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.
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.
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.
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.
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 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.
Turn On or Off Flip to Mute Incoming Calls
If your Oppo phone keeps ringing loudly during meetings even after you flip it face-down on the table, the flip-to-mute gesture might be turned off. This gesture silences an incoming call the moment the screen faces down, but only when it is enabled in the gesture settings. Some users also find the opposite problem: calls go silent unexpectedly whenever the phone lies flat.
Turn Always-On Display On or Off
If your Oppo screen stays completely black when locked, or notifications never appear on it, the Always-On Display setting is likely involved. This feature can show time, date and battery level permanently or on a schedule, and on newer ColorOS versions also notification icons. Whether it is active, and how much it shows, depends on a toggle that is easy to overlook in the display settings.
Move Apps and Files to an SD Card
When internal storage on your Oppo phone runs low, photos, videos, and even some apps stay stuck on the device even though an SD card is installed. Coloros includes a built-in transfer tool, but it only works with certain file types and not every app is eligible for the move. Knowing which data can actually shift to the memory card helps you free up space without deleting anything you need.
Turn Off TalkBack (Accessibility)
If TalkBack is running on your Oppo phone, a single tap only selects an item and reads it aloud instead of opening it. Every action now needs a confirming second tap, which makes even switching TalkBack off feel out of reach. This select-then-confirm control catches most users off guard exactly when they try to disable the feature.
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.
Change Media Volume
If videos, games or music play louder or quieter than expected on your Oppo phone, the media volume slider is usually the cause, not the ringtone or notification volume. This level controls audio for apps and their content separately from calls and alerts. On some ColorOS versions the volume buttons only adjust it while media is actively playing.
Access Scientific Calculator Functions
If the Calculator app on your Oppo phone only shows basic addition and multiplication, functions like sine, cosine and tangent seem to be missing entirely. Many users assume Coloros ships without a scientific mode, when it is actually built into the same app and just hidden from view. This becomes a problem the moment you need quick trigonometry or advanced math on the go.
Change Ringtone
Stuck with the same default ringtone on your Oppo phone and want something else for calls? Coloros lets you pick from built-in tones, but on dual SIM devices each SIM number can carry its own separate sound. Missing this per-SIM setting is why some calls still ring with the wrong tone even after changing it once.
Reset Camera Settings to Default
If your Oppo camera app looks off after tweaking resolution, grid lines, watermark or video quality, tracking down every changed option one by one gets tedious fast. Filters, saved modes and exposure tweaks can pile up until the app behaves unpredictably. ColorOS includes a single function that reverts every camera option at once instead of making you undo each change manually.
Pair a Bluetooth Device
Turning on Bluetooth on your Oppo phone does not automatically connect it to headphones, speakers, or another phone. Both devices still need to confirm the connection before any file transfer or audio streaming works. If your Oppo phone cannot find the other device or the pairing request never appears, the two devices are simply not linked yet.
Block or Unblock a Contact
If a contact keeps calling or texting you and you want it to stop, blocking them cuts off calls and messages without deleting the contact. On Oppo phones this option sits inside the Contacts app rather than a dedicated blocklist screen, so it is easy to overlook. Unblocking later restores calls and texts from that number right away.
Turn Power Saving Mode On or Off
If your Oppo phone suddenly dims the screen, cuts the screen timeout to 15 seconds, and stops apps from syncing in the background, Power saving mode is active. This mode can switch on by itself at low battery or stay on after you enabled it manually, and it often delays notifications and app updates. Switching it off brings back normal brightness and sync behavior right away.
Change Time Zone Manually
If you swap SIM cards or connect to a foreign network, your Oppo phone often jumps to the wrong time zone on its own. Clock apps, alarms and message timestamps can then be off by hours, because Coloros pulls the zone from the current network instead of your actual location.
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 On/Off Autofill Service
If a form keeps suggesting old addresses, outdated passwords, or the wrong Google account whenever you tap a field, the Autofill service on your Oppo phone is likely still linked to a provider you no longer want active. This often happens after switching Google accounts or installing a password manager that never became the default. Turning the current service off - or picking a different one - is the only way to stop the wrong data from popping up.
Change Home Screen Grid Size
If your Oppo home screen feels cramped with too many icons squeezed into each row, or the tiles look oversized with too few apps per screen, the grid layout is set to a fixed size. Coloros offers several grid options, usually starting with 4x6 and 5x6, and some models add extra layouts. Picking the wrong size can cut off app names or leave large empty gaps between icons.
