Make a Phone Call with the Phone App
If your OnePlus phone keeps asking which SIM card to call from every time you dial, or a call quietly goes out through the wrong number, the Phone app's Dual SIM handling is usually behind it. This mostly affects setups with two active SIM cards where no default line has been set for calls. Knowing where that selection lives saves you from mixed-up bills and missed callbacks.
Restore Archived Conversations in Messages
If a chat you need is missing from the main screen of the Messages app, it is likely sitting in the Archived folder instead of being deleted. Archiving hides a conversation from the start page without removing any messages, which often confuses users who think the thread is gone for good. You can still open and read an archived chat directly, but it will not show new message alerts on the home screen until you bring it back.
Switch Between Browser Tabs
Losing track of which tab holds the page you need makes comparing prices or reading several articles on your OnePlus browser annoying. The tab counter next to the address bar is easy to overlook, so you end up closing pages by accident instead of just switching to them.
Add a Keyboard Language
Typing in a second language on your OnePlus often triggers wrong autocorrect suggestions or an unfamiliar keyboard layout. This happens because Gboard only shows suggestions and characters for languages you have explicitly activated. Adding the missing language keyboard fixes both issues at once.
Archive Conversations in Messages
If your OnePlus inbox keeps filling up with chats you want to keep but don't need to see every day, archiving is the cleaner alternative to deleting. Archived conversations disappear from the main list but stay stored with every message and attachment intact. You can bring any of them back the moment you need the history again.
Turn Night Mode On or Off
Bright white light from the display can strain your eyes when you check your phone late at night or in a dark room. On OnePlus phones, Night mode shifts the screen to a warmer, beige-toned palette to cut that glare, but it is not always clear whether it runs on a schedule or only when switched on by hand. If the tint stays off after sunset or never fades back during the day, the schedule setting is usually the cause.
Filter Call History (All or Missed Calls)
Scrolling through a long call log to find one missed number wastes time on OnePlus phones. The Phone app mixes all call types together by default, so a missed call gets buried between outgoing and incoming entries. A quick filter switch narrows the list down to just what you need.
Restore Deleted Photos and Videos
When a photo or video disappears from your OnePlus Gallery, it usually is not gone for good right away. Oxygen OS moves deleted media into a Recently deleted folder first, and only clears it out automatically after a set number of days. If that window has already closed, the file is permanently removed and no longer recoverable through the Gallery app.
TalkBack Feedback Settings for Inputs
If TalkBack stays silent on some taps or buzzes too loudly during a call, the vibration, sound and audio ducking options are likely not tuned to your needs. OnePlus lets you fine-tune each feedback channel separately, including how much other audio gets muted while TalkBack speaks. Getting these settings wrong can make TalkBack hard to notice or disruptive during media playback.
Add and Manage Personal Dictionary Words
When your OnePlus keyboard keeps autocorrecting a name, abbreviation or technical term into something else, the word simply is not part of its known vocabulary yet. This gets annoying fast with names, addresses or industry jargon you type often. Saving the word once, together with an optional shortcut, stops the keyboard from fighting you every time.
Update a saved Wi-Fi password without reconnecting
If your router password changed, your OnePlus keeps trying the old credentials and drops the connection or refuses to join. Forgetting the network and setting it up again works, but it also wipes proxy settings, static IP entries, or metered data flags you configured earlier. Editing the saved entry directly keeps all of that intact.
Quick Search or All Apps in App Drawer
Swiping up on the OnePlus home screen sometimes opens a full grid of apps when you expected a search bar, or the reverse. This mismatch comes from a single toggle in the app drawer settings that decides what the swipe gesture actually triggers. Once you know where that switch lives, the gesture does exactly what you want every time.
Change the Start of the Week in the Calendar App
If your OnePlus Calendar always opens with Sunday as the first column, the app is likely following the week-start rule tied to your phone's region setting. That gets confusing when you travel for work and your team's calendar starts on Monday instead. Oxygenos lets you override this default and pick Saturday, Sunday or Monday as the start of the week.
Enable or Disable Mono Audio
If music or videos suddenly play through only one speaker with both channels squeezed together, Mono audio is likely active on your OnePlus. This accessibility setting merges the stereo channels so left and right output the identical signal. It helps with hearing loss in one ear, but it also removes stereo separation from calls, games and media playback.
Close All Browser Tabs at Once
If you spend a lot of time browsing on your OnePlus phone, the tab count in the Chrome app can quietly climb into the double digits. Closing each one individually wastes time and leaves the app running slower than it should. A single menu option clears every open tab in one go.
Flip to Silence for Incoming Calls
When a call rings loudly in a meeting and there is no time to dig for the phone, flipping it face-down should mute it instantly. On OnePlus phones running OxygenOS, Flip to Silence only works once the option is switched on in the Phone app; until then, flipping the device does nothing to the ringtone or vibration.
Answer an Incoming Call
When your OnePlus phone rings, the incoming call takes over the entire screen along with the ringtone and vibration. Saved contacts show their name next to the number, but the actual answer control is a sliding gesture rather than a simple tap. Tap the icon like a button and nothing happens, so the call keeps ringing until it drops to voicemail.
Enable or Disable Data Saver
If apps stop refreshing content in the background or photos in messaging apps only load after you tap them, Data Saver is likely active on your OnePlus. This mode limits background data usage per app once your mobile data connection kicks in, so updates and previews arrive later than usual. It can also delay push content in social or news apps until you open them directly.
Forward an SMS or MMS Message
Retyping or copying a text just to send it to someone else wastes time, especially with longer MMS content like photos or shared links. The Messages app on OnePlus phones has a built-in Forward option that gets skipped by many users because it hides inside a long-press menu. Without it, important information often gets lost in manual retyping or screenshots.
Set Dwell Timing for Mouse Click
If you connect a USB or Bluetooth mouse to your OnePlus phone, an automatic click can trigger as soon as the pointer stops moving. Depending on the delay you have set, this click may fire too quickly or take far too long, making menus feel unresponsive or overly sensitive. Dwell timing controls exactly how long the cursor has to stay still before that click happens.
Show Weather Details for a City in World Clock
World clock entries on your OnePlus show more than just the local time - each city also carries a small temperature reading next to it. That number alone does not tell you much, and it is not obvious how to see the fuller weather picture for a specific city.
Set a Timer in the Clock App
If the countdown in your OnePlus Clock app keeps running past the time you wanted, or the alert sound never fires, the Timer tab often gets mixed up with the Stopwatch. Both live in the same app but use separate controls for starting, pausing, and resetting. Getting the hours, minutes, and seconds right the first time avoids missed alerts during cooking, workouts, or work breaks.
Enable or Disable NFC
Contactless payment fails at checkout, or your OnePlus won't pair with a speaker or headphones by tap - in most cases NFC is simply switched off. Some users also want to disable NFC on purpose, either to save a bit of battery or to avoid accidental taps against payment terminals in a crowded bag. On several OxygenOS builds the toggle isn't in the quick panel at all, which is why people keep searching for it in the wrong place.
Change Device Name
If your OnePlus phone shows up with an unclear or generic label when you connect to Bluetooth speakers, a car system or your home Wi-Fi, that name comes from the device name setting. It has nothing to do with your phone number, email or OnePlus account, and other users on the same network can see it too. Swapping it for something you actually recognize makes pairing and file sharing far less confusing.
