How to know if a device is a large one (physically)

I try to do something different if the device is a large one (like a iPad or Galaxy Tab) V.S. a small one like a mobile phone.

I am thinking to decide if a device is a large one by following code

local largeDevice = false local model = system.getInfo("model") if (string.find(model, "Pad") ~= nil) then -- it's iPad family     largeDevice = true else     local androidWidth = system.getInfo("androidDisplayWidthInInches")     if (androidWidth ~= nil and androidWidth \> 4) then  -- device over 4 inches          largeDevice = true     end end

Any suggestion? 

Thanks.

You can check the display.pixelHeight and display.pixelWidth to identify large screens. As far as large devices are concerned, I don’t know if there are any identifiers for actual in-hand size.

pixelHeight & pixelWidth? Are they related to physical size?

#4

No, they are related to screen size. It’s conceivable that you could assume a device is large if the pixelHeight/Width are large, but my Nexus 4 has a large pixelHeight but is significantly smaller than a Galaxy Tab, which has a smaller pixelHeight value. So you could assume, but it isn’t gospel.

Rob suggested this formula:

if ( system.getInfo( "androidDisplayWidthInInches" ) \> 5 or system.getInfo( "androidDisplayHeightInInches" ) \> 5 ) then --is a tablet print( "Is tablet" ) else print( "Is phone" ) end  

Not sure if this is a widely used convention, e.g. how does Google (admob) classifies devices (as Corona uses smartbanners, they are 50px high for phone and 90px for tablets).

I would give >6 because 5 is too close to current smart phones and some roundings would give you tablet instead smartphone
