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.
Turn Touch Vibration On or Off
If every tap, menu selection or navigation button on your OnePlus triggers a short buzz, that is the touch vibration feedback kicking in. Some people rely on that haptic confirmation, others find it distracting or draining on battery over time. Either way, the behavior is controlled by a single toggle you can flip whenever you want.
Remove App Shortcut from Home Screen
When your OnePlus home screen fills up with shortcuts you barely use, finding the apps you actually need takes longer every time. Deleting the wrong icon by accident or confusing 'Remove' with 'Uninstall' is a common worry, since both options can appear in the same long-press menu. Knowing which action just clears the shortcut and which one deletes the app entirely saves you from losing data you did not mean to remove.
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.
Restrict Notifications in Do Not Disturb Mode
When Do Not Disturb is active on your OnePlus phone, some notifications still light up the screen or buzz next to you. That happens because Restrict notifications defaults to letting partial alerts through instead of blocking them fully. You can set exactly how much a notification is allowed to interrupt you while the mode runs.
Add App to Do Not Disturb Exceptions
If notifications from a specific app stay silent even though Do Not Disturb is active on your OnePlus, the app is missing from the exception list. This mostly affects messaging or call apps where you still want alerts to break through. The fix sits inside the notification settings of that single app, not in the general Do Not Disturb menu.
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.
Set Camera Aspect Ratio
If your photos come out square when you wanted a wide landscape shot, or a portrait leaves odd black bars, the camera aspect ratio on your OnePlus is probably set wrong for what you are shooting. The Camera app offers different formats depending on your phone screen ratio, and the wrong pick crops out parts of the scene or adds unwanted space around your subject. Switching between 4:3, Full and 1:1 changes exactly how much of the frame actually gets saved.
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 Emoji Suggestions
If Gboard keeps popping up an emoji next to a word while you type on your OnePlus, the emoji suggestion feature is active. Some people find this handy, others just want a clean suggestion bar without extra icons. The setting sits inside the keyboard text correction options, not the main keyboard layout menu.
Set Mobile Data Warning Limit
If your OnePlus phone never tells you when you are close to your mobile data cap, the data warning notification is probably switched off or set too high. Without an early alert, you only notice the overage once your carrier already throttles or bills extra data. A properly set warning threshold gives you time to cut back before the actual limit is reached.
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.
Auto-download MMS: Enable or Disable
MMS attachments like photos or videos download automatically as soon as a message arrives, even on a limited data plan. On a OnePlus phone with two SIM cards, this setting exists separately for each SIM and can quietly burn through mobile data while roaming. Turning it off gives you back control over when attachments actually load.
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.
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.
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.
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.
