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 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.
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.
Add a City to World Clock
If the Clock app on your OnePlus phone only shows your own time zone, keeping track of a call with someone abroad turns into constant math. The World clock feature lets you pin extra cities with their live time and current weather, but the button to add or remove them hides behind an icon that is easy to miss. Once you know where to tap, managing your list of cities takes seconds.
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.
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.
Restrict Apps to Wi-Fi Only or Mobile Data
If Netflix, YouTube or another streaming app keeps eating through your mobile data plan even when you are near a router, it is likely still allowed to use mobile data in the background. OxygenOS lets you lock individual apps to Wi-Fi only, or the reverse, so they never touch your cellular connection again. This is separate from the general data saver toggle and works per app.
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.
Schedule Do Not Disturb Mode
Turning Do Not Disturb on and off by hand every night or before every meeting gets old fast, and it is easy to forget switching it back off, leaving missed calls and messages piling up. On OnePlus phones, the Do Not Disturb schedule inside Sounds & vibration can handle that timing for you, based on either a fixed time window or calendar events. Multiple schedules can run at once, each with its own days and hours.
Disable Gmail Event Sync in Calendar
Booking a flight or a restaurant table on your OnePlus phone can suddenly add an extra appointment to your Calendar app that you never created manually. This happens because Gmail automatically forwards detected reservations and bookings as calendar events for every linked Google account. If you only want your own manually added appointments to show up, that automatic sync needs to be turned off.
