Mark All Messages as Read
If your Messages app on your OnePlus phone is cluttered with unread badges after a busy weekend, opening every single conversation just to clear the counter wastes time. OnePlus includes a shortcut that clears the unread marker on all conversations in one tap, without touching the content of any chat.
Rename a Home Screen Folder
Folders on your OnePlus home screen often keep the generic name that was assigned automatically when you created them, making it hard to tell them apart at a glance. Renaming them helps you group apps by category or keep the ones you use most together for faster access. The option sits directly on the folder itself, not buried in a settings menu.
Enable or Disable the Home Screen Assistant
Keep swiping right across your OnePlus home screens and you land on the Discover panel, packed with a Google feed, news topics and a search bar that reacts to Hey Google or typed input. If that panel opens by accident, eats battery in the background or just clutters your setup, the home screen assistant is the toggle behind it. Turning it off removes the whole panel, not just the search bar.
Allow or Deny Display Over Other Apps
If a chat bubble or profile picture from Facebook Messenger keeps floating over other apps on your OnePlus phone, an app is using the display over other apps permission. Some apps ask for this access right away, while others use it silently in the background. Knowing which apps hold this permission lets you decide which overlays you actually want on screen.
Share Internet Access via Bluetooth
If a paired laptop, tablet or second phone cannot get online through your OnePlus, the Bluetooth connection itself is often fine but data sharing is switched off. Bluetooth pairing alone does not grant internet access, that permission has to be enabled separately for each paired device. Without it, the linked gadget stays connected but offline.
Show or Hide Calendar Accounts
If you have linked several Google accounts on your OnePlus, the Calendar app shows every event, reminder and task from all of them at once. That makes the monthly view crowded and hard to scan for a specific account or category. You can turn individual accounts or categories on or off without removing the account itself.
Show or Hide Declined Calendar Events
When you decline a meeting invite on your OnePlus phone, the event usually disappears from the calendar view completely. That makes it hard to check what you turned down or to review past commitments you rejected by mistake. The calendar app has a setting that controls whether declined events stay visible or stay hidden.
Contact List Name Format
If your OnePlus contact list shows entries as Last, First instead of First Last, or the other way round, one system setting controls that order for every saved contact at once. It has nothing to do with how the individual entries were sorted or saved.
Change TalkBack Speech Rate and Pitch
TalkBack reads screen content aloud, but the default speech rate can feel too slow or too fast for daily use. When the voice output rushes through notifications or lags behind your taps, the Text to speech settings inside TalkBack control that pace. Pitch and rate work independently, so you can fine-tune the voice without switching your default OS language.
Switch Between Gesture and Button Navigation
If the Back, Home and Recents bar keeps eating into your screen, or your OnePlus suddenly swipes instead of using buttons after an update, the navigation mode setting is behind it. OnePlus offers both classic button navigation and gesture navigation, and many people only notice the option once they want a cleaner screen or accidentally trigger the wrong mode. Picking the right one changes how you go back, go home and switch apps on every screen.
Change Default Dialer App
If the stock Phone app on your OnePlus feels limited or the call screen does not match the rest of your setup, you do not have to keep using it. Third-party dialer apps from the Google Play Store can take over outgoing calls, contact lookup and the call screen instead.
Save a Web Page as PDF
Trying to keep a web page for later reading or printing without an internet connection can be tricky if you do not know where the export option is hidden. On OnePlus phones the browser's Share menu doubles as a print and PDF export tool, even without a connected printer. Many people miss this because it looks like a printing feature rather than a save option.
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.
Enable or Disable Mirrored Selfie Photo
If your OnePlus selfies look flipped compared to what you see in the mirror, the front camera is mirroring the preview but not the saved photo, or the other way around. Text and objects in the background can end up reversed, which looks odd in group shots or when a sign is visible behind you. This comes down to a single camera setting that controls how the final image gets saved.
Take a Photo with the Camera App
New OnePlus owners often can't find the actual shutter button or end up with blurry shots because the camera app opened in the wrong mode. Oxygen OS switches between Photo, Video, and Portrait with a simple swipe, so it's easy to tap the wrong icon without noticing. Filters and exposure settings applied before the shot can also change how the picture turns out compared to what you expected.
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.
Schedule Battery Saver
If your OnePlus phone only saves power when you flip the switch yourself, you are missing out on automatic protection before the battery actually runs low. Battery Saver can turn on by itself, either based on your daily routine or once the charge drops to a set percentage. Without a schedule configured, the phone waits for you to notice the low battery, which often happens too late.
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.
Auto-Download System Updates over Wi-Fi
If your OnePlus keeps pulling firmware updates over your mobile data plan, or never downloads them until you check manually, the Auto-download over Wi-Fi setting is controlling that behavior. Once enabled, updates download automatically the moment your phone joins a wireless network, and you get notified when installation is ready. Turning it off stops silent downloads but means you have to check for updates yourself.
Enable or Disable Usage & Diagnostics Data
Every OnePlus phone quietly sends app usage and diagnostic data to Google in the background. If you are unsure why battery stats, crash reports or app activity seem to leave your device, this setting is the reason. It sits deep in the privacy menu and is easy to miss.
Screen Saver Content Settings
If your OnePlus screen saver only shows the default clock and you want your own photos or a color display instead, the option is hidden inside a separate content menu. Depending on whether you pick Clock, Colors or Photos, extra settings like Analog or Digital style, or Night mode, only show up once you have chosen the right content type first.
Turn an Alarm On or Off
If you keep deleting and recreating the same wake-up time on your OnePlus phone, you are doing more work than necessary. Every alarm in the Clock app has its own switch, so you can pause a single alarm for the weekend without losing its time or repeat days. This works independently of Do Not Disturb or Focus mode, which mute every alert at once instead of a single alarm.
Add or Remove Bookmarks in Chrome
Losing track of a useful page you found on your OnePlus is annoying when you cannot find it again later. Chrome lets you bookmark any page, then rename it, adjust its saved URL, or move it into a specific folder for faster access next time. If a saved page is no longer useful, removing the bookmark keeps your list tidy and easy to scan.
Enable or Disable Emergency Location Service (ELS)
When you dial an emergency number on a OnePlus phone, the device can send your location automatically even if Google Location Services are switched off. Some users want to stop this behavior, others find that ELS silently re-enables location access during a call and are unsure whether that is expected. The setting sits in a spot most people never check until an emergency call raises the question.
