Auto-Enable Power Saving Mode at a Set Battery Level
If your Oppo phone only switches to power saving mode after you tap it manually, the battery often drops further than you would like before you notice. Coloros can trigger power saving mode on its own once the battery reaches a level you choose, anywhere from 5 to 75 percent. Without this setting turned on, you have to remember to activate the mode yourself every time the charge gets low.
Show or Hide Birthdays in Calendar
Birthdays from your contacts do not always show up in the calendar app on an Oppo phone, even though the dates are stored correctly in your Google account. Usually the birthday calendar layer is just switched off or the sync has not caught up yet. This affects anyone who wants a quick overview of upcoming birthdays without opening the contacts app separately.
App Download Preference (Wi-Fi or Mobile Data)
New apps from the Google Play Store only download over Wi-Fi on your Oppo phone by default, and a large install can sit there waiting instead of finishing over mobile data. This is controlled by a setting inside the Play Store itself, not by Coloros. You can allow downloads over mobile data at any time, or set the Play Store to ask you every single time before it uses cellular data.
Add Emergency Information
If you collapse or end up in an accident, paramedics often can't unlock your phone to check your blood type, allergies, or medications. Oppo lets you store that medical profile so it shows up during an SOS call, no passcode needed. Without filling it in, first responders only see your name and photo, not the details that actually matter in an emergency.
Set Time Manually
If the clock on your Oppo phone refuses to change no matter what you tap, the phone is still pulling the time from the mobile network. As long as 'Use time from network' stays active, the manual time field is locked or simply not shown inside Date & time. Turning that toggle off is what unlocks the option to type in your own time.
Optimize Battery Consumption
If your Oppo phone drains fast even when you barely touch it, background apps are usually pulling power without you noticing. Oppo phones include a function that scans your usage and shows exactly how much charge you could save, app by app. Knowing which processes it restricts helps you decide if the automatic suggestion fits how you actually use your phone.
Reset Advertising ID
Ads on your Oppo phone keep matching your recent searches and app habits a little too closely. That happens because every device carries a fixed Advertising ID that links your behavior across apps for personalized ads. Turning off interest-based ads alone does not remove that link - the ID itself needs a reset.
Edit a Contact
When a phone number changes or a name is misspelled, the stored contact still shows the old details until you update it manually. This mix-up often causes calls or messages to go to the wrong entry, especially if the contact was synced from an old backup. Coloros lets you correct any field directly from the contact card without deleting and re-adding the entry.
Filter the Call History List
If your call history on Oppo mixes incoming, outgoing and missed calls together, spotting who you failed to reach gets tedious once the list grows. The phone app hides a filter that narrows the view down to just missed calls. Without it, you end up scrolling through every entry to find what you actually need.
Set Up Fingerprint Unlock
If your Oppo phone still asks for PIN, pattern or password every time you wake the screen, the fingerprint sensor probably is not set up yet. Fingerprint unlock only works once a backup method like PIN or pattern is already active, since ColorOS needs that fallback to register your print. The same fingerprint also works as a shortcut to reset a forgotten lock screen password.
Change Security Question for Privacy Password
If you cannot remember the answer to your privacy password security question, you lose the only way to reset a forgotten privacy password on your Oppo phone. ColorOS ties the entire recovery process to that single question and answer, so a weak or forgotten one leaves protected apps and files out of reach. Swapping in a question you will actually remember closes that gap before it becomes a problem.
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.
Add Trusted Places to Smart Lock
If your Oppo phone keeps asking for a PIN or pattern even at home or in the office, Smart Lock's Trusted Places feature is probably not configured yet. Without a saved location, the phone falls back to your regular screen lock everywhere, including places you visit every day. Trusted Places keeps the device unlocked within roughly 50 meters of a spot you pick, as long as location services stay on.
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.
Volume Buttons Function for Camera
On Oppo phones, pressing a volume button while the Camera app is open takes a photo instead of adjusting the sound level. This happens because Coloros assigns the buttons to shutter control by default, and the same option can be switched to zoom instead.
Turn Personalized Ads On or Off
Every Oppo phone carries a unique Advertising ID that networks use to build a profile from your app usage and browsing habits. If ads keep following you across unrelated apps with oddly specific products, that identifier is the reason. You can either reset this ID for a fresh start or opt out of ad personalization completely.
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 Call Vibration On or Off
Every incoming call makes your Oppo phone buzz, even when you already picked a ringtone you like. If that vibration feels distracting, unnecessary at your desk, or drains the battery faster during calls, the toggle for it lives inside your sound settings, not in a separate ringtone menu.
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.
Forward a Message on Oppo
Retyping a text just to send it to someone else wastes time, especially when the message contains links or details you cannot easily reproduce. Oppo phones let you forward an SMS straight from the conversation, and you can also send it to a different app instead of another contact.
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.
