Smaller UI and Larger Resolution

The Purpose

For using Android on large display, and reporting to mobile browser the physical resolution.

Scenario

• Android by default will report a low resolution (not physical resolution) to apps
• Which makes UI so big, font so big
  • Even when browser showing websites in its desktop mode, the resolution reported to websites are still small
    • On phone: Usually around 800px to 900px

The Work-around

• WARN:
  • THIS WORK-AROUND MAY BREAK THE FONT SIZE VS UI ON MANY APPS
  • USE IT CAREFULLY, HARD TO CHANGE BACK WHEN THE UI IS TOO SMALL TO PRESS WITH FINGERS.
• In order to have Android scaled to physical pixels, especially for using browsers in Android when using external display such as thru' Samsung Flow
  • Enable Developers mode in Android Settings
  • Go to 'Minimum width' in Developers settings
    • The default for Note8 is: 411 dp
    • But the physical display of Note8 is 2220x1080, so that minimum width must be the smaller size of physical resolution
    • However, the external display is Full HD for example
      • Thus put the minimum width to 1080? (of Full HD resolution 1920x1080)
      • But by practice 720 is better to be able see on mobile screen too?
• Bottom line:
  • Put Minimum width to 1080 for physical mobile display experience
  • Restore to 411 when needed.
  • Change the font size in Android Settings (not Developers Settings) too
    • Real physical resolution needs bigger font size. ___
