If text messages on your OnePlus 15 refuse to zoom in, reading long conversations can become tiring very quickly. Pinch gestures may do nothing, or the text size might stay the same no matter what you try. This issue is usually tied to app settings, system display options, or accessibility features, and it can be fixed with a few focused checks.
Why Text Messages on Your OnePlus 15 Will Not Zoom In
- The Messages app does not support pinch to zoom for text size.
- System font size is set too small.
- Display zoom is disabled at the system level.
- Accessibility features are turned off or misconfigured.
- The messaging app needs to be refreshed or updated.
1. Increase System Font Size
The Messages app relies on the system font size rather than pinch gestures. If the font is too small, zooming inside the app will not work at all.
Open Settings, and then tap Display.
Tap Font size, and then move the slider to increase text size.
2. Enable Display Size Zoom
Display size zoom scales the entire interface, including text messages. This helps if increasing font size alone does not make enough of a difference.
Open Settings, and then tap Display.
Tap Display size, and then select a larger zoom level.
3. Use Accessibility Text Scaling
Accessibility text scaling applies stronger text enlargement across apps. This is useful if standard font adjustments still feel too small.
Open Settings, and then tap Accessibility.
Tap Text and display, and then increase the text scaling slider.
4. Check Messages App Settings
Some messaging apps limit text resizing within conversations. Refreshing the app settings ensures it is following system-wide text rules.
Open the Messages app, and then tap the three-dot menu.
Tap Settings, and then review display or conversation options.
5. Restart the Messages App
Temporary app glitches can prevent text from updating correctly. Restarting the app forces it to reload display preferences.
Open Recent apps, and then swipe away Messages.
Reopen the Messages app, and then test text size again.
6. Restart Your OnePlus 15
If the issue persists, the system may not be applying display changes properly. A restart refreshes system services and display scaling.
Open Quick Settings, and then tap the Power icon.
Tap Restart, and then wait for the phone to boot up fully.
Text messages on the OnePlus 15 are designed to follow system display settings rather than manual zoom gestures. Once you adjust font size, display zoom, or accessibility options, messages become much easier to read.
