Connect to Wi-Fi via WPS
Typing a long Wi-Fi password on a small keyboard gets old fast, especially with random character strings. If your router supports WPS, your Oppo phone can skip that step entirely and pair using a physical button push instead. This only works while both devices are actively listening for the WPS handshake at the same time.
Turn Web Link Previews On or Off
When you paste a website link into a text, Messages sometimes shows a thumbnail with the page title and image, and sometimes just plain text. This depends on a setting inside the Messages app that decides whether previews load for every link or get skipped entirely. If previews suddenly stopped appearing or you want to disable them for privacy reasons, this option is the one to check.
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.
Turn Automatic MMS Download On or Off
MMS attachments on your Oppo phone often download the moment a message arrives, even over mobile data. On a metered plan that can add unexpected charges before you even open the message. The setting behind this behavior sits per SIM card, which is easy to miss on dual-SIM devices.
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.
Turn On/Off Emergency SOS
If pressing the power button five times keeps launching Emergency SOS by accident, or the shortcut refuses to trigger when you actually need it, the Emergency call quick access toggle is probably set the wrong way. The feature works straight from the lock screen and dials your saved emergency contacts, so an unwanted trigger during everyday use can be just as annoying as a missing one in a real emergency.
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.
Merge Duplicate Contacts
When the same person shows up twice in your Oppo contact list, calls land under one entry while texts go to the other, and you can never tell which number is still current. This usually happens after importing a SIM card, syncing a Google account that already held a copy, or restoring an old backup on top of existing contacts. ColorOS can spot matching names or numbers and combine them into a single record, but it only works if you point it at the right pair first.
Set Up a Privacy Password
If Oppo asks for a privacy password when you try to lock an app or open Private Safe, that code is separate from your screen lock. Many users type in their unlock PIN by mistake and get stuck at the confirmation screen. The privacy password can be its own pattern, PIN, or password.
Allow Messages During Do Not Disturb
When Do Not Disturb is active on your Oppo phone, every incoming message stays silent and hidden on the lock screen, even from people you actually want to hear from. Coloros lets you punch a hole in that silence for everyone, only saved contacts, or just your marked favorites. Without this exception set correctly, urgent texts from family or work contacts get buried until you manually check your notifications.
Mute a Single Conversation
Getting constant buzzes from one SMS thread while every other conversation stays quiet? On Oppo phones running Coloros, notifications are managed per conversation, not just for the whole Messages app. Muting only silences that one thread, it does not archive, delete, or block the contact.
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 or Disable Personal Hotspot
If your Oppo phone won't share mobile data with other devices, the Personal hotspot function under Connection & sharing might be switched off or blocked by a data restriction. Connected phones, tablets, or laptops rely on this Wi-Fi hotspot to get online through your Oppo's data connection. A short auto-off timer or a disabled mobile data connection can also stop the hotspot from working as expected.
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.
Turn Data Roaming On or Off
If your Oppo phone loses mobile data the moment you leave your home network, data roaming is probably switched off. Abroad, mobile data and sometimes calls only keep working once roaming is enabled for the active SIM. Outside the EU in particular, this setting can trigger noticeable extra charges from your carrier.
Rename Home Screen Folders
On Oppo phones, a newly created folder automatically takes the name of whichever app category dominates inside it, but that label often gets cut off after 18 characters. Instead of something useful you end up with a chopped-off word like 'Social Medi' sitting on your home screen. Renaming the folder yourself fixes the display without touching which apps are grouped inside it.
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.
Delete a Photo Album
Deleting an album in the Gallery app on Oppo phones only removes the album folder, not the photos and videos inside it right away. If you expected storage to free up instantly, the fact that contents sit in trash for 30 days can be confusing. Knowing what actually happens to your media helps you avoid losing files you still need.
Set Pop-up Window Display Duration
If a pop-up notification disappears before you can react, or stays on screen longer than needed, the display duration set by the app is the reason. On Oppo phones, each app decides how long its pop-up window stays visible unless you override this with a fixed action time. This becomes noticeable with quick system alerts or app confirmations that flash by too fast to read.
Set Up Private Safe
Storing sensitive photos or documents in the regular gallery on your Oppo phone means anyone who unlocks the device can open them too. Coloros includes a Private Safe that keeps selected files behind a separate privacy password, but it stays inactive until you turn it on yourself. Without that extra step, your files sit unprotected next to everything else on the phone.
Turn Overnight Auto-update On or Off
If your Oppo phone applies system updates without asking, overnight auto-update is likely active. It only installs updates while you are not using the device, between 2 and 5 AM, and only downloads them over WLAN. Turning it off keeps every update on hold until you approve it manually.
Set TalkBack Feedback (Vibration & Sound)
Every keystroke triggers a buzz and a beep because TalkBack feedback is turned on by default on Oppo phones. If typing feels noisy or the vibration drains your focus, the Feedback settings inside TalkBack let you tone it down without turning off accessibility support entirely.
Restart the Smartphone
If your Oppo phone lags, apps freeze, or the touchscreen stops responding for no clear reason, a restart often clears the temporary glitch. ColorOS keeps background processes and cached data running between reboots, and over time these can slow the system down. A quick restart clears that memory without deleting your apps or files.
Turn Dial Pad Tone On or Off
On many Oppo phones the keypad stays completely silent when you tap numbers to dial a call. That is the default behavior in ColorOS, not a hardware fault or a muted ringer. If you want audible feedback while dialing, the option sits inside the sound settings and is switched off until you turn it on yourself.
