Does the default system font look too small or too large? Do you want to globally change the text size?


This app allows you to scale system font size from 20% (smaller) to 1000% (bigger).

  •  turns your device into a magnifying glass by using camera zoom, auto-focus and LED flash
  •  working for Android 2.3 and greater devices
  •  scale system font size from 20% to 1000%
  •  preview the scaled text before applying
  •  show a notification icon describing the current font size. An option is also provided to hide it

  •  for Android 2.3~3.x users. You can add "not working" apps into the ignored apps list



  • CAMERA: used for the magnifier function
  • BIND_ACCESSIBILITY_SERVICE: this app uses Accessibility services to automate the function (e.g. change display size), optional. It helps those who have difficulty in tapping and complete the task easier
