Enable or Disable Spam Protection in Messages
If the Messages app on your OnePlus keeps flagging normal texts as junk, or unwanted spam keeps slipping through unfiltered, the built-in spam protection setting is worth checking. This feature scans incoming messages and reports rough details to Google, without sending your phone number or the message content itself. You can switch it on or off depending on how much filtering you actually want.
Enable or Disable the Keyboard Number Row
If every digit forces a switch to the symbol keyboard, typing passwords or addresses on a OnePlus phone slows down fast. Gboard can add a dedicated number row along the top edge, but it takes up extra vertical space and some users prefer to turn it off again. Whether that row is active or hidden depends on a single Gboard preference.
Change Time Zone and Region Manually
If your OnePlus phone shows the wrong time or date after traveling, the automatic time zone detection is likely still pulling data from your carrier network. This happens because the network-based time zone setting stays active by default, overriding any manual change you try to make. You need to turn that function off before you can pick your own region and time zone.
Select Network Manually
Traveling abroad often means your OnePlus phone locks onto a foreign carrier with weak signal instead of a stronger one nearby. The automatic network search behind this behavior does not always pick the best available operator. Turning off automatic selection lets you choose a specific network yourself.
Add apps to a home screen folder
A cluttered home screen with dozens of loose app icons makes it hard to find anything fast. On OnePlus phones, apps do not merge into folders automatically, so you have to drag them in manually or they just sit scattered across your screens.
Connect to a Wi-Fi Network
Your OnePlus phone only auto-connects to the Wi-Fi network you set up on day one. Moving to a new home, joining an office network or logging into a guest hotspot means finding and adding that network yourself, and a mistyped password is the most common reason the attempt fails.
Turn On Wi-Fi Automatically
If your OnePlus keeps ignoring a known Wi-Fi network after you leave Bluetooth or mobile data active, the automatic Wi-Fi feature might be switched off. This function is supposed to re-enable Wi-Fi on its own once you are back in range of a saved network with a strong signal. Some people want the opposite and switch it off to stop the phone waking Wi-Fi unexpectedly and draining battery.
Enable or Disable Chat Features in Messages
If your OnePlus keeps showing typing indicators, read receipts or high-resolution photo sharing inside the stock Messages app, chat features are switched on and syncing over mobile data or Wi-Fi. Some users want this messenger-style behavior turned off because it reveals when a message was read or drains data in the background. Others find messages stuck on plain SMS because the toggle never got activated in the first place.
Pair a Bluetooth Device
If your OnePlus phone does not detect your headphones, speaker, or inEars, the accessory is often still in a locked pairing state or Bluetooth is switched off on the phone. Sometimes a short PIN prompt shows up during the connection and has to be confirmed on both sides before audio actually starts working.
Show or Hide Password Characters While Typing
On a OnePlus phone, each character you type into a password field flashes briefly before turning into an asterisk. That short preview lets anyone glancing at your screen catch a glimpse of your login details, which becomes a problem in public places or shared spaces.
Schedule Power On/Off
If your OnePlus phone keeps lighting up with notifications at night or drains its battery while you sleep, manually switching it off and back on every day gets old fast. The Scheduled power on/off feature lets the phone shut down and restart on its own at fixed times. Without it, you either leave the phone running all night or risk forgetting to turn it back on before your alarm.
Add another fingerprint
If your OnePlus phone only unlocks reliably with one specific finger, switching hands or holding the phone at an angle often causes failed scans at the lock screen. Oxygen OS lets you store several fingerprint IDs at once, not just the first one you registered during setup. That only helps once additional fingers are actually added and named so you can tell them apart later.
Change Preset Theme on Home and Lock Screen
If your OnePlus home screen and lock screen still look the way they did out of the box, the preset theme is the setting controlling color accents, brightness, and overall tone. Oxygen OS bundles three built-in styles - Vibrant tints, Illuminating light, and Nuanced dark - but the switch sits inside a settings area many users overlook. Picking the wrong one can also affect how icons and widgets read in daylight or at night.
Add a New Tab in Chrome
Switching between product pages on different shopping sites usually means losing the page you were just looking at. On OnePlus phones running the Chrome app, you don't have to close anything to compare prices or articles side by side. A quick tap opens a fresh tab while every other page stays loaded in the background.
Copy Text from an SMS Message
An SMS with a delivery address, a phone number, or a one-time login code often needs to move somewhere else, like a notes app or a browser field. Retyping it risks a wrong digit, and OxygenOS does not show an obvious copy button in the conversation view. The option only appears once you select the message the right way.
Enable Face Unlock
If your OnePlus phone only unlocks with a fingerprint or by entering a pattern, PIN, or password, Face Unlock stays inactive until you register your face separately. Without this step, the front camera has no biometric data to compare against when you pick up the phone. Setting it up once lets the lock screen recognize you automatically instead of asking for a code every time.
Camera Timer: Set the Self-Timer
If your OnePlus photos always fire the instant you tap the shutter, you end up cut out of group shots or with a shaky, blurred frame. The camera app has a built-in countdown for exactly this, but it is easy to miss because it sits in a small icon at the top of the viewfinder. Without it, every family photo depends on someone else holding the phone.
Enable or Disable Hearing Aid Compatibility (HAC)
If your hearing aids pick up static, buzzing or a faint hum during calls on your OnePlus phone, the built-in audio output might not be tuned for hearing aid compatibility. This setting changes how the earpiece sends sound so hearing aids can pick up a cleaner signal, but it can also make calls sound different for people who don't use hearing aids. Getting this setting wrong in either direction leaves one group with poor call audio.
Enable or Disable Colour Correction
If colours on your OnePlus screen look inaccurate or hard to tell apart, especially reds and greens, the built-in colour blindness support might help. OxygenOS includes a colour correction feature that shifts on-screen colours to compensate for common types of colour vision deficiency. Picking the wrong correction mode can leave photos or app graphics looking washed out instead of clearer.
Turn Adaptive Battery On or Off
If notifications from apps you rarely open arrive late or a background app gets killed before it can sync, Adaptive Battery is usually the reason. The feature learns which apps you use often and throttles background access for the rest, even when you still need timely updates from them on your OnePlus phone.
Set Up Private DNS
Every website you open on your OnePlus phone starts with a DNS lookup, and by default that request travels unencrypted across your network. Anyone sharing your Wi-Fi or your mobile carrier can see, log, or even redirect which domains you visit. Private DNS closes that gap by routing the entire lookup through an encrypted connection.
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.
