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.
Auto Click After Pointer Stop On/Off
Connect an external mouse to your Oppo phone and a click sound triggers itself whenever you stop moving the cursor for a moment. This comes from the accessibility feature Click when pointer stops, which fires a click automatically once the pointer rests, even if you did not press any button.
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.
Check for Software Updates Manually
If your Oppo phone hasn't picked up a new ColorOS version yet, waiting for the automatic background check can take days. The system only looks for firmware at set intervals, so a pending patch or security fix might sit unnoticed for a while. Triggering the check yourself confirms right away whether a new update is actually available.
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.
Add Trusted Devices for Smart Lock
If your Oppo phone still asks for a PIN even though your smartwatch or Bluetooth headset is connected, Smart Lock likely does not have that device listed as trusted yet. Trusted devices keep the phone unlocked automatically as long as the Bluetooth connection to a paired accessory like a fitness tracker, car handsfree, or headphones stays active. Pairing alone is not enough - the accessory has to be added to the trusted list before automatic unlock kicks in.
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.
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.
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.
