Show Date and Location of Photos and Videos
Wondering exactly when a shot was taken or where you were standing at the time? OnePlus stores that data inside the file itself, but the Gallery thumbnail never shows it. Location tags only appear if geotagging was active in the camera app when the photo or video was captured.
Manage App Location Permissions
If an app keeps asking for your position or drains battery in the background, it likely still has broad location access on your OnePlus phone. OxygenOS lets you set that access per app, but the three permission levels are easy to mix up if you only skim the settings once. Getting this wrong either breaks features like maps or leaves GPS running when you never actually use the app.
Remove a Widget from the Home Screen
A widget on your OnePlus home screen can end up too big, too limited, or simply in the way once you have used it for a while. Since widgets do not sit in the app drawer, there is no simple uninstall option waiting for them there. If tapping or swiping on the widget itself has not worked so far, the removal gesture works differently from deleting an app icon.
Change Font Style
Stuck with whatever font style you picked when you first set up your OnePlus? Switching it later does not require a factory reset, but the option sits inside a settings area that is easy to overlook. OxygenOS ships with only two fonts, Roboto and OnePlus Slate, so the actual change takes seconds once you find the right menu.
Reset Advertising ID
If ads on your OnePlus phone keep referencing searches or apps you thought were forgotten, the advertising ID behind them is still doing its job. This identifier links your activity across apps so companies can keep refining the same profile of you. Resetting it breaks that link and forces every app to start building a fresh, anonymous profile.
Auto-Disconnect from Network at Data Limit
If mobile data suddenly stops working right after you cross your monthly allowance on a OnePlus phone, a built-in limiter is likely the cause, not a network outage. This goes beyond the usual data warning: OxygenOS can automatically kill every cellular data connection once the billing cycle limit is reached. Wi-Fi stays untouched, so calls and browsing over a home or office network keep running.
Merge Duplicate Contacts
If WhatsApp or another messenger keeps saving people you already have stored on your OnePlus, the same person often ends up listed twice. Calls, messages, and contact details then split across two separate entries instead of staying in one place, making the contacts list harder to search.
Force Stop an App
When an app on your OnePlus phone freezes, drains the battery in the background, or simply refuses to close, the usual back button and recent-apps swipe often do nothing. This happens when a process gets stuck in memory and stops responding to normal system commands. Force stopping kills the app directly through the system, though any unsaved data inside that app will be lost.
Rename a Paired Bluetooth Device
If you pair several Bluetooth devices with your OnePlus phone, the connection list quickly becomes confusing. Some earbuds, trackers or car kits only show up with a generic model code or their MAC address instead of a proper name. That makes it hard to tell which entry belongs to which device when you want to connect or disconnect something fast.
Enable or Disable Fixed Dialing Numbers
If your OnePlus phone suddenly blocks calls to numbers that are not on a specific list, Fixed Dialing Numbers (FDN) is probably active. This call restriction only allows contacts stored on the SIM card to be dialed, which many parents use to limit a child's phone to a few approved numbers. Turning FDN on or off always requires the PIN2 code from your carrier, not the regular SIM PIN.
Enable or Disable the Emoji Switch Key
Typing emojis on your OnePlus normally means holding down the language key or hunting through a separate emoji panel, which slows you down in chats and emails. A dedicated emoji key on Gboard puts the smiley picker one tap away, but it swaps places with the globe icon used to switch languages. If you type in more than one language, that trade-off matters before you turn the option on.
Enable or Disable Auto-Capitalization
If Gboard keeps switching the first letter of a word to uppercase right after a period or a new line, auto-capitalization is behind it. The feature reads sentence breaks and inserts a capital letter automatically, which speeds up everyday typing in WhatsApp or email but gets in the way when you write in lowercase on purpose, use slang, or paste code snippets. Switching it off leaves capitalization entirely in your hands.
Set Up a Proxy Server
If your OnePlus phone seems to have no proxy option at all, you are looking in the wrong place. The setting only shows up once you open the properties of a Wi-Fi network you are already connected to. Without a valid proxy host name and port, the connection will simply fail to save.
Show or Hide Birthday Reminders in Calendar
If your OnePlus calendar suddenly stops showing a contact's birthday, a Google Account setting is usually behind it. Every linked account carries its own birthday visibility toggle, so one account displaying dates does not mean all of them do. A birthday that was visible last month can quietly vanish once a second account gets added.
Enable or Disable Camera Grid Lines
If your landscape or panorama shots keep coming out crooked, the OnePlus camera has no visual reference for a straight horizon. The Grid overlay in the Camera app adds guide lines across the viewfinder, but the toggle for it sits a few taps deep in the settings. Without it turned on, lining up horizons or symmetrical compositions comes down to guesswork.
Change Ringtone Volume
If calls go unanswered because the ringer barely makes a sound, the ring volume on your OnePlus phone is likely turned down too far. This same volume level also controls notification tones for messages, WhatsApp alerts, and system sounds, so a quiet ringer often means quiet alerts everywhere else too.
Delete an Album in Gallery
Old collections pile up in the Gallery app and take up space you want back. Before you tap Delete on an album, it helps to know that removing it wipes every photo and video stored inside, not just the album itself. Mixing up 'delete album' with 'remove from collection' can cost you files you actually wanted to keep.
Clear Browser Cache in Chrome
If Chrome on your OnePlus keeps showing outdated versions of a page or feels sluggish when loading images, a bloated cache is usually the reason. The cache stores images and files from visited pages to speed up reloading, but over time it can grow large and take up storage. Clearing it forces Chrome to fetch fresh content on the next visit.
Apply Camera Filters
If your photos still look flat despite good lighting, the built-in camera filters on your OnePlus phone can add a distinct look before you even hit the shutter. The filter selection sits inside the Camera app but is easy to miss if you have not tapped into the filter menu before. Color, black and white and several stylized looks are all available without leaving the viewfinder.
Enable or Disable Spell Check
On a OnePlus phone, Gboard runs two separate features: auto-correction and spell check. If spell check is active, typos get underlined instead of fixed automatically, which can be confusing when you expect immediate corrections. Turning it off stops the underlining without touching auto-correction.
Enable or Disable Wi-Fi
If Wi-Fi on your OnePlus phone keeps dropping, reconnecting slowly, or refuses to join a network at all, switching the radio off and back on often clears the stuck state. This matters most before downloading larger files, apps, or updates, since a shaky Wi-Fi connection can stall or fail those transfers. Knowing exactly where the toggle sits also helps when you want to force the phone onto mobile data instead.
Delete a Contact
Old numbers, duplicate entries, or contacts you no longer need can pile up in the Contacts app on your OnePlus phone. Deleting a contact removes every stored detail at once, including phone numbers, addresses, website entries, and birthdays. If that contact is linked to your Google Account, the deletion carries over there as well.
Edit a Contact
A wrong phone number or an outdated email on a saved contact can cause you to call or message the wrong person. On a OnePlus phone you can correct, add, or remove any contact detail at any time, without creating a duplicate entry. It does not matter whether you are fixing a typo, adding a new field, or clearing out old information.
Set the Rear Camera Video Resolution
If video recordings fill up your OnePlus storage faster than expected, the active video resolution and frame rate are usually the cause. Higher resolutions and higher FPS values produce noticeably larger files per minute of footage. Checking the current setting helps you balance quality against free storage before you start recording.
