Question

Is there a way to get info about screen type in android? I want to know is device i am using amoled/ips/tft or get maximum brightness of screen, not relative brightness but brightness in nits or candelas/cm2

Answer 1

Much like other physical aspects of a device(weight, length, moment of inertia, etc.), this information will not be stored in the phone. I think the only way you could do this is to gather the information, create a database, and reference values to device IDs.

Edit: The only other thing I can think of is using the device's light sensor and some sort of calibration device/method. Something like:

• hold device x distance from a mirror/white surface in a pitch black room
• programmatically cycle the screen through brightness settings
• read light sensor at each step

The limitations here would be in the light sensor if it even exists and getting people to calibrate their device properly.

Answer 2

I don't think there's any way to do it directly, but you can get the device name using

android.os.Build.MODEL;

and then use this to do some sort of web service for the information you need.
