Add Contact to Home Screen
Calling a frequent contact on your Oppo phone often means opening the Phone app, tapping Contacts, and scrolling through the list every time. A home screen shortcut skips all of that and jumps straight to the contact's detail page, ready to call or message in one tap. Useful for family, work, or anyone you contact daily.
Enable or Disable MMS Delivery Reports
If you want confirmation that an MMS actually reached the other person, Coloros has a delivery report option hidden inside the Messages app settings. Many users assume this tells them when the message was read, but it only confirms that the MMS arrived on the recipient's device. On dual-SIM phones the setting also needs to be checked separately for each SIM.
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.
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.
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.
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.
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.
Set Dark or Light Theme for the Contacts App
If the Contacts app on your Oppo still shows a bright white background while the rest of the system already runs in a dark scheme, calls and messages can feel harsh on the eyes at night. This happens because Contacts has its own theme setting, separate from the general display mode. Switching it manually also helps reduce battery drain on screens with an OLED panel.
Import Contacts from a vCard File
Switching to an Oppo phone often means your old contacts sit in a vCard file or on another device, and there is no simple sync button for that. Coloros only lets you import a full .vcf file or pull contacts directly from another phone via Bluetooth, without any option to pick single entries from the list. If you only need a handful of numbers, you end up with everything from the source file instead.
Add a Contact Photo
If your contact list on Oppo still shows plain initials instead of faces, calls and messages are harder to scan at a glance. This happens because no image has been linked to that contact yet in the Contacts app. Adding a photo works with an existing gallery picture or a new snapshot from the camera.
Set Dark or Light Theme for the Calendar App
If Calendar keeps showing a bright white background even after you switch the whole phone to Dark Mode, the app is not following the system setting. Google Calendar on Oppo phones uses its own theme switch, separate from Coloros. This mismatch is common right after a software update or a fresh app install.
Forward a Message on Oppo
Retyping a text just to send it to someone else wastes time, especially when the message contains links or details you cannot easily reproduce. Oppo phones let you forward an SMS straight from the conversation, and you can also send it to a different app instead of another contact.
Mark All Messages as Read
If your inbox fills up with several new texts at once, opening each conversation just to clear the unread badge gets tedious fast. On Oppo phones running ColorOS, the default messaging app lets you clear every unread conversation in one move instead of tapping through them one by one. This works the same way whether the notification badge is stuck at a high number or you just want a clean inbox.
Reject an Incoming Call
If a call catches you at the wrong moment on your Oppo phone, tapping the screen the wrong way can pick up the call instead of declining it. Coloros does not use a simple reject button for this - it relies on a drag gesture on the phone icon, which trips up anyone used to other Android phones.
Delete a Single Text Message
When you want to remove just one text from a conversation on your Oppo phone, tapping and holding brings up a pop-up window, but it is easy to select the wrong option and delete the whole thread instead. This mix-up happens because the delete action behaves differently depending on whether you select one message or several at once. Clearing out old messages this way can also feel slow if you are trying to remove more than a handful.
Send a Group Message (SMS/MMS)
Typing the same text to several contacts one by one wastes time, and Oppo's Messages app doesn't make it obvious how to start a real group thread instead of separate chats. Both the Messages app and the Contacts app can create a group conversation, but the steps differ from a normal one-to-one text. Whether the result becomes an SMS or an MMS depends on what you attach, not on which app you use to start it.
Delete a Single Call History Entry
Deleting your entire call log feels like overkill when you just want one number gone. On Oppo phones a single unwanted entry, like a spam call or an ex-contact, can be removed on its own without touching the rest of your history.
Move Contacts to Another Account
When multiple Google accounts are linked on an Oppo phone, contacts sometimes end up saved under the wrong one, causing missing entries in the app you actually use for calls and messages. This happens because each contact stays tied to the account it was originally created in, even after new accounts get added. Moving a contact to a different account fixes sync and visibility problems without deleting or recreating the entry.
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.
Show or Hide Week Numbers in Calendar
If your Oppo calendar does not show week numbers next to the dates, the setting is simply switched off by default. This option lives inside the calendar app itself, separate from the general phone settings, which is why most people never stumble across it. Without it, planning by calendar week for work or school becomes harder than it needs to be.
