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.
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If an Oppo app keeps loading outdated images, freezes, or your storage fills up faster than expected, a bloated app cache is often the reason.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.
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.
Set Default Keyboard Language
If you type in two or three languages on the same Gboard keyboard, one of them always opens first no matter which app you are in. On Oppo phones this order comes from a language list that most people never touch, so the wrong language keeps showing up before you even start typing. Switching manually every time gets old fast once you notice the list itself controls what appears first.
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.
Create Folders on Home Screen
Icons piling up on your Oppo home screen make it hard to spot the app you actually need. Dragging one icon onto another works, but it gets messy once you have more than two or three apps to group. This guide covers the dedicated folder function, which is faster when you want to sort several apps at once.
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.
Turn On Automatic Network Selection
If your Oppo phone stopped switching carriers on its own, someone likely turned off Auto select while picking a network manually. Without automatic selection enabled, the phone stays locked to one operator even when a stronger signal sits nearby. This mostly happens on Coloros devices where the toggle hides inside the SIM card settings rather than the main network menu.
Block a Phone Number from Call History
Getting repeat calls or texts from the same number on your Oppo phone and want them stopped for good? A quick way is to block that entry directly from your Call history, so future calls and messages from it get filtered out automatically. By default you still see a notification when a blocked number tries to reach you, which can throw people off if they expect it to go completely silent.
Expand RAM Using Internal Storage
If your Oppo phone slows down when you switch between several apps, the built-in RAM expansion feature might still be turned off. This function borrows free space from internal storage to act as extra RAM, but it only shows up if enough storage is free and your model supports it. Not every device offers the same expansion size, and the setting can be easy to miss in the menu.
Using the Stopwatch
If you want to time an activity or track individual laps on your Oppo phone, the stopwatch inside the Clock app handles both jobs at once. Many people only notice the lap counter after already tracking split times by hand, which makes the built-in option worth knowing.
Show Device Certification Info
If you need to confirm that your Oppo phone carries the right regulatory marks for your country, the certification numbers are not printed anywhere on the case. Retailers, customs offices or repair shops sometimes ask for proof of a CE, R-NZ or FCC-ID mark before accepting a return, import or warranty claim. That information sits inside a dedicated settings screen instead of the box or manual.
Set Up Access Point Names (APN) Manually
If mobile data won't connect or SMS and MMS refuse to send on your Oppo phone, a missing or incorrect access point is usually the cause. This happens after a SIM swap, a factory reset, or when the network profile never downloaded automatically. Entering the APN by hand fixes both data and messaging in one step.
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 Default Dialer App
If you have installed a second calling app on your Oppo phone, incoming calls might still open the wrong app or not ring through the app you actually want to use. This happens because ColorOS only routes calls through whichever app is set as the default phone app.
