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 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.
Force Stop an App
When an app on your Oppo phone freezes and stops reacting to taps, swiping it away in the recent-apps view often just hides it while the process keeps running. Force stop ends that process directly, similar to Stop task on a Windows PC. Because it kills the process without saving anything, you usually land on a login screen the next time you open the app.
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.
Turn Find My Device On or Off
If your Oppo phone goes missing, a deactivated Find My Device feature means you lose any chance to track, lock, or wipe it remotely. Many users only discover the toggle is off after the device is already gone, since it sits inside the Security menu rather than a separate app. Checking its status now takes less than a minute and closes that gap before it becomes a problem.
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.
Manage Google Activity Controls
If you have not touched the Activity controls on your Oppo phone, Google keeps logging Web & App Activity, location history, YouTube history and more under the Google Account you are signed into. This tracking runs in the background and is not obvious from the main Settings screen. Left untouched, it builds a detailed profile of what you search, watch and where you go.
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.
Turn Google Play Protect On or Off
If Google Play Protect keeps blocking an app you trust or throws a warning notification every time you install something, the built-in scanner is doing its job a bit too aggressively. On Oppo phones this security check runs in the background by default and can interfere with sideloaded apps or apps from outside the Play Store. Turning the scan off, or back on, changes how much control Android has over what runs on your device.
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.
Enable App Lock
Anyone who picks up your unlocked Oppo phone can open banking apps, chats, or your gallery without another prompt. Coloros includes an app lock feature that adds a separate privacy password in front of individual apps, but it stays switched off until you activate it. Without this extra layer, sensitive data stays only one tap away.
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.
Turn Usage & Diagnostics On or Off
If your Oppo phone keeps sending usage and diagnostic data to Google without a clear reason, the toggle for it sits deep inside the privacy menu and gets overlooked easily. This data includes device performance details, crash reports and app usage patterns, even though Oppo does not fully disclose everything that gets collected. Turning the option off stops the automatic sharing, but you also lose the small contribution to future Android stability fixes.
Rearrange Quick Settings Icons
If your Quick settings panel feels cluttered or the toggle you reach for most sits on a second screen, the icon order on your Oppo probably still matches the factory layout. ColorOS lets you add, remove and reorder these buttons, but the edit mode is easy to overlook since it hides behind a small pencil icon in the panel itself. Between eight and sixteen icons fit here depending on your model, and a messy order slows down quick access to Wi-Fi, flashlight or Bluetooth.
