Remove an Account on OnePlus
Old logins pile up in the account overview on your OnePlus phone and make it harder to spot the ones you actually use. Removing an account deletes its login credentials and any data that was synced through it, while the app it belongs to stays installed. This matters most for accounts like WhatsApp or Facebook, where contacts, messages, or cloud-synced content tied to that login disappear from the device once it's removed.
Change Lock Screen Clock Style
If the default lock screen clock on your OnePlus phone looks plain, you don't have to keep it. Some styles only show digits, while others add an analog face or a date line underneath the time. Which one fits depends on a setting most people never open.
Resize a Widget
Some widgets on your OnePlus home screen refuse to shrink past a certain point, while others leave awkward empty space you cannot fill. The resize behavior depends entirely on how the widget was built, and not every widget supports free scaling. Knowing which widgets are flexible saves you from rearranging your whole home screen for nothing.
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.
Call History Name Format Setting
If contacts in your call history show up as Last, First instead of First Last (or the other way around), it usually comes down to a display setting in the Phone app, not the contact entries themselves. This mix-up gets confusing fast when you are scanning recent calls for a specific person. The fix does not touch your saved contacts, only how names are displayed in the call list.
Change Default Homepage in Chrome
If Chrome always opens to the same news feed with shortcuts and suggested articles when you launch it, the browser is using a preset homepage instead of a site you picked yourself. On OnePlus phones this default start page ships active out of the box and keeps loading until you override it. You can swap it for any web address you actually use every day.
Turn Off Instant Power Button Lock
If you tap the power button on your OnePlus even for a second, the screen locks right away and asks for your PIN, pattern or fingerprint again. That gets annoying when you only wanted to check the time or accidentally bumped the button. A setting inside the lock screen options controls whether the power button locks the phone instantly or with a short delay.
Enable or Disable the Suggestion Strip
When typing a WhatsApp message or email on your OnePlus, Gboard normally shows a row of word suggestions above the keyboard based on what you have already typed. If that row is missing, cluttered, or keeps popping up when you do not want it, the Show suggestion strip option is likely set the wrong way. This affects how fast you can type and how much of the screen the keyboard takes up.
Enable or Disable Mobile Hotspot
If your laptop or tablet cannot see your OnePlus phone's WiFi hotspot, or the connection keeps dropping, the toggle for it is not in the quick settings panel on OxygenOS. It sits inside the network menu together with the hotspot name and password. Leaving it on unnecessarily also drains the battery faster than a normal WiFi connection.
Allow App Installs from Unknown Sources
Trying to install an APK outside the Google Play Store and getting blocked on your OnePlus phone? Your browser or file manager needs explicit permission before it can install anything from outside the store. Without that permission enabled, Android refuses the installation as a security precaution.
Set a Mobile Data Limit
If mobile data keeps running past what you planned to use, your OnePlus phone can cut it off automatically. This relies on a feature called Automatic Disconnection of Network Connections combined with a data limit you define yourself. Once usage hits that value, mobile data switches off and stays off until the next billing cycle starts.
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.
Adjust screen brightness manually
If the screen on your OnePlus phone feels too dim indoors or too bright at night, automatic brightness is often making the call instead of you. Once Adaptive Brightness kicks in, the slider can jump around on its own, making it hard to lock in a comfortable level. Setting the brightness by hand gives you a fixed, predictable result every time.
Auto-Download of MMS Files via Mobile Data
When you are away from a Wi-Fi network, incoming picture or video messages on your OnePlus can quietly pull data through your mobile plan. Without a size cap, a single large attachment can eat into your monthly allowance before you even open the message. The Messages app lets you set a download limit for exactly this situation.
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 Lift to Wake
If your OnePlus screen keeps lighting up every time you pick up the phone or just shift it in your hand, the motion sensor behind 'Pick up your phone to show' is reacting too eagerly. That constant wake-up drains battery faster and can expose your lock screen notifications at moments you did not intend. The setting is meant to save you a tap when checking the time, but it often triggers from pocket movement or when passing the phone between hands.
Reset App Preferences
If several apps on your OnePlus suddenly stay silent, open the wrong default app, or get stuck with a permission you blocked weeks ago, tracking down the exact toggle takes forever. Usually a mix of disabled apps, blocked notifications, stuck default app choices, and background data limits piles up over time. A single system reset clears that whole layer without deleting any app data.
Set Up Bedtime Mode
If your OnePlus screen stays in full color and notifications keep buzzing right before you fall asleep, the built-in bedtime routine probably isn't active yet. Without a schedule, the phone never dims its colors or silences alerts on its own, so late-night scrolling gets no visual cue to stop. Bedtime mode ties grayscale and silence to a fixed time window or to your charging habit, so it works without you touching a single toggle each night.
Show or Hide the Specs Watermark in Photos
Photos from your OnePlus camera sometimes carry a small text stamp in the lower left corner naming the device model and camera technology. If you want a clean image without that branding, or you want it back for sharing, the toggle sits inside the camera app itself. Not knowing where to look often means people just live with photos they did not choose the look of.
Silence Alarms After a Set Time
If your OnePlus alarm keeps blaring long after you have already woken up, it can disturb the rest of the household or even the neighbors through thin walls. The Clock app lets you set a fixed duration after which the alarm stops on its own instead of ringing indefinitely. Without this limit, an unattended alarm just keeps sounding until someone dismisses it by hand.
Enable or Disable a SIM Card
On a Dual SIM OnePlus phone, one line sometimes needs to be shut off completely instead of just switched to the background. Turning off a SIM card stops it from receiving calls and texts right away, while mobile data and messaging priorities move automatically to the remaining card. This is useful when a second line sits unused for a while but should not be removed from the tray.
Add a Printer Manually by IP Address
If your OnePlus phone does not detect your printer automatically, the built-in Default Print Service probably does not recognize your model. This happens with older or less common printers that are not listed in the supported device catalog. You can still connect the printer over your local network by entering its IP address directly.
Enable or Disable Screen Rotation
When you tilt your OnePlus sideways, the whole screen content flips with it, which helps when you are browsing a website or watching a video in landscape. The same behavior gets in the way when a photo, a game, or a fixed app layout rotates on its own at the wrong moment. If Auto-rotate keeps flipping your display unexpectedly, or refuses to rotate when you actually want it to, the setting controlling this behavior lives in the display options.
Add Members to a Contacts Group
A label or group in the OnePlus Contacts app stays empty until you actually assign people to it. Many users create a group but then struggle to find where to add contacts afterward, especially when they want to select several people at once instead of adding them one by one.
