Enable One-Handed Keyboard Mode
When you hold your OnePlus with just one hand, the Gboard keyboard often stays too wide for your thumb to reach the far edge. Typing single-handed then means stretching your thumb or shifting your grip with every message. One-handed mode shrinks the keyboard and pins it to whichever side fits your hand.
Remove a Keyboard Language
If your OnePlus keyboard shows too many languages and switching between them gets confusing, you can drop the ones you no longer type in. Extra layouts pile up in Gboard's language list over time and clutter the keyboard switcher, making it harder to find the language you actually use.
Enable or Disable Screen Cast
If your OnePlus phone won't show up when you try to mirror the display to a smart TV, monitor or Fire TV Stick, the Screen cast function is often switched off or blocked by a network mismatch. Wireless mirroring only works when both devices sit on the same Wi-Fi network, so a hidden toggle or a wrong network can quietly break the connection. Some OnePlus units also link this feature to a separate casting toggle, which adds another spot where it can get disabled.
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.
Camera Shutter Sound: Enable or Disable
A loud shutter click every time you snap a photo can draw unwanted attention in quiet places like meetings, libraries or classrooms. On OnePlus phones this sound comes from a setting inside the camera app itself, not from the general system volume. Many users search through the wrong menus before realizing the toggle sits right in the camera settings.
Enable or Disable Automatic App Updates
If apps on your OnePlus suddenly update over mobile data and eat into your plan, the Play Store is set to update apps over any network. The opposite problem also happens: outdated apps stay unpatched for weeks because updates are switched off entirely. Both behaviors trace back to one setting inside the Play Store, not the OnePlus system settings.
Delete a User Account
When a family member or guest no longer needs access to your OnePlus phone, their user account still sits in the multi-user list with all its apps and data intact. Leaving unused accounts active wastes storage and can expose personal content to anyone who switches profiles. Removing the account permanently wipes everything tied to it, so only the owner or an administrator should trigger the deletion.
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.
Set Default Account for New Contacts
If your OnePlus phone keeps asking which account to use every time you save a new contact, that prompt comes from having no default account set for new contacts. This gets especially annoying when you juggle a Google account alongside a local phone or SIM storage. Setting one fixed default account stops the repeated pop-up and keeps every new entry in the same place.
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.
Enable or Disable Android Beam
If Android Beam is missing from your settings, NFC is probably switched off on your OnePlus phone, since Beam only shows up once near field communication is active. Android Beam lets you send photos, contacts, or app content to another Android device just by holding the two phones back to back. Without it enabled you lose that quick tap-to-share transfer option entirely.
Special App Access Settings
Some apps on your OnePlus phone quietly ask for advanced permissions, like changing system settings, running in the background, or displaying over other apps. When an app behaves oddly or you spot an unfamiliar permission request, the special app access list shows exactly which app holds which of these rights. From there you decide whether to keep an access active or withdraw it.
