Turn Call Vibration On or Off
If your OnePlus phone buzzes every time someone calls even though you only want the ringtone, or the vibration stays off in a quiet room where you actually need it, the culprit is a separate vibration setting tied to Phone ringtone and vibration. Ringtone volume and vibration are controlled independently on OxygenOS, so muting one does not affect the other.
Enable or Disable TTY Mode
If a hearing or speech aid device cannot connect to calls on your OnePlus, TTY mode is probably switched off in the Phone app. Without it, the phone cannot convert voice to text or text to voice during a call, which makes standard calling unusable for TTY users. The setting sits in the accessibility options of the Phone app and is off by default.
Block Pop-ups and Redirects in Chrome
If tapping a link on your OnePlus phone keeps throwing you into random app stores or shady offer pages, Chrome's pop-up and redirect protection is probably turned off or has an exception saved for that site. This usually happens after accidentally tapping 'Allow' on a permission prompt or landing on a page with an ad-heavy redirect chain. Blocking these interruptions again only takes one setting inside Chrome's site permissions.
Enable Repeat Callers in Do Not Disturb Mode
If Do Not Disturb on your OnePlus phone stays silent even when someone calls back within minutes, the repeat callers option is likely switched off. This setting works independently from your allowed contacts or favourites list and only tracks how often the same number calls in a short window. Without it enabled, urgent follow-up calls get muted along with everything else.
Delete a Single Call History Entry
If you only want one call gone from your OnePlus call log, clearing the entire history is overkill and removes numbers you still need. A spam call, an accidental dial, or an old missed call can be removed on its own instead of wiping the whole list.
Add Contact to Favourites
Calling the same person over and over means scrolling through your whole contact list every time on your OnePlus phone. Marking that contact as a favourite pins it to the top of the Contacts app, so you skip the search entirely. It is a quick fix if you keep hunting for the same few names.
Set Up Parental Controls
Kids using a OnePlus phone can rack up screen time or download age-inappropriate apps from Google Play before you notice. OxygenOS hides parental restrictions inside Digital Wellbeing instead of a standalone app, so the option is easy to miss. Setting it up lets you limit device usage time and filter content without installing a separate parental app.
Reject Calls with a Quick Response Text
If your phone rings during a meeting or while you are driving, picking up is not always an option. On OnePlus phones you can decline the call and send a short text at the same moment, so the caller knows you saw it and will get back to them. The trick is finding the reply option before the call goes to voicemail.
Delete a Calendar Event
If an appointment in the OnePlus Calendar app keeps showing up after you moved it, or it's simply no longer needed, you can remove it for good. Recurring events add an extra step, since OxygenOS asks whether to remove just one occurrence or the whole series. Picking the wrong option here can wipe out dates you still needed.
Clear Browser History
If Chrome on your OnePlus keeps suggesting pages you visited weeks ago or autofill keeps offering addresses you would rather forget, your browsing history is still stored on the device. Over time this history also takes up storage space and can make the address bar feel cluttered.
Search a Conversation in Messages
Scrolling through months of texts to find one line is slow and often fails when you cannot remember which day the message came in. The built-in search inside a single conversation lets you jump straight to a keyword instead of scrolling through the whole thread.
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.
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.
Send an SMS Message
If you can't find where to start a new text or your message won't go through, you might be looking in the wrong app on your OnePlus phone. A plain SMS - no photos, no attachments - only works through the built-in Messages app and needs nothing more than a recipient and a typed text. Confusing this with a chat or RCS conversation is the most common reason people get stuck.
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.
