Turn Do Not Disturb On or Off
Calls keep ringing through even though you switched on silent mode, or notifications stay muted long after you meant to turn them back on. On OnePlus phones, Do Not Disturb handles sounds, vibrations and call rejection separately from the regular ringer switch, so toggling one does not always affect the other. Knowing where this setting actually lives in Oxygenos prevents missed alerts or unwanted interruptions.
Set Up Bedtime Mode
If your OnePlus screen stays in full color and notifications keep buzzing right before you fall asleep, the built-in bedtime routine probably isn't active yet. Without a schedule, the phone never dims its colors or silences alerts on its own, so late-night scrolling gets no visual cue to stop. Bedtime mode ties grayscale and silence to a fixed time window or to your charging habit, so it works without you touching a single toggle each night.
Add a Contact Shortcut to the Home Screen
Digging through the Contacts app every time you want to reach the same person wastes time, especially if that contact is not one of your recent calls. On OnePlus phones, a home screen shortcut places that contact right next to your apps, one tap away. Here is what the Add to Home screen option actually does and when it is worth setting up.
Stop Battery Saver Turning Off After Charging
If Battery Saver on your OnePlus phone switches off by itself once charging passes roughly 90%, the „Turn off when fully charged“ option is behind it. That's inconvenient if you want power saving to stay active no matter how full the battery is.
Silence Alarms After a Set Time
If your OnePlus alarm keeps blaring long after you have already woken up, it can disturb the rest of the household or even the neighbors through thin walls. The Clock app lets you set a fixed duration after which the alarm stops on its own instead of ringing indefinitely. Without this limit, an unattended alarm just keeps sounding until someone dismisses it by hand.
Enable or Disable a SIM Card
On a Dual SIM OnePlus phone, one line sometimes needs to be shut off completely instead of just switched to the background. Turning off a SIM card stops it from receiving calls and texts right away, while mobile data and messaging priorities move automatically to the remaining card. This is useful when a second line sits unused for a while but should not be removed from the tray.
Add App to Data Saver Exception List
When Data Saver is active on your OnePlus phone, background data gets blocked for most apps. WhatsApp and other messengers can then miss incoming messages until you open them manually. Adding an app to the unrestricted data list keeps it connected even while data saving stays on.
Record a Video with the Camera App
Switching from photo to video mode on your OnePlus camera looks simple, but many people miss the pause control that sits right next to the shutter button once recording starts. Without knowing where it is, you risk stopping a clip too early or losing a moment you cannot repeat. The video toolbar behaves differently from photo mode, and that catches people off guard.
Enable or Disable USB Tethering
If your laptop or PC shows no internet connection after plugging in the USB cable, USB tethering on your OnePlus is probably still switched off or fighting with another active connection. Some OxygenOS versions also pop up a prompt asking which network connection to share, and picking the wrong one leaves the computer offline. This is different from a broken cable or driver issue, since the phone controls the tethering toggle itself.
Add a Printer Manually by IP Address
If your OnePlus phone does not detect your printer automatically, the built-in Default Print Service probably does not recognize your model. This happens with older or less common printers that are not listed in the supported device catalog. You can still connect the printer over your local network by entering its IP address directly.
Turn Off Wi-Fi Hotspot Automatically
If your OnePlus hotspot stays on for hours after everyone has disconnected, it keeps draining battery for no reason. This happens when the automatic shutoff for the Wi-Fi hotspot has been switched off or was never turned on. The setting only kicks in once no device has been connected for a few minutes.
Enable or Disable Screen Rotation
When you tilt your OnePlus sideways, the whole screen content flips with it, which helps when you are browsing a website or watching a video in landscape. The same behavior gets in the way when a photo, a game, or a fixed app layout rotates on its own at the wrong moment. If Auto-rotate keeps flipping your display unexpectedly, or refuses to rotate when you actually want it to, the setting controlling this behavior lives in the display options.
Enable or Disable Location Data in Photos and Videos
If your photos and videos do not show where they were taken in the gallery app, the camera is not tagging them with location data. This can happen after a system update or a fresh camera app install, when location tagging quietly resets to off. Turning geotagging back on lets you see the exact spot of every shot later, which is useful for travel photos or documenting a job site.
Enable Parallel Apps for Dual Messenger Accounts
Running two WhatsApp, Messenger, Facebook or Instagram accounts on one OnePlus phone usually fails because the app only supports a single login at a time. OxygenOS solves this with a built-in cloning feature that creates a separate, independent copy of the app. Without it, you are stuck switching accounts manually every time you need the other profile.
Assign a Custom Ringtone to a Contact
When your phone rings, you often can't tell who's calling until you glance at the screen. OnePlus lets you assign a distinct ringtone to individual contacts, including your own MP3 files, so specific callers stand out just by the sound.
Import Contacts from SIM or VCF File
Contacts stored only on a SIM card or in a .vcf backup file stay invisible to your OnePlus phone until you actively pull them into the Contacts app. That gap shows up right after switching SIM cards or setting up a new phone, when calls and messages suddenly miss names you know exist. Where you save the imported data - device storage or your Google account - also decides whether those contacts survive a factory reset or a phone swap.
Remove the Google Search Bar from the Home Screen
After setting up a OnePlus phone, the Google search bar sits fixed at the top of the home screen and takes up space you might want for apps or widgets. It behaves like a widget rather than a system element, so it can be taken off without touching any search functions on the phone. If it keeps coming back after a restart, a launcher setting is usually the reason.
Change Default Apps
If tapping a link or asking for voice assistance keeps opening the wrong app on your OnePlus phone, a default app assignment is pinned to a tool you no longer want. This happens after installing a new browser, messaging app or voice assistant that never took over the role automatically. The system keeps using the old default until you switch it manually.
Show Device Certification Labels
Looking for the FCC ID or HAC rating on your OnePlus phone but cannot find a physical sticker anywhere on the device? OnePlus stores these regulatory certifications digitally instead of printing them on the back cover. Which labels appear depends on your exact device model and sales region.
Edit Quick Responses in the Phone App
Rejecting a call with a text reply on your OnePlus phone often sends a generic message like 'I will call you back later' that does not fit the situation. The Phone app stores a fixed set of quick responses that rarely match how you actually communicate. Until you edit them, every caller you decline gets the same default text.
Rename SIM Card
When both SIM slots run cards from the same mobile carrier, the phone shows an identical label for each and calls or data usage become hard to tell apart. OxygenOS displays this carrier name by default instead of a custom label. Renaming each SIM card fixes the mix-up without needing to swap slots or restart the phone.
Delete Access Point Name (APN)
A wrong or outdated APN entry on your OnePlus phone can block mobile data or MMS even though your SIM card works fine elsewhere. This often happens after switching providers, since the old carrier's APN stays saved and OxygenOS keeps using it by default. Removing the leftover entry clears the conflict without touching your other network settings.
Add a New Home Screen Page
When every app and folder sits crammed onto one home screen, finding a single icon turns into a scroll-and-squint exercise. OnePlus phones let you spread apps across separate pages instead of piling everything onto one screen. This helps when you want a dedicated page just for messaging apps, games, or work tools.
Show Detailed Battery Usage
If your OnePlus battery screen only lists a few apps since you unplugged the charger, you are not seeing the full picture of what drained your battery. Oxygen OS keeps a more detailed breakdown that covers every app and background process since your last full charge, but it is tucked away from the main battery screen.
