Change Mobile Hotspot Band
If a laptop or older tablet cannot see your OnePlus hotspot at all, or a newer device only gets a weak signal through walls, the wrong Wi-Fi band is usually the cause. The personal hotspot on OnePlus phones can broadcast on either the 2.4 GHz or the 5.0 GHz band, and each has different trade-offs for range and speed. Picking the wrong one for your situation leads to dropped connections or frustratingly slow transfers.
Set a Custom Alarm
If your OnePlus phone only rings with one generic alarm sound at the same time every day, you probably have not set up separate alarms for different days or purposes. The Clock app lets you create individual entries with their own time, name, repetition and tone. Without adjusting these settings per alarm, all your wake-up times end up sharing the same schedule and sound.
Enable System-Wide Captions
If videos in some apps show no subtitles at all, or you want a consistent caption style across your OnePlus phone instead of relying on each app's own subtitle toggle, the system-wide captioning option in Accessibility is the setting you need. This feature works independently from automatic app subtitles and lets you pick a fixed language, text size and caption style. Many users overlook it because it hides deep inside the Accessibility menu instead of the display settings.
Enable or Disable Picture-in-Picture Mode
If a video keeps floating over other apps when you did not ask for it, or a media app refuses to shrink into a small window while you check messages, picture-in-picture permission is likely the cause. This mode lets one app overlay another in a movable box, but each app needs its own permission toggle to use it. Once that toggle gets switched off for an app, the floating window simply stops showing up, even if the app itself supports the feature.
Reset Network Settings (Wi-Fi, Bluetooth, Mobile Data)
Wi-Fi keeps dropping, Bluetooth won't pair, or mobile data refuses to connect even though the signal looks fine? On OnePlus phones this often points to a corrupted connection profile rather than a hardware fault. A full network reset clears these profiles so you can rebuild every connection from scratch.
Change Notification Sound
If the same notification tone keeps going off for every text, WhatsApp message or app alert on your OnePlus phone, it is easy to start tuning it out. OxygenOS comes with a handful of preset tones, and you can add your own audio files once those feel repetitive. The setting that controls this sits a few taps deep in the sound options, which is why many people never change it.
Allow or Deny System Settings Permission
Some apps on your OnePlus phone ask to change system settings on their own, like the wallpaper or ringtone. This permission only covers those convenience settings and has no effect on security features such as the screen lock.
Switch Keyboard Language While Typing
Typing a message that mixes two languages and the keyboard keeps autocorrecting the wrong one gets annoying fast on a OnePlus phone. Most keyboards let you swap languages mid-sentence, but the trigger for that switch is not always obvious. Some people tap a small globe icon near the space bar, others just hold the space bar down and get nothing.
Change App Icon Shape and Style
If every app icon on your OnePlus home screen still looks like a plain square or circle, the icon shape setting is likely still on the default option. Switching between the pre-installed icon packs or a downloaded one changes the outline of every app symbol at once, but the option is easy to miss inside the home screen settings. Some downloaded packs also only apply partially if a step gets skipped.
Change Calendar View
By default, the Calendar app on OnePlus phones opens with a combined overview of every added account, which makes it hard to see a full month at a glance. If you only need a quick daily rundown or a compact weekly plan instead, the current view setting is working against you. This applies to all accounts synced into the app, not just one calendar.
Assign a Default SIM Card to a Contact
If your OnePlus phone keeps asking which SIM to use before calling a certain contact, that contact has no fixed calling SIM set. On dual SIM setups this means every outgoing call to them needs a manual choice, even if you always use the same line for that person.
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.
Change USB Connection Type
When you plug your OnePlus phone into a PC or laptop, it defaults to charging only and blocks file access. If Windows or macOS does not show the phone as a drive, or you need MIDI or PTP mode instead of MTP, the connection mode is set wrong on the phone side.
Add an App Shortcut to the Home Screen
When the app drawer is turned on, your home screen stays mostly empty and every app only shows up in the full overview list. That means an extra swipe and tap each time you want to open something you use daily. Adding a direct shortcut fixes that without switching off the drawer.
Enable or Disable Google Voice Typing
If dictation stays greyed out on your OnePlus keyboard or the microphone icon simply refuses to appear, Google voice typing is likely switched off in your keyboard settings. The feature converts spoken words into text for messages, emails and notes, but it only works once it is active for your virtual keyboard. A locked device after a restart can also block access until you unlock it first.
Disable Screen Animations
If your OnePlus feels sluggish when switching apps or opening menus, fade-in effects and shadows are often the cause. These transition animations use extra graphics processing and RAM every time a window or panel appears. Turning them off frees up resources without changing anything else about how your phone behaves.
Disable Lock Screen Password
If your OnePlus phone still asks for a pattern, PIN or password every time you wake the screen, the lock screen security feature is still active. This also keeps fingerprint and face unlock tied to that passcode, so removing it wipes any saved biometric data. You need your current unlock method on hand before you can turn the request off.
Enable or Disable Switch Access
If touch input is not an option for you, controlling a OnePlus phone can feel out of reach. Switch Access lets you navigate, select items, scroll and type using an external switch connected over USB or Bluetooth instead of tapping the screen. Turning the feature on or off happens in the accessibility settings, not through a hidden gesture.
Enable or Disable Battery Saver
When your OnePlus phone drains faster than usual, background apps, animations and sync jobs are often still running at full power. Battery Saver throttles that activity to stretch the remaining charge, and it can also switch on by itself at a set time, for example overnight while the phone is idle.
Power Button: Choose Power Menu or Voice Assistant
On many OnePlus phones, holding the power button on the side launches Google Assistant instead of the shutdown menu. That makes it awkward when you actually want to restart, power off, or trigger emergency mode. The behavior comes from a setting most people never touch after setup.
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.
Open WiFi Network Notification
If your OnePlus keeps popping up alerts every time you walk past a coffee shop or airport hotspot, the open network notification is doing its job a little too well. This constant pinging gets old fast in busy public areas. You can control exactly when and if these alerts show up.
Enable or Disable Keyboard Auto-Correction
Typing a technical term, a name, or slang on your OnePlus and watching Gboard swap it for a completely different word is frustrating, especially in a WhatsApp chat or a work email you cannot easily edit after sending. Auto-correction speeds up typing for most people, but it also guesses wrong often enough to break sentences or change meaning. If wrong substitutions keep showing up, the fix sits in the keyboard's text correction settings.
Delete a Single Text Message
Sometimes only one message in a long thread needs to disappear, not the entire conversation. On a OnePlus phone, the standard option to clear a whole chat removes far more than you actually want to get rid of. Deleting a single message only changes what you see on your own device, so the other person keeps their copy of it.
