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.
Share Contacts
Forwarding a phone number often means retyping every detail by hand, from address to birthday. OnePlus lets you send contact details straight from the Contacts app, but the sharing option sits inside a menu that is easy to miss if you have never used it before.
Custom Notification Sounds for Individual Apps
If every app on your OnePlus phone plays the same sound when a notification arrives, it gets hard to tell a chat message from a calendar reminder without looking at the screen. This happens because most apps just use the default system notification sound unless you assign a custom tone in Oxygenos. You can pick a different sound per app, including your own audio files, directly from the notification settings.
Use Google Lens in the Camera App
If the camera viewfinder does not recognize landmarks, text or products on its own, Google Lens is probably still hidden inside the camera shortcuts. On OnePlus phones running Oxygenos, Lens sits as a separate option in the Camera app and only scans the frame once you tap it and pick a category.
Print a Website from the Browser App
If the print option seems missing when you open a website on your OnePlus phone, it is usually hidden inside the Share menu instead of a dedicated print button. The browser relies on the Android print framework, so the printer also needs to be reachable over the same Wi-Fi network, Bluetooth, or Wi-Fi Direct before anything shows up.
Add More Exceptions to Do Not Disturb Mode
Do Not Disturb on your OnePlus phone mutes calls and messages by default, but alarms, media playback, and touch feedback often keep misbehaving anyway. If you want alarms to still go off, media sounds to stay audible, or touch sounds to work while everything else is silenced, the standard call and message exceptions will not help. Those extra behaviors sit in a separate exceptions list that needs to be turned on manually.
Change System Language
Stuck with the wrong system language after setting up your OnePlus phone? The region and language chosen during initial setup stay active until you manually switch them, and there is no need to reset the device to fix this. A quick adjustment in the language settings solves it without losing any data.
Turn Screenshot Sound On or Off
Every screenshot on your OnePlus triggers a camera-shutter style sound by default, even when the phone is set to silent or you are in a quiet room. This acoustic feedback comes from a system sound setting tied to screen captures and can catch you off guard during meetings or at night.
Add an Alternate Calendar to the Calendar App
If the Calendar app only shows the standard Gregorian dates, you are missing a second date system next to the regular calendar view. OnePlus lets you display an alternate calendar such as Chinese, Simplified Chinese, Traditional, Hebrew or Hijri right below the main dates. The feature sits in a settings area that is easy to overlook on first use.
Create Contact Group
Sending the same text to five different chats or emailing your whole team one by one wastes time on a OnePlus phone. The Contacts app supports labels that bundle several people under one name, but the option to create one sits hidden inside the app's menu instead of its own tab. Without a label, group messages and group emails still mean picking every recipient manually.
Automatic Night Mode Schedule
If you keep forgetting to switch Night mode on in the evening or off again in the morning, manual toggling is the actual problem, not the feature. OnePlus lets you tie Night mode to a fixed time window or to sunset and sunrise, but the automation only works once the correct trigger rule is active. Pick the wrong option and the warm tint either stays on all day or never kicks in at night.
Set Calendar Event Colors by Category
When appointments from different Google Accounts, birthdays, and personal events all appear in the same shade, the Calendar app on your OnePlus gets hard to scan at a glance. Each event category can carry its own color, but the option sits inside the calendar settings and is easy to miss. Without it, a work meeting and a birthday reminder look identical in your day view.
Make Pattern Visible: Enable or Disable
If you use the Pattern unlock method on your OnePlus phone, the line you draw stays visible on screen while you enter it. Anyone standing close enough can watch the shape you trace and memorize your unlock pattern. This visible trail turns a private security feature into a risk for your personal data.
Unpair a Bluetooth Device
If a OnePlus phone keeps reconnecting to a Bluetooth speaker, inEars, or a laptop you no longer use, the old pairing entry is still sitting in the device list. That stored entry can grab audio playback automatically as soon as the other device is nearby and switched on. Removing the pairing clears the entry completely instead of just switching the connection off.
