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.
Delete a Single Text Message
Sometimes only one message in a long thread needs to disappear, not the entire conversation. On a OnePlus phone, the standard option to clear a whole chat removes far more than you actually want to get rid of. Deleting a single message only changes what you see on your own device, so the other person keeps their copy of it.
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.
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.
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.
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.
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.
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 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.
Enable or Disable Find My Device
If your OnePlus goes missing and Google's Find My Device page marks it as offline, the tracking feature is probably switched off in your security settings. Without it active, you can't locate, ring, lock, or erase the phone remotely from a browser or another device.
Enable or Disable Data Roaming
Landing abroad with data roaming still switched off leaves your OnePlus without maps, messages or mobile data until you find a WiFi network. Roaming lets your phone connect through a partner network in another country, but this toggle usually ships turned off to avoid surprise charges. Leaving it on for the whole trip without checking your provider's roaming plan can also lead to a higher-than-expected bill.
Remove a Home Screen Folder
If a folder keeps sitting on your OnePlus home screen even though you barely use it, there is no direct delete option in OxygenOS. Folders only disappear once every app inside has been moved back out, which trips up a lot of people who expect a simple long-press delete button.
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.
Enable or Disable Touch Sounds
Every tap on a menu item or navigation key triggers a short tone on your OnePlus phone, and that constant clicking can get annoying fast in quiet rooms or during calls. The sound comes from a system setting for touch feedback that most people never touch after setup.
Resize a Widget
Some widgets on your OnePlus home screen refuse to shrink past a certain point, while others leave awkward empty space you cannot fill. The resize behavior depends entirely on how the widget was built, and not every widget supports free scaling. Knowing which widgets are flexible saves you from rearranging your whole home screen for nothing.
Touch & Hold Delay
If a long-press on an app icon or list item pops up its context menu too quickly, or feels sluggish before it reacts, the touch and hold delay on your OnePlus is set to the wrong value for how you actually tap. This timing decides how long you must keep pressing before OxygenOS treats it as a hold instead of a normal tap. A mismatched delay leads to accidental menus opening or a noticeable lag before options show up.
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.
Swap Navigation Button Order
On a OnePlus phone using the classic navigation bar, the Back button always sits on the left and Recent Apps on the right. If your muscle memory expects the mirrored layout, or you switched from a phone with the opposite order, you keep tapping the wrong key. A single 'Swap buttons' toggle controls this order, but it hides inside the buttons and gestures settings.
Enable or Disable Location (GPS)
If regional weather widgets show the wrong city or navigation apps cannot find your position, Location access on your OnePlus phone might be turned off. Location runs by default to support GPS-based features, but constant background tracking also drains the battery faster than expected. You can check the current status and switch it directly from the quick settings panel or the main settings menu.
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.
