Factory Reset: Erase All Data
If your OnePlus phone keeps lagging, misbehaving after a failed update, or you are getting it ready to sell, a factory reset clears every trace of your data. Once triggered, it wipes your linked Google account, all system and app settings, and every installed app - permanently. Knowing what disappears before you confirm helps you avoid losing files you still need.
Enable or Disable Touch Sounds
Every tap on a menu item or navigation key triggers a short tone on your OnePlus phone, and that constant clicking can get annoying fast in quiet rooms or during calls. The sound comes from a system setting for touch feedback that most people never touch after setup.
Touch & Hold Delay
If a long-press on an app icon or list item pops up its context menu too quickly, or feels sluggish before it reacts, the touch and hold delay on your OnePlus is set to the wrong value for how you actually tap. This timing decides how long you must keep pressing before OxygenOS treats it as a hold instead of a normal tap. A mismatched delay leads to accidental menus opening or a noticeable lag before options show up.
Assign Alarm Functions to Volume Buttons
When an alarm rings on your OnePlus phone at night, the side volume buttons can control it instead of the screen. Some people want a quick snooze, others want the alarm to stop immediately with one press, and some prefer the buttons to do nothing so nobody silences the alarm by accident. If the wrong option is set, you might snooze an alarm you actually meant to turn off.
Record Screen as Video
Trying to capture a game session or a quick tutorial on your OnePlus, but you can't find a working screen recorder in the app drawer? The built-in Screen recorder tool sits inside the quick settings, not as a separate app, which is why many people miss it. Once it's running, a small floating control appears on screen, and tapping the wrong spot can stop the recording before you're done.
Restrict Apps to Wi-Fi Only or Mobile Data
If Netflix, YouTube or another streaming app keeps eating through your mobile data plan even when you are near a router, it is likely still allowed to use mobile data in the background. OxygenOS lets you lock individual apps to Wi-Fi only, or the reverse, so they never touch your cellular connection again. This is separate from the general data saver toggle and works per app.
Change Lock Screen Wallpaper
If your lock screen still shows the default rotating daily image instead of your own photo, the wallpaper picker on OnePlus phones treats the lock screen and home screen as two separate slots. Many users only change the home screen and wonder why the lock screen keeps switching on its own. The fix sits inside the Customization menu, not the regular wallpaper shortcut.
Schedule Do Not Disturb Mode
Turning Do Not Disturb on and off by hand every night or before every meeting gets old fast, and it is easy to forget switching it back off, leaving missed calls and messages piling up. On OnePlus phones, the Do Not Disturb schedule inside Sounds & vibration can handle that timing for you, based on either a fixed time window or calendar events. Multiple schedules can run at once, each with its own days and hours.
Disable Gmail Event Sync in Calendar
Booking a flight or a restaurant table on your OnePlus phone can suddenly add an extra appointment to your Calendar app that you never created manually. This happens because Gmail automatically forwards detected reservations and bookings as calendar events for every linked Google account. If you only want your own manually added appointments to show up, that automatic sync needs to be turned off.
Enable or Disable Spam Protection in Messages
If the Messages app on your OnePlus keeps flagging normal texts as junk, or unwanted spam keeps slipping through unfiltered, the built-in spam protection setting is worth checking. This feature scans incoming messages and reports rough details to Google, without sending your phone number or the message content itself. You can switch it on or off depending on how much filtering you actually want.
Install an App from the Google Play Store
Not sure whether the app you found online is safe to install on your OnePlus, or why the Install button in a store listing sometimes stays greyed out? The Google Play Store is the built-in source for messengers, games and system tools, but search results, region locks or missing sign-in can get in the way of a straightforward install.
Add a Second Account
After the first setup, your OnePlus phone only keeps the Google Account you signed in with during activation. If you use a second Gmail address, a work Exchange account, or an Outlook inbox, none of that syncs until you register it separately. Apps like Facebook or WhatsApp handle their own login and never show up in this list.
