Remove an Account on OnePlus
Old logins pile up in the account overview on your OnePlus phone and make it harder to spot the ones you actually use. Removing an account deletes its login credentials and any data that was synced through it, while the app it belongs to stays installed. This matters most for accounts like WhatsApp or Facebook, where contacts, messages, or cloud-synced content tied to that login disappear from the device once it's removed.
Enable or Disable Double-Click Power Button Camera Launch
If double-clicking the power button on your OnePlus keeps launching the camera by accident, or nothing happens when you try it, the Double click the power button setting is set to the wrong option. This shortcut works from the lock screen and while the phone is unlocked, and it also decides whether you can swipe in to check your latest photo or video right after taking it.
Call History Name Format Setting
If contacts in your call history show up as Last, First instead of First Last (or the other way around), it usually comes down to a display setting in the Phone app, not the contact entries themselves. This mix-up gets confusing fast when you are scanning recent calls for a specific person. The fix does not touch your saved contacts, only how names are displayed in the call list.
Screen Wake for Notifications
If your OnePlus screen stays completely black when a WhatsApp message or other notification arrives, you have to unlock the phone just to check who messaged you. This happens because the Ambient display option for new notifications is switched off by default on many devices.
Change Default Homepage in Chrome
If Chrome always opens to the same news feed with shortcuts and suggested articles when you launch it, the browser is using a preset homepage instead of a site you picked yourself. On OnePlus phones this default start page ships active out of the box and keeps loading until you override it. You can swap it for any web address you actually use every day.
Enable or Disable High Contrast Text
Small, thin fonts on a OnePlus display can be hard to read in bright light or with low vision. The High contrast text option in Accessibility settings widens text margins and sharpens edges for better legibility, but it stays off by default on most phones. If menus and app labels blend into the background, this setting is usually the missing piece.
Enable or Disable Mobile Hotspot
If your laptop or tablet cannot see your OnePlus phone's WiFi hotspot, or the connection keeps dropping, the toggle for it is not in the quick settings panel on OxygenOS. It sits inside the network menu together with the hotspot name and password. Leaving it on unnecessarily also drains the battery faster than a normal WiFi connection.
Allow App Installs from Unknown Sources
Trying to install an APK outside the Google Play Store and getting blocked on your OnePlus phone? Your browser or file manager needs explicit permission before it can install anything from outside the store. Without that permission enabled, Android refuses the installation as a security precaution.
Adjust screen brightness manually
If the screen on your OnePlus phone feels too dim indoors or too bright at night, automatic brightness is often making the call instead of you. Once Adaptive Brightness kicks in, the slider can jump around on its own, making it hard to lock in a comfortable level. Setting the brightness by hand gives you a fixed, predictable result every time.
Change Font Style
Stuck with whatever font style you picked when you first set up your OnePlus? Switching it later does not require a factory reset, but the option sits inside a settings area that is easy to overlook. OxygenOS ships with only two fonts, Roboto and OnePlus Slate, so the actual change takes seconds once you find the right menu.
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.
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 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.
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.
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.
Edit Quick Settings in the Status Bar
If your quick settings panel is cluttered with icons you barely use, or a toggle like Flashlight or Screen Recorder is nowhere to be found, the layout just needs a manual edit. OxygenOS keeps every extra shortcut hidden in a separate row until you drag it into the visible panel yourself. Until you sort that list, you keep swiping past icons you never touch while the ones you actually need stay out of reach.
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.
Change Alarm Volume
If your OnePlus phone barely wakes you up, the alarm might still be tied to your media volume level. OnePlus lets you adjust the alarm tone on its own scale with seven volume steps, independent of whatever you last set for music or games. That means a quiet media setting from the night before won't leave you oversleeping in the morning.
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 App Notification Dots
When WhatsApp, Messenger or another app gets a new message, OnePlus shows a small dot above the app icon by default, even after you have already checked the notification shade. This behavior comes from a single system toggle called Allow notification dots, not from the apps themselves. If the dots feel redundant or distracting next to your badge counts, you can switch the whole feature off in one step.
