Add Trusted Places to Smart Lock
If your Oppo phone keeps asking for a PIN or pattern even at home or in the office, Smart Lock's Trusted Places feature is probably not configured yet. Without a saved location, the phone falls back to your regular screen lock everywhere, including places you visit every day. Trusted Places keeps the device unlocked within roughly 50 meters of a spot you pick, as long as location services stay on.
Set an Alarm with Custom Repeat and Ringtone
On Oppo phones several alarms exist side by side, each with its own repeat pattern, snooze length, vibration and ringtone. When you set up a new alarm or edit an existing one, it is easy to miss where these individual options actually live and end up with the wrong sound or repeat days. This mixes up daily wake-up alarms with one-off reminders.
Change Start of Week in Calendar
If your Oppo calendar always opens on the wrong weekday, the region-based Start of the week setting is usually the cause. This throws off the weekly grid in the Calendar app, which gets confusing if you are used to a different day as the first one. You can pick Saturday, Sunday or Monday to match your own routine.
Volume Buttons Function for Camera
On Oppo phones, pressing a volume button while the Camera app is open takes a photo instead of adjusting the sound level. This happens because Coloros assigns the buttons to shutter control by default, and the same option can be switched to zoom instead.
Turn Personalized Ads On or Off
Every Oppo phone carries a unique Advertising ID that networks use to build a profile from your app usage and browsing habits. If ads keep following you across unrelated apps with oddly specific products, that identifier is the reason. You can either reset this ID for a fresh start or opt out of ad personalization completely.
Adjust Touch & Hold Delay
If long-pressing icons or text on your Oppo feels either too twitchy or too sluggish, the touch-and-hold timing is likely set wrong for your habits. This delay controls how long you need to press before the system registers a touch and hold instead of a normal tap.
Turn Call Vibration On or Off
Every incoming call makes your Oppo phone buzz, even when you already picked a ringtone you like. If that vibration feels distracting, unnecessary at your desk, or drains the battery faster during calls, the toggle for it lives inside your sound settings, not in a separate ringtone menu.
Turn On/Off Game Space
If calls still ring through during a match or notification banners keep popping up over your game, Game Space is probably switched off or one of its assistant options got disabled. This toggle controls whether Oppo's game launcher actively manages calls, alerts and performance while you play. Getting it wrong either way means either constant interruptions or a launcher that keeps popping up when you do not need it.
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.
Clear App Cache
If an Oppo app keeps loading outdated images, freezes, or your storage fills up faster than expected, a bloated app cache is often the reason. ColorOS stores temporary files like thumbnails and login data so apps open faster, but old or corrupted cache entries can trigger glitches or slow performance. Clearing the cache removes this leftover data without deleting your photos, documents, or app settings.
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.
Export Contacts to a vCard File
On Oppo phones running ColorOS, the built-in export tool only saves contacts to local phone storage, not directly to a cloud service or another device. The result is a single .vcf file containing every contact detail, and you get to pick which account's contacts go into it. If you expected a direct transfer option, this local-only behavior can be confusing.
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.
Turn On/Off Select to Speak
When Select to Speak is active, an extra accessibility icon shows up in the navigation bar, and tapping it lets you highlight any text on screen to have it read aloud. It works similar to TalkBack but does not take over your phone's regular touch controls. If that icon suddenly appears or disappears without you doing anything, the setting may have been toggled by accident during a system update or a shared accessibility shortcut.
Edit Quick Decline Messages
When you reject an incoming call with a quick text, Oppo phones send one of four preset replies like 'Sorry, I can't answer the phone now.' These default lines rarely match how you'd actually respond to family, friends, or coworkers. Coloros lets you rewrite all four texts, but the setting sits inside the phone app rather than Messages.
Search for a Word in a Conversation
Scrolling through a long chat history just to find one message wastes minutes, especially in group chats with hundreds of texts. Oppo's Messages app has a search function that works inside a single conversation, not just across your whole inbox. Every match gets highlighted so you can jump straight to the message you need.
Turn Screen Rotation On or Off
If your Oppo screen refuses to switch to landscape when you turn the phone, or it flips around when you'd rather it stayed still, the Auto-rotate function is usually the cause. This setting depends on the built-in position sensor and can be changed either in the system settings or right from the quick settings panel. Some apps ignore this setting entirely and force their own orientation regardless of what you pick.
Turn Chat Features On or Off in Messages
If your Oppo phone still sends plain SMS instead of read receipts, typing indicators or media previews in Messages, Chat features are probably switched off. Some carriers activate this RCS-based mode automatically, others leave it for you to enable manually. Turning it off again can also fix message delivery problems on certain networks.
Turn On/Off Magnification (Accessibility)
If text and icons on your Oppo phone are too small to read comfortably, the built-in magnification tool works like a digital magnifying glass. A triple tap on the screen opens a zoom window that you control with a two-finger pinch. The feature covers the entire display except the keyboard and navigation bar, and many users cannot find where to switch it on or off.
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.
Change Fingerprint Animation
When you unlock your Oppo phone with the in-display fingerprint sensor, a small animation plays over the icon. If you want a different visual style instead of the default effect, ColorOS lets you switch it, though the exact options shown can differ between ColorOS versions and models.
Create an Event in Calendar
The Calendar app on Oppo smartphones lets you create events, but also goals, reminders, and tasks from the same menu. Each entry type asks for different fields, so picking the wrong one can mean missing a location box, a due date, or a reminder toggle later.
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.
Sync Calendar Manually
If new appointments or updated events on your Oppo phone do not show up right away, the Calendar app has not run its automatic sync yet. This mostly happens with entries added right after you last opened Calendar, since Coloros only refreshes data on launch or on its own schedule. A manual sync fixes this without waiting.
