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 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 Device Admin Apps
If a security or productivity app suddenly loses the ability to lock your screen, wipe data remotely, or enforce password rules, its Device admin app permission may have been switched off. On OnePlus phones this special access level controls how deep an app can reach into system settings and internal storage. Losing track of which apps hold this permission can leave the phone either over-exposed to a single app or missing features you actually rely on.
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.
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.
