Is there anyway that I can get the device PPI?
See if this works:
var pixelRatio = window.devicePixelRatio || 1;
Thanks for your reply.
I experiment on a device with 480 x 800 screen resolution with 240ppi. So, the actual device screen size is 2 x 3.334 inch, which is a 4 inch device.
However, the window.devicePixelRatio
return the result of 1.5. How can I get the result of 240?
