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.
Enable or Disable Long Press for Symbols on the Keyboard
If letter keys on your OnePlus keyboard show no secondary symbol, you have to switch to the symbols layout every time you need a special character. Long press for symbols adds a small extra character to each key, letting you insert it by holding the key instead. This setting sits inside the keyboard app itself, not in the general display options, which is why many users miss it.
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.
Show or Hide the Lockdown Option in the Power Menu
When you enable the Lockdown option, your OnePlus phone drops back to PIN or password entry the moment you tap it from the power button menu. Face Unlock, Fingerprint Scan and Smart Lock all get disabled instantly, which is handy for handing over the device or protecting it from unwanted access, but confusing if you never turned that toggle on yourself. Some users only notice the extra entry in their power menu and want to know where it came from or how to remove it again.
Dark or Light Theme for the Browser App
If the Chrome app on your OnePlus phone still shows a bright white page at night, the browser theme is probably set to follow the system or is stuck on light mode. A dark surface reduces glare and makes long reading sessions on the web easier on your eyes.
Block or Unblock a Contact
Getting repeated calls or texts from the same number on your OnePlus phone points to a contact that needs blocking through the Contacts app. If you already blocked someone and now want them back, the reverse process works differently and trips up a lot of users. Both actions run through the contact's own menu, not through Phone or Messages settings.
Rename a Contact Group
Typing errors creep in fast when you first set up group labels in the Contacts app, and a name that made sense last month can suddenly feel confusing. On OnePlus phones, a label used for calls and messages does not update on its own just because your contact list changed around it. Fixing the name only means finding the right spot in the label menu.
Change TalkBack Navigation Settings
Once TalkBack is running on your OnePlus phone, every tap and swipe controls the screen differently, and the default behavior does not always fit how you want to use the device. Single-tap activation and the context menu list decide how fast items get selected and how the options menu is displayed. Left on the wrong setting, the phone can feel unresponsive or the menu becomes hard to read.
Add a Contact Photo
If a contact shows up as a plain gray silhouette instead of a picture, incoming calls and texts on your OnePlus phone give you no visual clue about who is reaching out. That gets confusing fast when several contacts share a similar first name or when you are scrolling through a long list looking for someone.
Allow Phone Calls and SMS for Added Users
When you add a second user profile on a OnePlus phone, that account cannot make calls or send texts by default. The Phone and Messages apps stay locked until you switch on a specific permission for that profile. Once active, call logs and SMS threads become shared across every user on the device.
Switch Between 12- and 24-Hour Clock Format
When your OnePlus clock suddenly shows military time after setting up a new region, or you want the classic AM/PM display back on your lock screen, the format did not change by itself. OxygenOS ties the hour style to your selected region, so you need to switch it manually to get the display you are used to. Without this fix, every screen showing the time keeps the format tied to whatever region you picked during setup.
