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.
Send an MMS with Photos or Videos
Trying to send a photo or video through the Messages app but the message behaves differently than a normal text? On a OnePlus phone, attaching a file automatically turns the conversation into an MMS, which depends on mobile data instead of just signal. Group chats, file size limits and carrier settings can all affect whether the attachment actually goes through.
Change Long-Press Shutter Action
Holding down the shutter button in the OnePlus Camera app instantly starts a video recording instead of taking a photo. If you actually want a quick burst of shots when you press and hold, the camera is simply set to the wrong long-press action.
Audio Balance: Left/Right Adjustment
If one ear picks up sound noticeably louder than the other on your OnePlus phone, calls and media can feel unbalanced or tiring to listen to. This often happens with slight hearing differences between ears or with headphones that sit unevenly. OxygenOS lets you shift the output continuously toward one side instead of living with the imbalance.
Enable or Disable Adaptive Brightness
If your OnePlus screen keeps dimming or brightening on its own, adaptive brightness is likely reacting to the light around you instead of staying at the level you set. That can make the display feel too dark indoors or too bright at night, even after you adjust the slider manually. Switching this function off gives you full control again, while switching it on lets the phone handle brightness automatically.
Set Up Focus Mode
If certain apps keep pulling your attention away from work, muting each one manually gets old fast. Focus mode on your OnePlus phone pauses selected apps and hides their notifications for a set time, but it only works if you pick the right apps and turn it on the right way.
Clear Call History
If your OnePlus call log is cluttered with old missed, dialed and received calls, deleting each entry one by one takes forever. The Phone app has a built-in option to wipe the entire history at once instead of managing every single call log entry manually.
Enable or Disable Select to Speak
If you want screen text read aloud on your OnePlus phone, Select to Speak speaks any text you tap or highlight. Once turned on, a floating control button shows up in the navigation area with options for starting, pausing, or continuing playback. Turning the feature off again removes that button and stops the read-aloud function.
Sort Contacts by First or Last Name
If your contact list on your OnePlus phone looks randomly ordered, the sorting setting probably does not match how the names were originally saved. Some contacts get stored with the first name first, others with the last name first, which throws off the alphabetical order you expect. A single setting in the Contacts app controls whether the list sorts by first name or last name.
Remove a Contact from a Group
If you remove a member from a group or label in the OnePlus Contacts app, it can look like the contact vanishes from your phone entirely. Only the group assignment is affected, the contact itself stays untouched. This distinction matters if you sort contacts into groups for calls or messages and want to avoid losing saved numbers by mistake.
Set Up Daily Wallpaper for Home and Lock Screen
If your home screen and lock screen show the same picture every day, the Shot on OnePlus wallpaper collection is probably still set to a fixed image instead of updating on its own. OnePlus ships a built-in daily wallpaper option that swaps the background automatically, but it only works once it is switched on for the screen you want. Without checking the update source, it can also pull new images over mobile data without you noticing.
