Rearrange Quick Settings Icons
If your Quick settings panel feels cluttered or the toggle you reach for most sits on a second screen, the icon order on your Oppo probably still matches the factory layout. ColorOS lets you add, remove and reorder these buttons, but the edit mode is easy to overlook since it hides behind a small pencil icon in the panel itself. Between eight and sixteen icons fit here depending on your model, and a messy order slows down quick access to Wi-Fi, flashlight or Bluetooth.
Adjust Smart Sidebar Opacity
When the Smart Sidebar floating bar sits fully opaque on the edge of your screen, it can cover subtitles, icons, or app content behind it. On Coloros, the handle transparency is adjustable, so you can make it blend in during games or video playback instead of standing out. Left at the default level, many users find the handle too bold for everyday use.
Turn On/Off Automatic Data Sync
If contacts, calendar entries or photos on your Oppo phone stop updating in the background, the account sync toggle has likely been switched off. This setting controls whether signed-in accounts like Google keep pushing changes to your device without you opening each app manually.
Turn Fingerprint Animation Sound On or Off
Every time you unlock your Oppo phone with your fingerprint, a short confirmation sound plays. In quiet rooms or during meetings this beep can get annoying fast, and some users prefer silent authentication without an audible cue.
Open Eyes Requirement for Face Unlock
If Face Unlock keeps rejecting you even though you are staring straight at the screen, the open eyes requirement in ColorOS is often the cause. This check forces the camera to confirm both eyes are visibly open before it accepts a match. Glasses, sleepy eyes, or bad lighting can make this stricter mode fail more often than usual.
Change Always-On Display Clock Style
If your Oppo phone only shows the time and battery percentage on the Always-On Display, you are missing part of what the feature can actually do. ColorOS also lets you show the date and incoming notifications, but the toggle sits a few taps deep in the display settings and gets overlooked easily.
Copy Text From an SMS Message
Copying text from a text message on Oppo often fails because a short tap only opens the reply field or the keyboard instead of a selection menu. This makes it hard to grab a confirmation code, tracking number, or address to paste into another app.
SMS Delivery Reports: Turn On or Off
If you can never tell whether a text actually reached the other person, your Oppo phone probably has delivery confirmations switched off. The feature that sends you a status update once an SMS lands on the recipient's device sits inside the Messages app and is disabled out of the box. On dual SIM phones it also behaves differently depending on which SIM sent the text.
Archive a Conversation in Messages
When the Messages app on your Oppo phone gets flooded with old chats, the home screen turns into a scroll marathon just to find a recent conversation. Deleting isn't an option if you still need those messages later. Archiving hides a conversation from the main list without touching its content.
Set Default Account for New Contacts
Every time you add a new contact on your Oppo phone, ColorOS asks you to pick a storage account, and that gets annoying fast if you always choose the same one. Switching between your Google account and internal phone storage manually wastes time and can leave contacts scattered across different places. Setting a fixed default account for new contacts removes that extra tap for good.
Autospace After Punctuation Toggle
Typing fast on your Oppo phone and ending up with double spaces or missing spaces after periods and commas? Gboard's autospace feature inserts a space automatically after punctuation, which can clash with your own typing habits or with pasted text that already has spacing.
Schedule Always-on Display
If your Oppo phone runs the Always-on Display around the clock, it keeps drawing power even while you sleep or leave the phone in a drawer. ColorOS lets you limit the Always-on Display to a fixed time window instead of showing it non-stop. Without a schedule, the clock and notifications stay visible on the lock screen at every hour, day and night.
Add a Birthday to a Contact
Saving a contact's birthday on an Oppo phone looks like a small task, but many users expect ColorOS to send a reminder afterward. That does not happen automatically, and the date only sits inside the contact card until you check it yourself. Knowing where the birthday field actually lives saves you from digging through the wrong menus.
Change Keyboard Layout
Typing the wrong characters on your Oppo phone usually means the keyboard layout does not match the language you expect. German input calls for QWERTZ, English for QWERTY, and depending on the region you might need AZERTY, Dvorak, Neo2 or Colemak instead. Gboard on Coloros lets you add or switch these layouts per language, but the option sits several menus deep and is easy to miss.
Move Widgets on the Home Screen
A widget on your Oppo home screen sometimes ends up on the wrong page or crammed between app icons where it does not belong. A short tap just opens the widget or its app instead of letting you drag it. Knowing how long to hold before moving it keeps the widget from jumping back or landing in the wrong spot.
Turn Mobile Data On or Off
If apps stop loading anything once you leave Wi-Fi range on your Oppo phone, mobile data is probably switched off, or the wrong SIM is set for internet use on a dual-SIM device. ColorOS routes all cellular internet traffic through one single toggle, so a wrong access point can block traffic even when that toggle looks enabled. Checking the actual mobile data status first saves you from chasing the wrong problem.
Turn Super Power Saving Mode On or Off
When your Oppo phone is stuck at a low charge and you need it to last through the rest of the day, Super power saving mode cuts almost everything non-essential. It switches the display to dark mode, limits which apps can run in the background, and pauses syncing to squeeze out extra runtime. That trade-off means notifications, widgets, and most third-party apps stop behaving normally until you switch the mode off again.
Turn Do Not Disturb On or Off
If your Oppo phone stays completely silent even for important calls, or if it keeps buzzing when you actually need quiet, Do Not Disturb is likely misconfigured. The mode mutes sound and vibration system-wide and can hide notifications or let selected exceptions through, so getting the toggle and its options right matters. Many users only find the switch by accident because it sits inside the general sound settings rather than its own menu.
Allow or Block App Autostart
If your Oppo phone feels slow right after a restart, too many apps are probably launching in the background automatically. Each app that keeps an autostart permission keeps running silently, draining battery and RAM before you even open it. ColorOS has a dedicated manager for this, but it is easy to miss and even easier to leave misconfigured.
Send an MMS Message
If you attach a photo, video, or contact card to a text message on your Oppo phone, it stops being a plain SMS. The Messages app quietly converts it into an MMS, which can change how it sends, how big it can be, and whether your carrier bills it differently. Not realizing this switch happened is usually why an attachment seems stuck or never arrives.
Turn On/Off Screen-off Gestures
If double-tapping the display or drawing a quick O or V symbol does nothing while the screen is off, Screen-off gestures are probably disabled on your Oppo phone. These gestures let you open the camera, toggle the flashlight, or wake the display without pressing the power button. A single option in the convenience settings controls all of them.
Clear App Data to Reset an App
If an app on your Oppo phone keeps glitching, shows an outdated login, or wont sync even after a restart, clearing the cache alone often wont fix it. App data stores settings, saved files, login sessions and progress, so removing it resets the app to its original, freshly-installed state. That solves stubborn app bugs, but it also means everything the app saved locally is gone.
Add Contact to Home Screen
Calling a frequent contact on your Oppo phone often means opening the Phone app, tapping Contacts, and scrolling through the list every time. A home screen shortcut skips all of that and jumps straight to the contact's detail page, ready to call or message in one tap. Useful for family, work, or anyone you contact daily.
Mark a Contact as Favorite
Scrolling through a long contact list every time you need to reach the same few people gets tedious fast on an Oppo phone. Marking a contact as a favorite pins them to a quicker spot in Phone and Contacts, and favorites can also double as a group exception for Do Not Disturb or a whitelist against call blocking.
