Double-Space Period Shortcut
Typing two spaces after a word sometimes inserts a period automatically, even when you only wanted extra spacing. This happens because the Gboard text correction feature turns a double space into a full stop at the end of a sentence. If the shortcut is missing or keeps triggering unwanted periods, the option needs to be checked directly in the keyboard settings.
Turn Screenshot Sound On or Off
Every screenshot on your Oppo phone plays a camera-shutter sound, even in meetings or quiet rooms. That noise comes from a dedicated toggle in the sound settings, not from the screenshot gesture itself, so silent mode alone often does not stop it.
Turn HDR On or Off in the Camera App
Photos taken indoors or against bright windows often come out either too dark in the shadows or completely blown out in the sky. That happens because the HDR mode in the Camera app is set the wrong way for the scene you are shooting. Switching it on or off manually gives you more control over exposure than letting the camera decide on its own.
App Animation Speed
If apps on your Oppo phone take a moment too long to open or the closing animation feels sluggish, the app animation speed is probably set slower than you like. This Coloros setting controls how quickly the transition plays when you launch or close an app, separate from actual app loading time.
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.
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.
Allow Calls During Do Not Disturb
If Do Not Disturb is active on your Oppo phone, calls get silenced unless you add an exception. You can choose to let calls through from everyone, only from saved contacts, or from a handful of selected people. Missing this setting means important calls go straight to silence with no ring at all.
Custom Notification Sounds per App
If every app on your Oppo phone plays the same generic notification tone, it gets hard to tell a chat message apart from a calendar reminder just by sound. Coloros lets you assign a separate ringtone to each app, but the option sits inside app management instead of the general sound settings. Many users only ever find the global tone switch and assume individual app sounds are not possible.
Turn Split Screen On or Off
If a three-finger swipe up does nothing on your Oppo phone, split screen mode might be switched off in the background. ColorOS ships with the feature active out of the box, but the gesture only works while split screen itself stays enabled in the settings.
Set Date Manually
If the date on your Oppo phone is wrong and there is no direct way to edit it, the automatic time sync is the reason. ColorOS locks date and time together, so both need attention once automatic sync gets switched off. Skipping the time step often leaves the clock inaccurate even after you set the correct date.
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.
Unlock Private Safe with Fingerprint
Typing in your privacy password every time you want to check files in Private Safe gets tedious fast. Oppo phones let you swap that PIN, pattern or password entry for a fingerprint tap, but the toggle sits buried inside biometric settings and stays off by default. Without switching it on, the fingerprint sensor you already use to unlock your phone has no effect on the vault.
Remove an App Shortcut from the Home Screen
If a shortcut icon refuses to disappear when you try to clean up your Oppo home screen, the App Drawer setting is usually the reason. With App Drawer enabled, removing a shortcut only deletes the icon, not the app. Without it, home screen icons and installed apps are the same thing, so removing one uninstalls the other.
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 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.
Delete Photos or Videos
Storage fills up fast when old photos and videos pile up in the Oppo Gallery app, and deleting them one by one feels endless. Switching to edit mode lets you select several files at once, but the items you remove do not disappear right away. They sit in the Trash for a while first, which still counts against your free storage until they are cleared out.
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.
Turn On or Off Video Subtitles
Videos with subtitle tracks often play without any captions showing up on an Oppo phone, because the subtitle option is switched off by default. If you rely on captions for language learning, noisy environments, or hearing support, this can make watching content frustrating until the right accessibility setting is found.
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/Off Call Barring
If certain calls still get through even though you set up barring, or international calls stay blocked after you land back home, the wrong barring option is probably still active on your Oppo. Call barring works per call type, so outgoing calls, outgoing international calls, roaming calls and incoming calls each have their own separate switch. On dual-SIM devices this gets confusing fast, since barring is configured per SIM card.
Turn High Performance Mode On or Off
If your Oppo phone drains battery fast or feels hot during gaming, High Performance Mode might already be active in the background. This setting disables every energy-saving feature to push maximum speed, which trades battery life and temperature for smoother performance.
Turn Glide Typing On or Off
Typing every letter by hand feels unnecessary when Gboard can turn a single finger swipe across the keyboard into a full word. On some Oppo phones, Glide typing stays switched off by default, so swipe gestures do nothing and the keyboard falls back to individual key taps. Whether you want faster input or need to stop an accidental swipe trigger, the setting sits hidden inside the keyboard 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.
Change Privacy Password
Switching from a PIN to a pattern for your Oppo privacy password, or just unsure which type you originally picked? The privacy password guards hidden files and cloned apps separately from your screen lock, so updating it means confirming the current one before you can set a new type.
