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.
Enable Mobile Data During Calls on Secondary SIM
If your internet drops the moment you pick up a call on your primary SIM, the secondary SIM's mobile data connection is probably not allowed to take over. On dual-SIM Oppo phones this behavior is controlled separately from your normal data SIM selection, so browsing can stall mid-call even though you have a working data plan on the other slot.
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.
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.
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.
Change Keyboard Theme (Gboard)
If your Oppo keyboard still shows the same default look, that is because Gboard hides its theme options outside the main keyboard settings. Color combinations, gradients, and even your own photos as a background are available, but only once you know where to look.
One-Handed Mode: Turn On or Off
Reaching the top corners of a large Oppo screen with a single thumb is often impossible, especially when you are holding a bag or standing on a train. One-Handed mode shrinks the whole interface into a smaller window so every icon stays within thumb range. Many users only discover this option by accident inside the Quick settings panel.
Stay on the Lock Screen After Face Unlock
When you press the power button on an Oppo phone, Face unlock often skips the lock screen entirely and drops you straight onto the home screen. That means you never get to check notifications, the clock, or widgets before the phone unlocks. The setting responsible for this behavior sits inside the Face recognition options and is easy to miss.
Turn Vibrate on Touch On or Off
If your Oppo phone buzzes every time you tap the navigation bar, open a menu, or dial a number, the touch feedback vibration is switched on. This system-wide haptic response can feel excessive on Coloros, especially when it triggers during simple actions like scrolling through settings or answering calls. You can turn it off without changing your ringtone or notification vibration settings.
Show or Hide Battery Percentage in Status Bar
If your Oppo phone only shows a battery icon in the status bar, you can't tell exactly how much charge is left. The icon shape changes as it drains, but it never tells you whether you're at 42 percent or 58 percent. Coloros hides the exact number by default, so you're stuck guessing from the icon alone.
Change Fingerprint Animation
When you unlock your Oppo phone with the in-display fingerprint sensor, a small animation plays over the icon. If you want a different visual style instead of the default effect, ColorOS lets you switch it, though the exact options shown can differ between ColorOS versions and models.
Show or Hide RAM Info in Recent Tasks
When you swipe through open apps on your Oppo phone, the Recent tasks screen only shows app previews by default, with no memory data at all. If you want to see how much RAM is currently in use without opening a separate app or tool, that information stays hidden until you switch it on in Coloros.
Remove a Keyboard Language from Gboard
If you added several keyboard languages to Gboard on your Oppo phone, swiping through them or long-pressing the spacebar to switch gets tedious fast. Unused languages also clutter the language switcher and can throw off autocorrect suggestions. The cleanup option sits inside the keyboard app itself, separate from the general system language settings.
Customize Smart Sidebar Quick Access
If your Oppo's Smart Sidebar is packed with tools you never open, or missing the one app shortcut you actually need, the Quick access list needs an edit. The sidebar mixes three shortcut types: Quick Tools like screenshot or screen recording, Quick Apps that open in a floating window, and plain App shortcuts. Left unedited, you keep swiping past icons that only get in the way.
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.
App Drawer: Turn On or Off
New apps on your Oppo landing straight on the home screen instead of a separate app list usually means the App Drawer is switched off. Without it, every install adds another icon to your screen, and there is no dedicated overview to browse through installed apps. On ColorOS this behavior is controlled through the home screen layout mode, not a standalone app-drawer toggle.
Turn Lock Screen Notifications On or Off
If notifications keep showing full message previews on your Oppo lock screen, the 'Lock screen notifications' option is likely set to display title and body for that app. ColorOS handles this setting per app, so one app can stay silent while another still alerts you. Left on the default, anyone who glances at your phone can read message content before you unlock it.
Set Dark or Light Theme for the Messages App
If the Messages app on your Oppo phone still shows a bright white background at night, it is running the light theme regardless of your system-wide dark mode setting. Coloros lets you set the theme for Messages on its own, which cuts glare and can lower battery drain on OLED screens. This option sits inside the app itself, not in the general display settings.
