How to change font size and contrast
Android and iOS have both built-in native tools for making your installed apps more usable. You can set the size, weight of fonts, use high contrast colors or color corrections, and many other tools.
- You can change your font size and display size to make your screen easier to see
- High contrast makes text easier to read on your device. This feature fixes the text color as either black or white, depending on the original text color.
- Color correction setting helps your device compensate for color blindness.
- Do you need to enlarge the screen only sometimes? You can use magnification to see your Android device's screen better.
iOS has a nice presentation on accessibility features at https://www.apple.com/accessibility/
They too have a wide range of tools which can make your experience better. We encourage you to take control of your device and set it up the way you prefer.
