Turn Wi-Fi On or Off
If your Oppo phone won't connect to your home router or a public hotspot, the Wi-Fi radio itself might be switched off or stuck in a weird state. This also happens after a system update, when the toggle looks active but no networks show up. Before troubleshooting a specific network, it helps to confirm Wi-Fi is properly enabled or fully disabled first.
Turn On-body Detection On or Off
Your Oppo phone stays unlocked the whole time you are carrying it, even after you slide it into a pocket or bag. That is On-body detection at work, a Smart Lock feature that reads motion sensors instead of checking who is actually holding the device. If someone else picks up your phone while it is still moving, they get straight in without a PIN or fingerprint.
Add Emergency Contacts for Emergency SOS
If Emergency SOS or emergency SMS on your Oppo phone only reaches the default 112 number, no personal emergency contact is stored yet. Without at least one saved contact, alerts and location messages during an SOS trigger won't go out to anyone you know.
Turn Bluetooth Tethering On or Off
If a paired device cannot reach the internet through your Oppo phone, Bluetooth tethering might be switched off or the device connection was never approved. This function shares your mobile data over Bluetooth instead of Wi-Fi hotspot or USB, which helps laptops without hotspot support and saves battery compared to Wi-Fi sharing. Each paired device needs the option allowed on its own before data actually flows.
Turn Notification Badges On or Off Per App
If notification badges do not show up on some app icons on your Oppo home screen, the per-app Badge toggle is likely switched off. ColorOS only displays a small dot instead of a number, and each app has its own switch tucked inside the notification settings. Missing dots often get mistaken for a wider notification bug when it is really just this one setting.
Show or Hide Birthdays in Calendar
Birthdays from your contacts do not always show up in the calendar app on an Oppo phone, even though the dates are stored correctly in your Google account. Usually the birthday calendar layer is just switched off or the sync has not caught up yet. This affects anyone who wants a quick overview of upcoming birthdays without opening the contacts app separately.
Change Google Backup Account
If your phone backs up to the wrong Google account, storage on that account can fill up fast or you may not find your backup when setting up a new device. This mix-up usually happens after switching Google accounts on the phone without updating the backup destination in Storage and Backup. The good news is the backup account is not locked in and can be swapped at any time.
Resize a Widget on the Home Screen
If a widget on your Oppo home screen only shows a fixed size and won't stretch right after you add it, that's expected. Coloros only unlocks resize handles once the widget is already sitting on the screen, not while you're still picking it from the widget drawer. That's a different flow than on stock Android, where some launchers let you size a widget before you even drop it.
Schedule Dark Mode Automatically
Switching Dark mode on and off by hand every day gets old fast, especially if you forget it at night and the screen stays bright. ColorOS lets you set fixed times so light and dark mode change on their own, but the option is easy to miss inside the display settings.
App Download Preference (Wi-Fi or Mobile Data)
New apps from the Google Play Store only download over Wi-Fi on your Oppo phone by default, and a large install can sit there waiting instead of finishing over mobile data. This is controlled by a setting inside the Play Store itself, not by Coloros. You can allow downloads over mobile data at any time, or set the Play Store to ask you every single time before it uses cellular data.
Display Short Calendar Entries as 30-Minute Blocks
When a day view is packed with quick appointments, entries lasting just a few minutes can shrink into thin slivers that are hard to read or tap. The Google Calendar app on Oppo phones has a display option that stretches these short entries so they take up the same visual space as a standard half-hour slot. Without it enabled, brief tasks and reminders often get buried between longer events.
Disable Automatic Power Saving Shutoff After Charging
If Power saving mode on your Oppo phone switches off by itself once the battery reaches roughly 60 percent, ColorOS is applying its built-in reset rule. That can be annoying if you want reduced performance and background limits to stay in place no matter how much charge is left.
Sort Call History by First or Last Name
If your call log on an Oppo phone lists contacts in a mix of first-name and last-name order, finding a specific call gets tedious. The Google Phone app controls this through a display setting that is easy to overlook. Switching the sort order fixes the call list and call history at once.
Edit a Contact
When a phone number changes or a name is misspelled, the stored contact still shows the old details until you update it manually. This mix-up often causes calls or messages to go to the wrong entry, especially if the contact was synced from an old backup. Coloros lets you correct any field directly from the contact card without deleting and re-adding the entry.
Block Calls and Notifications in Game Space
When you are deep into a match, an incoming call notification can pull you straight out of the game or slow down your device. On Oppo phones this happens because Game Space treats calls and notifications the same way it treats other interruptions, unless you tell it otherwise. Only apps added to the Game Space launcher are affected by this behavior.
Add Email Account
If new mail from Gmail, Outlook, Yahoo or an Exchange server never shows up in your inbox app, the account itself is often missing from the phone, not just from the mail app. Oppo phones need every provider registered once in the account manager before Coloros can sync mail, contacts and calendar entries for it. Without that step, the inbox stays empty or keeps asking you to log in again.
Rename a Contact Group
If a contact group still shows an old team name or a typo, it can confuse you every time you scroll through your address book on your Oppo phone. The label does not update on its own and stays until you change it manually. Coloros lets you fix this directly inside the Contacts app.
Delete a Contact Group
Deleting a contact group on an Oppo phone with Coloros only removes the group label, not the people inside it, and that catches many users off guard. The option sits a few taps deep inside the group menu, so it is easy to tap the wrong entry or miss it entirely. Knowing exactly which group you selected before confirming matters, since the action applies right away.
Filter the Call History List
If your call history on Oppo mixes incoming, outgoing and missed calls together, spotting who you failed to reach gets tedious once the list grows. The phone app hides a filter that narrows the view down to just missed calls. Without it, you end up scrolling through every entry to find what you actually need.
Restore a Local Backup
If your Oppo phone lost apps, photos or settings after a reset, a failed update, or a storage swap, a local backup can bring that data back without starting from scratch. Local restore lets you pick specific data types instead of overwriting everything on the device. This matters when you only need contacts or messages back and want newer files left untouched.
Tap-to-Capture: Take Photos with a Single Screen Tap
Tapping the screen to frame a shot on your Oppo camera sometimes fires the shutter instead of just setting focus. That happens because Touch to take photo is switched on, so the camera snaps the picture the instant focus locks on the spot you tapped. If you only wanted to adjust focus, this can lead to blurry or mistimed shots.
Remove a Contact from a Group
If a contact group on your Oppo phone still lists someone who left a team or changed roles, you need to remove that entry without deleting the whole contact. Many people only know the single-contact method and never notice the faster group edit mode built into the Contacts app. Removing several members that way, one at a time, wastes time when you need to clean up a whole group.
Turn Auto Brightness On or Off
If your screen keeps getting too dark in bright rooms or too bright at night, the light sensor behind Auto brightness might be misreading your surroundings. Auto brightness is supposed to save battery and reduce eye strain by adjusting the screen on its own, but a dirty sensor, a case covering it, or a stuck setting can throw that off. Once you know where the switch lives, fixing it takes seconds.
Send a Contact's Calls Straight to Voicemail
When one particular contact keeps calling at the wrong moment, muting your whole phone or blocking them outright feels like overkill. Oppo lets you route calls from just that contact directly to voicemail, so your phone stays quiet only for them while everyone else still gets through. The call never rings on your device and the caller hears your voicemail greeting right away, with no delay or extra rings.
