I would really like to have a command to find out what the current DPI/PPI is on a mobile device for automatically resizing the game's graphics to account for high res on a small screen or low res on a big screen.

This should be a really easy command to implement, shouldn't it, Paul?

*crosses fingers and hopes Paul actually sees this post*

This command should be available for us on both Android and iOS. It is really difficult to design nice UI without knowing pixel density!

Doesn't GetDeviceWidth() and GetDeviceHeight() work?

No. It returns pixels. We need pixel density.
The biggest use of this is with text and UI.

I want my test to be, say, 0.5 inches high on all devices.
This is impossible to do without knowing PPI.
Which means that I have to pick a percent or pixel size.
If I pick a percent, say 2%, it would make the font 24 pixels high on a Nexus 7 which would be 0.11 inches high.
On a Nexus 5 it would result in 0.05 inches high text which is impossible to read and won't render well.

Pixel density is extremely common to use in mobile development.

without this feature it can be a input option 5"/7"/10"/22".
today i wonder me why windows is by default 96 dpi because its
often wrong.
i have a paint tool that shows a bar and ask how long it is on screen
for calculate the dpi ...

Why do you assume I'm using T2? I can't do that in T1.

Hey guys.

I've come across this problem in the past and have figured out a solution. I have a function I use in most of my apps for returning "Screen DPI/PPI"
