Enable or Disable Lift to Wake
If your OnePlus screen keeps lighting up every time you pick up the phone or just shift it in your hand, the motion sensor behind 'Pick up your phone to show' is reacting too eagerly. That constant wake-up drains battery faster and can expose your lock screen notifications at moments you did not intend. The setting is meant to save you a tap when checking the time, but it often triggers from pocket movement or when passing the phone between hands.
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.
Show or Hide the Specs Watermark in Photos
Photos from your OnePlus camera sometimes carry a small text stamp in the lower left corner naming the device model and camera technology. If you want a clean image without that branding, or you want it back for sharing, the toggle sits inside the camera app itself. Not knowing where to look often means people just live with photos they did not choose the look of.
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.
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.
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.
Add Members to a Contacts Group
A label or group in the OnePlus Contacts app stays empty until you actually assign people to it. Many users create a group but then struggle to find where to add contacts afterward, especially when they want to select several people at once instead of adding them one by one.
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.
Open WiFi Network Notification
If your OnePlus keeps popping up alerts every time you walk past a coffee shop or airport hotspot, the open network notification is doing its job a little too well. This constant pinging gets old fast in busy public areas. You can control exactly when and if these alerts show up.
Enable or Disable Keyboard Auto-Correction
Typing a technical term, a name, or slang on your OnePlus and watching Gboard swap it for a completely different word is frustrating, especially in a WhatsApp chat or a work email you cannot easily edit after sending. Auto-correction speeds up typing for most people, but it also guesses wrong often enough to break sentences or change meaning. If wrong substitutions keep showing up, the fix sits in the keyboard's text correction settings.
View Call History for a Contact
Missing the full call log for one contact makes it hard to check how often you called, got called, or missed someone recently. On a OnePlus phone this history sits inside the contact's own call entry, not in a separate app or settings menu. Without opening the right screen you only see the last call, never the complete list of calls, dates and durations.
Enable or Disable Large Mouse Pointer
Connecting a mouse via USB or Bluetooth to your OnePlus phone often leaves the pointer too small to track on a touchscreen-sized display. This setting controls how large the cursor appears when you navigate with an external mouse instead of your finger.
Enable or Disable Smart Answer for Bluetooth
If your OnePlus phone keeps ringing on your Bluetooth headset instead of picking up calls on its own, the Smart Answer for Bluetooth feature is probably switched off. Some car kits and speaker systems only work smoothly when a call connects automatically, without you tapping a button. A wired headset or a different earphone mode can also leave this setting in the wrong state.
Print a PDF File via Wi-Fi
When a printer sits in the same room but a PDF still will not print from your OnePlus phone, the Wi-Fi printing feature usually is not activated correctly. Android needs to detect the printer on the same network before the print dialog shows any device to choose from. Without that connection, the option list stays empty even though everything looks fine at first glance.
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.
Remove a Fingerprint
If a fingerprint no longer unlocks your OnePlus reliably or a scan keeps failing at the payment screen, an old or damaged fingerprint entry is often the cause. Up to five fingerprint IDs can sit on one device, and a faulty one among them slows down every unlock attempt. Removing the wrong finger entirely also switches off fingerprint unlock and fingerprint payment if no other ID remains.
Enable or Disable Incognito Mode in Chrome
If a search on your OnePlus suddenly opens inside a dark grey browser tab with a small mask icon in the status bar, incognito mode is active in Chrome. Bookmarks, history and autofill data stop saving in that tab, which can be confusing if you expect your usual browsing setup to load. Knowing where this mode lives helps you switch it on for private searches or turn it off when regular browsing feels off.
Change Camera Mode
If the OnePlus camera keeps opening in the wrong mode, or you cannot find the switch between Photo, Video and Pro, the mode bar at the bottom of the viewfinder is easy to overlook. Many users only ever tap the shutter button and never realize the row of mode labels above it can be swiped or tapped directly. Knowing exactly where that bar sits saves time whenever you need to switch quickly between stills and video.
Hide Apps on Home Screen and in App Drawer
If an app keeps showing up on your home screen or inside the app drawer even though you never use it, the shortcut is simply set to visible in the launcher settings. This is common for pre-installed apps or tools you only open occasionally and do not want cluttering your layout. The fix works whether or not the App Drawer is switched on, since OxygenOS handles hidden shortcuts separately from the visible grid.
Change Keyboard Height
If you turned on the extra number row in Gboard, the keyboard on your OnePlus phone can suddenly take up a large chunk of the screen. That leaves less room to read messages while typing and can feel cramped on smaller displays. Gboard offers several height presets, from Extra-short up to Normal and beyond, so you can pick a size that matches your hand and screen.
Change Google Backup Account
If you have several Google Accounts added to your OnePlus phone, your backups can end up saved under the wrong one. That makes it hard to find contacts, app data, or settings later, especially after a reset or when setting up a new device. Switching which account handles Backup fixes where that data actually lands.
Enable Fingerprint Unlock
If you are still typing in your PIN or pattern every time you pick up your OnePlus phone, you are missing the fingerprint sensor built into most models. Fingerprint scanning lets the device recognize you instantly without a code, but it only works once a fingerprint has been enrolled in Security settings. Skipping this step also blocks fingerprint-based app locks and quick approvals for payments.
