Tap-to-Capture: Take Photos with a Single Screen Tap
Tapping the screen to frame a shot on your Oppo camera sometimes fires the shutter instead of just setting focus. That happens because Touch to take photo is switched on, so the camera snaps the picture the instant focus locks on the spot you tapped. If you only wanted to adjust focus, this can lead to blurry or mistimed shots.
Turn Color Correction On or Off
If reds and greens look almost identical on your Oppo display, or if certain interface elements blend together, a color vision difference such as Deuteranomaly, Protanomaly or Tritanomaly might be affecting how you read the screen. ColorOS includes a built-in correction tool that shifts on-screen colors to make these differences less noticeable, but it only works once the right mode is selected. Leaving it off or set to the wrong mode means icons, charts and notifications can stay hard to distinguish.
Change Lock Screen Wallpaper
If your lock screen keeps showing the same picture as your home screen, ColorOS is applying wallpaper changes to both screens by default. This happens with your own photos, standard wallpapers, and live wallpapers alike. You need to pick the target screen manually to keep the two separate.
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.
Turn Auto Brightness On or Off
If your screen keeps getting too dark in bright rooms or too bright at night, the light sensor behind Auto brightness might be misreading your surroundings. Auto brightness is supposed to save battery and reduce eye strain by adjusting the screen on its own, but a dirty sensor, a case covering it, or a stuck setting can throw that off. Once you know where the switch lives, fixing it takes seconds.
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.
Switch Between 12- and 24-Hour Time Format
If your Oppo phone shows the time in 24-hour format but you expect a 12-hour clock with AM and PM, that is the default ColorOS behavior, not a bug. Some apps and widgets even keep displaying 24-hour time after you change the system clock, which confuses a lot of users. The fix sits in the date and time settings, separate from the region or language options.
Change TalkBack Navigation Settings
Once TalkBack is active on your Oppo phone, a single tap no longer opens anything, it only selects the item under your finger. A double tap is needed to actually confirm an action, which feels broken if you expected normal touch behavior. TalkBack's navigation settings let you switch to gestures, key combinations or fingerprint sensor control instead of the default tap-and-confirm method.
Change Keyboard Height
If typing on your Oppo feels cramped or the keyboard eats up too much of the screen, the default Gboard height is usually the cause. Coloros keeps this sizing option tucked inside the keyboard app itself rather than the main display settings, so most people never find it. Seven presets are available, from Very Low up to Very High.
Set Up Wi-Fi Tethering as a Repeater
If a room in your home barely gets a signal from your router, your Oppo phone can share its existing WLAN connection with other devices as a repeater. Wi-Fi Tethering lets you set a custom network name and password, or you can just keep the default values and connect right away. This only works while your phone stays connected to the source WLAN itself.
Turn Banner Notifications On or Off Per App
If banner notifications keep popping up for apps you would rather have silent, or a chat app stopped showing previews at the top of the screen at all, the setting sits inside the individual app notification controls, not in a general notification menu. On Oppo phones running Coloros, banners can be switched off or back on separately for every single app, and in some apps even per notification category.
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.
Camera Quick Launch Gesture
If double-pressing a volume button doesn't open the camera from a locked screen, or the camera keeps launching by accident in your pocket, the Quick launch gesture setting controls that behavior. It runs on Oppo phones through ColorOS but pauses automatically while music or other audio is playing. Checking whether the toggle is active or off clears up most issues with the double-press shortcut.
Auto-Reconnect to a Wi-Fi Network
If your Oppo phone keeps hopping back onto a weak or blocked Wi-Fi network instead of switching to mobile data, the Automatically reconnect option is the reason. It is active by default for every saved network, which is convenient at home but annoying near a guest hotspot with a login page or poor signal. You can turn it off for one network only, without affecting the others.
Add Apps and Games to Game Space
If a game or app does not launch inside Game Space on your Oppo phone, it usually has not been added to the managed list yet. Without that step, the app starts as a normal application and misses out on performance tweaks, do-not-disturb, and other Game Space functions.
Change Default Messaging App
If Messenger or another chat app keeps hijacking your text messages, Coloros still only lets one app act as the default SMS handler at a time. Several installed apps can request that role, which is why replies to notifications sometimes open the wrong client. Oppo controls this behavior through a single setting in the app management area, separate from the messaging apps themselves.
Change Font Size
If text on your Oppo phone looks too small to read comfortably or too cramped when enlarged, ColorOS lets you adjust the font size on its own. Only the letters scale up or down, while icons, buttons and layout keep their original size, which can make some screens look unbalanced at the extreme settings.
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 On/Off Google Location History
If Google Location History stays enabled on your Oppo phone, almost every street, building and restaurant you pass gets logged with a timestamp. That data sits in your Google account, not only on the device, and keeps growing even while the screen is off. Many Oppo users only spot the tracking when they open their Google Maps timeline and see a full map of their week.
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.
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.
Turn Airplane Mode On or Off
If your Oppo phone will not connect to a network, WLAN, or Bluetooth device, Airplane mode might already be running in the background. Turning it on cuts mobile signal, WLAN, Bluetooth and NFC at once, which is useful on a plane but confusing when it happens by accident. Switching it off again does not restore every connection automatically, since only the settings you had active before get reloaded.
