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.
Add an App Shortcut to the Home Screen
When the app drawer is turned on, your home screen stays mostly empty and every app only shows up in the full overview list. That means an extra swipe and tap each time you want to open something you use daily. Adding a direct shortcut fixes that without switching off the drawer.
Enable or Disable Google Voice Typing
If dictation stays greyed out on your OnePlus keyboard or the microphone icon simply refuses to appear, Google voice typing is likely switched off in your keyboard settings. The feature converts spoken words into text for messages, emails and notes, but it only works once it is active for your virtual keyboard. A locked device after a restart can also block access until you unlock it first.
Disable Screen Animations
If your OnePlus feels sluggish when switching apps or opening menus, fade-in effects and shadows are often the cause. These transition animations use extra graphics processing and RAM every time a window or panel appears. Turning them off frees up resources without changing anything else about how your phone behaves.
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.
Power Button: Choose Power Menu or Voice Assistant
On many OnePlus phones, holding the power button on the side launches Google Assistant instead of the shutdown menu. That makes it awkward when you actually want to restart, power off, or trigger emergency mode. The behavior comes from a setting most people never touch after setup.
Change Notification Sound
If the same notification tone keeps going off for every text, WhatsApp message or app alert on your OnePlus phone, it is easy to start tuning it out. OxygenOS comes with a handful of preset tones, and you can add your own audio files once those feel repetitive. The setting that controls this sits a few taps deep in the sound options, which is why many people never change it.
Enable or Disable Color Inversion
When every color on your OnePlus screen suddenly looks reversed, like a photo negative, the Color inversion accessibility feature is usually the cause. This setting flips light and dark tones across the whole display, including photos, videos and app icons. It can be switched on by accident through a shortcut or left active after testing accessibility options.
Allow or Deny System Settings Permission
Some apps on your OnePlus phone ask to change system settings on their own, like the wallpaper or ringtone. This permission only covers those convenience settings and has no effect on security features such as the screen lock.
Optimize App Battery Usage
If a specific app keeps draining your battery in the background even when you are not using it, OxygenOS might not be limiting its power use the way you expect. Each app on your OnePlus phone has its own battery optimization setting, and the wrong choice here causes either faster battery drain or delayed notifications.
Switch Keyboard Language While Typing
Typing a message that mixes two languages and the keyboard keeps autocorrecting the wrong one gets annoying fast on a OnePlus phone. Most keyboards let you swap languages mid-sentence, but the trigger for that switch is not always obvious. Some people tap a small globe icon near the space bar, others just hold the space bar down and get nothing.
Change App Icon Shape and Style
If every app icon on your OnePlus home screen still looks like a plain square or circle, the icon shape setting is likely still on the default option. Switching between the pre-installed icon packs or a downloaded one changes the outline of every app symbol at once, but the option is easy to miss inside the home screen settings. Some downloaded packs also only apply partially if a step gets skipped.
Switch Between User Accounts
If several people share the same OnePlus phone, jumping into full system settings just to swap accounts feels slow. Each user profile keeps its own apps, wallpaper and data separate, so picking the wrong one mid-task can mean losing your open apps or notifications. The switch actually lives in the quick settings, not buried in a settings menu.
Change Calendar View
By default, the Calendar app on OnePlus phones opens with a combined overview of every added account, which makes it hard to see a full month at a glance. If you only need a quick daily rundown or a compact weekly plan instead, the current view setting is working against you. This applies to all accounts synced into the app, not just one calendar.
Change Default Messaging App
If your OnePlus keeps opening the stock Messages app instead of the messenger you actually installed, the phone is still pointing to the old default handler. Notifications, quick replies and even the share sheet stay tied to whichever app holds that role, no matter which one you prefer to type in. Switching the default only takes a moment, but the option sits a few menus deep in the system settings.
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.
Set the Time Manually
If your OnePlus phone keeps snapping back to the wrong time or a different time zone, the network time sync is overriding whatever you type in. Oxygenos pulls this value directly from your carrier, so a manual change gets reverted within seconds unless that source is switched off first.
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.
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 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.
Switch Between Gesture and Button Navigation
If the Back, Home and Recents bar keeps eating into your screen, or your OnePlus suddenly swipes instead of using buttons after an update, the navigation mode setting is behind it. OnePlus offers both classic button navigation and gesture navigation, and many people only notice the option once they want a cleaner screen or accidentally trigger the wrong mode. Picking the right one changes how you go back, go home and switch apps on every screen.
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.
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.
