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.
Set Dark or Light Theme for the Messages App
If the Messages app on your OnePlus phone still opens in a bright white layout at night, the built-in theme option is likely set to Light or System default instead of Dark. This app-level 'Choose theme' setting works independently from your phone's overall system theme, so changing one does not automatically change the other. Left on the wrong setting, this means unnecessary eye strain in dark rooms and slightly higher battery drain on an AMOLED screen.
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.
Pocket Mode: Enable or Disable
If your OnePlus phone keeps launching apps, dialing numbers, or waking the screen while it sits in your pocket, the built-in touch protection might be switched off. Pocket mode is meant to lock the display and fingerprint scanner whenever the phone detects it's stowed away, but the toggle can slip back to its default state after an update or reset. Here's what controls the behavior and how to check the current setting.
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.
Restart the Phone
If your OnePlus phone feels sluggish, apps stall in the background, or a fresh update refuses to finish installing, a restart usually clears the mess. Cache buildup and stuck background processes are the most common triggers. A quick restart resets these without touching your data.
Show or Hide Holidays in the Calendar App
If your OnePlus calendar shows a public holiday on almost every day, actual appointments get pushed down and easy to miss. This happens because the calendar app displays regional and national holidays by default, on top of every synced account. The more accounts you have connected, the more crowded the day view becomes.
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.
Sound & Vibration for Calendar Reminders
Missed calendar reminders on a OnePlus phone are often caused by a disabled sound or vibration setting inside the Calendar app itself, not by the phone's general ringtone. Without an active sound file or vibration pattern, alerts for appointments and events can pass by completely unnoticed.
Enable or Disable App Notification Dot
If a small dot keeps sitting on top of an app icon even after you already read the message or checked the missed call, the Allow notification dot setting is likely active for that app. OxygenOS adds this dot per app whenever a new notification arrives, and it stays visible until the notification is cleared or opened. Some apps show it constantly, which gets distracting if you only want the dot for apps that really need your attention.
Read in Background for Select to Speak
When Select to Speak is reading text aloud on your OnePlus phone, switching to another app usually stops the narration mid-sentence. The Read in background option keeps the voice going while you jump between apps, but it stays an experimental feature that can behave inconsistently. If speech cuts out unexpectedly or keeps running when you do not want it to, this setting is the reason.
Show Typing Indicators: Enable or Disable
If your chat partner keeps seeing you are typing even during short pauses, the Show typing indicators feature is broadcasting your input status. This works the same way as the typing bubble in WhatsApp, letting others know a reply is on the way. Turning it off removes that pressure without touching any other messaging setting.
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.
Enable or Disable JavaScript in Chrome
If buttons, menus or forms stop responding on a website you open on your OnePlus phone, JavaScript in Chrome may be switched off. Most modern sites rely on JavaScript for navigation, dynamic content and interactive elements, so turning it off can leave pages looking broken or unusable. You can check the current status and change it directly inside the Chrome app.
Choose Which Contacts Are Displayed
If your OnePlus phone shows every saved number in one giant list, work contacts and personal ones end up jumbled together. This happens because the Contacts app pulls entries from every linked account and group by default, with nothing filtered out. Sorting this out keeps the list focused on the people you actually need to see.
Adjust Display Scaling for Icons and Elements
If icons, buttons, and app elements feel cramped or oversized on your OnePlus, display scaling is usually the cause, not the font size. OxygenOS lets you shrink or enlarge on-screen elements independently from text, which changes how much content fits per screen. Get this wrong and menus can overflow or buttons become hard to tap.
Lock Apps with an Extra Password
If anyone who picks up your unlocked OnePlus can open banking, messaging or gallery apps without any extra check, App locker is still switched off. OxygenOS can require your lock screen password or pattern again before those specific apps open. You can also decide whether notification previews from locked apps still show up on the lock screen.
Create a Folder on the Home Screen
When your OnePlus home screen fills up with icons, finding the right app takes longer every time. OxygenOS does not sort apps into categories automatically, so scattered icons for messaging, games, or tools quickly turn into visual clutter. Grouping related apps into a named folder keeps the layout manageable without deleting anything.
Enable or Disable Google Autofill Service
If login fields, payment details or addresses fill in on their own on your OnePlus, Autofill with Google is doing the work in the background. That is convenient, but it also means saved passwords and card numbers sit ready to insert wherever a matching field shows up. Some people want that speed, others prefer to enter sensitive data manually every time.
Enable or Disable On-Body Detection
When On-body detection is active, your OnePlus phone stays unlocked the moment you pick it up or carry it in a bag, even after the screen would normally lock. The feature only checks for motion, not who is actually holding the device, so anyone carrying it gets the same access. If your phone keeps unlocking itself on the way to work or during a workout, this Smart Lock option is usually the reason.
Use Google Lens in the Camera App
If the camera viewfinder does not recognize landmarks, text or products on its own, Google Lens is probably still hidden inside the camera shortcuts. On OnePlus phones running Oxygenos, Lens sits as a separate option in the Camera app and only scans the frame once you tap it and pick a category.
Manage Individual App Permissions
If a OnePlus app suddenly can't reach your contacts, camera, or storage, a permission was likely denied at some point, either by you or automatically. Apps only ask for access like location or storage when they actually need it, and each prompt can be allowed or denied on the spot. Over time this leaves some apps running with limited access for reasons that are not obvious anymore.
