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 the Emoji Switch Key on Gboard
On Oppo phones with Gboard, an emoji icon sits next to the space bar by default, letting you jump straight into emojis while typing. If you rarely use it, or you actually need that spot for the language switch button instead, the emoji key gets in the way. Both buttons cannot be shown at the same time, so one always replaces the other.
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.
Send a Photo via Bluetooth
A photo from the camera or Gallery does not reach a paired device automatically, and the Bluetooth send option is easy to miss inside the sharing menu. Bluetooth transfer only works once a device is paired and switched on, but the actual command sits in the Send sheet, not in the Bluetooth settings screen. The same process applies to PDFs, videos, contacts and other file types, not just photos.
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.
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 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.
Change Contacts Name Format (First/Last Name Order)
If your contacts list shows first name before last name and you need it reversed, the sort order comes from a setting inside the Contacts app, not your phone's system settings. This affects how names appear in calls, messages, and the contacts list alike.
Clear the Entire Call Log
If your Oppo call list keeps piling up with old numbers, missed calls, and duplicate entries, finding a recent call becomes harder every week. Since the Call history screen mixes calls and messages together, a full log can make it tricky to spot what actually matters. Clearing it out gives you a clean list again without touching your saved contacts.
Allow Repeated Calls in Do Not Disturb
Urgent calls from the same number can go straight to silence when Do Not Disturb is active on your Oppo phone. ColorOS has a built-in exception that lets a second call within three minutes ring through, but it stays switched off until you turn it on yourself. Without it, every call gets muted the same way, no matter how often someone tries to reach you.
Set a Custom Notification Sound
If every notification on your Oppo plays the same generic chime, the built-in sound list is probably too limited for you. Sound settings on ColorOS include a Select from files option that scans your phone's storage for compatible audio automatically. That means you can assign your own MP3 as a notification tone instead of picking from the default set.
Allow Display Over Other Apps
When Messenger, Facebook chat heads or a call app refuse to pop up on top of other apps, the floating windows permission on your Oppo phone is usually switched off. Without this permission the app can only run in the foreground and loses its quick-access overlay. This affects chat bubbles, screen recorders and any tool that needs to draw over your current screen.
Enable High Contrast Text
Small system fonts on Oppo phones can be hard to read in bright light or for users with low vision. The 'High contrast text' option in Accessibility boosts contrast between letters and background without changing the actual font size. If the toggle stays hidden, it usually sits inside a submenu that is easy to overlook.
Turn Mono Audio On or Off
If you only wear one earbud or rely on a single-ear headset, Oppo's default stereo playback can cause you to miss dialogue, notification tones, or background sounds that are mixed to the other channel. This shows up during calls, videos, and games where audio cues are split left and right. Mono audio fixes this by merging both channels into one identical signal.
Turn On or Off the Keyboard Suggestion Strip
If a row of word suggestions keeps popping up above the keyboard while you type, that is the suggestion strip built into Gboard. Oppo phones ship with this bar switched on by default, and tapping a suggested word drops it straight into your text. If the constant suggestions distract you or make typing feel cluttered, you can turn the strip off in the keyboard settings.
Make a Phone Call
Switching between the Phone app and Contacts can be confusing when you just want to dial a number fast on your Oppo device. New users often do not realize there are several ways to start a call, and dual-SIM devices add an extra step that trips people up. This guide walks through the fastest route to get a call connected.
Add a Wi-Fi Network Manually
If a Wi-Fi network does not show up in the list of available connections, you cannot just tap and connect like usual. This happens when a router hides its SSID broadcast or when the signal is weak enough that Android drops it from the scan results. To connect anyway, you need the exact network name and, if the router uses one, the correct password.
Activate a Downloaded Keyboard
After installing a new keyboard app on your Oppo phone, the system keeps typing with the default keyboard instead. ColorOS keeps every input method, including downloaded keyboards and voice typing, switched off until you turn it on yourself in one central menu. Without that extra step, the new keyboard app sits on your home screen but never appears when you tap a text field.
