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.
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.
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.
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.
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.
Turn Automatic App Updates On or Off
If your Oppo phone keeps downloading app updates over mobile data or storage fills up without warning, the Play Store's auto-update setting is likely active in the background. Depending on your preference, updates can be limited to WLAN, allowed over any connection, or switched off completely. Checking this setting also helps when apps update at random times without asking for confirmation first.
Reset System Settings
If your Oppo phone keeps using the wrong ringtone, an old wallpaper or a saved WiFi password that no longer connects, a full factory reset is overkill. Resetting the system settings only clears the device configuration itself, not your photos, apps or files. This distinction matters when you just want to fix a misconfigured setting without losing anything stored on the phone.
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.
Set a Data Limit for the Personal Hotspot
If your Oppo shares mobile data through the personal hotspot, other devices can burn through your plan without any warning. Without a fixed cap, laptops and tablets connected to the hotspot keep pulling data even after your allowance is gone. A data restriction shuts the hotspot down automatically once the defined limit is reached.
Set Default SIM Card for Calls
With two SIM cards active on your Oppo phone, the system decides on its own which SIM handles an outgoing call unless you set a fixed one. If calls keep going out on the wrong SIM, or ColorOS asks you every single time which line to use, the calling preference in your dual-SIM settings is the setting responsible.
Daily Mobile Data Limit Warning
If you expect your Oppo phone to cut off mobile data once you hit a daily limit, you might be surprised. On ColorOS, the daily limit setting only sends a warning notification between 10 MB and 100 GB, it does not block your connection. That distinction matters if you are trying to avoid overage charges before your billing cycle ends.
Uninstall an App via Settings
Long-pressing an app icon on your Oppo home screen and tapping Uninstall does not always work, especially if the shortcut sits inside a folder or has been removed from the home screen entirely. In that case the quick gesture method fails and you need a menu that lists every installed app regardless of where its icon lives. The App management section in Settings covers exactly that gap.
Delete a Single Text Message
When you want to remove just one text from a conversation on your Oppo phone, tapping and holding brings up a pop-up window, but it is easy to select the wrong option and delete the whole thread instead. This mix-up happens because the delete action behaves differently depending on whether you select one message or several at once. Clearing out old messages this way can also feel slow if you are trying to remove more than a handful.
Power Off the Oppo Phone
On Oppo phones running ColorOS, the shutdown screen looks different from stock Android. Instead of tapping a Power off switch, you get a slider you have to drag downward, and if you let go too soon, the phone just stays on and the screen goes back to normal.
Screen Color Temperature Settings
If your Oppo screen looks too blue or too yellow compared to other devices, a display calibration setting is shifting the white balance away from neutral. This often happens after enabling Eye comfort or Dark mode, which both nudge the color temperature warmer automatically. The result is icons, photos, and videos that look off compared to how they were designed.
Turn Emoji Suggestions On or Off in Gboard
If Gboard keeps popping up emoji suggestions while you type, or if none show up at all even though you want them, the Show emoji suggestions option in the text correction settings is likely set the wrong way. This behavior comes from the keyboard's input prediction feature, not from the messaging app itself. A quick check in the keyboard settings usually clears it up.
Connect via Wi-Fi Direct
If your Oppo phone will not show up when you try to send files to another phone, a TV stick or a smart appliance, Wi-Fi Direct is likely turned off or the target device is not currently visible. Both sides need the feature active and discoverable at the same time, otherwise the device list stays empty. This is different from a normal Wi-Fi network connection, which is why regular network settings will not fix it.
Rename a Fingerprint
On Oppo phones, every fingerprint you enroll gets a generic label like Finger 1 or Finger 2 by default. Once you have three or four fingers registered, telling them apart in the security settings becomes guesswork. Giving each entry a clear name fixes that confusion for good.
Change Camera Storage Location
If new photos on your Oppo phone keep filling up internal storage even though a memory card is inserted, the camera app is likely still set to save shots to the device only. This becomes a problem once internal storage runs low and you cannot move existing photos automatically. Switching the preferred save target inside the camera settings fixes this without touching your gallery app.
Turn Bluetooth On or Off
Bluetooth on an Oppo phone stays switched on out of the box, so it keeps scanning for nearby devices even when you never connect anything. That constant scanning quietly drains the battery, especially overnight or during long periods without any paired accessory.
Set Snooze Interval Time
Waking up too fast or too slow after hitting snooze on your Oppo phone? The default snooze length is fixed at 5 minutes, which feels too short if you want a real extra rest, or too long if you need to get moving fast. This gap between the snooze duration and your actual sleep needs is controlled in the Clock app settings, not in the alarm itself.
Schedule Eye Comfort (Blue Light Filter)
Switching Eye comfort on and off by hand every evening is easy to forget, and a missed night leaves blue light exposure disrupting your sleep. Oppo also lets the blue light filter run on a fixed schedule, but if the start and end times do not match your actual routine, the warm tint shows up too early or disappears before bedtime. Getting the schedule right on Coloros removes the need for daily toggling.
Factory Reset: Erase All Data
If your Oppo phone keeps freezing, lags after months of use, or you're about to sell or trade it in, a factory reset wipes every app, account, file and setting back to default. This removes personal data permanently, so backing up photos and documents beforehand matters. Only installed software updates stay untouched by the reset.
Change Home Screen Wallpaper
Tapping and holding the home screen only pulls up a handful of preset wallpapers on Coloros, so live wallpapers and your own photos are easy to miss. This happens because the quick wallpaper shortcut hides the full Wallpapers settings section, leaving many users thinking custom or animated backgrounds are not supported at all.
