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.
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 Notifications for a Single App
One chatty app keeps buzzing your OnePlus phone while every other app stays quiet, and muting the whole device feels like overkill. This usually comes down to a per-app notification toggle that also controls sound and vibration for that specific app. Turning it off does not affect any other installed app.
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.
Add a Keyboard Language
Typing in a second language on your OnePlus often triggers wrong autocorrect suggestions or an unfamiliar keyboard layout. This happens because Gboard only shows suggestions and characters for languages you have explicitly activated. Adding the missing language keyboard fixes both issues at once.
Restore Deleted Photos and Videos
When a photo or video disappears from your OnePlus Gallery, it usually is not gone for good right away. Oxygen OS moves deleted media into a Recently deleted folder first, and only clears it out automatically after a set number of days. If that window has already closed, the file is permanently removed and no longer recoverable through the Gallery app.
Add and Manage Personal Dictionary Words
When your OnePlus keyboard keeps autocorrecting a name, abbreviation or technical term into something else, the word simply is not part of its known vocabulary yet. This gets annoying fast with names, addresses or industry jargon you type often. Saving the word once, together with an optional shortcut, stops the keyboard from fighting you every time.
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.
Add a Birthday to a Contact
Birthdays entered on other phones or synced accounts do not always show up in a OnePlus contact card, especially when the Date field defaults to a different label like Anniversary. Without the correct field type, the birthday reminder never triggers in Calendar or the dialer app. This causes missed birthday notifications even though the date is technically saved somewhere in the contact.
Set a Timer in the Clock App
If the countdown in your OnePlus Clock app keeps running past the time you wanted, or the alert sound never fires, the Timer tab often gets mixed up with the Stopwatch. Both live in the same app but use separate controls for starting, pausing, and resetting. Getting the hours, minutes, and seconds right the first time avoids missed alerts during cooking, workouts, or work breaks.
Enable or Disable Magnification (Accessibility Zoom)
Small text and icons on your OnePlus can be tough to read, especially in apps that ignore your font size settings. The Magnification accessibility feature lets you zoom in with a triple-tap or a dedicated shortcut, but it stays off until you switch it on. If tapping the screen three times keeps zooming in by accident, the same setting is the cause.
Add Users from Lock Screen (Enable/Disable)
Anyone who picks up your locked OnePlus can still create a new user profile if 'Add users from lock screen' is turned on. That option sits inside the multi-user settings and lets someone add an account without ever unlocking your device first. Turning it off limits the lock screen to switching between profiles that already exist.
Lock Apps with an Extra Password
If anyone who picks up your unlocked OnePlus can open banking, messaging or gallery apps without any extra check, App locker is still switched off. OxygenOS can require your lock screen password or pattern again before those specific apps open. You can also decide whether notification previews from locked apps still show up on the lock screen.
Create a Folder on the Home Screen
When your OnePlus home screen fills up with icons, finding the right app takes longer every time. OxygenOS does not sort apps into categories automatically, so scattered icons for messaging, games, or tools quickly turn into visual clutter. Grouping related apps into a named folder keeps the layout manageable without deleting anything.
Enable or Disable Google Autofill Service
If login fields, payment details or addresses fill in on their own on your OnePlus, Autofill with Google is doing the work in the background. That is convenient, but it also means saved passwords and card numbers sit ready to insert wherever a matching field shows up. Some people want that speed, others prefer to enter sensitive data manually every time.
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.
Setting Up a Wi-Fi Hotspot with Custom Name and Password
If your OnePlus hotspot still shows the default device name or has no password at all, anyone nearby could spot it or try to connect. This happens because the personal hotspot feature activates with a generic name and no security until you set your own credentials. It does not matter whether you prefer letters, numbers, or a mix - the important part is setting it yourself.
