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.
Enable Emojis in the Symbols Keyboard
When you switch to the symbols keyboard on your OnePlus, recently used emojis do not show up above the number row. This forces you to jump back to the emoji picker instead of tapping a quick suggestion. A single Gboard setting controls whether that emoji strip appears at all.
Share Contacts
Forwarding a phone number often means retyping every detail by hand, from address to birthday. OnePlus lets you send contact details straight from the Contacts app, but the sharing option sits inside a menu that is easy to miss if you have never used it before.
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.
Add More Exceptions to Do Not Disturb Mode
Do Not Disturb on your OnePlus phone mutes calls and messages by default, but alarms, media playback, and touch feedback often keep misbehaving anyway. If you want alarms to still go off, media sounds to stay audible, or touch sounds to work while everything else is silenced, the standard call and message exceptions will not help. Those extra behaviors sit in a separate exceptions list that needs to be turned on manually.
Enable or Disable Long Press for Symbols on the Keyboard
If letter keys on your OnePlus keyboard show no secondary symbol, you have to switch to the symbols layout every time you need a special character. Long press for symbols adds a small extra character to each key, letting you insert it by holding the key instead. This setting sits inside the keyboard app itself, not in the general display options, which is why many users miss it.
Add WiFi Network Manually
If your OnePlus phone does not show a WiFi network in the scan list, the router is usually broadcasting a hidden or non-visible SSID. Without the network name in the list, you cannot tap it and connect the usual way. Adding the network manually lets you connect once you have the exact SSID and password from the router.
Create an Album for Photos or Videos
When photos and videos from trips, screenshots, and app downloads all land in the same Gallery feed, finding a specific shot later gets tedious. OnePlus Gallery groups everything by date by default, with no automatic sorting by topic or event. Creating a named album under Collections lets you group related media manually, but the name you pick sticks unless you go back and edit it.
Add Bookmark Shortcut to Home Screen
Typing the same web address into Chrome every day gets old fast, especially for sites that do not have their own app. A bookmark saved only inside Chrome's bookmark list still needs several taps before the page loads. OxygenOS lets you turn any website into a home screen icon that opens directly, without a detour through the browser menu.
Show or Hide Battery Percentage in Status Bar
Guessing whether your OnePlus is at 20 percent or 60 percent from the battery icon alone is unreliable, especially once the icon outline gets thin. Without an exact number next to the icon, you only see a rough fill level in the status bar. That makes it hard to judge how much time you have left before a meeting or a long trip away from a charger.
Set Calendar Event Colors by Category
When appointments from different Google Accounts, birthdays, and personal events all appear in the same shade, the Calendar app on your OnePlus gets hard to scan at a glance. Each event category can carry its own color, but the option sits inside the calendar settings and is easy to miss. Without it, a work meeting and a birthday reminder look identical in your day view.
Delete a contact group or label
A label with dozens of contacts you no longer need clutters the group list in the Contacts app, but removing every member one by one feels pointless. Deleting the group itself takes seconds and does not touch the contacts stored on your OnePlus phone. Only the grouping disappears, not the people in it.
