppo hotspot feels slow or drops connections when several devices join, it is probably still running on the 2.4 GHz frequency. Many Oppo phones can broadcast on 5 GHz instead, which gives connected laptops and tablets more bandwidth over shorter range. The switch has to be made manually, since the hotspot defaults to 2.4 GHz every time.
Turn Flashlight On or Off
Searching your app drawer for a flashlight icon on your Oppo phone gets you nowhere. Coloros does not ship a standalone flashlight app, so the toggle sits hidden inside the quick settings panel instead. Anyone coming from a different Android skin usually looks in the wrong place first.
Restrict App Data Usage
Some apps on your Oppo phone keep syncing in the background and quietly burning through your mobile data plan, even when you are connected to Wi-Fi. That happens because ColorOS grants every app internet access on both networks by default, unless you change it manually. This shows up most with apps that auto-update or stream content without asking first.
Auto Switch Between Wi-Fi and Mobile Data
If your Oppo phone keeps stalling on a weak Wi-Fi signal instead of jumping to mobile data, the Wi-Fi Assistant feature is either switched off or mobile data itself is disabled in the background. Videos buffer, messages send late, and apps time out even though the Wi-Fi icon still shows a connection. This setting decides whether your phone hands over to mobile data automatically once Wi-Fi quality drops.
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.
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.
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 Auto-capitalization On or Off
If sentences and random words get capitalized automatically while you type, Gboard's auto-capitalization is switched on and reacting to every full stop or new line. On Oppo phones this text correction option often catches names, abbreviations or chat messages where you want a lowercase start. Turning it off stops Gboard from capitalizing the first letter after punctuation and at the beginning of each sentence.
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.
