Hide and Show Apps on the Home Screen
Anyone can open your banking or messaging app just by tapping its icon on the home screen. Coloros lets you hide selected apps behind a password prompt, but the setting sits inside the Privacy menu and is easy to overlook. Once an app is hidden, it disappears from the app drawer and only reappears after you unlock it through a hidden code.
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 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.
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.
Set Alarm Ring Duration
If your Oppo phone's alarm cuts off after just 5 minutes and you keep sleeping through it, the ring duration is still on the default setting. You can stretch it up to 30 minutes or shorten it to as little as 1 minute, depending on how deep a sleeper you are.
Turn Data Saving On or Off
If background apps on your Oppo phone suddenly stop syncing or notifications arrive late, Data Saving mode is likely blocking their mobile data access. Even apps you are actively using can load slower or skip previews and thumbnails while the mode is active. This setting sits inside the mobile data menu and is easy to miss when troubleshooting connectivity issues.
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.
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.
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.
Dark or Light Theme for the Phone App
If the Phone app on your Oppo still opens in a bright white interface at night, it can strain your eyes and drain the battery faster than needed. Unlike the rest of ColorOS, the dialer and call screen sometimes keep their own display setting separate from the system-wide dark mode. Switching it manually only takes a few taps.
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 Up a VPN Connection
If your company or university hands you server details instead of a ready-made VPN app, your Oppo phone needs a manual profile entered directly in the system settings. Without the right protocol, server address and login data, the connection fails silently or drops right after you save it. This is different from installing a VPN app from the Play Store, which handles the setup on its own.
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.
Answer an Incoming Call
If a call pops up on your Oppo and tapping the screen does nothing, you are probably looking for the wrong gesture. Oppo phones show incoming calls as a full-screen alert rather than a simple tap-to-answer button, which confuses anyone switching from a different Android brand.
Turn Off App Lock
If Oppo's App lock keeps asking for your privacy password every time you open a protected app, that extra step gets old fast. Turning off App lock releases all currently locked apps and their data at once, so the password prompt stops appearing. You still need to confirm your privacy password to make the change.
Turn Screencast On or Off
If your Oppo screen does not show up on the Smart TV or another display, Screencast is often switched off or the target device is missing from the list of available receivers. Screencast mirrors your phone screen over the network, but it only works once the feature is enabled on the Oppo and the other device is discoverable. Without that active connection, nothing gets transmitted even if the TV is on and ready.
Change App Icon Style
If every app icon on your Oppo still shows the same rounded-square outline, the built-in icon shape picker probably has not been touched yet. Coloros lets you switch all home screen icons at once between styles like standard, material, pebble, or a custom outline. The setting is easy to miss because it sits inside general appearance options rather than the home screen settings themselves.
Change Default Messaging App
If Messenger or another chat app keeps hijacking your text messages, Coloros still only lets one app act as the default SMS handler at a time. Several installed apps can request that role, which is why replies to notifications sometimes open the wrong client. Oppo controls this behavior through a single setting in the app management area, separate from the messaging apps themselves.
Enable Vibration in Silent Mode
Switching your Oppo to silent mode also kills the vibration, so you miss calls and messages without any signal at all. ColorOS does not have a separate vibrate mode like stock Android, so silent and vibrate are tied together unless you change one setting. Once you know where to look, you can keep your phone quiet but still feel it buzz.
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.
Show Connection Speed in Status Bar
If you keep opening the data usage screen just to check how fast your connection is, Oppo can show that number right next to the signal icon instead. On Coloros this real-time network speed indicator is switched off by default, so the status bar only displays signal strength and battery. Turning it on adds a live Mbps or KB/s reading that updates while you browse or stream.
