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 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.
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.
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.
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.
Factory Reset: Erase All Data
If your OnePlus phone keeps lagging, misbehaving after a failed update, or you are getting it ready to sell, a factory reset clears every trace of your data. Once triggered, it wipes your linked Google account, all system and app settings, and every installed app - permanently. Knowing what disappears before you confirm helps you avoid losing files you still need.
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.
Assign Alarm Functions to Volume Buttons
When an alarm rings on your OnePlus phone at night, the side volume buttons can control it instead of the screen. Some people want a quick snooze, others want the alarm to stop immediately with one press, and some prefer the buttons to do nothing so nobody silences the alarm by accident. If the wrong option is set, you might snooze an alarm you actually meant to turn off.
Record Screen as Video
Trying to capture a game session or a quick tutorial on your OnePlus, but you can't find a working screen recorder in the app drawer? The built-in Screen recorder tool sits inside the quick settings, not as a separate app, which is why many people miss it. Once it's running, a small floating control appears on screen, and tapping the wrong spot can stop the recording before you're done.
Change Lock Screen Wallpaper
If your lock screen still shows the default rotating daily image instead of your own photo, the wallpaper picker on OnePlus phones treats the lock screen and home screen as two separate slots. Many users only change the home screen and wonder why the lock screen keeps switching on its own. The fix sits inside the Customization menu, not the regular wallpaper shortcut.
Select Network Manually
Traveling abroad often means your OnePlus phone locks onto a foreign carrier with weak signal instead of a stronger one nearby. The automatic network search behind this behavior does not always pick the best available operator. Turning off automatic selection lets you choose a specific network yourself.
Install an App from the Google Play Store
Not sure whether the app you found online is safe to install on your OnePlus, or why the Install button in a store listing sometimes stays greyed out? The Google Play Store is the built-in source for messengers, games and system tools, but search results, region locks or missing sign-in can get in the way of a straightforward install.
Turn Off Instant Power Button Lock
If you tap the power button on your OnePlus even for a second, the screen locks right away and asks for your PIN, pattern or fingerprint again. That gets annoying when you only wanted to check the time or accidentally bumped the button. A setting inside the lock screen options controls whether the power button locks the phone instantly or with a short delay.
Pair a Bluetooth Device
If your OnePlus phone does not detect your headphones, speaker, or inEars, the accessory is often still in a locked pairing state or Bluetooth is switched off on the phone. Sometimes a short PIN prompt shows up during the connection and has to be confirmed on both sides before audio actually starts working.
Enable or Disable the Suggestion Strip
When typing a WhatsApp message or email on your OnePlus, Gboard normally shows a row of word suggestions above the keyboard based on what you have already typed. If that row is missing, cluttered, or keeps popping up when you do not want it, the Show suggestion strip option is likely set the wrong way. This affects how fast you can type and how much of the screen the keyboard takes up.
