Hi , I am using Google Chrome's Developer Tools to emulate different mobile and tablet device. My major interest is to find the device screen width and height in pixels.

I created a sample ASP.Net website and testing it using Google Chrome's device emulator. I am using the following capabilities from WURFL cloud to retrieve the device screen width and height in pixels.
1) resolution_width
2) resolution_height
3) max_image_width
4) max_image_height

The cloud service doesn't gives me correct results. Below are my results -

iphone 6 User Agent from Google device emulator is
Mozilla/5.0 (iPhone; CPU iPhone OS 8_0 like Mac OS X) AppleWebKit/600.1.3 (KHTML, like Gecko) Version/8.0 Mobile/12A4345d Safari/600.1.4
Google tells the screen size of iphone 6 is 375 x 667
But WURFL cloud gives me
1) resolution_width - 640
2) resolution_height - 960
3) max_image_width - 320
4) max_image_height - 480

Samsung Galaxy S4 User Agent from Google device emulator is
Mozilla/5.0 (Linux; Android 4.2.2; GT-I9505 Build/JDQ39) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.59 Mobile Safari/537.36
Google tells the screen size of Samsung Galaxy S4 is 360 x 640
But WURFL cloud gives me
1) resolution_width - 1080
2) resolution_height - 1920
3) max_image_width - 360
4) max_image_height - 400

I am not sure why there is a discrepancy in the device width and height. Please correct me if I am wrong. Is there any other capability I can use.

Hello,

We will be correcting the max_image_height for the Galaxy S4 and update the WURFL cloud to display the correct dimensions for this device. The dimensions for the iPhone 6 are returning 320 x 480 due to how Apple has decided to identify their devices. Unfortunately, they prevent the ability to detect the physical iOS model information using the User Agent alone. If you are interested in detecting the iOS model our WURFL.js solution would allow you to detect this.

Thank you,

Elliot
