Turn On High-Contrast Text (Accessibility) auf Android
Standard Android text uses a thin font weight that can blend into busy wallpapers or bright backgrounds. This makes menu labels, app names, and system text harder to read for people with low vision or general glare sensitivity.
High Contrast Text fixes this by adding a heavy black outline around all system and app text, regardless of the background color behind it. The feature does not change font size, only the visual weight and edge definition of each character.
To enable or disable it, go to Tap on Settings ➔ Tap on Accessibility ➔ Tap on Display size and text ➔ Enable or disable High contrast text.
Once turned on, the effect applies system-wide immediately, including notification shades, quick settings, and most apps that follow standard Android text rendering. Some apps with custom UI elements may not fully respect the setting.
If your main issue is text that's too small rather than too thin, use the separate font size slider in the same Display size and text menu instead. Combining both settings can help if readability problems persist after enabling High Contrast Text alone.
