Set Default App Storage to SD Card
Running out of internal storage on your Oppo phone while the SD card sits mostly empty? You cannot install apps directly onto the memory card, but many apps let you redirect new data to it once you set the card as the default storage target. Whether this actually frees up space depends on whether the app itself supports external storage.
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.
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.
Export Contacts to a vCard File
On Oppo phones running ColorOS, the built-in export tool only saves contacts to local phone storage, not directly to a cloud service or another device. The result is a single .vcf file containing every contact detail, and you get to pick which account's contacts go into it. If you expected a direct transfer option, this local-only behavior can be confusing.
Allow Calls During Do Not Disturb
If Do Not Disturb is active on your Oppo phone, calls get silenced unless you add an exception. You can choose to let calls through from everyone, only from saved contacts, or from a handful of selected people. Missing this setting means important calls go straight to silence with no ring at all.
Custom Notification Sounds per App
If every app on your Oppo phone plays the same generic notification tone, it gets hard to tell a chat message apart from a calendar reminder just by sound. Coloros lets you assign a separate ringtone to each app, but the option sits inside app management instead of the general sound settings. Many users only ever find the global tone switch and assume individual app sounds are not possible.
Turn Split Screen On or Off
If a three-finger swipe up does nothing on your Oppo phone, split screen mode might be switched off in the background. ColorOS ships with the feature active out of the box, but the gesture only works while split screen itself stays enabled in the settings.
Show or Hide Password Characters While Typing
On Oppo phones, the last character you type into a password field briefly shows up on screen instead of staying hidden behind dots. That's handy for spotting typos, but it can expose your password if someone else is looking at your screen. Whether this happens depends on a single toggle buried in your security settings.
Unlock Private Safe with Fingerprint
Typing in your privacy password every time you want to check files in Private Safe gets tedious fast. Oppo phones let you swap that PIN, pattern or password entry for a fingerprint tap, but the toggle sits buried inside biometric settings and stays off by default. Without switching it on, the fingerprint sensor you already use to unlock your phone has no effect on the vault.
Remove an App Shortcut from the Home Screen
If a shortcut icon refuses to disappear when you try to clean up your Oppo home screen, the App Drawer setting is usually the reason. With App Drawer enabled, removing a shortcut only deletes the icon, not the app. Without it, home screen icons and installed apps are the same thing, so removing one uninstalls the other.
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.
Delete Photos or Videos
Storage fills up fast when old photos and videos pile up in the Oppo Gallery app, and deleting them one by one feels endless. Switching to edit mode lets you select several files at once, but the items you remove do not disappear right away. They sit in the Trash for a while first, which still counts against your free storage until they are cleared out.
Turn On or Off Video Subtitles
Videos with subtitle tracks often play without any captions showing up on an Oppo phone, because the subtitle option is switched off by default. If you rely on captions for language learning, noisy environments, or hearing support, this can make watching content frustrating until the right accessibility setting is found.
Check for Software Updates Manually
If your Oppo phone hasn't picked up a new ColorOS version yet, waiting for the automatic background check can take days. The system only looks for firmware at set intervals, so a pending patch or security fix might sit unnoticed for a while. Triggering the check yourself confirms right away whether a new update is actually available.
Turn On/Off Call Barring
If certain calls still get through even though you set up barring, or international calls stay blocked after you land back home, the wrong barring option is probably still active on your Oppo. Call barring works per call type, so outgoing calls, outgoing international calls, roaming calls and incoming calls each have their own separate switch. On dual-SIM devices this gets confusing fast, since barring is configured per SIM card.
Turn High Performance Mode On or Off
If your Oppo phone drains battery fast or feels hot during gaming, High Performance Mode might already be active in the background. This setting disables every energy-saving feature to push maximum speed, which trades battery life and temperature for smoother performance.
Set Up a Proxy Server for Wi-Fi
If you want to browse without exposing the real IP address of your Oppo phone, a proxy server routes your traffic through a different address. Without one set up, every app and website still sees your actual connection details. A proxy only works once you are already connected to a Wi-Fi network.
Turn Glide Typing On or Off
Typing every letter by hand feels unnecessary when Gboard can turn a single finger swipe across the keyboard into a full word. On some Oppo phones, Glide typing stays switched off by default, so swipe gestures do nothing and the keyboard falls back to individual key taps. Whether you want faster input or need to stop an accidental swipe trigger, the setting sits hidden inside the keyboard menu.
Add Trusted Devices for Smart Lock
If your Oppo phone still asks for a PIN even though your smartwatch or Bluetooth headset is connected, Smart Lock likely does not have that device listed as trusted yet. Trusted devices keep the phone unlocked automatically as long as the Bluetooth connection to a paired accessory like a fitness tracker, car handsfree, or headphones stays active. Pairing alone is not enough - the accessory has to be added to the trusted list before automatic unlock kicks in.
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.
Change Privacy Password
Switching from a PIN to a pattern for your Oppo privacy password, or just unsure which type you originally picked? The privacy password guards hidden files and cloned apps separately from your screen lock, so updating it means confirming the current one before you can set a new type.
Set Sound and Vibration for Calendar Reminders
When a calendar reminder pops up on your Oppo phone, it usually plays the same ringtone and vibration pattern as every other notification. That makes it hard to tell at a glance whether an alert came from Calendar or from a chat app. You can give Calendar reminders their own tone and vibration so they stand out.
Turn Off Notifications for a Single App
If one chatty app keeps flooding your lock screen while everything else stays quiet, a blanket notification toggle wont fix it. On ColorOS you can allow or block alerts per app instead of turning notifications off system-wide.
Add Members to a Contact Group
Creating a contact group on your Oppo phone does not lock the member list. If you forgot someone or need to add a person later, the group only updates once you open it again and confirm the new members through the add-contacts screen. Skipping that confirmation step leaves the group unchanged even though it looked like the contact was added.
