How do I detect what hardware my app is running on? I mean the specific brand and model. I'm having the same problem with Droid. I wanted to manually size tiles at runtime to a minimum of 1cm, but it's not working because of this inaccurate value. Also, are you aware of any other devices that misreport their screen metrics? If so, will you provide a list?