Pair a Bluetooth Device
If your OnePlus phone does not detect your headphones, speaker, or inEars, the accessory is often still in a locked pairing state or Bluetooth is switched off on the phone. Sometimes a short PIN prompt shows up during the connection and has to be confirmed on both sides before audio actually starts working.
Control App Data Usage
If YouTube or Netflix keeps burning through your mobile data plan even when you did not mean to stream over cellular, a background permission is usually the cause. OxygenOS lets you set a data policy for every single app, but most people never open that screen. Without a manual override, apps default to using whatever connection is available, including your mobile data.
Enable Face Unlock
If your OnePlus phone only unlocks with a fingerprint or by entering a pattern, PIN, or password, Face Unlock stays inactive until you register your face separately. Without this step, the front camera has no biometric data to compare against when you pick up the phone. Setting it up once lets the lock screen recognize you automatically instead of asking for a code every time.
Enable or Disable Hearing Aid Compatibility (HAC)
If your hearing aids pick up static, buzzing or a faint hum during calls on your OnePlus phone, the built-in audio output might not be tuned for hearing aid compatibility. This setting changes how the earpiece sends sound so hearing aids can pick up a cleaner signal, but it can also make calls sound different for people who don't use hearing aids. Getting this setting wrong in either direction leaves one group with poor call audio.
Enable or Disable Colour Correction
If colours on your OnePlus screen look inaccurate or hard to tell apart, especially reds and greens, the built-in colour blindness support might help. OxygenOS includes a colour correction feature that shifts on-screen colours to compensate for common types of colour vision deficiency. Picking the wrong correction mode can leave photos or app graphics looking washed out instead of clearer.
Set Up Private DNS
Every website you open on your OnePlus phone starts with a DNS lookup, and by default that request travels unencrypted across your network. Anyone sharing your Wi-Fi or your mobile carrier can see, log, or even redirect which domains you visit. Private DNS closes that gap by routing the entire lookup through an encrypted connection.
Turn Call Vibration On or Off
If your OnePlus phone buzzes every time someone calls even though you only want the ringtone, or the vibration stays off in a quiet room where you actually need it, the culprit is a separate vibration setting tied to Phone ringtone and vibration. Ringtone volume and vibration are controlled independently on OxygenOS, so muting one does not affect the other.
Set a Custom Notification Sound
Every SMS or Messenger alert on your OnePlus still plays the same stock tone, even after you scroll through the built-in sound list twice. OxygenOS does support your own audio files as notification sounds, but the option to load a custom file sits one menu deeper than the regular tone picker. Until that file is placed correctly on your phone, the system keeps falling back to the default ringtone.
Enable or Disable TTY Mode
If a hearing or speech aid device cannot connect to calls on your OnePlus, TTY mode is probably switched off in the Phone app. Without it, the phone cannot convert voice to text or text to voice during a call, which makes standard calling unusable for TTY users. The setting sits in the accessibility options of the Phone app and is off by default.
Forget a Wi-Fi Network on OnePlus
If a OnePlus phone keeps connecting to a Wi-Fi network with no internet or repeatedly drops the connection, the stored network profile is often the cause. An outdated password or a corrupted saved entry can block a fresh connection attempt. Removing the saved network forces the phone to treat it as new the next time you connect.
Add Contact to Favourites
Calling the same person over and over means scrolling through your whole contact list every time on your OnePlus phone. Marking that contact as a favourite pins it to the top of the Contacts app, so you skip the search entirely. It is a quick fix if you keep hunting for the same few names.
Enable or Disable Call Barring
If you are traveling abroad with your OnePlus and want to avoid unexpected roaming charges, call barring lets you block specific call types before they even connect. You can restrict outgoing calls, incoming calls, or international calls depending on which option you activate. Without the right setting enabled, calls still go through as usual and charges keep piling up.
