Add and Manage Personal Dictionary Words
When your OnePlus keyboard keeps autocorrecting a name, abbreviation or technical term into something else, the word simply is not part of its known vocabulary yet. This gets annoying fast with names, addresses or industry jargon you type often. Saving the word once, together with an optional shortcut, stops the keyboard from fighting you every time.
Update a saved Wi-Fi password without reconnecting
If your router password changed, your OnePlus keeps trying the old credentials and drops the connection or refuses to join. Forgetting the network and setting it up again works, but it also wipes proxy settings, static IP entries, or metered data flags you configured earlier. Editing the saved entry directly keeps all of that intact.
Allow Calls in Do Not Disturb Mode
If Do Not Disturb on your OnePlus phone silences calls from people who actually need to reach you, the default setup is blocking everyone by mistake. Call and message exceptions in Do Not Disturb are handled separately, so muting WhatsApp or SMS alerts does not automatically decide who can still call you. Adjusting the call exception lets you pick between all contacts, only favorites, or nobody at all.
Quick Search or All Apps in App Drawer
Swiping up on the OnePlus home screen sometimes opens a full grid of apps when you expected a search bar, or the reverse. This mismatch comes from a single toggle in the app drawer settings that decides what the swipe gesture actually triggers. Once you know where that switch lives, the gesture does exactly what you want every time.
Change the Start of the Week in the Calendar App
If your OnePlus Calendar always opens with Sunday as the first column, the app is likely following the week-start rule tied to your phone's region setting. That gets confusing when you travel for work and your team's calendar starts on Monday instead. Oxygenos lets you override this default and pick Saturday, Sunday or Monday as the start of the week.
Enable or Disable Mono Audio
If music or videos suddenly play through only one speaker with both channels squeezed together, Mono audio is likely active on your OnePlus. This accessibility setting merges the stereo channels so left and right output the identical signal. It helps with hearing loss in one ear, but it also removes stereo separation from calls, games and media playback.
Close All Browser Tabs at Once
If you spend a lot of time browsing on your OnePlus phone, the tab count in the Chrome app can quietly climb into the double digits. Closing each one individually wastes time and leaves the app running slower than it should. A single menu option clears every open tab in one go.
Flip to Silence for Incoming Calls
When a call rings loudly in a meeting and there is no time to dig for the phone, flipping it face-down should mute it instantly. On OnePlus phones running OxygenOS, Flip to Silence only works once the option is switched on in the Phone app; until then, flipping the device does nothing to the ringtone or vibration.
Answer an Incoming Call
When your OnePlus phone rings, the incoming call takes over the entire screen along with the ringtone and vibration. Saved contacts show their name next to the number, but the actual answer control is a sliding gesture rather than a simple tap. Tap the icon like a button and nothing happens, so the call keeps ringing until it drops to voicemail.
Enable or Disable Data Saver
If apps stop refreshing content in the background or photos in messaging apps only load after you tap them, Data Saver is likely active on your OnePlus. This mode limits background data usage per app once your mobile data connection kicks in, so updates and previews arrive later than usual. It can also delay push content in social or news apps until you open them directly.
Forward an SMS or MMS Message
Retyping or copying a text just to send it to someone else wastes time, especially with longer MMS content like photos or shared links. The Messages app on OnePlus phones has a built-in Forward option that gets skipped by many users because it hides inside a long-press menu. Without it, important information often gets lost in manual retyping or screenshots.
Set Dwell Timing for Mouse Click
If you connect a USB or Bluetooth mouse to your OnePlus phone, an automatic click can trigger as soon as the pointer stops moving. Depending on the delay you have set, this click may fire too quickly or take far too long, making menus feel unresponsive or overly sensitive. Dwell timing controls exactly how long the cursor has to stay still before that click happens.
Show Weather Details for a City in World Clock
World clock entries on your OnePlus show more than just the local time - each city also carries a small temperature reading next to it. That number alone does not tell you much, and it is not obvious how to see the fuller weather picture for a specific city.
Set a Timer in the Clock App
If the countdown in your OnePlus Clock app keeps running past the time you wanted, or the alert sound never fires, the Timer tab often gets mixed up with the Stopwatch. Both live in the same app but use separate controls for starting, pausing, and resetting. Getting the hours, minutes, and seconds right the first time avoids missed alerts during cooking, workouts, or work breaks.
Enable or Disable NFC
Contactless payment fails at checkout, or your OnePlus won't pair with a speaker or headphones by tap - in most cases NFC is simply switched off. Some users also want to disable NFC on purpose, either to save a bit of battery or to avoid accidental taps against payment terminals in a crowded bag. On several OxygenOS builds the toggle isn't in the quick panel at all, which is why people keep searching for it in the wrong place.
Change Device Name
If your OnePlus phone shows up with an unclear or generic label when you connect to Bluetooth speakers, a car system or your home Wi-Fi, that name comes from the device name setting. It has nothing to do with your phone number, email or OnePlus account, and other users on the same network can see it too. Swapping it for something you actually recognize makes pairing and file sharing far less confusing.
Adjust Display Scaling for Icons and Elements
If icons, buttons, and app elements feel cramped or oversized on your OnePlus, display scaling is usually the cause, not the font size. OxygenOS lets you shrink or enlarge on-screen elements independently from text, which changes how much content fits per screen. Get this wrong and menus can overflow or buttons become hard to tap.
Add Trusted Places to Smart Lock
If your OnePlus phone keeps locking itself at work or another spot you visit daily, Smart Lock can leave it unlocked there instead of forcing a PIN or pattern every time. Without a saved location, the normal screen lock rules apply everywhere, even places you trust. That means repeated unlocking in spots where it is not really needed.
Connect to Wi-Fi Using a QR Code
Typing a long Wi-Fi password on a shared or guest network gets tedious fast, especially with mixed-case letters and symbols. Scanning a QR code lets your OnePlus phone join the network without any manual entry. This works with a printed code or one generated by another device already connected to that network.
Show Network Speed in Status Bar
If your status bar only shows signal bars and no numbers, you can't tell whether your connection is actually fast enough for streaming or a big download. OnePlus phones can display live download and upload speed right next to the clock, but the toggle sits inside the display settings and is easy to overlook. Without it enabled, you only notice a slow connection once a video buffers or a transfer stalls.
Send Photos or Videos via Bluetooth
Sending a photo or video from your OnePlus phone to a laptop, smart TV or another smartphone only works once both devices are paired over Bluetooth. If the Bluetooth entry is missing from the Share menu, or the paired device never shows up in the list, the transfer stalls before it starts. This applies to photos, videos and PDF files the same way.
Enable Emojis in the Symbols Keyboard
When you switch to the symbols keyboard on your OnePlus, recently used emojis do not show up above the number row. This forces you to jump back to the emoji picker instead of tapping a quick suggestion. A single Gboard setting controls whether that emoji strip appears at all.
Enable or Disable Google Autofill Service
If login fields, payment details or addresses fill in on their own on your OnePlus, Autofill with Google is doing the work in the background. That is convenient, but it also means saved passwords and card numbers sit ready to insert wherever a matching field shows up. Some people want that speed, others prefer to enter sensitive data manually every time.
Uninstall an App
When storage runs low on your OnePlus phone or an app keeps crashing, removing it is often the fastest fix. Uninstalling deletes the app along with its data, so chat histories, saved logins, and offline files disappear too. Before you remove anything important, it helps to know what actually gets erased and what stays behind.
