Change Font Size
When text on your OnePlus looks too small to read comfortably, or too large and cramped, the system font scale is usually the cause. Apps without their own text settings simply inherit whatever size you set at the system level, which affects menus, notifications, and most third-party apps at once.
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 Accessibility Menu
If the Accessibility Menu button is missing from your navigation bar, shortcuts for Assistant, power control, volume and recent apps are not available in the enlarged panel. The feature depends on a separate permission toggle, so switching it once in the wrong place leaves it off. Turning it back on restores the larger on-screen controls for anyone who relies on simplified navigation.
Disable TalkBack
If TalkBack turns every tap into a double-tap and swipes now switch between items instead of scrolling, the accessibility service is still running in the background. Reaching the toggle to stop it feels different from a regular settings visit, since TalkBack itself changes how you interact with menus while it is active.
Enable or Disable Magnification (Accessibility Zoom)
Small text and icons on your OnePlus can be tough to read, especially in apps that ignore your font size settings. The Magnification accessibility feature lets you zoom in with a triple-tap or a dedicated shortcut, but it stays off until you switch it on. If tapping the screen three times keeps zooming in by accident, the same setting is the cause.
Enable TalkBack Screen Reader
If you need spoken feedback to use your OnePlus without looking at the display, TalkBack reads out every item you touch on screen. Once it is turned on, normal taps stop working the way you expect: a single tap only selects an item, and you swipe left or right to move between elements. That changed behavior catches many people off guard the first time they turn it on, whether on purpose or by accident.
TalkBack Feedback Settings for Inputs
If TalkBack stays silent on some taps or buzzes too loudly during a call, the vibration, sound and audio ducking options are likely not tuned to your needs. OnePlus lets you fine-tune each feedback channel separately, including how much other audio gets muted while TalkBack speaks. Getting these settings wrong can make TalkBack hard to notice or disruptive during media playback.
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.
Enable or Disable High Contrast Text
Small, thin fonts on a OnePlus display can be hard to read in bright light or with low vision. The High contrast text option in Accessibility settings widens text margins and sharpens edges for better legibility, but it stays off by default on most phones. If menus and app labels blend into the background, this setting is usually the missing piece.
Change TalkBack Speech Rate and Pitch
TalkBack reads screen content aloud, but the default speech rate can feel too slow or too fast for daily use. When the voice output rushes through notifications or lags behind your taps, the Text to speech settings inside TalkBack control that pace. Pitch and rate work independently, so you can fine-tune the voice without switching your default OS language.
Enable One-Handed Keyboard Mode
When you hold your OnePlus with just one hand, the Gboard keyboard often stays too wide for your thumb to reach the far edge. Typing single-handed then means stretching your thumb or shifting your grip with every message. One-handed mode shrinks the keyboard and pins it to whichever side fits your hand.
